Last verified Sep 9, 2026 against esquery@1.7.0.

esquery ships CommonJS only. require("esquery") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.10. import "esquery" 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.

It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.

## What to do

1. require("esquery") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.10.
2. From ES modules use the default import: import esquery from "esquery"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/esquery
