Study Notes

Setting Up a Calendar Service Project

The mkdir calendar-service command creates a new directory named calendar-service, which will contain the project files.
The cd calendar-service command changes the current directory to calendar-service, meaning all subsequent commands will be executed within this directory.
The npm init -y command initializes a new Node.js project by creating a package.json file with default settings. The -y flag automatically agrees to all prompts, avoiding manual input.
The npm install express mysql2 sequelize cors command installs essential packages for the calendar service:
- Express: A web framework for Node.js used for building APIs and web applications.
- mysql2: A MySQL client for Node.js, enabling interaction with MySQL databases.
- sequelize: An ORM for Node.js simplifying database interaction by allowing JavaScript objects instead of raw SQL.
- cors: Middleware for Cross-Origin Resource Sharing (CORS), allowing the server to handle requests from different origins.
