Full-Stack Web Development with PERN Tech Stack: Postgres, Express, React and Node.

Deployment with Heroku

Important Notes covering summaries from Frontend to Backend and finally deploying to Heroku.

1. PostgreSQL: Postgres is a TCP Server listening on a TCP port ( 5432 by default) for request. It uses the postgres://protocol.

Chapter 52. Frontend/Backend Protocol

• psql is the PostgreSQL command line interface
• GUI like Postico, Datazenit
• Install PostGreSQL

2. Express: Express allows you to start and configure a server with very little overhead and instead focus on the important work of defining server behavior.

• create routes to implement server behavior for different HTTP methods and paths.
• routers and middleware, in order to write clean and readable server-side code
• Back — End Architecture

3. React JS: Javascript library for building user interfaces built by Facebook. React is fast and easier to build more modular and reusable code.

• React uses a special syntax called JSX.
• Thinking in React
• React Lifecycle Methods

4. Node JS: is a platform for building applications.

• Allows to run JavaScript outside of the browser.
• is server-side Javascript runtime built on Chrome’s V8 JS Engine
• Node.js’ npm largest ecosystem of open source libraries
