JavaScript and TypeScript utilities for Netlify Functions.

Installation

npm install @netlify/functions

Usage

On-demand Builders

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

• With JavaScript:

  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:

  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:

  const { schedule } = require('@netlify/functions')
  
  exports.handler = schedule('5 4 * * *', async () => {
    console.log("It's 04:05 AM!")
  })

• With TypeScript:

  import { schedule } from '@netlify/functions'
  
  export const handler = schedule("5 4 * * *", async () => {
    console.log("It's 04:05 AM!")
  })
