# CI/CD Pipeline – GitHub Actions → Docker Hub (Node.js)

Build a CI/CD pipeline using **GitHub Actions** that builds a Docker image for a **Node.js** app and pushes it to **Docker Hub** automatically on every push to `main`.

---

## What this pipeline does

- Checks out your repo

- Installs Node.js and dependencies

- Runs tests (optional but recommended)

- Builds a Docker image

- Pushes the image to **Docker Hub** with tags:

- `latest`

- `git-sha` (immutable version)
