Part 1 — Create the Dependency Preparation Job

Tasks

1. Create the Workflow file:

.github/workflows/ci.yml

1. Configure Workflow triggers:
   • push on all branches
   • pull_request
2. Create a Job named prepare-dependencies
3. Configure the Job to run on ubuntu-latest
4. Add a checkout step using actions/checkout@v4
5. Add a Cache step using actions/cache@v4
6. Give the Cache step an id named node-modules-cache
7. Configure the Cache step:
   • path: node_modules
   • key: using:
     • runner.os
     • hashFiles('**/package-lock.json')
   • restore-keys: using a prefix match
8. Add an installation step running:

npm ci

1. Add an if: condition to the installation step:
   • Use:

steps.node-modules-cache.outputs.cache-hit

- Understand the condition:
    - If Cache Hit = `true`
    - Skip `npm ci`
    - If Cache Miss = run `npm ci`

11. Push the Workflow and inspect the logs:

• First push should show:

Cache not found for key...
