Remitter

Description

Redis is awesome. But have you seen how one accomplishes pub/sub with the (otherwise incredibly awesome) redis module? Good ol' fashion event emitting/listening but using redis instead of node's native event emitter.

Redis

You need a redis instance. Configure it in your environment (replace host and port with your instance info)

$ export REDIS_URL=redis://127.0.0.1:6379/

Install

$ npm install remitter --save

Usage

  const Remitter = require('remitter');
  const thing = Remitter(process.env.REDIS_URL);

  thing
    .connect()
    .then(() => {
      thing.on('foo', (foo) => {
        console.log('foo'); // { beep: 'boop' }
      });
    });

    // .... elsewhere in your app - maybe even another process!
    const thing2 = Remitter(process.env.REDIS_URL);
    thing2
      .connect()
      .then(() => {
        thing2.emit('foo', { beep: 'boop' });
      });
  

  // ...some time later
  thing.destroy();
  thing1.destroy();

Test

$ echo "REDIS_URL=redis://127.0.0.1:6379/" >> test/test.env
$ npm test

Usage no npm install needed!
