    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.

    D3

    D3

    Bring data to life with SVG, Canvas and HTML

    D3.js is a JavaScript library for manipulating documents based on data. D3 helps you bring data to life using HTML, SVG, and CSS. D3’s emphasis on web standards gives you the full capabilities of modern browsers without tying yourself to a proprietary framework, combining powerful visualization components and a data-driven approach to DOM manipulation. D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction. D3 is not a monolithic framework that seeks to provide every conceivable feature. Instead, D3 solves the crux of the problem: efficient manipulation of documents based on data. This avoids proprietary representation and affords extraordinary flexibility, exposing the full capabilities of web standards such as HTML, SVG, and CSS.

    The warehouse's SpringBoot-based rights management system

    The warehouse's SpringBoot-based rights management system is easy to read and understand, and the interface is simple and beautiful. The core technology uses Spring, MyBatis, and Shiro without any other heavy dependencies. I have always wanted to make a background management system, and I have seen many excellent open source projects but found no suitable ones. So I started to write a background system in my spare time. So there is Zoe. She can be used for all web applications, such as website management background, website member center, CMS, CRM, OA. All front-end and back-end codes are very compact and easy to use after encapsulation, and the probability of errors is low. Also supports mobile client access. The system will continue to update some useful functions. The user is the system operator, and this function mainly completes the system user configuration. Configure the system organization (company, department, group).

    Site Kit for WordPress

    Site Kit for WordPress

    Site Kit is a one-stop solution for WordPress users

    Site Kit is a first-party WordPress plugin that brings key Google services into a single dashboard so site owners can see how their content performs and fix issues without leaving wp-admin. After a guided setup and verification flow, it connects properties to Search Console, Analytics, AdSense, PageSpeed Insights, and other services, surfacing the most relevant metrics per page and per site. The plugin focuses on clarity: traffic sources, search queries, top pages, and monetization signals appear alongside actionable performance recommendations. It also handles authentication and permission scopes securely, so multiple collaborators can access insights without sharing credentials. Widgets and contextual panels put data where it’s needed—for example, on the post list or edit screen—reducing tab-switching. For developers and agencies, Site Kit simplifies client onboarding and standardizes reporting across many sites.

    VueGL is a component library for rendering 3D graphics with Vue.js and three.js. Using VueGL, you can handle WebGL very easily. In addition, drawn graphics are responsively re-rendered when detecting data changes. Vue.js is one of the very popular frameworks for building web apps or interactive websites. three.js is a 3D graphics library to uses WebGL. It provides classes wrapping WebGL APIs. They aim for different targets to be rendered, Vue.js for DOM and three.js for WebGL context. These APIs are completely different and that causes a mess when we want them to work together.

    html-loader

    html-loader

    HTML Loader

    Exports HTML as a string. HTML is minimized when the compiler demands. The true value enables the processing of all default elements and attributes, the false value disables the processing of all attributes. Allows you to specify which tags and attributes to process, filter them, filter urls and process sources starting with /. Allows to setup which tags and attributes to process and how, as well as the ability to filter some of them. Filter can also be used to extend the supported elements and attributes. By default, the parser in html-loader interprets content inside noscript tags as #text, so processing of content inside this tag will be ignored. A very common scenario is exporting the HTML into their own .html file, to serve them directly instead of injecting with javascript.

    JSON5

    JSON5

    JSON5 — JSON for Humans

    JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. JSON5 was started in 2012, and as of 2022, now gets >65M downloads/week, ranks in the top 0.1% of the most depended-upon packages on npm, and has been adopted by major projects like Chromium, Next.js, Babel, Retool, WebStorm, and more. It's also natively supported on Apple platforms like MacOS and iOS. Formally, the JSON5 Data Interchange Format is a superset of JSON (so valid JSON files will always be valid JSON5 files) that expands its syntax to include some productions from ECMAScript 5.1 (ES5). It's also a subset of ES5, so valid JSON5 files will always be valid ES5. This JavaScript library is a reference implementation for JSON5 parsing and serialization and is directly used in many of the popular projects mentioned above.

Sakura supports extremely easy theming support using variables for duotone color scheming. Comes with several existing themes, and can be found in the CSS folder of this repository. Don't want to develop using sakura, but instead want to use it on websites with outdated 90's design (i.e. no CSS)? Quick prototyping, especially when working on backend sites and can't yet be bothered to fidget with CSS/HTML. Building a quick (but pretty) site/blog for your best friend or aunt! No need to remember tons of different class names for every other CSS framework. Works amazingly with markdown generated HTML pages (eliminates the need of hacks like including .img img-responsive in markdown-parser generated <img></img> tags).
