ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@mdn/browser-compat-data
Advanced tools
@mdn/browser-compat-data is a comprehensive dataset that provides browser compatibility information for various web technologies, including HTML, CSS, JavaScript, and more. It is maintained by MDN Web Docs and is useful for developers who need to know which features are supported by different browsers.
Check CSS property support
This feature allows you to check the browser compatibility of a specific CSS property. In this example, it checks the compatibility of the 'border-radius' property.
const bcd = require('@mdn/browser-compat-data');
const css = bcd.css.properties;
console.log(css['border-radius']);
Check JavaScript API support
This feature allows you to check the browser compatibility of a specific JavaScript API. In this example, it checks the compatibility of the 'Promise' API.
const bcd = require('@mdn/browser-compat-data');
const js = bcd.javascript.builtins;
console.log(js['Promise']);
Check HTML element support
This feature allows you to check the browser compatibility of a specific HTML element. In this example, it checks the compatibility of the 'video' element.
const bcd = require('@mdn/browser-compat-data');
const html = bcd.html.elements;
console.log(html['video']);
caniuse-lite is a smaller, more compact version of the data from caniuse.com. It provides browser support tables for various web technologies. Compared to @mdn/browser-compat-data, caniuse-lite is more lightweight and focuses on providing quick access to compatibility data.
browserslist is a tool that allows you to specify which browsers you want to support in your project. It uses data from caniuse-lite to determine browser compatibility. While @mdn/browser-compat-data provides detailed compatibility information, browserslist helps you configure your project to support specific browsers.

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.

You can install @mdn/browser-compat-data
as a node package.
npm install @mdn/browser-compat-data
const bcd = require('@mdn/browser-compat-data');
bcd.css.properties.background;
// returns a compat data object (see schema)
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 file containing the compatibility data.
css/ contains data for CSS properties, selectors, and at-rules.
html/ contains data for HTML elements, attributes, and global attributes.
http/ contains data for HTTP headers, statuses, and methods.
javascript/ contains data for JavaScript built-in Objects, statement, operators, and other ECMAScript language features.
mathml/ contains data for MathML elements, attributes, and global attributes.
svg/ contains data for SVG elements, attributes, and global attributes.
webdriver/ contains data for WebDriver commands.
webextensions/ contains data for WebExtensions JavaScript APIs and manifest keys.
xslt/ contains data for XSLT elements, attributes, and global attributes.
The definitive description of the format used to represent compatibility data is the schema file. You can also have a look at the schema documentation.
