Installation
npm install @superbalist/js-pubsub-redis

'use strict';

let RedisPubSubAdapter = require('@superbalist/js-pubsub-redis');
let client = redis.createClient({
host: 'redis',
port: 6379
});
let adapter = new RedisPubSubAdapter(client);
// consume messages
// note: this is a blocking call
adapter.subscribe('my_channel', (message) => {
console.log(message);
console.log(typeof message);
});
// publish messages
adapter.publish('my_channel', {first_name: 'Matthew'});
adapter.publish('my_channel', 'Hello World');
// publish multiple messages
let messages = [
'message 1',
'message 2',
];
adapter.publishBatch('my_channel', messages);
Examples
The library comes with examples for the adapter and a Dockerfile for running the example scripts.
Run make up
.
You will start at a bash
prompt in the /usr/src/app
directory.
If you need another shell to publish a message to a blocking consumer, you can run docker-compose run js-pubsub-redis /bin/bash
To run the examples:
$ node examples/RedisConsumerExample.js
$ node examples/RedisPublishExample.js (in a separate shell)
