tsc 命令

常用示例

说明

tsc is the TypeScript compiler that transforms TypeScript (.ts, .tsx) files into JavaScript (.js). Developed by Microsoft, TypeScript is a superset of JavaScript that adds optional static typing and modern language features. When run without arguments in a directory with tsconfig.json, tsc compiles the project according to that configuration. When files are specified on the command line, tsconfig.json is ignored unless -p is used. The compiler performs type checking to catch errors during development, then emits valid JavaScript. The --strict flag enables comprehensive type checking including strict null checks and no implicit any. Watch mode (-w) monitors source files and recompiles automatically when changes are detected, enabling a fast development workflow.
