63 | 64 | # Why? 🤷 65 | 66 | `Phoenix` is already an awesome web framework 67 | that helps teams build reliable Apps & APIs fast.
68 | `LiveView` takes the simplicity of building realtime features 69 | to the next level of elegance and simplicity. 70 | 71 | `LiveView` lets us create a slick single-page app 72 | with a **native** (_no lag or refresh_) experience 73 | without writing `JavaScript`. 74 | 75 | # What? 💭 76 | 77 | This tutorial builds a Todo List from scratch 78 | using Phoenix LiveView in _less_ than 20 minutes. 79 | 80 | # Who? 👤 81 | 82 | This tutorial is aimed at LiveView beginners 83 | who want to _understand_ how everything works 84 | using a familiar UI. 85 | 86 | If you are completely new to Phoenix and LiveView, 87 | we recommend you follow the **LiveView _Counter_ Tutorial**: 88 | https://github.com/dwyl/phoenix-liveview-counter-tutorial 89 | 90 | ## Prerequisites: What you Need _Before_ You Start 📝 91 | 92 | This tutorial expects you have a `Elixir`, `Phoenix` and `Node.js` installed. 93 | If you don't already have them on your computer, 94 | please see: 95 | https://github.com/dwyl/learn-elixir#installation 96 | and 97 | https://hexdocs.pm/phoenix/installation.html#phoenix 98 | 99 | # How? 💻 100 | 101 | > 💡 You can also try the version deployed to Heroku: 102 | > https://live-view-todo.herokuapp.com/ 103 | 104 |
105 | 106 | ## Step 0: Run the _Finished_ Todo App on your `localhost` 🏃‍ 107 | 108 | Before you attempt to _build_ the todo list app, 109 | we suggest that you clone and _run_ 110 | the complete app on your `localhost`.
111 | That way you _know_ it's working 112 | without much effort/time expended. 113 | 114 | ### Clone the Repository 115 | 116 | On your `localhost`, 117 | run the following command to clone the repo 118 | and change into the directory: 119 | 120 | ```sh 121 | git clone https://github.com/dwyl/phoenix-liveview-todo-list-tutorial.git 122 | cd phoenix-liveview-todo-list-tutorial 123 | ``` 124 | 125 | ### _Download_ the Dependencies 126 | 127 | Install the dependencies by running the command: 128 | 129 | ```sh 130 | mix setup 131 | ``` 132 | 133 | It will take a few seconds to download the dependencies 134 | depending on the speed of your internet connection; 135 | be 136 | [patient](https://user-images.githubusercontent.com/194400/76169853-58139380-6174-11ea-8e03-4011815758d0.png). 137 | 😉 138 | 139 | ### _Run_ the App 140 | 141 | Start the Phoenix server by running the command: 142 | 143 | ```sh 144 | mix phx.server 145 | ``` 146 | 147 | Now you can visit 148 | [`localhost:4000`](http://localhost:4000) 149 | in your web browser. 150 | 151 | > 💡 Open a _second_ browser window (_e.g. incognito mode_), 152 | > you will see the the counter updating in both places like magic! 153 | 154 | You should expect to see: 155 | 156 | 161 | 162 | With the _finished_ version of the App running on your machine 163 | and a clear picture of where we are headed, it's time to _build_ it! 164 | 165 |
166 | 167 | ## Step 1: Create the App 🆕 168 | 169 | In your terminal run the following `mix` command 170 | to generate the new Phoenix app: 171 | 172 | ```sh 173 | mix phx.new live_view_todo 174 | ``` 175 | 176 | This command will setup the dependencies (including the liveView dependencies) 177 | and boilerplate for us to get going as fast as possible. 178 | 179 | When you see the following prompt in your terminal: 180 | 181 | ```sh 182 | Fetch and install dependencies? [Yn] 183 | ``` 184 | 185 | Type Y followed by the Enter key. 186 | That will download all the necessary dependencies. 187 | 188 | ### Checkpoint 1a: _Run_ the _Tests_! 189 | 190 | In your terminal, go into the newly created app folder using: 191 | 192 | ```sh 193 | cd live_view_todo 194 | ``` 195 | 196 | And then run the following `mix` command: 197 | 198 | ```sh 199 | mix test 200 | ``` 201 | 202 | After the application is compiled you should see: 203 | 204 | ``` 205 | ... 206 | 207 | Finished in 0.1 seconds (0.08s async, 0.05s sync) 208 | 3 tests, 0 failures 209 | ``` 210 | 211 | Tests all pass. 212 | This is _expected_ with a new app. 213 | It's a good way to confirm everything is working. 214 | 215 |
216 | 217 | ### Checkpoint 1b: _Run_ the New Phoenix App! 218 | 219 | Run the server by executing this command: 220 | 221 | ```sh 222 | mix phx.server 223 | ``` 224 | 225 | Visit 226 | [`localhost:4000`](http://localhost:4000) 227 | in your web browser. 228 | 229 | ![welcome-to-phoenix-liveview](https://user-images.githubusercontent.com/194400/95674046-99a26c00-0ba5-11eb-94e8-eec6840035a0.png) 230 | 231 | > 🏁 Snapshot of code at the end of Step 1: 232 | > [`#25ba4e7`](https://github.com/dwyl/phoenix-liveview-todo-list-tutorial/commit/25ba4e75cee1dd038fff71aa1ba4b17330d692c9) 233 | 234 |
