    WorkerVless2sub

    WorkerVless2sub

    Automate batch replacement to generate subscription generators

    WorkerVless2sub is a dedicated subscription generator focused on providing “preferred line” subscriptions by processing VMess, VLESS, Trojan nodes, filtering and replacing automatically via a Cloudflare Worker script. The idea is you supply node lists (or use existing APIs/CSV sources) and the worker filters them by criteria like speed or reliability and then emits a subscription link for end-users. It supports deployment on Cloudflare Pages or Workers, offers configuration via variables like HOST, UUID, PATH, ADD, ADDAPI etc., and has an Apache-2.0 license. The tool supports both IPv4 and IPv6 node sources, speed test CSV inputs, and logic to drop nodes that don’t meet the threshold (DLS variable). It has a sizeable star count and forks indicating broader adoption in self-hosted proxy subscription communities. The README also explicitly warns about hosting personal private nodes in the script if intending public use.

    css-spinner

    css-spinner

    Small, elegant pure css spinner for ajax or loading animation

    Open source CSS loading animations dedicated for speed, simplicity & dev-friendly. Loading.io's CSS spinner uses CSS Animation, which is wildly supported by all modern browsers such as Google Chrome and Mozilla Firefox. However, the Microsoft Internet Explorer version earlier than 10 doesn't support CSS Animation. To support older IE, you have to use a GIF format image. Choose one from loading.io's online spinner gallery and you can customize a unique loader GIF with our icon editor easily. Some older browsers need prefixes like '-WebKit-' to use CSS Animation. To minimize file size, we omitted all vendor prefixes in loaders' CSS, but you can customize this by building CSS from the source. We also provide stylus and pug source files for better integrating these spinners into your project. Find corresponding stylus and pug files for your desired spinners under src/ folders.
