Package Exports

mdn-browser-compat-data

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mdn-browser-compat-data) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

browser-compat-data

https://github.com/mdn/browser-compat-data

Maintained by the MDN team at Mozilla.

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 JavaScript APIs.

Repository contents

There's a top-level directory for each broad area covered: for example, "http", "javascript", "webextensions". Inside each of these directories is one or more JSON files containing the compatibility data.

api

css

Contains experimental data for CSS.

http

Contains experimental data for HTTP.

javascript

webextensions

Format of the browser compat json files

The definitive description of the format used to represent compatibility data is the schema file. But since the schema is hard to read, we have created a human-readable description of it.

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.

Problems?

If you find a problem, please file a bug.

We're very happy to accept contributions to this data. Please familiarize yourself with the schema and send us a pull request.
