Why should you care?

Express and Mongoose run on Node — a clean API project layout avoids mixing frontend build tools into the server.

See it live — copy this example

Paste into your MeanVerse project (Angular + Express + MongoDB), then run with ng serve / node / mongosh as noted.

mkdir meanverse-api && cd meanverse-api
npm init -y
npm install express mongoose dotenv
npm install -D typescript ts-node @types/node @types/express nodemon
// package.json scripts
"scripts": {
  "dev": "nodemon --exec ts-node src/server.ts",
  "start": "node dist/server.js"
}

What happened?

• npm init creates package.json.
• express and mongoose are runtime deps.
• ts-node runs TypeScript directly in dev.
• nodemon restarts on file changes.

Practice next

1. Install Node LTS from nodejs.org or nvm.
2. Create meanverse-api with npm init.
3. Add express, mongoose, dotenv.
4. Add "type": "module" and use import syntax.
5. Pin engines.node in package.json to your LTS version.

Remember

Node runs MeanVerse backend processes. package.json scripts document how to start dev vs prod. Match Node version with CI and Docker images.

E-commerce API bootstrap

MeanVerse shop needs a Node API before Black Friday traffic.

Outcome: Standard npm scripts let ops run the same start command in Docker.
