CPPWebFramework
1.0.0
C++ Web Framework (CWF) adalah kerangka web MVC, Open Source, di bawah Lisensi MIT, menggunakan C++ dengan Qt untuk digunakan dalam pengembangan aplikasi web. CWF dirancang untuk menggunakan sedikit sumber daya komputasi, seperti memori dan pemrosesan, serta memiliki waktu respons yang rendah untuk permintaan. Dengan arsitektur MVC (Model-View-Controller), di mana Anda dapat membuat kelas untuk menangani lapisan bisnis (Model), gunakan CSTL (C++ Server Pages Standard Tag Library) di dalam Halaman Web untuk menangani presentasi data (View) dan gunakan pengontrol sebagai penghubung antara dua lapisan (Pengontrol). CWF mendapat inspirasi dalam Java Servlets, JSTL dan Spring Framework.
Karena dibuat di Qt, C++ Web Framework dapat berjalan di platform yang sama yang didukung oleh Qt:
CWF hanya memiliki satu file konfigurasi, yang disebut CPPWeb.ini dan kebijakan hanya menggunakan C++ dan Qt dalam pengembangan komponennya untuk menghindari instalasi banyak perpustakaan dan konflik, mempertahankan karakteristik multiplatform, memfasilitasi instalasi dan menjaga kurva pembelajaran rendah untuk membuat pengembangan web sesederhana mungkin, bahkan untuk pemula.
