A smaller version of caniuse-db, with only the essentials!

Last verified Sep 9, 2026 against caniuse-lite@1.0.30001810.

caniuse-lite ships CommonJS only. require("caniuse-lite") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "caniuse-lite" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("caniuse-lite") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import caniuseLite from "caniuse-lite"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/caniuse-lite
