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.

• 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

Example

import AstMetadata from 'ast-metadata-inferer';

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