Example Workflow

name: Collect API environment variables

on:
  push:
    branches: [main]

jobs:
  collect-env:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Collect API environment variables
        uses: dev-five-git/collect-env-action@main
        with:
          prefix: 'API_'
          output: '.env.api'
          remove-prefix: true
          secrets: ${{ toJson(secrets) }}

Example

If you have the following environment variables:

• API_KEY=secret123
• API_URL=https://api.example.com
• API_TIMEOUT=5000
• DATABASE_URL=postgres://localhost

And you run the action with:

• prefix: 'API_'
• remove-prefix: true

The output file will contain:

KEY=secret123
URL=https://api.example.com
TIMEOUT=5000

If remove-prefix: false, the output will be:

API_KEY=secret123
API_URL=https://api.example.com
API_TIMEOUT=5000
