Deploy a Full-Stack Realtime App in seconds using Serverless Components . Just provide your frontend code (powered by the website component ), and your backend code (powered by the socket component ).
Some great use-cases for this project are: Chat Apps, Bots, Notification systems, Charting Dashboards, Stock Tickers and more. As always, consider a serverless stack like this if you are looking to deliver software or features with incredibly low overhead.
1. Install
$ npm install -g @serverless/components
2. Create
$ mkdir my-realtime-app && cd my-realtime-app
the directory should look something like this:
|- backend |- socket.js |- frontend |- index.html |- serverless.yml
the socket.js
file should minimally look something like this:
on('default', async (data, socket) => { socket.send(data) })
For more info on working with the socket.js
file, check out the socket component docs .
To see a full example of an application built with this, check out this Chat Application .
3. Configure
# serverless.yml name: my-realtime-app stage: dev RealtimeApp: component: "@serverless/realtime-app" inputs: name: my-realtime-app description: My Realtime App region: us-east-1 # backend config to be passed to the socket component backend: # path to the backend code that contains the socket.js file code: ./backend memory: 512 timeout: 10 env: TABLE_NAME: users # frontend config to be passed to the website component frontend: # path to the directory that contains your frontend code # if you're using a framework like React, that would be the root of your frontend project, otherwise it'd be where index.html lives. # default is './frontend' code: ./static # if your website needs to be built (e.g. using React)... # default is "undefined" build: # the path to the build directory. default is ./build dir: ./dist # the build command command: npm run build # this is the default anyway! # you can provide an env file path (relative to the code path above) to be generated for use by your frontend code. By default it's './src/env.js' envFile: ./frontend/src/env.js # the contents of this env file # the backend api url will be injected by default # under the "urlWebsocketApi" key env: SOME_API_URL: https://api.com
