This is the official XRP Ledger Developer Portal (xrpl.org), a comprehensive documentation and education website for developers building on the XRP Ledger. Built on the Redocly Realm documentation framework, it serves as a static site with React-based UI components, interactive developer tools (WebSocket API tool, TOML checker, transaction sender), and a large corpus of runnable code samples in JavaScript, Python, Go, and Java. The portal provides conceptual documentation, API references, tutorials, blog posts, and marketing pages for the XRP Ledger ecosystem. The architecture is a statically generated site with client-side interactivity. The custom theme includes a Brand Design System (BDS) with reusable React components (buttons, cards, grids, carousels), Markdoc custom tags, and plugins for indexing code samples and blog posts. Interactive tools connect to XRPL testnet/mainnet via WebSocket/JSON-RPC. The codebase also includes maintenance scripts (link checker, release note generator) and a localization system with Japanese translations. While primarily a documentation portal, the repository contains substantial application code in the form of interactive developer tools and a design system. The code samples are educational but not part of the running application. The codebase shows signs of ongoing modernization (migration from jQuery to React, BDS 2026 updates) but retains legacy components and some cross-language duplication in tutorials.
