Lightning SDK

This SDK allows you to build Lightning-based apps. It contains Lightning and a Mediaplayer and other specific utitilies for app development.


First, create a new directory to develop your app in.

Add a new package.json for your project:

  "author": "Metrological",
  "name": "your-app",
  "version": "1.0.0"

Run npm i --save

Your application is expected to be in src/App.js, and it must extend ux.App:

class MyApp extends ux.App {


Add an index.html file. Import the DevLauncher from the SDK, and use it to launch your application for development purposes. Example index.html:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8" />
<script type="module">
    import DevLauncher from "./node_modules/wpe-lightning-sdk/DevLauncher.js";
    import App from "./src/App.js";

    const launcher = new DevLauncher();
    launcher.launch(App, {debug: true}, {useInspector: false})


Releasing your app can be done using a couple of scripts in this package. It may be handy to include these as shorthands in your app's package.json file:

"scripts": {
    "release-web": "node ./node_modules/wpe-lightning-sdk/scripts/release-web.js",
    "release-mpkg": "node ./node_modules/wpe-lightning-sdk/scripts/release-mpkg.js",
    "upload-app": "node ./node_modules/wpe-lightning-sdk/scripts/upload-app-metrological.js"

Standalone web version

Run the scripts/release-web.js script from your application directory. It will create the dist/web folder that includes your bundled app and a set of files that allow running it on ES6 and ES5 supporting browsers. Simply place it on a web server and navigate to the index.html file and it should work.

Metrological package.

Run the scripts/release-mpkg.js script from your application directory. It expects a metadata.json file containing configuration specific to the Metrological framework.

Metrological upload.

Run the scripts/upload-app-metrological.js script from your application directory, this will run the package script as stated above and upload the package to the Metrological dashboard. You need to provide an Api key as argument: npm run upload-app *api-key*


Check Lightning-examples for an example of a working application development setup using this SDK.

You can’t perform that action at this time.
