npm install amqplib
A library for making AMQP 0-9-1 clients for Node.JS, and an AMQP 0-9-1 client for Node.JS v0.8, v0.9, v0.10, and v0.11.
Project status:
- Expected to work
- Complete high-level and low-level APIs (i.e., all bits of the protocol)
- A fair few tests
- Measured test coverage
- Ports of the RabbitMQ tutorials as examples
Still working on:
- Getting to 100% (or very close to 100%) test coverage
- Settling on completely stable APIs
- Establishing a long history of battle-testing in production (if anyone has been using it in production, do let me know)
var q = 'tasks';
var open = require('amqplib').connect('amqp://localhost');
// Publisher
open.then(function(conn) {
var ok = conn.createChannel();
ok = ok.then(function(ch) {
ch.assertQueue(q);
ch.sendToQueue(q, new Buffer('something to do'));
});
return ok;
}).then(null, console.warn);
// Consumer
open.then(function(conn) {
var ok = conn.createChannel();
ok = ok.then(function(ch) {
ch.assertQueue(q);
ch.consume(q, function(msg) {
if (msg !== null) {
console.log(msg.content.toString());
ch.ack(msg);
}
});
});
return ok;
}).then(null, console.warn);npm test
Best run with a locally-installed RabbitMQ, but you can point it at
another using the environment variable URL; e.g.,
URL=amqp://dev.rabbitmq.com npm test
NB You may experience test failures due to timeouts if using the dev.rabbitmq.com instance.
You can run it under different versions of Node.JS using nave:
nave use 0.8 npm test
or run the tests on all supported versions of Node.JS in one go:
make test-all-nodejs
(which also needs nave installed, of course).
Lastly, setting the environment variable LOG_ERRORS will cause the
tests to output error messages encountered, to the console; this is
really only useful for checking the kind and formatting of the errors.
LOG_ERRORS=true npm test
