fx is a terminal-based JSON viewer and processor written in Go that provides an interactive interface for exploring and manipulating JSON data directly from the command line. The project is maintained by antonmedv and serves as a specialized tool for developers who need to work with JSON structures in terminal environments without leaving their command-line workflow.
The core functionality centers on JSON visualization with syntax highlighting, allowing users to view formatted JSON output in the terminal with color-coded elements for improved readability. Beyond simple viewing, fx enables filtering and querying of JSON data, making it possible to extract specific information from complex nested structures. The tool also handles JSON formatting, automatically prettifying raw or minified JSON input for easier inspection. These capabilities position fx as both a viewer for understanding JSON structure and a processor for extracting and transforming JSON data.
Bug reports number 8, while 2 items are marked as help wanted, indicating areas where community contributions are explicitly encouraged.
The repository is classified across multiple relevant domains including JSON viewer, command-line tool, interactive interface, data exploration, JSON formatting, data visualization, filtering, querying, syntax highlighting, and terminal application. This broad classification reflects the tool's multifaceted approach to JSON handling. The project is licensed under MIT, making it freely available for both personal and commercial use.
Documentation is centralized at fx.wtf, the project's homepage, providing comprehensive guidance for users. The repository exists within a broader ecosystem of terminal utilities created by antonmedv, including walk for file management, howto for command assistance via LLM integration, and countdown for terminal timers. This collection suggests a philosophy of building focused, single-purpose command-line tools that integrate well with terminal workflows. The presence of a Crow Watch integration banner in the repository indicates community engagement and monitoring infrastructure for the project.
