title: ESM
---
## ESM Support
As of v8.15.x node-postgres supporters the __ECMAScript Module__ (ESM) format. This means you can use `import` statements instead of `require` or `import pg from 'pg'`.
CommonJS modules are still supported. The ESM format is an opt-in feature and will not affect existing codebases that use CommonJS.
The docs have been changed to show ESM usage, but in a CommonJS context you can still use the same code, you just need to change the import format.
If you're using CommonJS, you can use the following code to import the `pg` module:
```js
const pg = require('pg')
const { Client } = pg
// etc...
```
### ESM Usage
If you're using ESM, you can use the following code to import the `pg` module:
```js
import { Client } from 'pg'
// etc...
```
Previously if you were using ESM you would have to use the following code:
```js
import pg from 'pg'
const { Client } = pg
// etc...
```
