ast-metadata-inferer

A collection of metadata about browser API's. This collection is intended for tools that analyze JS. It currently supports 3993 compatibility records.

For all the API's it supports, it gives the

AST node type of the API (MemberExpression, NewExpression, or CallExpression)
Determines if an API is statically invoked (ex. document.querySelector())
Determines if an API is a CSS or JS API
Provides compatibility information from mdn-browser-compat-data

Usage

import AstMetadata from 'ast-metadata-inferer';

const [firstRecord] = AstMetadata;
console.log(firstRecord);
// {
//   "language":"js-api",
//   "protoChain":["document","querySelector"],
//   "protoChainId":"document.querySelector",
//   "astNodeTypes":["MemberExpression"],
//   "isStatic":true,
//   "compat": {
//     support: {
//       chrome: {
//         version_added: "14"
//       },
//       chrome_android: { version_added: "18" },
//       ...
