Basic Usage

Quick Setup on the Server Side

export default fp<FastifyRabbitMQOptions>((fastify, options, done) => {

   void fastify.register(fastifyRabbit, {
      connection: `amqp://guest:guest@localhost`
   })

   void fastify.ready().then(async () => {

     const snowAssignAssetTag = fastify.rabbitmq.createConsumer({
       queue: 'foo',
       queueOptions: {durable: true}
     }, async (msg: any) => {
        console.log(msg) // ==> bar
     })
      
   })
  
});

Quick Setup on the Client Side

Within any "endpoint" function, or if you have access to fastify.rabbitmq you can then call:

fastify.get('/rabbitmq', async (request, reply) => {
   let pub = request.rabbitmq.createPublisher({
      confirm: true,
      maxAttempts: 1
   })

   await pub.send('foo', "bar") // ==> sent to foo queue
})

Sending the string bar to the queue called foo.

Connection String or object pointing to the RabbitMQ Broker Services. This can be an object of ConnectionOptions from the rabbitmq-client plugin options.

namespace
