The skeleton of your code’s house 🏗️
A framework is a pre-built structure that provides a foundation for developing software applications. Instead of starting from scratch, developers use frameworks to speed up development by relying on a set of tools, libraries, and best practices that solve common problems and enforce consistency.
It’s like building with LEGO blocks—you still get to be creative, but the pieces are already shaped for you.
What does a Framework do?
A framework provides:
- Predefined architecture: It lays out how your application should be organized.
- Reusable components: Offers ready-to-use code for common tasks like routing, form handling, or database access.
- Inversion of control: Rather than calling the framework, the framework calls your code at the right time (also known as the “Hollywood Principle”: Don’t call us, we’ll call you).
Examples of Popular Frameworks
- Web: Django (Python), Ruby on Rails (Ruby), Laravel (PHP), ASP.NET (C#)
- Frontend: React (JS library but often used as a framework), Angular, Vue.js
- Mobile: Flutter, React Native
- Machine Learning: TensorFlow, PyTorch
Why Use a Framework?
- Faster development: Cut down time with pre-built components.
- Better security: Most frameworks handle security best practices for you.
- Scalability: Frameworks are designed to grow with your project.
- Community support: Well-known frameworks come with documentation and large user communities.
Frameworks aren’t just shortcuts—they’re battle-tested blueprints for building reliable, scalable, and maintainable software.
