  • Cross-platform compatibility
    Emscripten enables developers to compile C and C++ code to WebAssembly or JavaScript, allowing the same codebase to run on multiple platforms, such as browsers and node.js, without needing additional platform-specific adaptations.
  • Leverage existing libraries
    Developers can utilize a vast ecosystem of existing C and C++ libraries by compiling them for the web, saving time and resources required for rewriting or finding alternatives developed in JavaScript.
  • Performance optimization
    Emscripten's compilation to WebAssembly provides near-native performance for web applications, making it suitable for compute-intensive tasks like gaming, simulations, and data processing.
  • Familiar toolchain
    Developers can use familiar tools like CMake and others as part of their Emscripten workflow, making it easier for those with C/C++ backgrounds to adapt and integrate into their web development processes.

Possible disadvantages

  • Steep learning curve
    Developers unfamiliar with C and C++ may find Emscripten challenging to use effectively, as it requires knowledge of these languages and their build systems to create and debug applications.
  • Limitations in browser environments
    Certain features of C/C++ may not translate directly to web environments due to browser sandboxing constraints, leading to potential issues with file I/O, threading, and other system-level operations.
  • Code size
    Compiled WebAssembly and JavaScript code can sometimes be large, potentially affecting load times and performance, especially on lower-end devices with restrictive bandwidth or processing capabilities.
  • Debugging complexity
    Debugging WebAssembly code can be more complex than traditional JavaScript, requiring specialized tooling and techniques to trace and fix issues effectively.

  • How I Built a Reverse Video Search Engine on One Home PC
    The geometry check has to give the same answers in the browser as on the server. So instead of rewriting it in JavaScript, I compiled the same OpenCV 4.14 code paths to WebAssembly with Emscripten: one C++ file, run in a pool of workers. - Source: dev.to / 6 days ago
  • Ask HN: Qt style "Signals and Slots" based JavaScript UI library?
    The first thing that comes to mind is that Qt now has a WebAssembly port[1] using Emscripten[2], so depending on your use-case, you could possibly just run Qt on the Web platform and avoid the need for a JavaScript framework entirely.... - Source: Hacker News / over 1 year ago

    Me and a friend build our own Graphics engines based on https://learnopengl.com I can highly recommend this to everyone who gets started with computer graphics. It is a lot of new information but not the most modern Graphics library, but... - Source: Hacker News / about 2 years ago
