 1 | # Simple Serverless Real-Time API (WebSockets)<br/> with AWS AppSync 
 2 | ### (No GraphQL knowledge required)
 3 | <br/>
 4 | This is an implementation of a simple real-time API based on WebSockets where clients are subscribed to a specific channel and any JSON data can be pushed automatically to clients listening/subscribed to the channel. Clients define the channel they're subscribed to and there can be as many channels as required. Connections, scalability, fan-out and broadcasting are all automatically handled by the API.
 5 | <br/>
 6 | <br/>
 7 | 
 8 | The GraphQL API is defined in code where a GraphQL schema and API definition is generated [programatically](https://docs.aws.amazon.com/cdk/api/latest/docs/aws-appsync-readme.html#code-first-schema). Client code is also automatically generated. Hand coding GraphQL schema, queries, mutations, subscriptions is not required. If there's no need to leverage the built-in GraphQL strongly typed system, this pattern allows to send any data to connected/subscribed clients as long as it's in a valid JSON format.
 9 | <br/>
10 | <br/>
11 | 
12 | ## Requirements
13 | 
14 | * [Create an AWS account](https://portal.aws.amazon.com/gp/aws/developer/registration/index.html) if you do not already have one and log in. The IAM user that you use must have sufficient permissions to make necessary AWS service calls and manage AWS resources.
15 | * [Git installed](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
16 | * [Node and NPM](https://nodejs.org/en/download/) installed
17 | * [AWS Cloud Development Kit](https://docs.aws.amazon.com/cdk/latest/guide/cli.html) (AWS CDK) installed
18 | * [Amplify CLI](https://docs.amplify.aws/cli/start/install/), only required to generate code as the backend deployment is done via AWS CDK
19 | <br/>
20 | <br/>
21 | 
22 | ## Deploy the API to the cloud
23 | 
24 | 1. Clone the project to your local working directory:
25 | 
26 |    ```sh
27 |    git clone https://github.com/awsed/simpleWSAPI
28 |    ```
29 | 
30 | 2. Change the working directory to:
31 | 
32 |    ```sh
33 |    cd simpleWSAPI/cdk
34 |    ```
35 | 
36 | 3. Install the project dependencies:
37 | 
38 |    ```sh
39 |    npm install
40 |    ```
41 | 
42 | 4. Deploy the stack to your default AWS account and region. After deployment, the output of this command shows the GraphQL API endpoint, API ID, and API key. Take note of all the details as they'll be needed to setup the client:
43 | 
44 |    ```sh
45 |    cdk deploy
46 |    ```
47 | <br/>
48 | <br/> 
49 | 
50 | ## Configure the React.js client
51 | 
52 | 1. Change the working directory to the `client` folder:
53 | 
54 |    ```sh
55 |    cd ../client
56 |    ```
57 | 
58 | 2. Install the project dependencies:
59 | 
60 |    ```sh
61 |    npm install
62 |    ```
63 | 3. Open the file `src/App.js` and update the [AppSync API congifuration details](https://github.com/awsed/simpleWSAPI/blob/68bc0846dc2edb5e13a75767a060153e37ceeaee/client/src/App.js#L9) based on the output of the previous `cdk deploy`.
64 | 
65 | 4. Define a [name for your channel](https://github.com/awsed/simpleWSAPI/blob/68bc0846dc2edb5e13a75767a060153e37ceeaee/client/src/App.js#L22), as an optional step.
66 | 
67 | 5. Generate the necessary code to interact with the API using the [Amplify CodeGen](https://docs.amplify.aws/cli/graphql-transformer/codegen/) with the API ID output of the previous `cdk deploy`. There's no need to create an Amplify CLI project, however you'll need to download the API schema from the [AWS Appsync Console](https://console.aws.amazon.com/appsync/home). Select the API `WS-API` in your account and, in the Schema section, select **Export schema**. Download and copy the schema file to the root of the `/client` folder, where you need to execute the following command accepting all defaults:
68 | 
69 |    ```sh
70 |    amplify add codegen --apiId xxxxxxxxxxxxxxxxxxxxxx
71 |    ```
72 | 
73 | 6. Execute the application and access it from multiple browser tabs/windows at http://localhost:3000 :
74 | 
75 |     ```bash
76 |     npm start
77 |     ```
78 | 
79 | 7. Send any valid JSON payload from one client and get it broadcasted in all browser windows. Since AWS AppSync automatically scales to demand, you can have thousands of clients broadcasting JSON data. You can also have multiple [channels](https://github.com/awsed/simpleWSAPI/blob/68bc0846dc2edb5e13a75767a060153e37ceeaee/client/src/App.js#L22) defined in different instances of the clients and confirm only clients subscribed to specific channels receive the JSON data.

 1 | # Getting Started with Create React App
 2 | 
 3 | This project was bootstrapped with [Create React App](https://github.com/facebook/create-react-app).
 4 | 
 5 | ## Available Scripts
 6 | 
 7 | In the project directory, you can run:
 8 | 
 9 | ### `yarn start`
10 | 
11 | Runs the app in the development mode.\
12 | Open [http://localhost:3000](http://localhost:3000) to view it in the browser.
13 | 
14 | The page will reload if you make edits.\
15 | You will also see any lint errors in the console.
16 | 
17 | ### `yarn test`
18 | 
19 | Launches the test runner in the interactive watch mode.\
20 | See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
21 | 
22 | ### `yarn build`
23 | 
24 | Builds the app for production to the `build` folder.\
25 | It correctly bundles React in production mode and optimizes the build for the best performance.
26 | 
27 | The build is minified and the filenames include the hashes.\
28 | Your app is ready to be deployed!
29 | 
30 | See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
31 | 
32 | ### `yarn eject`
33 | 
34 | **Note: this is a one-way operation. Once you `eject`, you can’t go back!**
35 | 
36 | If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
37 | 
38 | Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
39 | 
40 | You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
41 | 
42 | ## Learn More
43 | 
44 | You can learn more in the [Create React App documentation](https://facebook.github.io/create-react-app/docs/getting-started).
45 | 
46 | To learn React, check out the [React documentation](https://reactjs.org/).
