Build your own websocket event stream for Ethereum using Amberdata.io! Example code uses Amberdata's Websockets

Clone:

git clone git@github.com:amberdata/amberdata-example-websockets.git

1. Get API Key

Go to amberdata.io and click "Get started"

2. Build:

Building with Amberdata.io is as simple as a few a few lines of code:

// Create WebSocket connection.
const socket = new WebSocket('wss://ws.web3api.io?x-api-key=YOUR_API_KEY_HERE');

// Connection opened
socket.addEventListener('open', function (event) {
    console.log('Connection opened - ', event);
    socket.send(`{"jsonrpc":"2.0","id":0,"method":"subscribe","params":["block"]}`);
    socket.send(`{"jsonrpc":"2.0","id":1,"method":"subscribe","params":["uncle"]}`);
    socket.send(`{"jsonrpc":"2.0","id":2,"method":"subscribe","params":["transaction"]}`);
    socket.send(`{"jsonrpc":"2.0","id":3,"method":"subscribe","params":["function"]}`);
});

// Listen for messages
socket.addEventListener('message', responseHandler);
