Compatibility tables data

This repository contains the raw data served by the WebPlatform project at docs.webplatform.org/compat/data.json.

To learn more about how the data is used, refer to WebPlatform Docs Infrastructure CompaTables Component

To use

Under a GNU/Linux or MacOS, you can use it as a NPM module.

Install

There’s nothing much to install to contribute. The package.json will make you install underscore-cli that can be (optionally) used to query and validate the JSON file.

npm install

Change data

Edit the data-human.json following the same format, commit and make a pull request.

Checking data

You can use the awesome underscore-cli to query and validate the JSON from the command line.
