ts-node 命令

常用示例

说明

ts-node is a TypeScript execution engine for Node.js that compiles and runs TypeScript files on-the-fly without a separate build step. By default it performs full type checking at runtime, reporting type errors before execution begins. The --transpile-only mode skips type checking for significantly faster startup, which is useful during development when your editor already provides type feedback. The --swc flag uses the SWC transpiler (written in Rust) for an even greater speed improvement, and implies --transpileOnly. ESM mode (--esm) handles ES module imports and is needed when working with import/export syntax natively. The built-in REPL provides an interactive TypeScript environment for experimentation. Configuration is loaded from tsconfig.json by default, and a custom config can be specified with -P. The tool integrates well with development workflows using ts-node-dev or nodemon for automatic restart on file changes.
