JSON Crack is an open-source, browser-based tool for visualizing, formatting, converting, and exploring JSON, YAML, CSV, and XML data as interactive graphs. The monorepo (Turborepo) contains four workspaces: a Next.js web app (apps/www) that provides the full editor experience with a Monaco-based text editor, split-view layout, graph canvas, and various utility modals (jq, JSONPath, schema validation, code generation); a VS Code extension (apps/vscode) that embeds the same graph view as a webview panel; a Chrome extension (apps/chrome-extension) that injects a 'Raw'/'Graph' toggle on any JSON page; and a reusable React component package (packages/jsoncrack-react) that exposes `JSONCrack` as a standalone component along with a `parseGraph` utility and TypeScript types. All data processing happens client-side — the app is a fully static Next.js export served behind NGINX. The architecture is frontend-only, relying on Zustand for state, reaflow for graph layout, react-zoomable-ui for pannable/zoomable canvas, and jsonc-parser for AST-driven parsing. The codebase is well-organized, with clear separation of concerns, good TypeScript coverage, and unit tests in the core package.
