Magento 2 DevTools

An extension for Google Chrome (and likely Mozilla Firefox) that exposes helpful debugging utilities for Magento 2 front-ends.

Early Release

This is a very new project with little to no documentation, published to solicit feedback from early adopters. The extension is currently only available through manual installation of the development build, and will be published to the Chrome Web Store at a future time.

Documentation

Usage

Whenever you navigate to a page running Magento 2, a new tab should appear in DevTools from this extension.

In-Progress Features

• RequireJS Optimizer configuration generator (including Magento module for quick install)
• RequireJS module registry inspector

Possible Future Features

• uiComponents Explorer/Inspector (think React/Angular DevTools)
• m2 Front-End best-practices checks

Running Development Build (Google Chrome)

Prerequisites

• node.js >= 8.x
• npm >= 6.x

Setup

1. Clone the repository
2. Run npm install
3. Run npm start
4. Navigate to chrome://extensions
5. Enable Developer mode
6. Click Load unpacked
7. Select the extension folder in the root of this repository

Notes

• To run a single build, use npm run build instead of npm start
• If you have Chrome DevTools open when you make a change in src, you'll need to close and re-open DevTools to see the changes
• If you need to debug the DevTools page (React app in src), open the Magento 2 tab in DevTools, then right click + Inspect Element. This will open a new instance of the DevTools pointed at the React application.
