# qewd-client: ES6 Module version of QEWD Client Rob Tweed 02 March 2020, M/Gateway Developments Ltd [http://www.mgateway.com](http://www.mgateway.com) Twitter: @rtweed Google Group for discussions, support, advice etc: [http://groups.google.co.uk/group/enterprise-web-developer-community](http://groups.google.co.uk/group/enterprise-web-developer-community) # About this Repository This repository contains an ES6 Module that provides the client functionality for QEWD Applications. # Using the QEWD Client This client is already installed in the official Docker versions of QEWD Server. Otherwise, use *git clone* to copy the module to your system. The QEWD Client is completely self-contained and loads its dependencies automatically. First, create an *app.js* file for your application, eg: import {QEWD} from './qewd-client.js'; // adjust the path for the qewd-client module depending on where you've saved it document.addEventListener('DOMContentLoaded', function() { QEWD.on('ewd-registered', function() { // Your QEWD environment is ready // optionally turn on logging to the console QEWD.log = true; // now you can begin sending QEWD messages, eg: QEWD.send({ type: 'hello world' }, function(responseObj) { console.log('response: ' + JSON.stringify(responseObj)); }); // etc }); // start the QEWD service and register your application QEWD.start({ application: 'hello-world' }); }); Then create an *index.html* file that loads your app.js module: Hello World Demo Make sure the QEWD back-end is running and load your *index.html* page into your browser, and it should all burst into life.
