What are GitHub workflows and how do they work?

GitHub workflows are automated processes that you can set up in your GitHub repository to build, test, and deploy your code. They are defined in YAML files and can be triggered by various events like pushes, pull requests, or on a schedule.

Can you give me an example of a simple workflow?

Sure! A simple workflow could be one that runs tests every time you push code to the main branch. It would look something like this in a YAML file:

name: CI
on: [push]
jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Run tests
        run: npm test

What are some common events that can trigger a workflow?

Common events include 'push', 'pull_request', 'release', and 'schedule'. You can also create custom events.

How can I debug a workflow if it fails?

You can check the Actions tab in your GitHub repository to see the logs for each step of the workflow. This will help you identify where it failed.
