Pluggable microservice framework
npm install @betit/orion[![Build Status][travis-image]][travis-url] [![Coverage Status][codecov-image]][codecov-url] [![NPM Version][npm-image]][npm-url]
Orion is a pluggable framework for microservices.
Following "batteries included but removable" design philosophy. Providing sane default implementations, but everything is swappable. Comes with built in support for various transports and codecs.
- Async communication: event driven architecture (pub/sub)
- Sync communication: request-response transport layer
- RPC: clean and simple interface to build services
- Transport: provides an interface for sync request/response communication
- Codec: used for encoding and decoding messages before transporting across the wire
- Service: provides an interface to name your service and register request handlers
- Client: provides an interface to make requests to services
- Transports: NATS _(default)_
- Codecs: JSON _(default)_, MessagePack
Service:
``javascript
const orion = require('@betit/orion');
const service = new orion.Service('calc');
service.handle('add', (req, reply) => {
reply(null, parseInt(req.params.a) + parseInt(req.params.b));
});
service.listen(() => {
console.log(Service started: ${service});`
});
Client:
`javascript
const orion = require('@betit/orion');
const client = new orion.Client({ service: 'calc' });
client.call('add', { a: 3, b: 2 }, (err, res) => {
console.log(err, res);
client.close();
});
