# Is ejs ESM-only? Can you require() it?

> ejs@6.0.1 ships CommonJS and ESM builds. Dual package — require() works on every Node.js version we test; import works too.

Embedded JavaScript templates

Last verified Sep 9, 2026 against ejs@6.0.1.

ejs publishes both a CommonJS entry and a native ESM entry (ESM added in 4.0.1). require("ejs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.12.18. import "ejs" works alongside it.

## What to do

1. Nothing to change. require("ejs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.12.18. import * as ejs from "ejs" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: npm install -D @types/ejs

## How to import ejs

ES modules:

import * as ejs from "ejs";
```

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

```js
const ejs = require("ejs");
```
