3h-room

A simple lib for SSE room management.

Example

Here's an example SSE room server based on express:

const express = require('express');
const SSE = require('3h-sse');
const HR = require('3h-room');

const app = express();

const createSSEController = () =>
    new SSE.SSEController({
        backend: new SSE.NodeJSBackend(),
    })

const room = new HR.Room({
    maxMemberCount: 2,
    sseController: createSSEController(),
});

room.on('enter', (member) => {
    member.sendEvent('info', 'welcome');
})

app.get('/sub/:name', (req, res) => {

    const member = new HR.Member({
        identity: decodeURIComponent(req.params.name),
        response: res,
        sseController: createSSEController(),
    });

    member.on('enter', (_room) => {
        _room.sendEvent('debug', 'member entered: ' + member.identity);
    });
    member.on('leave', (_room) => {
        _room.sendEvent('debug', 'member left: ' + member.identity);
    });

    try {
        room.addMember(member);
    } catch (error) {
        res.status(403);
        res.end();
        return;
    }

    res.once('close', () => {
        room.removeMember(member);
    });

});

app.listen(8080);
