Last verified Sep 9, 2026 against wrap-ansi@10.0.1.

wrap-ansi dropped its CommonJS build in 8.0.0 (April 2021). The last version with a plain require()-able CommonJS entry is 7.0.0, published Apr 22, 2020; it declares support for Node.js >=10.

On Node.js 20.19+, 22.12+ and newer, require("wrap-ansi") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. Node.js 18 has no require(esm), and wrap-ansi@10.0.1 declares Node.js >=20, so 18 is outside its supported range anyway.

wrap-ansi@10.0.1 declares engines ">=20", so Node.js 18 is outside its supported range regardless of module format.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("wrap-ansi") 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 wrapAnsi = await import("wrap-ansi"). That works on every Node.js version the package supports (>=20).
3. If you need a synchronous require() or run Node.js 18: npm install wrap-ansi@7.0.0, the last CommonJS release (published Apr 22, 2020); it declares Node.js >=10.
4. wrap-ansi@10.0.1 declares engines ">=20", so Node.js 18 is unsupported regardless: upgrade Node.js or pin an older release.
5. TypeScript: types are bundled; install nothing extra.

```js
import * as wrapAnsi from "wrap-ansi";
```

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

CommonJS:

```js
// Node.js 20.19+, 22.12+ and newer (verified):
const wrapAnsi = require("wrap-ansi");

// Any Node.js version the package supports (>=20), from an async function:
async function main() {
  const wrapAnsi = await import("wrap-ansi");
}

// Or pin the last CommonJS release (declares Node.js >=10):
// npm install wrap-ansi@7.0.0
```
