CommonJS CommonJS — require() works on every Node.js version we test

picomatch ships CommonJS only. require("picomatch") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=12. import "picomatch" 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("picomatch") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=12.
  2. From ES modules use the default import: import picomatch from "picomatch"; then destructure. Named imports only work when Node.js can statically detect the exports.
  3. TypeScript: npm install -D @types/picomatch