235 | 236 | ## 2. Create the TodoMVC UI/UX 237 | 238 | As we saw in the previous step, our App looks like a fresh Phoenix App. 239 | Let's make it look like a todo list. 240 | 241 | ### 2.1 Create live folder 242 | 243 | By convention Phoenix uses a `live` folder to manage the LiveView files. 244 | Create this folder at `lib/live_view_todo_web/live`. 245 | 246 | Next we can create the `PageLive` controller module. Create the 247 | `lib/live_view_todo_web/live/page_live.ex` and add the following content: 248 | 249 | ```elixir 250 | defmodule LiveViewTodoWeb.PageLive do 251 | use LiveViewTodoWeb, :live_view 252 | 253 | @impl true 254 | def mount(_params, _session, socket) do 255 | {:ok, socket} 256 | end 257 | end 258 | ``` 259 | 260 | When using LiveView, the controller is required to implement 261 | the [`mount`](https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html#c:mount/3) function, 262 | the entry point of the live page. 263 | 264 | ### 2.2 Update the Root Layout 265 | 266 | Open the `lib/live_view_todo_web/templates/layout/root.html.heex` file 267 | and remove the `
` section 268 | such that the contents file is the following: 269 | 270 | ```html 271 | 272 | 273 | 274 | 275 | 276 | 277 | <%= csrf_meta_tag() %> 278 | <%= live_title_tag assigns[:page_title] || "LiveViewTodo", suffix: " · Phoenix Framework" %> 279 | 280 | 281 | 282 | 283 | <%= @inner_content %> 284 | 285 | 286 | ``` 287 | ### 2.3 Create the page_live layout 288 | 289 | Create the `lib/live_view_todo_web/live/page_live.html.heex` layout file and 290 | add the following content: 291 | 292 | ```html 293 |

336 | ``` 337 | 338 | 339 | > **Note**: we borrowed this code from: 340 | > https://github.com/dwyl/phoenix-todo-list-tutorial#3-create-the-todomvc-uiux 341 | > our `Phoenix` (_without `LiveView`_) Todo List Tutorial. 342 | 343 | ### 2.4 Update Router and controller 344 | 345 | in `lib/live_view_todo_web/router.ex` file 346 | change `get` to `live` and rename the controller 347 | `PageController` to `PageLive` 348 | 349 | from: 350 | 351 | ```elixir 352 | scope "/", LiveViewTodoWeb do 353 | pipe_through :browser 354 | 355 | get "/", PageController, :index 356 | end 357 | ``` 358 | 359 | to: 360 | 361 | ```elixir 362 | scope "/", LiveViewTodoWeb do 363 | pipe_through :browser 364 | 365 | live "/", PageLive 366 | end 367 | ``` 368 | 369 | If you attempt to run the app now 370 | `mix phx.server` and visit 371 | [http://localhost:4000](http://localhost:4000)
372 | You will see this (_without the TodoMVC `CSS`_): 373 | 374 | ![before-adding-css](https://user-images.githubusercontent.com/194400/95677403-420ffa80-0bbd-11eb-9901-0604e08c6974.png) 375 | 376 | That's obviously not what we want, 377 | so let's get the TodoMVC `CSS` 378 | and save it in our project! 379 | 380 | ## 2.5 Save the TodoMVC CSS to `/assets/css` 381 | 382 | Visit 383 | https://todomvc.com/examples/vanillajs/node_modules/todomvc-app-css/index.css
384 | and save the file to `/assets/css/todomvc-app.css` 385 | 386 | e.g: 387 | [`/assets/css/todomvc-app.css`](https://github.com/dwyl/phoenix-todo-list-tutorial/blob/65bec23b92307527a414f77b667b29ea10619e5a/assets/css/todomvc-app.css) 388 | 389 |
390 | 391 | ## 2.6 Import the `todomvc-app.css` in `app.scss` 392 | 393 | Open the `assets/css/app.scss` file and replace it with the following: 394 | 395 | ```css 396 | /* This file is for your main application css. */ 397 | /* @import "./phoenix.css"; */ 398 | @import "./todomvc-app.css"; 399 | ``` 400 | 401 | We also commented out the line 402 | `@import "./phoenix.css";` 403 | because we don't want the Phoenix (Milligram) styles 404 | _conflicting_ with the TodoMVC ones. 405 | 406 | At the end of this step, 407 | if you run your Phoenix App with 408 | `mix phx.server` 409 | and visit: 410 | [http://localhost:4000](http://localhost:4000) 411 | you should see the following: 412 | 413 | ![todo-list-ui](https://user-images.githubusercontent.com/194400/95678014-7f768700-0bc1-11eb-8728-5eae33cbb560.png) 414 | 415 | Now that we have the layout looking like we want it, 416 | we can move onto the fun part of making it _work_. 417 | 418 | ## 2.7 Update the test 419 | 420 | Now that we have a functioning LiveView page, let's create the tests under 421 | `test/live_view_todo_web/live` folder. Create the file 422 | `test/live_view_todo_web/live/page_live_test.exs` and add the following: 423 | 424 | ```elixir 425 | defmodule LiveViewTodoWeb.PageLiveTest do 426 | use LiveViewTodoWeb.ConnCase 427 | import Phoenix.LiveViewTest 428 | 429 | test "disconnected and connected mount", %{conn: conn} do 430 | {:ok, page_live, disconnected_html} = live(conn, "/") 431 | assert disconnected_html =~ "Todo" 432 | assert render(page_live) =~ "What needs to be done" 433 | end 434 | end 435 | ``` 436 | 437 | and delete the `test/live_view_todo_web/controllers/page_controller_test.exs` file. 438 | 439 | 440 | Now when you re-run the tests: 441 | 442 | ```sh 443 | mix test 444 | ``` 445 | 446 | You should see: 447 | 448 | ```sh 449 | Compiling 1 file (.ex) 450 | ... 451 | 452 | Finished in 0.2 seconds 453 | 3 tests, 0 failures 454 | ``` 455 | 456 | Everything passing, lets get back to building! 457 | 458 |

