Rabbitode is a probject created to provide a simple interface in order to work with the AMQP interface to rabbitmq. RabbitMQ is an events broker that allows us to send a recieve events between producers and consumers via an event queue.
- Installation via npm
npm install rabbitode -S - Installation via yarn
yarn add rabbitode
In order for this project to run you must have a working instance of rabbitmq on your machine or server.
I reccomend docker for local development.
docker run -p 5672:5672 -d --rm --name rabbit rabbitmq:3

});- Most methods return this to enable method chaining
- send method no longer available, use sendDirect, sendTopic, sendFanout instead
- Security Vulnerability fixes in package.json
- Security Vulnerability fixes in package.json
- Update build process for smaller files
- Total refactor to functional components
- Reduced methods single method for send / consume
- Able to be imported as individual files or as a main rabbitode file
- Total removal of original Rabbitode class
- Added tests to ensure methods call as required
- More indepth types and logging
