ESM-only ESM-only since 4.0.0 — last CommonJS version is 3.0.0

redent dropped its CommonJS build in 4.0.0 (May 2021). The last version with a plain require()-able CommonJS entry is 3.0.0, published Apr 26, 2019; it declares support for Node.js >=8.

On Node.js 20.19+, 22.12+ and newer, require("redent") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. On Node.js 18, which has no require(esm), require("redent") fails with ERR_REQUIRE_ESM.

What to do

  1. On Node.js 20.19+, 22.12+ and newer, require("redent") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
  2. From a CommonJS file, use a dynamic import inside an async function: const redent = await import("redent"). That works on every Node.js version the package supports (>=12).
  3. If you need a synchronous require() or run Node.js 18: npm install redent@3.0.0, the last CommonJS release (published Apr 26, 2019); it declares Node.js >=8.
  4. TypeScript: npm install -D @types/redent

How to import redent

ES modules (import)

import * as redent from "redent";

Namespace import shown because the ESM entry may have no default export; use named imports for what it exports.

CommonJS (require)

// Node.js 20.19+, 22.12+ and newer (verified):
const redent = require("redent");

// Any Node.js version the package supports (>=12), from an async function:
async function main() {
  const redent = await import("redent");
}

// Or pin the last CommonJS release (declares Node.js >=8):
// npm install redent@3.0.0

Module format by version
