Middy logo

CORS middleware for the middy framework, the stylish Node.js middleware engine for AWS Lambda

This middleware sets CORS headers (Access-Control-Allow-Origin, Access-Control-Allow-Headers, Access-Control-Allow-Credentials), necessary for making cross-origin requests, to the response object.

Sets headers in after and onError phases.

Install

To install this middleware you can use NPM:

npm install --save @middy/cors

Options

  • origin (string) (optional): origin to put in the header (default: "*")
  • headers (string) (optional): value to put in Access-Control-Allow-Headers (default: null)
  • credentials (bool) (optional): if true, sets the Access-Control-Allow-Origin as request header Origin, if present (default false)

Sample usage

const middy = require('middy')
const { cors } = require('middy/middlewares')
 
const handler = middy((event, context, cb) => {
  cb(null, {})
})
 
handler.use(cors())
 
// when Lambda runs the handler...
handler({}, {}, (_, response) => {
  expect(response.headers['Access-Control-Allow-Origin']).toEqual('*')
})
