This repository contains compatibility data for Web technologies. Browser compatibility data describes which platforms (where "platforms" are usually, but not always, web browsers) support particular Web APIs.
This data can be used in documentation, to build compatibility tables listing browser support for APIs. For example: Browser support for WebExtension APIs.
Maintained by the MDN team at Mozilla.
You can install mdn-browser-compat-data as a node package (tutorial).
npm install mdn-browser-compat-data
const bcd = require('mdn-browser-compat-data'); bcd.css.properties.background; // returns a compat data object (see schema)
Please note that we have not (yet) migrated all compatibility data from the MDN wiki pages into this repository.
Please note that we do not (yet) guarantee the stability of the data format. You're welcome to use the data, but its structure is subject to change without notice.
If you find a problem, please file a bug.
