Youch is a TypeScript library that pretty prints JavaScript errors as readable HTML pages for the web or ANSI-formatted output for the terminal. It renders stack traces, error causes, and metadata with syntax highlighting and code editor integration.
Use cases
- display readable error pages in a web app during development
- pretty print stack traces in the terminal for CLI tools
- render error causes and metadata in a formatted HTML page
- customize syntax highlighting and styles for error output
- open stack trace locations directly in a code editor
When to choose
- you want developer-friendly error rendering in Node.js web frameworks or CLIs
- you need both HTML and terminal error output from one library
- you want stack traces with source context, causes, and editor links
When to avoid
- you need error tracking and aggregation in production (use Sentry or similar)
- you only need simple logging of error messages without formatting
