cdnjs is a free, community-maintained content delivery network that hosts thousands of open-source frontend libraries. It delivers popular JavaScript and CSS assets from a global CDN to speed up website performance and reduce server load, with each library version stored as an immutable snapshot under a predictable directory structure. The platform provides a RESTful JSON API for programmatic access to library metadata, version details, and search functionality. This API returns structured data with HTTP cache headers, including immutable version details cached for nearly a year and library m

This repository provides the downloadable materials and syllabus for a complete Flutter development bootcamp, guiding learners from initial setup through to app deployment. It is structured around the core concepts of building cross-platform mobile applications using the Flutter framework and the Dart language, covering widget-based UI composition, state management, and integration with backend services. The resources focus on practical, hands-on skills, including fetching live data from web APIs and parsing JSON responses, as well as authenticating users and storing data in the cloud using F

node-fs-extra is a Node.js file system extension that provides a set of additional methods to simplify common file and directory operations. It functions as a recursive directory manager, a JSON file processor, and a file asset manipulator, extending the standard library to provide high-level utilities for managing assets on disk. The project distinguishes itself through recursive capabilities, such as duplicating or removing nested folder structures and ensuring that all missing parent directories are automatically generated when creating files or symbolic links. It also integrates a JSON se

tdl is a command-line tool for Telegram account automation, media management, and data archiving. It provides a programmatic interface for downloading and uploading files, forwarding messages, and exporting chat history, member lists, and media into structured JSON files. The project distinguishes itself through a session management system that isolates multiple account identities using unique namespaces. It features expression-based routing for messages and uploads, allowing users to direct content to specific destination chats using custom logic and dynamic caption generation. The tool cov

Ion is an asynchronous HTTP client library for Android that handles network requests, JSON parsing, image loading, and file downloads. It provides a fluent builder pattern for constructing requests and supports automatic JSON deserialization into Java objects using Gson, along with in-memory image caching and multipart form-data encoding. The library distinguishes itself through its support for request cancellation via Future objects, allowing individual or bulk cancellation of in-flight requests to avoid wasted bandwidth and stale callbacks. It also includes proxy-aware request routing for d

jnv is an interactive terminal application for querying and filtering JSON data using jq expressions. It combines a keyboard-driven JSON browser with a real-time jq filter editor, allowing users to navigate, expand, and collapse JSON structures while simultaneously writing and previewing filter results. The tool reads JSON from files or standard input, including JSON Lines format, and provides immediate visual feedback as filters are typed. The application distinguishes itself by integrating jq filter development with live preview and auto-completion, suggesting completions for identifiers, o

This is an ESP32 firmware project that turns a low-power E-Paper display into a weather dashboard. The device runs on battery power with USB-C recharging, periodically fetches weather forecasts from a remote JSON API, and renders them on the screen alongside indoor sensor readings and battery status. The project includes a build-time SVG-to-C header converter that embeds weather icons directly into the firmware binary, and those icons can be rotated programmatically to align with wind direction before display. An error state machine handles API failures, low battery, time sync issues, and Wi-

TagSpaces is an offline-first file tagging and organization platform that lets you manage local files with portable metadata stored directly in filenames or sidecar JSON files, eliminating the need for a central database. It functions as a full-text file search engine, a Kanban board file organizer, a local AI file assistant, an S3-compatible cloud file manager, and a web clipper and bookmark manager, all within a single application. The project distinguishes itself through a local-first architecture where all file operations, indexing, and AI processing run entirely on the device, with cloud

json_repair is a Python library that automatically fixes common JSON syntax errors, such as trailing commas, missing quotes, unclosed brackets, and stray text, producing valid JSON output. It can also complete broken structures by closing unclosed arrays and objects, and fill missing values with sensible defaults like empty strings or null. The library distinguishes itself by handling JSON from large language model outputs, stripping markdown fences, comments, and surrounding prose before parsing. It supports schema-guided repairs, using a JSON Schema to fill missing values, coerce data types

这是一个基于 Web 的 JSON 格式化和可视化工具，专为结构化调试和数据探索而设计。它将原始 JSON 字符串转换为具有语法高亮、缩进指南和可折叠节点的易读树状结构。 该工具提供了一个数据可视化器，用于比较原始服务器响应与解析后的表示形式。它还包含一个控制台导出器，将解析后的 JSON 数据作为全局变量发送到浏览器开发者控制台，以便立即进行检查和操作。 该系统涵盖了 API 响应检查和 JSON 结构分析，允许用户在原始文本和格式化视图之间切换，以验证复杂的嵌套数据。

yyjson is a high-performance C library for parsing, serializing, and manipulating JSON data structures. It functions as a memory-efficient data tool that utilizes custom memory pools and contiguous block allocation to minimize fragmentation and overhead. The project distinguishes itself as a SIMD JSON processor, using hardware-accelerated vector instructions for rapid string validation and parsing. It provides a toolkit for querying, modifying, and patching nested JSON objects and arrays through pointer-based access and path expressions. The library covers a broad range of data manipulation
