Detect Changes Action Template

Generates a REUSABLE GitHub composite action that detects which domains have changed. Supports both Nx dependency graph analysis and path-based change detection.

Purpose​

This action is configuration-driven and accepts domain definitions as JSON input, making it truly reusable across any project without regeneration:

  • For Nx monorepos: Uses nx show projects --affected to leverage the dependency graph
  • For path-based projects: Uses path filters to detect which domains changed
  • Automatically falls back to path-based detection if Nx is unavailable

Key Design Principle​

Domains are passed as input, not hardcoded in the action. This allows the same action to work with any domain configuration without regeneration.

Generated Action Location​

actions/detect-changes/action.yml

Functions​

generate()​

function generate(ctx): Promise<any>;

Defined in: templates/actions/detect-changes.yml.tpl.ts:340

Generator entry point for detect-changes composite action.

Generates the actions/detect-changes/action.yml file with configuration-driven change detection logic. This action accepts domain configuration as input at runtime, making it truly reusable without regeneration.

Important: This action no longer embeds domain configurations. Instead, it receives them as JSON input from the workflow, allowing the same action to work with any domain configuration.

Parameters​

ctx​

PinionContext & object

Pinion generator context (domains no longer needed in template)

Returns​

Promise<any>

Updated context after file generation
