About The Project

The helyosjs-sdk helps the development of javascript applications using the helyOS framework. This library contains all necessary methods and entity types to build a front-end using helyOS as backend system.

List of features

• Log in as administrator or regular user.
• List and edit automatons (agents).
• Retrieve sensors data and work process status.
• Create, schedule and handle work processes.
• Manage and edit yards: set drivable areas, gates, obstacles, etc.

Built With

• Typescript
• Apollo
• Socket.io

Getting Started

Installation

$ npm i helyosjs-sdk  --save

Usage

import { HelyosServices, H_Agents  } from 'helyosjs-sdk';

const helyosService = new HelyosServices('http://localhost', {socketPort:'5002', gqlPort:'5000'});

const username = 'admin@email.com';
const password = 'password';

 helyosService.login(username, password)
.then( response => helyosService.connect())
.then( connected => console.log(connected));;

function listAgents(conditions={}) {
    return helyosService.agents.list(conditions)
    .then((agents: H_Agent[]) => {
        console.log(agents);
    });
}

function editTool(patch: H_Agents) {
    return helyosService.agents.patch(patch)
    .then(agents => {
        console.log(agents);
    )}
}

Listening agent/agent sensors and work process status

helyosService.connect()
.then(() => {
            const socket = helyosService.socket;

            socket.on('new_agent_poses',(updates)=>{
                console.log(updates);  // Notifications from agent sensors.
            });

            socket.on('change_agent_status',(updates)=>{
                console.log(updates);  // Notifications from agents working status.
            });

            socket.on('change_work_processes',(updates)=>{
                console.log(updates);  // Notifications from work processes status.
            });
});
