A wrapper around fidm/quic, node-quic is a dead simple stream based QUIC server / client for use in node.js.
node-quic is a simple way to bring QUIC / UDP into your application.
npm install node-quicimport quic from 'node-quic'
const port = 1234
const address = '127.0.0.1' // default
quic.listen(port, address)
.then(() => {}) // called once server starts listening
.onError((error) => {}) // called if there's an error with the listening.
// There are three classes of error:
// * 'server error'
// * 'server session error'
// * 'server stream error'
// An error will come out as an object with key
// `class` containing one of the above. More information
// will be in the error object.
.onData(
(data, stream, buffer) => {}
) // data here will be a stringified version of
// whatever was sent using quic.send(), stream will have
// two function properties: `write` and `end.`
// Use stream.write(data) to return information to the
// original sender. Note: stream.write will automatically
// stringify any non-buffer data sent to it, but you will need
// to parse your own data on the way out of `.onData` for
// `quic.listen` and for `quic.send`. Use `stream.end()`
// if you don't need to send anything back. If you are working
// with buffers directly and don't need anything stringified,
// you can use the buffer argument.
quic.send(port, address, data) // Send data to a listening server. `data` is automatically
// stringified, but will need to be parsed manually on receive.
.then(() => {}) // called after the stream is written
.onError((error) => {}) // called on error. The error classes for `quic.send` are:
// * 'client stream error'
.onData((data, buffer) => {}) // `data` is populated by whatever the receiving server deems
// necessary to send back. `buffer` contains the unstringified
// version of the data.There are also a few utility functions:
quic.stopListening() // kill the server
quic.getServer() // return low level server object. Note, a server will only be
// returned following a call to `.listen()` and preceding any
// calls to `.stopListening()`, a.k.a. when quic is listening.
quic.getAddress() // returns an object {
// port: <number>,
// family: <string>, // like 'IPv4'
// address: <string> // defaults to '127.0.0.1'
// }
// Note: these fields will be 0 or the empty string if quic
// is not listening.For example:
const port = 1234
const address = '127.0.0.1'
// First we listen.
quic.listen(port, address)
.onData((data, stream, buffer) => {
const parsedData = JSON.parse(data)
console.log(parsedData) // { hello: 'world!' }
// Once the data is received and logged, we'll send it right back
stream.write(parsedData)
})
// Now we send the data to the server.
quic.send(port, address, { hello: 'world!' })
.onData(data => {
// This is the data that was sent right back
const parsedData = JSON.parse(data)
console.log(parsedData) // { hello: 'world!' }
// now we can stop the server from listening if we want this to be a one-off
quic.stopListening()
})Easy Peasy. Enjoy!
