Cylon.js (http://cylonjs.com) is a JavaScript framework for robotics, physical computing, and the Internet of Things (IoT).
API plugins are separate from the Cylon.js main module, to allow for greater modularization of Cylon robots.
This repository contains the Cylon API plugin for HTTP.
For more information about Cylon, check out the repo at https://github.com/hybridgroup/cylon
$ npm install cylon cylon-api-http
With both of these modules installed, you can make your robots accessible over HTTP:
"use strict";
var Cylon = require("cylon");
Cylon.api("http", {
ssl: false // serve unsecured, over HTTP
// optional configuration here.
// for details see 'Configuration' section.
});
Cylon.robot({
name: "Maria",
connections: {
arduino: { adaptor: 'firmata', port: '/dev/ttyACM0' }
},
devices: {
led: { driver: 'led', pin: 13 }
},
work: function() {
// we'll interact with this robot through the API
}
}).start();
Once you've got a Cylon instance with the API configured and running, you can use cURL to test it out:
$ curl http://127.0.0.1:4000/api/robots/Maria
{ "robot": { "name": "Maria" /* ... */ } }
This plugin follows the CPPP-IO specification.
To get started, you can visit the /api
route in your browser to get an overview of the Cylon Master Control Program (MCP).
This provides a high level overview of your program:
$ curl http://127.0.0.1:4000/api | python -m json.tool
{
"MCP": {
"commands": [ ],
"events": [ ],
"robots": [
{
"name": "Maria",
"connections": [
{
"name": "arduino",
"adaptor": "firmata",
"details": { "port": "/dev/ttyACM0" }
}
],
"devices": [
{
"name": "led",
"commands": [ "toggle" ],
"connection": "arduino",
"details": { "pin": "13" },
"driver": "LED"
}
],
"commands": [ ],
"events": [ ]
}
]
}
}
For details on other available routes in the API and expected responses, please see the [specification document][spec].
This plugin includes a default front-end in Robeaux.
Robeaux is a simple tool to use against the HTTP API, and explore your robots visually, while also able to issue commands to robots and listen for events.
