For now, we recommend experimenting with Server Components via this demo app. **Use this in your projects at your own risk.** 26 | 27 | ## Should I use this demo for benchmarks? 28 | 29 | If you use this demo to compare React Server Components to the framework of your choice, keep this in mind: 30 | 31 | * **This demo doesn’t have server rendering.** Server Components are a separate (but complementary) technology from Server Rendering (SSR). Server Components let you run some of your components purely on the server. SSR, on the other hand, lets you generate HTML before any JavaScript loads. This demo *only* shows Server Components, and not SSR. Because it doesn't have SSR, the initial page load in this demo has a client-server network waterfall, and **will be much slower than any SSR framework**. However, Server Components are meant to be integrated together with SSR, and they *will* be in a future release. 32 | * **This demo doesn’t have an efficient bundling strategy.** When you use Server Components, a bundler plugin will automatically split the client JS bundle. However, the way it's currently being split is not necessarily optimal. We are investigating more efficient ways to split the bundles, but they are out of scope of this demo. 33 | * **This demo doesn’t have partial refetching.** Currently, when you click on different “notes”, the entire app shell is refetched from the server. However, that’s not ideal: for example, it’s unnecessary to refetch the sidebar content if all that changed is the inner content of the right pane. Partial refetching is an [open area of research](https://github.com/reactjs/rfcs/blob/main/text/0188-server-components.md#open-areas-of-research) and we don’t yet know how exactly it will work. 34 | 35 | This demo is provided “as is” to show the parts that are ready for experimentation. It is not intended to reflect the performance characteristics of a real app driven by a future stable release of Server Components. 36 | 37 | ## Setup 38 | 39 | You will need to have [Node 18 LTS](https://nodejs.org/en) in order to run this demo. (If you use `nvm`, run `nvm i` before running `npm install` to install the recommended Node version.) 40 | 41 | ``` 42 | npm install --legacy-peer-deps 43 | npm start 44 | ``` 45 | 46 | (Or `npm run start:prod` for a production build.) 47 | 48 | Then open http://localhost:4000. 49 | 50 | The app won't work until you set up the database, as described below. 51 | 52 |
53 | Setup with Docker (optional) 54 |

You can also start dev build of the app by using docker-compose.

55 |

⚠️ This is completely optional, and is only for people who prefer Docker to global installs!

56 |

If you prefer Docker, make sure you have docker and docker-compose installed then run:

57 | 
docker-compose up
58 |

Running seed script

59 |

1. Run containers in the detached mode

60 | 
docker-compose up -d
61 |

2. Run seed script

62 | 
docker-compose exec notes-app npm run seed
63 |

If you'd rather not use Docker, skip this section and continue below.

64 |
65 | 66 | ## DB Setup 67 | 68 | This demo uses Postgres. First, follow its [installation link](https://wiki.postgresql.org/wiki/Detailed_installation_guides) for your platform. 69 | 70 | Alternatively, you can check out this [fork](https://github.com/pomber/server-components-demo/) which will let you run the demo app without needing a database. However, you won't be able to execute SQL queries (but fetch should still work). There is also [another fork](https://github.com/prisma/server-components-demo) that uses Prisma with SQLite, so it doesn't require additional setup. 71 | 72 | The below example will set up the database for this app, assuming that you have a UNIX-like platform: 73 | 74 | ### Step 1. Create the Database 75 | 76 | ``` 77 | psql postgres 78 | 79 | CREATE DATABASE notesapi; 80 | CREATE ROLE notesadmin WITH LOGIN PASSWORD 'password'; 81 | ALTER ROLE notesadmin WITH SUPERUSER; 82 | ALTER DATABASE notesapi OWNER TO notesadmin; 83 | \q 84 | ``` 85 | 86 | ### Step 2. Connect to the Database 87 | 88 | ``` 89 | psql -d postgres -U notesadmin; 90 | 91 | \c notesapi 92 | 93 | DROP TABLE IF EXISTS notes; 94 | CREATE TABLE notes ( 95 | id SERIAL PRIMARY KEY, 96 | created_at TIMESTAMP NOT NULL, 97 | updated_at TIMESTAMP NOT NULL, 98 | title TEXT, 99 | body TEXT 100 | ); 101 | 102 | \q 103 | ``` 104 | 105 | ### Step 3. Run the seed script 106 | 107 | Finally, run `npm run seed` to populate some data. 108 | 109 | And you're done! 110 | 111 | ## Notes about this app 112 | 113 | The demo is a note-taking app called **React Notes**. It consists of a few major parts: 114 | 115 | - It uses a Webpack plugin (not defined in this repo) that allows us to only include client components in build artifacts 116 | - An Express server that: 117 | - Serves API endpoints used in the app 118 | - Renders Server Components into a special format that we can read on the client 119 | - A React app containing Server and Client components used to build React Notes 120 | 121 | This demo is built on top of our Webpack plugin, but this is not how we envision using Server Components when they are stable. They are intended to be used in a framework that supports server rendering — for example, in Next.js. This is an early demo -- the real integration will be developed in the coming months. Learn more in the [announcement post](https://reactjs.org/server-components). 122 | 123 | ### Interesting things to try 124 | 125 | - Expand note(s) by hovering over the note in the sidebar, and clicking the expand/collapse toggle. Next, create or delete a note. What happens to the expanded notes? 126 | - Change a note's title while editing, and notice how editing an existing item animates in the sidebar. What happens if you edit a note in the middle of the list? 127 | - Search for any title. With the search text still in the search input, create a new note with a title matching the search text. What happens? 128 | - Search while on Slow 3G, observe the inline loading indicator. 129 | - Switch between two notes back and forth. Observe we don't send new responses next time we switch them again. 130 | - Uncomment the `await fetch('http://localhost:4000/sleep/....')` call in `Note.js` or `NoteList.js` to introduce an artificial delay and trigger Suspense. 131 | - If you only uncomment it in `Note.js`, you'll see the fallback every time you open a note. 132 | - If you only uncomment it in `NoteList.js`, you'll see the list fallback on first page load. 133 | - If you uncomment it in both, it won't be very interesting because we have nothing new to show until they both respond. 134 | - Add a new Server Component and place it above the search bar in `App.js`. Import `db` from `db.js` and use `await db.query()` from it to get the number of notes. Oberserve what happens when you add or delete a note. 135 | 136 | You can watch a [recorded walkthrough of all these demo points here](https://youtu.be/La4agIEgoNg?t=600) with timestamps. (**Note:** this recording is slightly outdated because the repository has been updated to match the [latest conventions](https://react.dev/blog/2023/03/22/react-labs-what-we-have-been-working-on-march-2023#react-server-components).) 137 | 138 | ## Built by (A-Z) 139 | 140 | - [Andrew Clark](https://twitter.com/acdlite) 141 | - [Dan Abramov](https://twitter.com/dan_abramov) 142 | - [Joe Savona](https://twitter.com/en_JS) 143 | - [Lauren Tan](https://twitter.com/sugarpirate_) 144 | - [Sebastian Markbåge](https://twitter.com/sebmarkbage) 145 | - [Tate Strickland](http://www.tatestrickland.com/) (Design) 146 | 147 | ## [Code of Conduct](https://engineering.fb.com/codeofconduct/) 148 | Facebook has adopted a Code of Conduct that we expect project participants to adhere to.
