Rust Course
It has been the world's most popular language for 8 consecutive years
The Rust语言圣经 (Rust Language Bible) is a comprehensive, Chinese-language Rust tutorial that aims to take learners from beginner concepts to advanced mastery. The course is carefully designed with a structured catalog, vivid and approachable language, and an engaging style that avoids the dry and mechanical tone of many technical books. It covers the basics of Rust, such as ownership, borrowing, lifetimes, traits, and generics, but also dives deep into advanced topics like performance optimization, linked list implementations, async programming with Tokio, standard library internals, Cargo usage, and WebAssembly development. The project emphasizes practical learning through exercises, helping users approach Rust study as if it were a university course. It also provides a "Cookbook" section of practical code snippets for common tasks such as file operations, regex handling, and database interactions, allowing learners to quickly reference solutions without searching externally. -

Vue-Socket.io
Socket.io implementation for Vuejs and Vuex
Vue-Socket.io is a Socket.IO integration library for Vue.js and Vuex applications. It allows Vue components to listen for real-time socket events through a clean, framework-friendly API. The project helps developers connect frontend applications to Socket.IO servers without manually wiring every event listener and lifecycle behavior. It also supports Vuex integration, making it easier to route socket events into centralized state management. Vue-Socket.io is especially useful for chat apps, dashboards, notifications, collaborative interfaces, live counters, and other real-time user experiences. Because the project is centered on Vue 2-era usage, modern Vue teams should evaluate compatibility before using it in a new application. -

Vuex
Centralized State Management for Vue.js
Vuex is a centralized state management pattern and library for Vue.js applications. It stores all the components in an application following rules that ensure the state is only mutated in a predictable manner. Unlike other management patterns, Vuex defines and separates the concepts involved in state management, and enforces rules that maintain independence between views and states. It is also a library implementation that's specifically tailored for Vue.js, so as to take advantage of its granular reactivity system for efficient updates. Vuex is ideal for building a medium-to-large-scale SPA, as it is better at handling state outside of Vue components. -

ai-renamer
A Node.js CLI that uses Ollama and LM Studio models
ai-renamer is a Node.js-based command-line tool that uses large language models to automatically rename files based on their content, enabling more meaningful and organized file management. Instead of relying on manual naming or metadata, the tool analyzes the actual content of files, including images, videos, and documents, to generate descriptive and context-aware filenames. It integrates with local and cloud-based AI providers such as Ollama, LM Studio, and OpenAI, allowing users to choose between offline and API-based workflows depending on their needs. The tool supports batch processing, making it particularly useful for organizing large collections of files quickly and efficiently.

bignumber.js
A JavaScript library for arbitrary-precision decimal arithmetic
bignumber.js is a JavaScript library for arbitrary-precision decimal and non-decimal arithmetic. Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal. Replicates the toExponential, toFixed, toPrecision and toString methods of JavaScript's Number type. Includes a toFraction and a correctly-rounded squareRoot method. Supports cryptographically secure pseudo-random number generation. Wide platform compatibility, uses JavaScript 1.5 (ECMAScript 3) features only. If a smaller and simpler library is required see big.js. It's less than half the size but only works with decimal numbers and only has half the methods. It also has fewer configuration options than this library, and does not allow NaN or Infinity. See also decimal.js, which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits. -

body-parser
Node.js body parsing middleware
Node.js body parsing middleware. Parse incoming request bodies in a middleware before your handlers, available under the req.body property. As req.body's shape is based on user-controlled input, all properties and values in this object are untrusted and should be validated before trusting. For example, req.body.foo.toString() may fail in multiple ways, for example the foo property may not be there or may not be a string, and toString may not be a function and instead a string or other user input. The bodyParser object exposes various factories to create middlewares. All middlewares will populate the req.body property with the parsed body when the Content-Type request header matches the type option, or an empty object ({}) if there was no body to parse, the Content-Type was not matched, or an error occurred. -

css-loader
CSS Loader
The CSS-loader interprets @import and URL() like import/require() and will resolve them. Add the plugin to your webpack config. Run webpack via your preferred method. Allows to enable/disable handling the CSS functions URL and image-set. If set to false, CSS-loader will not parse any paths specified in URL or image-set. A function can also be passed to control this behavior dynamically based on the path to the asset. Starting with version 4.0.0, absolute paths are parsed based on the server root. Using local value requires you to specify :global classes. Using global value requires you to specify :local classes. Using pure value requires selectors must contain at least one local class or id. Styles can be locally scoped to avoid globally scoping styles. The syntax :local(.className) can be used to declare className in the local scope. The local identifiers are exported by the module. -

csv-parser
Streaming csv parser inspired by binary-csv that aims to be faster
csv-parser is a streaming CSV parsing library for Node.js designed for efficiency and correctness. It implements the stream API native to Node, allowing you to pipe a file or readable stream into the parser and process each row (as a JavaScript object or array) as soon as it's parsed — which is crucial for handling large CSV files without loading them entirely into memory. The parser handles standard CSV semantics including quoted fields, variable delimiters, escape sequences, and optional headers; this makes it robust for a variety of CSV dialects you might encounter. Because it works incrementally (row by row), it is well suited for ETL pipelines, data ingestion workflows, CSV-to-database imports, or any context where you need to process or transform large tabular data in Node.js efficiently. Using the .on('data') / .on('end') (or equivalent async patterns), you can accumulate, filter, transform, or stream data further downstream without waiting for the whole file. -

jQuery Terminal
JavaScript library for creating web-based terminals
jQuery Terminal is a JavaScript library for creating command-line interpreters in your applications. You can use this JavaScript Terminal library to create interactive web-based terminal applications on your website. Where commands are defined by you. You can define them on the server or in the browser's JavaScript. It can automatically call JSON-RPC service when the user types a command. Alternatively, you can provide an object with methods; each method will be invoked on the user's command (the python command can create python interpreter). An object can have nested objects which will create a nested interpreter (you can create an interactive menu of adventure games with this). You can also use a function in which you can parse user commands by yourself (you have full control of what users type into the terminal). It's ideal if you want to provide additional functionality for power users. -

jsdom
JavaScript implementation of various web standards, for use with Node
jsdom is a pure-JavaScript implementation of many web standards, notably the WHATWG DOM and HTML Standards, for use with Node.js. In general, the goal of the project is to emulate enough of a subset of a web browser to be useful for testing and scraping real-world web applications. The latest versions of jsdom require Node.js v10 or newer. To use jsdom, you will primarily use the JSDOM constructor, which is a named export of the jsdom main module. Pass the constructor a string. The resulting object is an instance of the JSDOM class, which contains a number of useful properties and methods besides window. In general, it can be used to act on the jsdom from the "outside," doing things that are not possible with the normal DOM APIs. For simple cases, where you don't need any of this functionality, we recommend a coding pattern. -
