API for Space Cloud FaaS Engines

Installation

$ npm install space-engine-node --save

Quick Start

Create Engine Instance

const Engine = require('space-engine-node');

const engine = new Engine('my-engine');

Note: All instances with same engine name are automatically load balanced.

Register the function

engine.registerFunc('my-func', (params, auth, cb) => {
console.log('Params:', params, 'Auth', auth)
// Do something

const res = { ack: true, message: 'Function as a Service is Awesome!' }
cb('response', res)
})

Note: Enable Functions module in Space Cloud, run space-exec and nats server to be able to use it.
