Input:: //// [/lib/lib.d.ts] Output:: /lib/tsc Version FakeTSVersion tsc: The TypeScript Compiler - Version FakeTSVersion COMMON COMMANDS tsc Compiles the current project (tsconfig.json in the working directory.) tsc app.ts util.ts Ignoring tsconfig.json, compiles the specified files with default compiler options. tsc -b Build a composite project in the working directory. tsc --init Creates a tsconfig.json with the recommended settings in the working directory. tsc -p ./path/to/tsconfig.json Compiles the TypeScript project located at the specified path. tsc --help --all An expanded version of this information, showing all possible compiler options tsc --noEmit tsc --target esnext Compiles the current project, with additional settings. COMMAND LINE FLAGS --help, -h Print this message. --watch, -w Watch input files. --all Show all compiler options. --version, -v Print the compiler's version. --init Initializes a TypeScript project and creates a tsconfig.json file. --project, -p Compile the project given the path to its configuration file, or to a folder with a 'tsconfig.json'. --build, -b Build one or more projects and their dependencies, if out of date --showConfig Print the final configuration instead of building. COMMON COMPILER OPTIONS --pretty Enable color and formatting in TypeScript's output to make compiler errors easier to read type: boolean default: true --target, -t Set the JavaScript language version for emitted JavaScript and include compatible library declarations. one of: es3, es5, es6, es2015, es2016, es2017, es2018, es2019, es2020, es2021, esnext default: ES3 --module, -m Specify what module code is generated. one of: none, commonjs, amd, system, umd, es6, es2015, es2020, esnext --lib Specify a set of bundled library declaration files that describe the target runtime environment. one or more: es5, es6, es2015, es7, es2016, es2017, es2018, es2019, es2020, es2021, esnext, dom, dom.iterable, webworker, webworker.importscripts, webworker.iterable, scripthost, es2015.core, es2015.collection, es2015.generator, es2015.iterable, es2015.promise, es2015.proxy, es2015.reflect, es2015.symbol, es2015.symbol.wellknown, es2016.array.include, es2017.object, es2017.sharedmemory, es2017.string, es2017.intl, es2017.typedarrays, es2018.asyncgenerator, es2018.asynciterable, es2018.intl, es2018.promise, es2018.regexp, es2019.array, es2019.object, es2019.string, es2019.symbol, es2020.bigint, es2020.promise, es2020.sharedmemory, es2020.string, es2020.symbol.wellknown, es2020.intl, es2021.promise, es2021.string, es2021.weakref, es2021.intl, esnext.array, esnext.symbol, esnext.asynciterable, esnext.intl, esnext.bigint, esnext.string, esnext.promise, esnext.weakref --allowJs Allow JavaScript files to be a part of your program. Use the `checkJS` option to get errors from these files. type: boolean default: false --checkJs Enable error reporting in type-checked JavaScript files. type: boolean default: false --jsx Specify what JSX code is generated. one of: preserve, react-native, react, react-jsx, react-jsxdev default: undefined --declaration, -d Generate .d.ts files from TypeScript and JavaScript files in your project. type: boolean default: `false`, unless `composite` is set --declarationMap Create sourcemaps for d.ts files. type: boolean default: false --emitDeclarationOnly Only output d.ts files and not JavaScript files. type: boolean default: false --sourceMap Create source map files for emitted JavaScript files. type: boolean default: false --outFile Specify a file that bundles all outputs into one JavaScript file. If `declaration` is true, also designates a file that bundles all .d.ts output. --outDir Specify an output folder for all emitted files. --removeComments Disable emitting comments. type: boolean default: false --noEmit Disable emitting files from a compilation. type: boolean default: false --strict Enable all strict type-checking options. type: boolean default: false --types Specify type package names to be included without being referenced in a source file. --esModuleInterop Emit additional JavaScript to ease support for importing CommonJS modules. This enables `allowSyntheticDefaultImports` for type compatibility. type: boolean default: false You can learn about all of the compiler options at https://aka.ms/tsconfig-reference exitCode:: ExitStatus.DiagnosticsPresent_OutputsSkipped
