    create-dmg

    create-dmg

    Create a good-looking DMG for your macOS app in seconds

    ...You can either pay for a GUI app where you have to customize an existing design or you can run some homebrewed Bash script and you still have to design it. This tool does everything for you, so you can play with your cat instead. The DMG detects the minimum runtime of the app, and uses ULFO (macOS 10.11 or later) or UDZO as appropriate. The resulting image has the filename App Name 0.0.0.dmg, for example, Lungo 1.0.0.dmg. It will try to code sign the DMG, but the DMG is still created and fine even if the code signing fails, for example if you don't have a developer certificate.

    Lottie-Web

    Lottie-Web

    Render After Effects animations natively

    Lottie-Web renders vector animations exported from Adobe After Effects as lightweight JSON, playing them in the browser via SVG or Canvas. Animations remain crisp at any resolution, load quickly compared to videos or GIFs, and can be controlled programmatically for interactivity. The runtime supports playback options like loop, autoplay, segment control, and event hooks, making it easy to sync motion with UI state. Because animations are data rather than pixels, designers and developers can collaborate: designers export with the Bodymovin plugin, and developers integrate the JSON with minimal code. The renderer handles masks, shapes, and keyframe timing to closely mirror After Effects behavior within web constraints. ...

    Eva.js is a front-end game engine for creating interactive projects

    A front-end game engine specifically for creating interactive game projects. Eva.js provides out-of-box game components for developers to use right away. Yes, it's simple and elegant! Eva.js is powered by efficient runtime and rendering pipeline (Pixi.JS) which makes it possible to unleash the full potential of your device. Thanks to the ECS(Entity-Component-System) structure, you can expand your needs by highly customizable APIs. The only limitation is your imagination! Eva.js relies on canvas in HTML for drawing. If the width and height in the design draft are fixed (for example, 750px*1000px) and occupy the full screen, we can set the CSS width of the canvas to 100% and the height to auto.