Create the Todo List `items` Schema 461 | 462 | In order to _store_ the todo list `items` we need a schema. 463 | In your terminal run the following generator command: 464 | 465 | ```sh 466 | mix phx.gen.schema Item items text:string person_id:integer status:integer 467 | ``` 468 | 469 | That will create two new files: 470 | 471 | - `lib/live_view_todo/item.ex` - the schema 472 | - `priv/repo/migrations/20201227070700_create_items.exs` - migration file (creates database table) 473 | 474 | Open the migration file to add a default value to `status`: 475 | 476 | ```elixir 477 | add :status, :integer, default: 0 # add default value 0 478 | ``` 479 | 480 | Reference: 481 | https://hexdocs.pm/phoenix/Mix.Tasks.Phx.Gen.Schema.html 482 | 483 | Execute the migration file by running the following command: 484 | 485 | ```sh 486 | mix ecto.migrate 487 | ``` 488 | 489 | You will see output similar to the following: 490 | 491 | ```sh 492 | 13:44:03.406 [info] == Migrated 20170606070700 in 0.0s 493 | ``` 494 | 495 | Now that the schema has been created 496 | we can write some code 497 | to make the todo list functionality work. 498 | 499 | ### 3.1 Add Aliases to `item.ex` 500 | 501 | Before we create any new functions, let's open the 502 | `lib/live_view_todo/item.ex` 503 | file and make a couple of changes: 504 | 505 | ```elixir 506 | defmodule LiveViewTodo.Item do 507 | use Ecto.Schema 508 | import Ecto.Changeset 509 | 510 | schema "items" do 511 | field :person_id, :integer 512 | field :status, :integer 513 | field :text, :string 514 | 515 | timestamps() 516 | end 517 | 518 | @doc false 519 | def changeset(item, attrs) do 520 | item 521 | |> cast(attrs, [:text, :person_id, :status]) 522 | |> validate_required([:text, :person_id, :status]) 523 | end 524 | end 525 | ``` 526 | 527 | First add the line `alias LiveViewTodo.Repo` 528 | below the `import Ecto.Changeset` statement; 529 | we need this alias so that we can make database queries. 530 | 531 | Next add the line `alias __MODULE__` below the `alias` we just added; 532 | this just means "alias the Struct contained in this file so we can reference it". 533 | see: https://stackoverflow.com/questions/39854281/access-struct-inside-module/47501059 534 | 535 | Then add the default value for `status` to `0`: 536 | 537 | ```elixir 538 | field :status, :integer, default: 0 539 | ``` 540 | 541 | Finally remove the `:person_id, :status` 542 | from the List of fields in `validate_required`. 543 | We don't want `person_id` to be required for now 544 | as we don't yet have authentication setup for the App. 545 | 546 | Your file should now look like this: 547 | 548 | ```elixir 549 | defmodule LiveViewTodo.Item do 550 | use Ecto.Schema 551 | import Ecto.Changeset 552 | alias LiveViewTodo.Repo 553 | alias __MODULE__ 554 | 555 | schema "items" do 556 | field :person_id, :integer 557 | field :status, :integer 558 | field :text, :string 559 | 560 | timestamps() 561 | end 562 | 563 | @doc false 564 | def changeset(item, attrs) do 565 | item 566 | |> cast(attrs, [:text, :person_id, :status]) 567 | |> validate_required([:text]) 568 | end 569 | end 570 | ``` 571 | 572 | With those changes made, we can proceed to creating our functions. 573 | 574 | ### 3.2 Create Todo Item CRUD Tests 575 | 576 | The `phx.gen.schema` does not automatically create any 577 | ["CRUD"](https://en.wikipedia.org/wiki/Create,_read,_update_and_delete) 578 | functions 579 | to `Create` an `item` or `Read` `items` in/from the database 580 | or tests for those functions, 581 | so we need to create them ourselves now. 582 | 583 | Create a new directory with the path: 584 | `test/live_view_todo` 585 | and in that new directory, 586 | create a file: 587 | `test/live_view_todo/item_test.exs` 588 | 589 | Next _open_ the newly created file 590 | `test/live_view_todo/item_test.exs` 591 | and add the following test code to it: 592 | 593 | ```elixir 594 | defmodule LiveViewTodo.ItemTest do 595 | use LiveViewTodo.DataCase 596 | alias LiveViewTodo.Item 597 | 598 | describe "items" do 599 | @valid_attrs %{text: "some text", person_id: 1, status: 0} 600 | @update_attrs %{text: "some updated text", status: 1} 601 | @invalid_attrs %{text: nil} 602 | 603 | def item_fixture(attrs \\ %{}) do 604 | {:ok, item} = 605 | attrs 606 | |> Enum.into(@valid_attrs) 607 | |> Item.create_item() 608 | 609 | item 610 | end 611 | 612 | test "get_item!/1 returns the item with given id" do 613 | item = item_fixture(@valid_attrs) 614 | assert Item.get_item!(item.id) == item 615 | end 616 | 617 | test "create_item/1 with valid data creates a item" do 618 | assert {:ok, %Item{} = item} = Item.create_item(@valid_attrs) 619 | assert item.text == "some text" 620 | 621 | inserted_item = List.first(Item.list_items()) 622 | assert inserted_item.text == @valid_attrs.text 623 | end 624 | 625 | test "create_item/1 with invalid data returns error changeset" do 626 | assert {:error, %Ecto.Changeset{}} = Item.create_item(@invalid_attrs) 627 | end 628 | 629 | test "list_items/0 returns a list of todo items stored in the DB" do 630 | item1 = item_fixture() 631 | item2 = item_fixture() 632 | items = Item.list_items() 633 | assert Enum.member?(items, item1) 634 | assert Enum.member?(items, item2) 635 | end 636 | 637 | test "update_item/2 with valid data updates the item" do 638 | item = item_fixture() 639 | assert {:ok, %Item{} = item} = Item.update_item(item, @update_attrs) 640 | assert item.text == "some updated text" 641 | end 642 | end 643 | end 644 | ``` 645 | 646 | Take a moment to _understand_ what is being tested. 