#Cloudflare Workers - HTTP Events

The only type of event that is supported in Cloudflare Workers is HTTP events, so defining events in your serverless.yml is optional. Defined events in your serverless.yml are only used by the serverless invoke command, which can be useful for testing your Functions.

#Serverless Yml

When creating a service your serverless yml will define which endpoint is used for your function when you run the serverless invoke command.

# serverless.yml
...
functions:
  helloWorld:
    # What the script will be called on Cloudflare
    worker: hello
    # The name of the script on your machine, omitting the .js file extension
    script: helloWorld
    events:
      - http:
          url: example.com/hello/user
          method: GET
          headers:
            greeting: hi

The events section in the yml above makes it so that the Function helloWorld will be used for request to the example.com/hello/user endpoint. This configuration would send a GET request with a header called greeting that has a value of hi to the example.com/hello/user endpoint when you run serverless invoke -f helloWorld.
