Last verified Sep 9, 2026 against tslint-config-prettier@1.18.0.

tslint-config-prettier ships CommonJS only. require("tslint-config-prettier") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=4.0.0. import "tslint-config-prettier" 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("tslint-config-prettier") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=4.0.0.
2. From ES modules use the default import: import tslintConfigPrettier from "tslint-config-prettier"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for tslint-config-prettier; declare the module yourself if you need them.
