Lightning Web Components Recipes Open Source

A collection of easy-to-digest code examples for Lightning Web Components Open Source. Each recipe demonstrates how to code a specific task in 30 lines of code or less. A View Source link takes you right to the code in GitHub. From Hello World to data access and third-party libraries, there is a recipe for that!

Modifications for Edge browser users

The Edge browser currently doesn't support native shadow DOM. If you want to use this application you have to manually add the synthetic shadow DOM to your clone. Add to the first line of the index.js this code:

import '@lwc/synthetic-shadow';

Code Tours

Code Tours are guided walkthroughs that will help you understand the app code better. To be able to run them, install the CodeTour VSCode extension.
