🌌 Darkroom Cloud Application

This project is a cloud-deployed photo gallery built with
Node.js, Express, MongoDB, and EJS.
It supports cloud deployment pipelines, testing, and CI/CD integrations with Jenkins, Render, and Slack.

---

🚀 Milestone 1: Set Up

• Forked and cloned the starter repo.
• Configured MongoDB Atlas cluster and created a database user.

---

🔧 Milestone 2: Basic Pipeline

• Created a Jenkinsfile for automated CI/CD.
• Pipeline installs dependencies (npm install), builds, and deploys to Render.
• Configured auto-trigger on push events.
• Updated landing page with “MILESTONE 2” text, deployed live.

🧪 Milestone 3: Tests

• Discovered tests on the test branch → merged into main.
• Updated Jenkinsfile to run npm test before deploying.
• Configured Jenkins email notifications if tests fail.
• Updated landing page to display:
  • “MILESTONE 2”
  • “MILESTONE 3”

---

💬 Milestone 4: Slack Integration

• Created a Slack channel.
• Jenkins → Slack integration.
• Notifications with build ID + Render link.

🔧 Recent Fixes

• MongoDB Authentication Issue → updated Atlas URI to encode password (@ → %40).
• Config Debugging → ensured process.env.NODE_ENV is set correctly on Render, added logging in server.js.
• Deployment → automated via Jenkins pipeline.

Update 1

🔐 MongoDB Configuration & Security

To keep the MongoDB credentials safe and out of the public repo, I moved all sensitive connection strings into a secret environment variable instead of hardcoding them into the _config.js file.

Originally, the _config.js contained direct connection URLs for development, production, and test environments. These have now been replaced with a hidden variable that Render manages securely.

⚙️ How It Works

• The app checks for a value in process.env.MONGO_URI_PRODUCTION.
  If it’s set (for example, when deployed on Render), it connects using that URI.

• If no environment variable is found, it falls back to the values defined in _config.js for local testing and development.

  const mongoURI = process.env.MONGO_URI_PRODUCTION || config.mongoURI[env];
  

🌍 Deployment

✅ On successful build, app is deployed to Render:
