> TypeScript compiler.

|
|
|
|
- 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]}}`
