Action Functions - bettyblocks/cli Wiki


Functions are snippets of code that can be published to the Actions IDE so that they can be used as ActionSteps in Actions. We currently only support functions written in Javascript.

Action Functions can be initialised, validated and published using the bb functions namespace of the CLI.

Each Action Function consists of two parts.

  1. The implementation of the function itself, written in Javascript.
  2. The function definition, describing the workings in a JSON format following a predefined JSON Schema.

This wiki contains information on how to create new functions and then validate and publish them.

Getting started

  1. To get started with Action Functions, make sure you first install the CLI.

  2. After you've installed the CLI, hop over to the documentation to find out how to create a new Functions project. Check out these examples on how to define your Function.

  3. Once you're done defining and implementing your function, you're ready to publish.


For an application called my-own-app

$ npm install -g @betty-blocks/cli
$ bb functions init my-own-app --app
$ cd my-own-app
$ bb functions new hello-world
$ bb functions publish
