Cloudflare Workers - Workflow

Generally, Cloudflare Workers can be written locally, deployed with serverless, and tested with the serverless invoke command. However, using the Cloudflare Workers Playground can help you test and view your worker’s results live if you need more insight while developing your Cloudflare Worker.

Below is a list of general tips for developing Cloudflare Workers with Serverless.

Development Workflow

Write your functions Use serverless deploy only when you've made changes to serverless.yml and in CI/CD systems. Use serverless deploy -f myFunction to rapidly deploy changes when you are working on a specific Cloudflare Workers Function. Use serverless invoke -f myFunction to test your Cloudflare Workers Functions.

Larger Projects

  • For Non-Enterprise Cloudflare customers, combining multiple workers into one file or using webpack.
  • Keep the Functions and Resources in your Serverless Services to a minimum.

Cheat Sheet

A handy list of commands to use when developing with the Serverless Framework.

Create A Service:

Creates a new Service:

serverless create -p [SERVICE NAME] -t cloudflare-workers
Deploy All

Use this when you have made changes to your Functions, Events or Resources in serverless.yml or you simply want to deploy all changes within your Service at the same time.

serverless deploy
Deploy Function

Use this to quickly overwrite your Cloudflare Workers Functions, allowing you to develop faster if you have an Enterprise account that supports deploying multiple functions.

serverless deploy -f [FUNCTION NAME]
Invoke Function

Invokes a Cloudflare Workers Function.

serverless invoke -f [FUNCTION NAME]
