@betit/orion-node-sdk

Installation

$ npm install @betit/orion-node-sdk

Basic example

Note - You will need to have running all of the orion dependencies

Add the following into foo.js and then run node foo.js --verbose

const ORION = require('@betit/orion-node-sdk');
const FOO = new ORION.Service('foo');

FOO.handle('get', (req, reply) => {
  reply(new ORION.Response('foo'));
});

FOO.listen(() => FOO.logger.createMessage('ready').send());

Then add the following into bar.js and then run node bar.js

const ORION = require('@betit/orion-node-sdk');
const BAR = new ORION.Service('bar');

const REQ = new ORION.Request('/foo/get');
BAR.call(REQ, res => {
  // do stuff
});

You can find more detailed examples in the examples folder.

Async example

This utility also supports functionality with Promises, so the following code can be also used:

const ORION = require('@betit/orion-node-sdk');
const FOO = new ORION.Service('foo');

FOO.handle('get', async (req) => {
  return new ORION.Response('foo');
});

async function initFOO() {
  await FOO.listen();
  FOO.logger.createMessage('ready').send()
}

init().then(exit);

And in bar.js:

const ORION = require('@betit/orion-node-sdk');
const BAR = new ORION.Service('bar');

const REQ = new ORION.Request('/foo/get');

async function main() {
  const res = await BAR.call(REQ);
  // do stuff
}

main().then(exit);

Also, subscriptions can now be looped forever using:

const ORION = require('@betit/orion-node-sdk');
const BAR = new ORION.Service('bar');

async function processEvents() {
  const producer = BAR.onAsync("event");

  while (true) {
    const event = await producer.consume();
  }
}