647 | Once you have written out (_or let's face it, copy-pasted_) the test code, 648 | save the file and run the tests: 649 | 650 | ``` 651 | mix test test/live_view_todo/item_test.exs 652 | ``` 653 | 654 | Since the functions don't yet exist, 655 | you will see all the test _fail_: 656 | 657 | ``` 658 | 1) test items get_item!/1 returns the item with given id (LiveViewTodo.ItemTest) 659 | test/live_view_todo/item_test.exs:19 660 | ** (UndefinedFunctionError) function LiveViewTodo.Item.create_item/1 is undefined or private 661 | code: item = item_fixture(@valid_attrs) 662 | stacktrace: 663 | (live_view_todo 0.1.0) LiveViewTodo.Item.create_item(%{person_id: 1, text: "some text"}) 664 | test/live_view_todo/item_test.exs:14: LiveViewTodo.ItemTest.item_fixture/1 665 | test/live_view_todo/item_test.exs:20: (test) 666 | 667 | etc ... 668 | 669 | Finished in 0.2 seconds 670 | 5 tests, 5 failures 671 | ``` 672 | 673 | Hopefully these CRUD tests are familiar to you. 674 | If they aren't, please read: 675 | https://hexdocs.pm/phoenix/testing.html
676 | If you still have any doubts, please 677 | [ask a specific question](https://github.com/dwyl/phoenix-liveview-todo-list-tutorial/issues/new). 678 | 679 | The focus of this tutorial is `LiveView` not CRUD testing, 680 | the sooner we get to the `LievView` part the better, 681 | this is just the "setup" we need to do for inserting todo item data. 682 | 683 | Let's write the functions to make the tests pass! 684 | 685 | ### 3.3 Make the CRUD Tests _Pass_ 686 | 687 | Open the `lib/live_view_todo/item.ex` file 688 | and add the following lines of code: 689 | 690 | ```elixir 691 | @doc """ 692 | Creates a item. 693 | 694 | ## Examples 695 | 696 | iex> create_item(%{text: "Learn LiveView"}) 697 | {:ok, %Item{}} 698 | 699 | iex> create_item(%{text: nil}) 700 | {:error, %Ecto.Changeset{}} 701 | 702 | """ 703 | def create_item(attrs \\ %{}) do 704 | %Item{} 705 | |> changeset(attrs) 706 | |> Repo.insert() 707 | end 708 | 709 | @doc """ 710 | Gets a single item. 711 | 712 | Raises `Ecto.NoResultsError` if the Item does not exist. 713 | 714 | ## Examples 715 | 716 | iex> get_item!(123) 717 | %Item{} 718 | 719 | iex> get_item!(456) 720 | ** (Ecto.NoResultsError) 721 | 722 | """ 723 | def get_item!(id), do: Repo.get!(Item, id) 724 | 725 | 726 | @doc """ 727 | Returns the list of items. 728 | 729 | ## Examples 730 | 731 | iex> list_items() 732 | [%Item{}, ...] 733 | 734 | """ 735 | def list_items do 736 | Repo.all(Item) 737 | end 738 | 739 | @doc """ 740 | Updates a item. 741 | 742 | ## Examples 743 | 744 | iex> update_item(item, %{field: new_value}) 745 | {:ok, %Item{}} 746 | 747 | iex> update_item(item, %{field: bad_value}) 748 | {:error, %Ecto.Changeset{}} 749 | 750 | """ 751 | def update_item(%Item{} = item, attrs) do 752 | item 753 | |> Item.changeset(attrs) 754 | |> Repo.update() 755 | end 756 | ``` 757 | 758 | After saving the `item.ex` file, 759 | re-run the tests with: 760 | 761 | ```sh 762 | mix test test/live_view_todo/item_test.exs 763 | ``` 764 | 765 | You should see them pass: 766 | 767 | ```sh 768 | ..... 769 | 770 | Finished in 0.2 seconds 771 | 5 tests, 0 failures 772 | 773 | Randomized with seed 208543 774 | ``` 775 | 776 | Now that we have our CRUD functions written (_and documented+tested_), 777 | we can move on to the _fun_ part, building the Todo App in `LiveView`! 778 | 779 |
780 | 781 | ## 4. Handle Todo List `Item` Creation 782 | 783 | The first event we want to handle in our `LiveView` App is "create"; 784 | the act of creating a new Todo List `item`. 785 | 786 | Let's start by adding a _test_ for creating an item. 787 | Open the 788 | `test/live_view_todo_web/live/page_live_test.exs` 789 | file and add the following test: 790 | 791 | ```elixir 792 | test "connect and create a todo item", %{conn: conn} do 793 | {:ok, view, _html} = live(conn, "/") 794 | assert render_submit(view, :create, %{"text" => "Learn Elixir"}) =~ "Learn Elixir" 795 | end 796 | ``` 797 | 798 | Docs for this LiveView testing using `render_submit/1`: 799 | https://hexdocs.pm/phoenix_live_view/Phoenix.LiveViewTest.html#render_submit/1 800 | 801 |
802 | 803 | If you attempt to run this test: 804 | 805 | ```sh 806 | mix test test/live_view_todo_web/live/page_live_test.exs 807 | ``` 808 | 809 | you will see it _fail_: 810 | 811 | ```sh 812 | 1) test connect and create a todo item (LiveViewTodoWeb.PageLiveTest) 813 | test/live_view_todo_web/live/page_live_test.exs:12 814 | ** (EXIT from #PID<0.441.0>) an exception was raised: 815 | 816 | ** (FunctionClauseError) no function clause matching in LiveViewTodoWeb.PageLive.handle_event/3 817 | ``` 818 | 819 | In order to make the test _pass_ we will need to add two blocks of code. 820 | 821 | Open the `lib/live_view_todo_web/live/page_live.html.heex` file 822 | and locate the line in the `
` section: 823 | 824 | ```html 825 | 826 | ``` 827 | 828 | Replace it with the following: 829 | 830 | ```html 831 |
832 | 841 |
