tsc

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

• Compile a TypeScript file foobar.ts into a JavaScript file foobar.js:

tsc {{foobar.ts}}

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

tsc --target {{ES5|ES2015|ES2016|ES2017|ES2018|ESNEXT}} {{foobar.ts}}

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

tsc --outFile {{output.js}} {{input.ts}}

• Compile all .ts files of a TypeScript project defined in a tsconfig.json file:

tsc --build {{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 --watch
