Back-End Development: The Engine That Powers Websites
While front-end is what users see, back-end development powers what happens behind the scenes. It handles data, business logic, and security.
Core elements include:
- Programming Languages: Node.js, Python, PHP, Java, Ruby.
- Databases: SQL (MySQL, PostgreSQL) and NoSQL (MongoDB, Firebase).
- Servers: Apache, Nginx, Express.js.
- Authentication & Security: JWT, OAuth, password hashing.
- APIs: REST and GraphQL for communication.
For example, when a user logs into Facebook:
- The front-end displays the login form.
- The back-end checks the credentials against a database.
-If correct, it returns data and keeps the user logged in securely.
Back-end ensures websites are dynamic, secure, and scalable.
