Sample Functions

Functions are blocks of code that run on demand without the need to manage any infrastructure. Develop on your local machine, test your code from the command line (using doctl), then deploy to App Platform — no servers required. Learn more about functions.


These repositories contain sample functions that you can deploy as components to App Platform. Each repository contains the necessary app-spec.yaml for App Platform and the requisite project structure, including project.yml.
