## Description

Ts-json-schema-generator is a command-line tool and Node.js library that automatically generates standard JSON validation schemas directly from TypeScript source files and type definitions. Operating as a static code analyzer and schema compilation engine, it inspects type definitions and interfaces to understand structural data shapes without requiring runtime execution. It uses static program analysis by initializing a virtual compiler instance to resolve complex generic types, imports, and type relationships across source files.

The project translates extracted types into standard validation specifications through an AST-based type inspection and transformation pipeline. It provides extensibility through a formatter plugin system that intercepts the serialization of specific structural types, alongside custom syntax parser extensions that enable the interpretation of non-standard code constructs by plugging custom parsing rules directly into the early code analysis phase.

Users can operate the software via a declarative command-line interface using path glob patterns and configuration flags, or embed the generation routines programmatically within custom scripts and server programs. Additional configuration options allow direct control over compiler settings, custom parsing rules, and specialized schema output formatting.
