tsc

TypeScript compiler. More information: https://www.typescriptlang.org/docs/handbook/compiler-options.html.

• Initialize a TypeScript project:

tsc --init

• Compile a TypeScript file into a JavaScript file with the same name:

tsc {{path/to/file.ts}}

• Compile a TypeScript file into JavaScript using a specific target syntax (default is ES3):

tsc {{[-t|--target]}} {{ES5|ES2015|ES2016|ES2017|ES2018|ESNEXT|...}} {{path/to/file.ts}}

• Compile a TypeScript file into a JavaScript file with a custom name:

tsc --outFile {{path/to/output_file.js}} {{path/to/input_file.ts}}

• Compile all .ts files of a TypeScript project defined in a tsconfig.json file (--build can be omitted to build the project in the current working directory):

tsc {{[-b|--build]}} {{path/to/tsconfig.json}}

• Run the compiler using command-line options and arguments fetched from a text file:

tsc @{{args.txt}}

• Type-check multiple JavaScript files, and output only the errors:

tsc --allowJs --checkJs --noEmit {{src/**/*.js}}

• Run the compiler in watch mode, which automatically recompiles code when it changes:

tsc {{[-w|--watch]}}