842 | ``` 843 | 844 | The important part is the `phx-submit="create"` 845 | which tells `LiveView` which event to emit when the form is submitted. 846 | 847 | Once you've saved the `page_live.html.leex` file, 848 | open the `lib/live_view_todo_web/live/page_live.ex` file 849 | and under `use LiveViewTodoWeb, :live_view` add 850 | 851 | ```elixir 852 | alias LiveViewTodo.Item 853 | 854 | @topic "live" 855 | 856 | ``` 857 | 858 | 859 | and the add the following handler code after the `mount` function: 860 | 861 | ```elixir 862 | 863 | @impl true 864 | def handle_event("create", %{"text" => text}, socket) do 865 | Item.create_item(%{text: text}) 866 | socket = assign(socket, items: Item.list_items(), active: %Item{}) 867 | LiveViewTodoWeb.Endpoint.broadcast_from(self(), @topic, "update", socket.assigns) 868 | {:noreply, socket} 869 | end 870 | ``` 871 | 872 | The `@topic "live"` is the WebSocket (_Phoenix Channel_) topic 873 | defined as a 874 | [module attribute](https://elixir-lang.org/getting-started/module-attributes.html) 875 | (_like a Global Constant_), 876 | which we will use to both subscribe to and broadcast on. 877 | 878 | So the following line: 879 | 880 | ```elixir 881 | LiveViewTodoWeb.Endpoint.broadcast_from(self(), @topic, "update", socket.assigns) 882 | ``` 883 | 884 | Will send the "update" event with the `socket.assigns` data 885 | to all the other clients on listening to the @topic. 886 | Now to listen to this message we can define the [handle_info](https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html#c:handle_info/2) callback. 887 | Add the following code: 888 | 889 | ```elixir 890 | @impl true 891 | def handle_info(%{event: "update", payload: %{items: items}}, socket) do 892 | {:noreply, assign(socket, items: items)} 893 | end 894 | ``` 895 | 896 | We are using pattern matching on the first parameter to make sure 897 | the handle_info matches the "update" event. We then assign to the socket 898 | the new list of items. 899 | 900 | 901 | With that in place you can now create items in the browser! 902 | Run the app: `mix phx.sever` and you should be able to add items. 903 | _However_ they will not _appear_ in the UI. 904 | Let's fix that next. 905 | 906 |
907 | 908 | ## 5. _Show_ the Created Todo `Items` 909 | 910 | In order to _show_ the Todo `items` we are creating, 911 | we need to: 912 | 913 | 1. Lookup and assign the `items` in the `mount/3` function 914 | 2. Loop through and render the `item` in the `page_live.html.leex` template 915 | 916 | Let's start by updating the `mount/3` function in 917 | `/lib/live_view_todo_web/live/page_live.ex`: 918 | 919 | ```elixir 920 | def mount(_params, _session, socket) do 921 | # subscribe to the channel 922 | if connected?(socket), do: LiveViewTodoWeb.Endpoint.subscribe(@topic) 923 | {:ok, assign(socket, items: Item.list_items())} # add items to assigns 924 | end 925 | ``` 926 | 927 | Then in the 928 | `lib/live_view_todo_web/live/page_live.html.leex` file 929 | replace the code: 930 | 931 | ```html 932 | 948 | ``` 949 | 950 | With the following: 951 | 952 | ```elixir 953 | 968 | ``` 969 | 970 | You will notice that there are two functions 971 | `completed?/1` and `checked?/1` 972 | invoked in that block of template code. 973 | 974 | We need to define the functions in 975 | `/lib/live_view_todo_web/live/page_live.ex`: 976 | 977 | ```elixir 978 | def checked?(item) do 979 | not is_nil(item.status) and item.status > 0 980 | end 981 | 982 | def completed?(item) do 983 | if not is_nil(item.status) and item.status > 0, do: "completed", else: "" 984 | end 985 | ``` 986 | 987 | These are convenience functions. 988 | We _could_ have embedded this code directly in the template, 989 | however we prefer to _minimize_ logic in the templates 990 | so that they are easier to read/maintain. 991 | 992 | With that template update and helper functions saved, 993 | we can now create and _see_ our created Todo `item`: 994 | 995 | ![todo-items-create](https://user-images.githubusercontent.com/194400/96370930-718fab80-1157-11eb-9e8a-24b4548fcf1c.png) 996 | 997 |
998 | 999 | ## 6. Toggle the State of Todo Items 1000 | 1001 | The next piece of functionality we want in a Todo List 1002 | is the ability to **`toggle`** the completion from "todo" to "done". 1003 | 1004 | In our `item` `schema` (created in step 3), 1005 | we defined `status` as an `integer`. 1006 | The `default` value for `item.status` 1007 | when a **new `item`** is inserted is `0`. 1008 | 1009 |
1010 | 1011 | Let's create a (_failing_) test for **toggling** items. 1012 | Open the 1013 | `test/live_view_todo_web/live/page_live_test.exs` 1014 | file and add the following test to it: 1015 | 1016 | ```elixir 1017 | test "toggle an item", %{conn: conn} do 1018 | {:ok, item} = Item.create_item(%{"text" => "Learn Elixir"}) 1019 | assert item.status == 0 1020 | 1021 | {:ok, view, _html} = live(conn, "/") 1022 | assert render_click(view, :toggle, %{"id" => item.id, "value" => 1}) =~ "completed" 1023 | 1024 | updated_item = Item.get_item!(item.id) 1025 | assert updated_item.status == 1 1026 | end 1027 | ``` 1028 | 1029 | Make sure to alias the `Item` structure in your test file: 1030 | 1031 | ```elixir 1032 | defmodule LiveViewTodoWeb.PageLiveTest do 1033 | use LiveViewTodoWeb.ConnCase 1034 | import Phoenix.LiveViewTest 1035 | alias LiveViewTodo.Item # alias Item here 1036 | ``` 1037 | 1038 | You may have noticed that in the template, 1039 | we included an `` with the `type="checkbox"` 1040 | 1041 | ```elixir 1042 | <%= if checked?