tsc-output-format

tsc-output-format v1.1.1 is a TypeScript library and CLI tool that formats tsc diagnostic output into JSON, GitHub Actions annotations, grouped text, and more. Released in March 2025 with monthly updates, it supports pretty mode, watch mode, and custom formatters/parsers. Unlike other tsc output processors, it provides a pluggable architecture and first-class TypeScript types. Minimal bundle size (<5KB) and zero runtime dependencies make it suitable for CI pipelines.
