ts-node is a TypeScript execution engine and REPL for Node.js that JIT-transforms TypeScript into JavaScript so it can be run directly without a precompile step. It hooks Node's module loading APIs, supporting source maps, tsconfig.json parsing, optional typechecking, native ESM, and third-party transpilers.

Use cases

• run typescript files directly with node
• typescript repl for node.js
• execute ts scripts without compiling
• use typescript in node scripts with shebang
• integrate typescript with test runners and debuggers
• run typescript with native esm modules

When to choose

• you want to run TypeScript on Node.js without a separate build step
• you need a TypeScript REPL or standalone script execution
• you want tsconfig.json-aware execution with source maps and optional typechecking
• you need to plug TypeScript execution into test runners, debuggers, or CLI tools

When to avoid

• you are building for production and should precompile TypeScript ahead of time
• you only need fast transpilation without typechecking and prefer a bundler-based runner
• your project uses Deno, Bun, or another runtime with built-in TypeScript support