(item) do %> 1043 | 1044 | <% else %> 1045 | 1046 | <% end %> 1047 | ``` 1048 | 1049 | These lines of code already has everything we need to enable the **`toggle`** feature 1050 | on the front-end, we just need to create a handler in `page_live.ex` 1051 | to handle the event. 1052 | 1053 | Open the 1054 | `/lib/live_view_todo_web/live/page_live.ex` 1055 | file and add the following code to it: 1056 | 1057 | ```elixir 1058 | @impl true 1059 | def handle_event("toggle", data, socket) do 1060 | status = if Map.has_key?(data, "value"), do: 1, else: 0 1061 | item = Item.get_item!(Map.get(data, "id")) 1062 | Item.update_item(item, %{id: item.id, status: status}) 1063 | socket = assign(socket, items: Item.list_items(), active: %Item{}) 1064 | LiveViewTodoWeb.Endpoint.broadcast(@topic, "update", socket.assigns) 1065 | {:noreply, socket} 1066 | end 1067 | ``` 1068 | 1069 | Note that we are using `broadcast/3` instead of `broadcast_from/4` to make 1070 | sure the count of items left is updated for the client itself. 1071 | 1072 | Once you've saved the file, 1073 | the test will pass. 1074 | 1075 |
1076 | 1077 | ## 7. "Delete" a Todo `item` 1078 | 1079 | Rather than _permanently_ deleting items which destroys history/accountability, 1080 | we prefer to 1081 | ["_soft deletion_"](https://en.wiktionary.org/wiki/soft_deletion) 1082 | which allows people to "undo" the operation. 1083 | 1084 | Open 1085 | `test/live_view_todo/item_test.exs` 1086 | and add the following test to it: 1087 | 1088 | ```elixir 1089 | test "delete_item/1 soft-deletes an item" do 1090 | item = item_fixture() 1091 | assert {:ok, %Item{} = deleted_item} = Item.delete_item(item.id) 1092 | assert deleted_item.status == 2 1093 | end 1094 | ``` 1095 | 1096 | If you attempt to run the test, 1097 | you will see it _fail_: 1098 | 1099 | ```sh 1100 | 1) test items delete_item/1 soft-deltes an item (LiveViewTodo.ItemTest) 1101 | test/live_view_todo/item_test.exs:50 1102 | ** (UndefinedFunctionError) function LiveViewTodo.Item.delete_item/1 is undefined or private 1103 | code: assert {:ok, %Item{} = deleted_item} = Item.delete_item(item.id) 1104 | stacktrace: 1105 | (live_view_todo 0.1.0) LiveViewTodo.Item.delete_item(157) 1106 | test/live_view_todo/item_test.exs:52: (test) 1107 | ``` 1108 | 1109 | To make the test _pass_, 1110 | open your `lib/live_view_todo/item.ex` file 1111 | and add the following function definition: 1112 | 1113 | ```elixir 1114 | def delete_item(id) do 1115 | get_item!(id) 1116 | |> Item.changeset(%{status: 2}) 1117 | |> Repo.update() 1118 | end 1119 | ``` 1120 | 1121 | Having defined the `delete/1` function 1122 | as updating the `item.status` to **`2`**, 1123 | we can now create a test for a `LiveView` handler 1124 | that invokes this function. 1125 | 1126 | Open the 1127 | `test/live_view_todo_web/live/page_live_test.exs` 1128 | file and add the following test to it: 1129 | 1130 | ```elixir 1131 | test "delete an item", %{conn: conn} do 1132 | {:ok, item} = Item.create_item(%{"text" => "Learn Elixir"}) 1133 | assert item.status == 0 1134 | 1135 | {:ok, view, _html} = live(conn, "/") 1136 | assert render_click(view, :delete, %{"id" => item.id}) 1137 | 1138 | updated_item = Item.get_item!(item.id) 1139 | assert updated_item.status == 2 1140 | end 1141 | ``` 1142 | 1143 | To make this test pass, 1144 | we need to add the following `handle_event/3` handler to `page_live.ex`: 1145 | 1146 | ```elixir 1147 | @impl true 1148 | def handle_event("delete", data, socket) do 1149 | Item.delete_item(Map.get(data, "id")) 1150 | socket = assign(socket, items: Item.list_items(), active: %Item{}) 1151 | LiveViewTodoWeb.Endpoint.broadcast(@topic, "update", socket.assigns) 1152 | {:noreply, socket} 1153 | end 1154 | ``` 1155 | 1156 | This point we've written a bunch of code, 1157 | let's see it in _action_ in the front-end. 1158 | 1159 | Run the Phoenix Sever: `mix phx.server` 1160 | and visit 1161 | [http://localhost:4000](http://localhost:4000) 1162 | in your web browser. 1163 | You should see: 1164 | 1165 | ![liveview-todo-delete](https://user-images.githubusercontent.com/194400/96378407-9b5ec780-1183-11eb-971d-94988352a0cf.gif) 1166 | 1167 |
1168 | 1169 | ## 8. Editing Todo `item.text` 1170 | 1171 | For _editing_ an `item` we'll continue to use `LiveView` and: 1172 | 1173 | - 1. Display the "**edit**" form when an `item` is clicked on 1174 | - 2. On submit, `LiveView` will handle the **`update-item`** event to **update** the `item` 1175 | 1176 | First we want to **update** the `html` to display the `form` when an `item` is edited: 1177 | 1178 | update `lib/live_view_todo_web/live/page_live.html.heex` to display the form: 1179 | 1180 | ```html 1181 | 1210 | ``` 1211 | 1212 | For each `item` we check 1213 | if the `item.id` 1214 | matches the `@editing` value 1215 | and we display 1216 | either the `form` or the `label` value. 1217 | 1218 | We have added the `phx-click="edit-item"` event on the `label` which is used 1219 | to define the `@editing` value: 1220 | 1221 | in `lib/live_view_todo_web/live/page_live.ex` create the logic for `edit-item` event: 1222 | 1223 | ```elixir 1224 | @impl true 1225 | def handle_event("edit-item", data, socket) do 1226 | {:noreply, assign(socket, editing: String.to_integer(data["id"]))} 1227 | end 1228 | ``` 1229 | 1230 | We assign the `editing` value 1231 | to the socket with the `item.id` 1232 | defined by 1233 | `phx-value-id`. 