# Lambda function
Discover the Lambda function preset with Nitro to deploy Nuxt to any lambda-compatible serverless platform.
::alert{icon=IconPresets}
Back to [presets list](/docs/deployment/presets).

## Usage
2021-11-21 12:31:44 +00:00
You can use the [Nuxt config](/docs/directory-structure/nuxt.config) to explicitly set the preset to use:
```ts [nuxt.config.js|ts]
export default {
nitro: {
preset: 'lambda'
}
}
```
Or directly use the `NITRO_PRESET` environment variable when running `nuxt build`:
```bash
NITRO_PRESET=lambda npx nuxt build
```
### Entrypoint
2021-11-21 12:31:44 +00:00
When running `nuxt build` with the Lambda preset, the result will be an entry point that exports a handler function that responds to an event and returns a response.
2021-11-21 12:31:44 +00:00
This entry point is compatible with [AWS Lambda](https://docs.aws.amazon.com/lex/latest/dg/lambda-input-response-format.html) and [Netlify Functions](https://docs.netlify.com/functions/build-with-javascript).

It can be used programmatically or as part of a deployment.
```ts
import { handler } from './.output/server'
// Use programmatically
const { statusCode, headers, body } = handler({ path: '/' })
```
