JavaScript and TypeScript utilities for [Netlify Functions](https://docs.netlify.com/functions/overview/).

## Installation

```

npm install @netlify/functions

```

## Usage

### On-demand Builders

To use On-demand Builders, wrap your function handler with the `builder` function.

- With JavaScript:

  ```js

  const { builder } = require('@netlify/functions')

  const handler = async (event, context) => {

    return {

      statusCode: 200,

      body: JSON.stringify({ message: 'Hello World' }),

    }

  }

  exports.handler = builder(handler)

  ```

- With TypeScript:

  ```ts

  import { builder, Handler } from '@netlify/functions'

  const myHandler: Handler = async (event, context) => {

    return {

      statusCode: 200,

      body: JSON.stringify({ message: 'Hello World' }),

    }

  }

  const handler = builder(myHandler)

  export { handler }

  ```

### Scheduled Functions (currently in beta)

To use Scheduled Functions, wrap your function handler with the `schedule` function.

- With JavaScript:

  ```js

  const { schedule } = require('@netlify/functions')

  exports.handler = schedule('5 4 * * *', async () => {

    console.log("It's 04:05 AM!")

  })

  ```

- With TypeScript:

  ```ts

  import { schedule } from '@netlify/functions'

  export const handler = schedule("5 4 * * *", async () => {

    console.log("It's 04:05 AM!")

  })

  ```

### TypeScript typings

This module exports typings for authoring Netlify Functions in TypeScript.

```ts

import { Handler } from '@netlify/functions'

const handler: Handler = async (event, context) => {

  return {

    statusCode: 200,

    body: JSON.stringify({ message: 'Hello World' }),

  }

}

export { handler }

```

The following types are exported:

- `Handler`

- `HandlerCallback`

- `HandlerContext`

- `HandlerEvent`

- `HandlerResponse`
