Last verified Sep 9, 2026 against parseurl@1.3.3.

parseurl ships CommonJS only. require("parseurl") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 0.8. import "parseurl" 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("parseurl") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 0.8.
2. From ES modules use the default import: import parseurl from "parseurl"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/parseurl
