Hello World Plus

Technology Chosen

  • Backend
    • Node.js
    • Express.js framework for routing and middleware
    • pg library for connecting to db
    • express-session and pg-simple-session for sessions
    • morgan for logging
    • nodemon for dev live reloading
    • dotenv for environmental variables
    • node-fetch for fetching the name-meaning website
    • cheerio for parsing the html returned
  • Database
    • PostgreSQL for users, name data, and sessions
  • Frontend
    • React.js

Note:

  • The reason I chose Node.js for the backend is because it is what I am most familiar with. Node stands out for async programming and heavy I/O uses cases like a real-time chat or gaming. This hello world plus app is just a simple CRUD app and so any back-end language would do.
