WebRocket is a framework for WebSockets, its purpose is to create an abstraction on top of WebSockets just like http servers are on top of TCP/IP servers.

WebRocket simplify WebSockets usage by creating a rest api like interface.

Client example project

Server example project

Client

yarn add @hetrodo/webrocket

const WebRocket = require('@hetrodo/webrocket/lib/WebRocket');
const WebRocketMethod = require('@hetrodo/webrocket/lib/WebRocketMethod');
const WebSocketAdapter = require('@hetrodo/webrocket/lib/WebSocketAdapter');

//First we connect to the WebSocket server
const ws = new WebSocket('ws://127.0.0.1:8080');

//We wait for the connection to open
ws.onopen = () => {
    //With the connection open we instantiate the WebRocket class
    const clientAdapter = new WebSocketAdapter(ws);
    const webRocket = new WebRocket(clientAdapter);

    //Now we can register the client-side endpoints that we want using GET, POST, PUT, DELETE methods.
    webRocket.on(WebRocketMethod.get, 'v1/client-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    webRocket.on(WebRocketMethod.post, 'v1/client-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    webRocket.on(WebRocketMethod.put, 'v1/client-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    webRocket.on(WebRocketMethod.delete, 'v1/client-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    //And using the WebRocket's class instance we can make requests to the server-side defined endpoints
    webRocket.get('v1/server-entity').then(console.log).catch(console.error);
    webRocket.post('v1/server-entity', {}).then(console.log).catch(console.error);
    webRocket.put('v1/server-entity', {}).then(console.log).catch(console.error);
    webRocket.delete('v1/server-entity').then(console.log).catch(console.error);

    //You can use query params too
    webRocket.get('v1/server-entity?key=value').then(console.log).catch(console.error);
};

Server

yarn add express ws @hetrodo/webrocket

const express = require('express');
const { createServer } = require('http');
const { WebSocketServer } = require('ws');
const WebRocket = require('@hetrodo/webrocket');
const WebRocketMethod = require('@hetrodo/webrocket/lib/WebRocketMethod');
const WebSocketAdapter = require('@hetrodo/webrocket/lib/WebSocketAdapter');

//Create your WebSocket server
const app = express();
const server = createServer(app);
const wss = new WebSocketServer({ server });

wss.on('connection', function (ws) {
    //When a connection established we can instantiate a new WebRocket.
    const webRocket = new WebRocket(new WebSocketAdapter(ws));

    //Now we can register the server-side endpoints that we want using GET, POST, PUT, DELETE methods.
    webRocket.on(WebRocketMethod.get, 'v1/server-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    webRocket.on(WebRocketMethod.post, 'v1/server-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    webRocket.on(WebRocketMethod.put, 'v1/server-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    webRocket.on(WebRocketMethod.delete, 'v1/server-entity', (request, respond) => {
        respond({
            msg: 'Ok'
        });
    });

    //And using the WebRocket's class instance we can make requests to the client-side defined endpoints
    webRocket.get('v1/client-entity').then(console.log).catch(console.error);
    webRocket.post('v1/client-entity', {}).then(console.log).catch(console.error);
    webRocket.put('v1/client-entity', {}).then(console.log).catch(console.error);
    webRocket.delete('v1/client-entity').then(console.log).catch(console.error);

    //Just like in the client side you can use query params too
    webRocket.get('v1/client-entity?key=value').then(console.log).catch(console.error);
});

server.listen(8080, function () {
    console.log('Listening on http://localhost:8080');
});
