#Cloudflare Workers - Functions

If you are using Cloudflare as a provider, all functions inside the service are Cloudflare Workers.

#Configuration

All of the Cloudflare Workers in your serverless service can be found in serverless.yml under the functions property.

# serverless.yml

service:
  name: hello-world

provider:
  name: cloudflare
  config:
    accountId: CLOUDFLARE_ACCOUNT_ID
    zoneId: CLOUDFLARE_ZONE_ID

plugins:
  - serverless-cloudflare-workers

functions:
  helloWorld:
    # What the script will be called on Cloudflare (this property value must match the function name one line above)
    name: helloWorld
    # The name of the script on your machine, omitting the .js file extension
    script: helloWorld
    # Events are only relevant to the `serverless invoke` command and don’t affect deployment in any way
    events:
      - http:
          url: example.com/hello/*
          method: GET
          headers:
            someKey: someValue

The script property points to the file containing your Cloudflare Worker.

// helloWorld.js

addEventListener('fetch', event => {
  event.respondWith(handleRequest(event.request));
});

async function handleRequest(request) {
  return new Response('Hello world');
}

If you have an Enterprise Cloudflare account, you can add multiple Cloudflare Workers to your project.

# serverless.yml

service:
  name: hello-world

provider:
  name: cloudflare
  config:
    accountId: CLOUDFLARE_ACCOUNT_ID
    zoneId: CLOUDFLARE_ZONE_ID

plugins:
  - serverless-cloudflare-workers

functions:
  helloWorld:
    # What the script will be called on Cloudflare (this property value must match the function name one line above)
    name: helloWorld
    # The name of the script on your machine, omitting the .js file extension
    script: helloWorld
    # Events are only relevant to the `serverless invoke` command and don’t affect deployment in any way
    events:
      - http:
          url: example.com/hello/*
          method: GET
          headers:
            someKey: someValue

  # Only Enterprise accounts would be allowed to add this second function and its corresponding route above
  foo:
    name: foo
    script: bar
    events:
      - http:
          url: example.com/foo/*
          method: GET

The script property is what the Cloudflare Worker will be called on Cloudflare’s data centers.
