How can I use conditional executions in GitHub Actions?

You can use the if conditional to control when a job or step runs in GitHub Actions. For example, you can specify conditions based on the result of previous jobs or the value of environment variables.

Can you give me an example of using the if condition?

Sure! Here's a simple example:

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Run tests
        run: npm test
      - name: Deploy
        if: success()  # This step runs only if the previous step was successful
        run: ./deploy.sh

What other conditions can I use with if?

You can use various contexts and expressions, such as github.event_name, github.ref, or even custom environment variables. For example, you can check if the event is a pull request or if a specific branch is being pushed.

Is there a way to combine multiple conditions?

Yes, you can combine conditions using logical operators like && (AND) and || (OR). For example:

if: github.event_name == 'push' && github.ref == 'refs/heads/main'
