Jackrabbitjs NPM

JackrabbitJS

JackrabbitJS is a amqplib wrapper built to hide the complexities of messaging protocols. It was built for smaller to midlevel projects that need a simple messaging api that works.

Usage

Installing JackrabbitJS

npm install jackrabbitjs --save

Consumer:

const jackrabbit = require('jackrabbitjs');

const credentials = {
    uri: 'server-uri',
    user: 'jack',
    password: 'rabbitjs'
};

let options = {
    queue: 't',
    ack: true
};

jackrabbit.connect(credentials, (err, connection) => {
    jackrabbit.consume(connection, options, (err, message) => {
        console.log(message.content.toString());
    });
});

Producer:

const jackrabbit = require('jackrabbitjs');

const credentials = {
    uri: 'server-uri',
    user: 'jack',
    password: 'rabbitjs'
};

let options = {
    queue: 't',
    payload: 'ello',
    timeout: 3000
};

jackrabbit.connect(credentials, (err, connection) => {
    if (err) {
        process.exit(1);
    }
    jackrabbit.produce(connection, options);
});

    queue: 't',
    rpc: true
};

jackrabbit.connect(credentials, (err, connection) => {
    jackrabbit.consume(connection, options, (e, message, channel) => {
        if(channel) {
            jackrabbit.reply(message.properties.replyTo, message.properties.correlationId, channel, 'jackrabbitjs');
        }
    });
});
