appcd-client

appcd-client

The Node.js client for connecting to the Appc Daemon. Internally appcd-client uses a WebSocket for communicating with the server.

Visit https://github.com/appcelerator/appc-daemon for more information.

Installation

npm i appcd-client

Usage

import Client from 'appcd-client';

const client = new Client();

client
	.request('/appcd/status')
	.on('response', status => {
		console.log(status);
		client.disconnect();
	})
	.on('error', err => {
		console.error('ERROR!');
		console.error(err);
	});

To subscribe to a service:

client
	.request({
		path: '/appcd/status/system/loadavg',
		type: 'subscribe'
	})
	.on('response', status => {
		console.log(status);
		client.disconnect();
	})
	.on('error', err => {
		console.error('ERROR!');
		console.error(err);
	});

Starting the Appc Daemon

request() will automatically call connect(), however it will error if the daemon is not running. You can call connect() prior to making your request and specify the startDaemon flag:

const client = new Client();

(async () => {
	try {
		// connect to the daemon and start it if its not running.
		await new Promise((resolve, reject) => {
			client
				.connect({ startDaemon: true })
				.on('connected', resolve)
				.on('error', reject);
		});

		await new Promise((resolve, reject) => {
			client
				.request('/appcd/status')
				.on('response', status => {
					console.log(status);
					client.disconnect();
					resolve();
				})
				.on('error', reject);
		});
	} catch (err) {
		console.error('ERROR!');
		console.error(err);
	}
})();
