Crystal: A C++ Framework

C++ Web Application Framework created from scratch. Inspired by Express and Django.

Motivation

In the beginning, it was a simple HTTP server built using sockets in C++, but it evolved into a flexible and minimal framework for building web applications.

My C++, DSA, and Networking skills were honed by developing this project and I gained a deep understanding of how servers operate.

• Dynamic Router
• URL Path Params and Query String Support
• Response Status Codes
• JSON Parser and Creator
• JSON Body Support in Requests and Responses
• Cookies Support
• Automatic Public File Indexing and Parsing
• Routing and Controller Structure Similar to Express
• Request Redirect
• HTML Page Support

Note

Currently, this project only runs on Linux, but I plan to add support for Windows and Mac in the future.