1234 | 1235 | Finally we can handle the `phx-submit="update-item"` event: 1236 | 1237 | ```elixir 1238 | @impl true 1239 | def handle_event("update-item", %{"id" => item_id, "text" => text}, socket) do 1240 | current_item = Item.get_item!(item_id) 1241 | Item.update_item(current_item, %{text: text}) 1242 | items = Item.list_items() 1243 | socket = assign(socket, items: items, editing: nil) 1244 | LiveViewTodoWeb.Endpoint.broadcast_from(self(), @topic, "update", socket.assigns) 1245 | {:noreply, socket} 1246 | end 1247 | ``` 1248 | 1249 | We update the item matching the id with the new text value and broadcast the change 1250 | to the other connected clients. 1251 | 1252 | Let's update the tests to make sure the editing feature is covered: 1253 | 1254 | ```elixir 1255 | test "edit item", %{conn: conn} do 1256 | {:ok, item} = Item.create_item(%{"text" => "Learn Elixir"}) 1257 | 1258 | {:ok, view, _html} = live(conn, "/") 1259 | 1260 | assert render_click(view, "edit-item", %{"id" => Integer.to_string(item.id)}) =~ 1261 | "
" 1262 | end 1263 | 1264 | test "update an item", %{conn: conn} do 1265 | {:ok, item} = Item.create_item(%{"text" => "Learn Elixir"}) 1266 | 1267 | {:ok, view, _html} = live(conn, "/") 1268 | 1269 | assert render_submit(view, "update-item", %{"id" => item.id, "text" => "Learn more Elixir"}) =~ 1270 | "Learn more Elixir" 1271 | 1272 | updated_item = Item.get_item!(item.id) 1273 | assert updated_item.text == "Learn more Elixir" 1274 | end 1275 | ``` 1276 | 1277 | The first test ensures the form is displayed when the `edit-item` event is triggered 1278 | is sent to the LiveView. 1279 | The second test, make sure the item value is updated when the edit form is submitted. 1280 | 1281 | 1282 | ### UI enhancement 1283 | 1284 | We can make the UI a bit better by adding focus to the edited item using 1285 | [Hooks](https://hexdocs.pm/phoenix_live_view/js-interop.html#client-hooks-via-phx-hook) 1286 | 1287 | On the template add a new attribute `phx-hook`: 1288 | 1289 | ```html 1290 | 1299 | ``` 1300 | 1301 | Then in `app.js` add the following: 1302 | 1303 | ```js 1304 | function focusInput(input) { 1305 | let end = input.value.length; 1306 | input.setSelectionRange(end, end); 1307 | input.focus(); 1308 | } 1309 | 1310 | 1311 | let Hooks = {} 1312 | Hooks.FocusInputItem = { 1313 | mounted() { 1314 | focusInput(document.getElementById("update_todo")); 1315 | }, 1316 | updated() { 1317 | focusInput(document.getElementById("update_todo")); 1318 | } 1319 | } 1320 | ``` 1321 | 1322 | the function `focusInput` add the focus to the input and place the cursor 1323 | at the end of the text. 1324 | 1325 | We use this function in the `mounted` and `updated` hooks event, `mounted` for the 1326 | first time the input is displayed, then `updated` when the input is dispalayed 1327 | again for editing other items. 1328 | 1329 | Finally we need to pass our `Hooks` object to the socket: 1330 | 1331 | ```js 1332 | let liveSocket = new LiveSocket("/live", Socket, { params: { _csrf_token: csrfToken }, hooks: Hooks }) 1333 | ``` 1334 | 1335 | 1336 | borrow from: https://github.com/dwyl/phoenix-todo-list-tutorial#8-edit-an-item 1337 | 1338 |
1339 | 1340 | ## 9. Footer Navigation 1341 | 1342 | In this section we'll update the footer links "All", "Active" and "Completed" 1343 | to make sure the `LiveView` displays only the `items` with the correct status. 1344 | 1345 | We first need to update the templates `lib/live_view_todo_web/live/page_live.html.heex` 1346 | to use the [`link`](https://hexdocs.pm/phoenix_live_view/Phoenix.Component.html#link/1) 1347 | component. This component allows `LiveView` to manage the navigation without having 1348 | to reload the page: 1349 | 1350 | ```html 1351 | <.link patch={Routes.live_path(@socket, LiveViewTodoWeb.PageLive, %{filter_by: "all"})}>All 1352 | <.link patch={Routes.live_path(@socket, LiveViewTodoWeb.PageLive, %{filter_by: "active"})}>Active 1353 | <.link patch={Routes.live_path(@socket, LiveViewTodoWeb.PageLive, %{filter_by: "completed"})}>Completed 1354 | ``` 1355 | 1356 | The `filter_by` query parameters can have the "all", "active" or "completed" value. 1357 | 1358 | We then define a new `handle_params` function in `lib/live_view_todo_web/live/page_live.ex`: 1359 | 1360 | ```elixir 1361 | @impl true 1362 | def handle_params(params, _url, socket) do 1363 | items = Item.list_items() 1364 | 1365 | case params["filter_by"] do 1366 | "completed" -> 1367 | completed = Enum.filter(items, &(&1.status == 1)) 1368 | {:noreply, assign(socket, items: completed, tab: "completed")} 1369 | 1370 | "active" -> 1371 | active = Enum.filter(items, &(&1.status == 0)) 1372 | {:noreply, assign(socket, items: active, tab: "active")} 1373 | 1374 | _ -> 1375 | {:noreply, assign(socket, items: items, tab: "all")} 1376 | end 1377 | end 1378 | ``` 1379 | 1380 | `live_patch` links will call this function to handle the navigation. 1381 | The `filter_by` value is checked and the list of `items` is filtered. 