    Douya Bean sprouts

    Douya Bean sprouts

    A Material Design app for douban.com

    The open source Material Design Douban client. Among all people who directly access Douban, the most common and consistent usage is around ratings, comments, discoveries, and discussions around movies, TV, books, records, and events (what we call "items"). We will use the ratings and comments that are synchronized with the website as a starting point and basis to reconstruct the discovery and discussion around personal interests on the mobile phone. Douban is never a single website, and the usage of Douban is naturally different. Douban is used to obtain information, but whether the acquisition of information is based on entries and algorithms, or based on neighbors and people, this issue has probably remained unresolved in the multiple revisions of Douban. Douban Broadcasting has been one of the few Android Design applications in China a few years ago. Actively express the characteristics of Douban, such as broadcasting, neighbors, Douyou, etc.

    Lottie

    Lottie

    Render After Effects animations natively on Mobile, Web & React Native

    Lottie is a wonderful library for Android, iOS, Web, and Windows that works by parsing Adobe After Effects animations that have been exported as json with Bodymovin, and then rendering these natively on mobile and on the web! Now you can have beautiful animations without engineers having to recreate everything by hand. Building animations by hand is time consuming, and other animation alternatives like Gifs and Png sequences don’t offer the same flexibility and varied features that Lottie offers. With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever. Take a look at the many beautiful animation possibilities available to you on http://airbnb.io/lottie/

    Mermaid.js to SVG Converter

    Mermaid.js to SVG Converter

    Visualize the diagrams of your projects

    While coding with AI assist, I noticed bigger projects need something more rigid as context so the AI coder doesn't stray away when I try to add new features. You know, to keeps its memory fresh and not change the stuff that already works. The trick is to ask the AI to write a diagram in Mermaid.js format that solidifies the structure of the project and then use that as context to keep the AI reminded at all times what the project is as a whole. This will prevent it from changing things its not supposed to change. This standalone offline web app will convert that mermaid.js code into a visual SVG image so that YOU as a human will be able to understand what the AI think about the structure of your projects so you can see it and fix any misconceptions until the diagram is correct for your project. (Source code is included in the html itself. Open it in a web browser to use.)

    uix-kit

    uix-kit

    A free web kits for fast web design and development

    Uix Kit is not a framework, just a UI toolkit based on some common libraries for building beautiful responsive website. Uix Kit isn't a reusable component structure, mostly custom CSS and JavaScript based. Definitely interesting, and if you're developing mostly web content and not applications this is particularly useful. It is a web dev build tool/scaffold that does not depend on any framework. You can import any external libraries/frameworks or native ES Modules for production. The generated core file in the dist directory can be used separately in any website. Support JS, HTML, and SASS component library automatically packaged. It is used to develop the full-static website (HTML templates or for dynamic language integration). The demo depends on jQuery (you can completely rewrite the script if needed). And dist DOES NOT bundle any third-party script and style library, all libraries are loaded externally in the HTML file.
