tsc

Compile a TypeScript file to JavaScript

$ tsc [file.ts]

$ tsc -p [tsconfig.json]

$ tsc -w

$ tsc --strict [file.ts]

$ tsc --target [ES2020] [file.ts]

$ tsc --outDir [dist] [file.ts]

$ tsc --sourceMap [file.ts]

$ tsc --init

tsc [options] [file...]

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.

-p, --project path

Compile project from tsconfig.json at path

Watch input files and recompile on changes

ECMAScript target version (ES3, ES5, ES2015, ES2020, ESNext)

Redirect output to specified directory

Concatenate and emit output to single file

Enable all strict type-checking options

Do not emit outputs; type-check only

Generate corresponding .map source map files

Generate .d.ts declaration files

Skip type checking of declaration files

Enable strict null checks

Raise error on expressions with implied any type

Initialize a tsconfig.json file

tsc requires Node.js and is typically installed via npm (npm install -g typescript). Compilation options on the command line override tsconfig.json settings. Large projects may have slow compile times; consider using --incremental for faster rebuilds.

TypeScript was developed by Microsoft under the lead of Anders Hejlsberg (creator of C# and Turbo Pascal). It was first publicly released in October 2012. The language was designed to address the challenges of large-scale JavaScript development by adding optional static types while maintaining full compatibility with existing JavaScript.
