Crow framework features and specs

  • Lightweight
    Crow is a very lightweight web framework designed for C++ which makes it suitable for high-performance applications where resource efficiency is important.
  • Header-only
    Being a header-only library, Crow is easy to integrate into existing C++ projects without the need for complex build configurations or additional dependencies.
  • C++14 Support
    Crow requires C++14, which allows developers to use some modern C++ features that can help with writing more efficient and cleaner code.
  • Ease of Use
    The framework offers a simple and straightforward API that makes setting up HTTP routes and handling requests more convenient compared to other more complex alternatives.
  • Good for Prototyping
    Crow's simplicity and ease of setup make it a good choice for quickly prototyping web applications in C++.

Possible disadvantages of Crow framework

  • Limited Features
    Crow may not have as many built-in features as some more established frameworks, making it necessary to implement certain functionalities manually.
  • Community and Support
    The community around Crow is not as large as other more popular frameworks, which might limit the availability of community support and third-party resources.
  • Lack of Official Documentation
    Crow's documentation may not be as comprehensive or up-to-date as other frameworks, which could hinder learning and development for new users.
  • Platform-Specific Limitations
    Being a C++ framework, Crow might face platform-specific issues, and ensuring cross-platform compatibility may require additional effort.
  • Single-Threaded by Default
    Crow is single-threaded by default, which could be a limitation for handling a large number of concurrent connections, although multithreaded operation can be configured.

Oatpp features and specs

  • Lightweight
    Oat++ is designed to be light and efficient, which makes it suitable for developing high-performance applications with minimal resource usage.
  • Simple API
    The framework offers a simple and declarative API, allowing developers to build REST APIs quickly and efficiently without dealing with complex boilerplate code.
  • High Performance
    Oat++ provides high-speed processing and low-latency capabilities, which are essential for demanding web service applications.
  • Modular Architecture
    The framework's modular design allows developers to use only the components they need, making it flexible and adaptable to various use cases.
  • Cross-Platform
    Oat++ supports multiple platforms, enabling the development of applications that can run on different operating systems without significant code changes.

Possible disadvantages of Oatpp

  • Limited Ecosystem
    Compared to more mature frameworks, Oat++ has a smaller community and ecosystem, which might limit the availability of plugins and third-party libraries.
  • Learning Curve
    For developers not familiar with C++ or its modern features, there might be a steeper learning curve to effectively use Oat++.
  • Less Documentation
    The documentation, while improving, may not be as comprehensive as other more established frameworks, potentially posing challenges for new users.
  • Less Popular
    As a relatively less popular framework, finding community support or solutions to specific problems might be more difficult than with more widely-used tools.
  • Feature Limitations
    While sufficient for many use cases, Oat++ may lack some advanced features out-of-the-box compared to larger, more complex frameworks.

  • VueJS goes to microcontroller firmware. This website runs in ESP32 board, with frontend is made with VueJS, TailwindCSS and backend is written in C++.
    I did something similar in the past and used https://github.com/ipkn/crow as web server, in case you want to not implement the web part yourself. Otherwise amazing job! Source: about 2 years ago
  • C++ to Browser JS Framework Recommendations
    Open socket, serve a html page, implement GET/PUT or find framework that do https://github.com/ipkn/crow. Source: almost 3 years ago
  • I forked Crow, an abandoned C++ Web Framework. And I'm currently maintaining it.
    Last year I was looking to port a Flask REST API I made to C++ because speed and why not. I went through a few C++ frameworks but eventually chose the abandoned since 2017 Crow. It was by far the easiest to set up and work with (being inspired by Flask in the first place), and it didn't hurt that it supported Websockets. Source: almost 4 years ago
  • C++ vs C# .net 5
    All right Op feel free to check this micro framework out if your company is going to build a rest api in C++ https://github.com/ipkn/crow . Source: almost 4 years ago
  • cpprestsdk in maintenance mode
    I haven't used any of the following libraries/frameworks but maybe some of them will fit for your needs: - Crow micro web framework. Source: almost 4 years ago

  • Serving Static Files and Single Page Applications on Oat++ (OatPP)
    Oat++(OatPP) is a lightweight C++ Web framework. Out of the box, it provides REST API with built-in JSON serialization/deserialization features, which could be interfaced with your DTOs. - Source: dev.to / 10 months ago
  • Installing and Using The OatPP (Oat++) Library
    OatPP(Oat++) is an open-source lightweight C++ Web Framework. - Source: dev.to / 10 months ago
  • What isn't cpp used on web servers as much as other languages?
    With the right libraries, C++ could be a good fit for applications that want to expose a fast web API to things that need lots of compute (simulators, for instance) or I/O (interactive editing of large datasets). Projects like Oat++ and Crow give me hope that we might see such an ecosystem develop. Source: about 2 years ago
  • How to use C++ as the backend for web dev?
    Maybe use something like https://oatpp.io to create a REST API: C++ in the backend with this library to create a REST server, and the JavaScript/TypeScript frontend to ask for the information. Source: about 3 years ago
  • learning c++: looking for structured project tutorial (web app/api? or other?)
    As for your web problem, I have only used https://oatpp.io/ in the past but I'm sure there are more frameworks like that on the internet. Source: over 3 years ago
