Implementation of the hyperswarm API for use in web browsers
npm i -s hyperswarm-web
// Based on example in hyperswarm repo
// Try running the regular hyperswarm demo with node
const hyperswarm = require('hyperswarm-web')
const crypto = require('crypto')
const swarm = hyperswarm({
// If you omit this, it'll try to connect to 'wss://hyperswarm.mauve.moe'
// It will also attempt to connect to a local proxy on `ws://localhost:4977`
wsProxy: 'ws://yourproxy.com'
})
// look for peers listed under this topic
const topic = crypto.createHash('sha256')
.update('my-hyperswarm-topic')
.digest()
swarm.join(topic)
swarm.on('connection', (socket, details) => {
console.log('new connection!', details)
// you can now use the socket as a stream, eg:
// socket.pipe(hypercore.replicate()).pipe(socket)
})Build it with Browserify to get it running on the web.
You could also compile an existing codebase relying on hyperswarm to run on the web by adding a browser field set to {"hyperswarm": "hyperswarm-web"} to have Browserify alias it when compiling dependencies.
npm i -g hyperswarm-web
# Run it! Default port is 4977 (HYPR on a phone pad)
hyperswarm-web
# Run it with a custom port
hyperswarm-web --port 42069

# Check that hyperswarm-web is present at this location
# If it's not, replace the path with its location
# You can get the location with 'whereis hyperswarm-web'
# Optionally add a --port parameter if you don't want 4977
