    Bundlesize

    Bundlesize

    Keep your bundle size in check

    Add it to your scripts in package.json. Or you can use it with npx from NPM 5.2+. bundlesize accepts an array of files to check. You can give a different file by using the --config flag. If the names of your build files are not predictable, you can use the glob pattern to specify files. This is common if you append a hash to the name or use a tool like create-react-app/nextjs. It will match multiple files if necessary and create a new row for each file. By default, bundlesize gzips your...

    Enterprise

    Enterprise

    The Enterprise™ programming language

    ...Rather than aiming to solve a practical technical problem, it serves as a parody of enterprise-grade software, showcasing exaggerated patterns such as excessive abstraction, redundant layers, and convoluted architectures. The repository is often used as a teaching tool to highlight anti-patterns in software engineering, helping developers recognize and avoid overly complicated designs in real-world projects. Despite its humorous nature, the project is technically functional and demonstrates how complexity can accumulate when design principles are misapplied. It resonates particularly with developers who have experience in large organizations, where similar patterns sometimes emerge unintentionally.

    A-Frame Inspector

    Visual inspector tool for A-Frame

    ...Hit record, move around inside the VR headset, interact with objects with the controller. Then replay that recording back on any computer for rapid development and testing. Reduce the amount of time going in and out of the headset. The A-Frame Inspector is a visual tool for inspecting and tweaking scenes. The Inspector is similar to the browser’s DOM inspector but tailored for 3D and A-Frame. Not only can we open our local scenes inside the Inspector, we can open any A-Frame scene in the wild using the Inspector (as long as the author has not explicitly disabled it).