1382 | The socket is then updated using `assign` with the filter list. 1383 | 1384 | Finally we can add a test to make sure only the correct `items` are displayed. 1385 | In `test/live_view_todo_web/live/page_live_test.exs` add: 1386 | 1387 | ```elixir 1388 | test "Filter item", %{conn: conn} do 1389 | {:ok, item1} = Item.create_item(%{"text" => "Learn Elixir"}) 1390 | {:ok, _item2} = Item.create_item(%{"text" => "Learn Phoenix"}) 1391 | 1392 | {:ok, view, _html} = live(conn, "/") 1393 | assert render_click(view, :toggle, %{"id" => item1.id, "value" => 1}) =~ "completed" 1394 | 1395 | # list only completed items 1396 | {:ok, view, _html} = live(conn, "/?filter_by=completed") 1397 | assert render(view) =~ "Learn Elixir" 1398 | refute render(view) =~ "Learn Phoenix" 1399 | 1400 | # list only active items 1401 | {:ok, view, _html} = live(conn, "/?filter_by=active") 1402 | refute render(view) =~ "Learn Elixir" 1403 | assert render(view) =~ "Learn Phoenix" 1404 | 1405 | # list all items 1406 | {:ok, view, _html} = live(conn, "/?filter_by=all") 1407 | assert render(view) =~ "Learn Elixir" 1408 | assert render(view) =~ "Learn Phoenix" 1409 | end 1410 | ``` 1411 | 1412 | Two items are created and one is marked as completed. 1413 | The view is then rendered multiple times to verify the `filter_by` param 1414 | display the correct item 1415 | 1416 | Borrow from: 1417 | https://github.com/dwyl/phoenix-todo-list-tutorial#9-footer-navigation 1418 | 1419 |
1420 | 1421 | ## 10. Clear Completed 1422 | 1423 | To clear completed items the liveview needs to udpate all items with a status 1424 | defined as 1 to 2. 1425 | 1426 | First we update the "clear completd" button to use the `phx-click` binding to 1427 | create a new event, in `lib/live_view_todo_web/live/page_live.html.heex` update 1428 | the button to: 1429 | 1430 | ```html 1431 | 1432 | ``` 1433 | 1434 | In `lib/live_view_todo_web/live/page_live.ex` when then define a new `handle_event` function: 1435 | 1436 | ```elixir 1437 | @impl true 1438 | def handle_event("clear-completed", _data, socket) do 1439 | Item.clear_completed() 1440 | items = Item.list_items() 1441 | {:noreply, assign(socket, items: items)} 1442 | end 1443 | ``` 1444 | 1445 | In `lib/live_view_todo/item.ex` we update the list_items function: 1446 | 1447 | ```elixir 1448 | def list_items do 1449 | Item 1450 | |> order_by(desc: :inserted_at) 1451 | |> where([a], is_nil(a.status) or a.status != 2) 1452 | |> Repo.all() 1453 | end 1454 | ``` 1455 | 1456 | 1457 | Finally we need to define `Item.clear_completed/0` function in `lib/live_view_todo/item.ex`: 1458 | 1459 | ```elixir 1460 | def clear_completed() do 1461 | completed_items = from(i in Item, where: i.status == 1) 1462 | Repo.update_all(completed_items, set: [status: 2]) 1463 | end 1464 | ``` 1465 | 1466 | We can also add the following test to make sure completed items are removed: 1467 | 1468 | ```elixir 1469 | test "clear completed items", %{conn: conn} do 1470 | {:ok, item1} = Item.create_item(%{"text" => "Learn Elixir"}) 1471 | {:ok, _item2} = Item.create_item(%{"text" => "Learn Phoenix"}) 1472 | 1473 | # complete item1 1474 | {:ok, view, _html} = live(conn, "/") 1475 | assert render(view) =~ "Learn Elixir" 1476 | assert render(view) =~ "Learn Phoenix" 1477 | 1478 | assert render_click(view, :toggle, %{"id" => item1.id, "value" => 1}) 1479 | 1480 | view = render_click(view, "clear-completed", %{}) 1481 | assert view =~ "Learn Phoenix" 1482 | refute view =~ "Learn Elixir" 1483 | end 1484 | ``` 1485 | 1486 | 1487 | Borrow from: 1488 | https://github.com/dwyl/phoenix-todo-list-tutorial#10-clear-completed 1489 | 1490 | 1491 | ## 11. Live Components 1492 | 1493 | LiveView provides the Live Components feature to group UI state and events. 1494 | In this section we're going to see how to use component for items. 1495 | 1496 | The first step is to create a new file: 1497 | `lib/live_view_todo_web/live/item_component.ex` 1498 | 1499 | With the following code: 1500 | 1501 | ```elixir 1502 | defmodule LiveViewTodoWeb.ItemComponent do 1503 | use LiveViewTodoWeb, :live_component 1504 | alias LiveViewTodo.Item 1505 | 1506 | attr(:items, :list, default: []) 1507 | 1508 | def render(assigns) do 1509 | ~H""" 1510 |
    1511 | <%= for item <- @items do %> 1512 | <%= if item.id == @editing do %> 1513 | 1514 | 1523 | 1524 | 1525 | <% else %> 1526 |
  • 1527 |
    1528 | 1537 | 1545 | 1553 |
    1554 |
    • 1555 | <% end %> 1556 | <% end %> 1557 |
1558 | """ 1559 | end 1560 | end 1561 | ``` 1562 | 1563 | We have defined the `render` function which display the list of items. 1564 | Note that we have also defined the `attr` function. This tells us that we need 1565 | to pass the `:items` attribute when calling our component. 1566 | 1567 | In `lib/live_view_todo_web/live/page_live.html.heex` we can already call our component: 1568 | 1569 | ```heex 1570 |
1571 | 1572 | 1573 | <.live_component 1574 | module={LiveViewTodoWeb.ItemComponent} 1575 | id="cpn" 1576 | items={@items} 1577 | editing={@editing} 1578 | /> 1579 |
1580 | ``` 1581 | 1582 | Now that we have moved the `ul` and `li` tags to the render function we can 1583 | directly use `<.live_component/>`.
