bcryptjs: Used for hashing user passwords before storing them in the database. cors: Used to enable Cross-Origin Resource Sharing (CORS). dotenv: Used to load environment variables from a .env file. express: Used as the web framework for the app. jsonwebtoken: Used to create and verify JSON Web Tokens (JWTs) for user authentication. mongoose: Used as an Object Data Modeling (ODM) library for MongoDB.
Development Dependencies The app also uses several development dependencies:
@babel/cli, @babel/core, @babel/node, and @babel/preset-env: Used to transpile modern JavaScript code into a version that can be run by older Node.js versions. eslint-config-prettier and eslint-plugin-prettier: Used to integrate Prettier with ESLint for code formatting. nodemon: Used to automatically restart the server when changes are made during development.
