LLVM features and specs

  • Modularity
    LLVM is designed to be modular and flexible, allowing developers to utilize only the components they need for their specific tasks. This makes it versatile for a wide range of use cases.
  • Optimization
    LLVM provides advanced optimization techniques that allow for efficient code execution across various platforms. It utilizes a variety of standard and state-of-the-art optimization passes to improve performance.
  • Cross-Platform Support
    LLVM supports a wide range of architectures and platforms, enabling developers to build and deploy applications across multiple target environments without needing to make significant code changes.
  • Rich Ecosystem
    The LLVM project includes a wide array of tools and libraries, such as Clang and LLDB, that enhance development capabilities and provide comprehensive support for different programming languages.
  • Community and Industry Adoption
    LLVM has a robust and active community, along with backing from major technology companies. This means consistent updates, improvements, and a broad support network for troubleshooting and enhancements.

Possible disadvantages of LLVM

  • Complexity
    Due to its extensive feature set and flexibility, LLVM can be complex to understand and use, particularly for newcomers who may find its detailed API and documentation challenging.
  • Resource Intensive
    The advanced optimizations and capabilities provided by LLVM can require significant compute resources, which might not be suitable for all systems or use cases, particularly those with limited capabilities.
  • Steep Learning Curve
    LLVM's power and flexibility come with a steep learning curve, demanding a strong understanding of compiler design and architecture to fully leverage its potential.
  • Limited Legacy Support
    While LLVM supports many modern architectures, its focus on newer platforms means that it may offer limited functionality for legacy systems or older processor architectures.
  • Lack of High-Level Language Features
    LLVM is primarily focused on compiler and intermediate representation infrastructure, which means that it does not provide some high-level language features or abstractions unless provided by front-end tools.

Crow features and specs

  • Asynchronous Handling
    Crow supports asynchronous request handling, allowing for efficient management of high numbers of simultaneous connections.
  • Modern C++ Standards
    Utilizes modern C++ features to ensure robust and efficient performance, leveraging C++11 and newer standards.
  • Simple and Lightweight
    Designed to provide a web application framework with simplicity and minimal resource usage, making it suitable for embedded systems.
  • JSON Parsing
    Includes built-in support for parsing and handling JSON, making it easier to work with web APIs and RESTful services.
  • Routing
    Offers flexible routing capabilities, allowing for easy mapping of URLs to handlers with path parameters and regular expressions.

Possible disadvantages of Crow

  • Limited Ecosystem
    Compared to more established frameworks, Crow has a smaller community and fewer third-party libraries and tools available.
  • Learning Curve
    Requires familiarity with modern C++ features, which might be challenging for developers not well-versed in these standards.
  • Lack of Comprehensive Documentation
    The documentation may not be as extensive or detailed as other frameworks, potentially making it harder to troubleshoot or learn advanced features.
  • Scalability
    While suitable for many use cases, it might not be the best choice for very large-scale applications requiring extensive middleware functionality.

  • Why you should keep an eye on Apache DataFusion and its community.
    Similarly, LLVM revolutionized the world of programming languages and compilers. Since its creation, we've seen many new languages being created of increased complexity. - Source: dev.to / 10 months ago
  • Yes, Ruby is fast, but…
    In conclusion, none of the proposed changes to the Ruby version of the code makes a dent in the Crystal version. This is not entirely Crystal's doing: it uses the LLVM backend, which generates very optimized binaries. - Source: dev.to / about 1 year ago
  • Playing with DragonRuby Game Toolkit (DRGTK)
    This Ruby implementation is based on mruby and LLVM and it’s commercial software but cheap. - Source: dev.to / 12 months ago

  • Transport agnostic Websocket library
    I recommend Crow, it's a web framework that supports HTTP and Websockets. It's a bit larger than being only there to just let you compose or decode a packet. But I'm pretty sure everything you mentioned is there already :). Source: almost 3 years ago
  • Can I use C++ in the backend ?? Any frameworks there ??
    I've been working on Crow for quite a while now, it's a pretty cool framework IMO. Source: almost 3 years ago
  • making a web server in c++?
    If you really want to use C++, check out something like Crow, https://crowcpp.org/ and same thing, you can pass messages between the server and your application. Source: about 3 years ago
  • Crow finally gets rid of `CROW_MAIN` macro
    Crow is a C++ web framework being developed and maintained by myself and a couple developers. Source: over 3 years ago
  • C or C++ as web app backend?
    Https://crowcpp.org/ (C++ API similar to Python flask). Source: over 3 years ago
