Path Filtering

Skip workflows when relevant files haven't changed.

Native GitHub Feature

Path filtering is built into GitHub Actions. No custom code required—just configure paths and paths-ignore in your workflow triggers.

Native GitHub Feature

GitHub Actions provides built-in path filtering:

on:
  push:
    paths:
      - 'src/**'
      - 'package.json'
    paths-ignore:
      - '**.md'
      - 'docs/**'

This is a platform feature, not a pattern implementation. See the official documentation for full syntax.

When to Use

• Monorepo builds - Only build changed packages
• Documentation changes - Skip CI for doc-only PRs
• Config changes - Trigger only relevant pipelines
