tsc CLI Options

Show all compiler options.

Initializes a TypeScript project and creates a tsconfig.json file.

Set the language of the tsc output

Print the final configuration instead of building.

Build one or more projects and their dependencies, if out of date

Show what would be built (or deleted, if specified with '--clean')

Enable verbose logging.

Remove a list of directories from the watch process.

Specify what approach the watcher should use if the system runs out of native file watchers.

Watch input files.

Specify how the TypeScript watch mode works.

Enable importing files with any extension, provided a declaration file is present.

Allow JavaScript files to be a part of your program. Use the checkJS option to get errors from these files.

Allow accessing UMD globals from modules.

Disable error reporting for unused labels.

Have recompiles in projects that use incremental and watch mode assume that changes within a file will only affect files directly depending on it.

Manually set the text encoding for reading files

Enable constraints that allow a TypeScript project to be used with project references.

Generates .d.ts files from TypeScript and JavaScript files in your project.

Create sourcemaps for d.ts files.

Reduce the number of projects loaded automatically by TypeScript.

Opt a project out of multi-project reference checking when editing.

Emit more compliant, but verbose and less performant JavaScript for iteration.

Only output d.ts files and not JavaScript files.

Emit additional JavaScript to ease support for importing CommonJS modules. This enables allowSyntheticDefaultImports for type compatibility.

Enable experimental support for TC39 stage 2 draft decorators.

Output more detailed compiler performance information after building.

Emit a v8 CPU profile of the compiler run for debugging.

Allow importing helper functions from tslib once per project, instead of including them per-file.

Save .tsbuildinfo files to allow for incremental compilation of projects.

Include source code in the sourcemaps inside the emitted JavaScript.

Ensure that each file can be safely transpiled without relying on other imports.

Specify the JSX factory function used when targeting React JSX emit, e.g. 'React.createElement' or 'h'.

Specify module specifier used to import the JSX factory functions when using jsx: react-jsx*.`

A list of bundled library declaration files which describe the target runtime environment.

Print all of the files read during the compilation.

Specify the maximum folder depth used for checking JavaScript files from node_modules. Only applicable with allowJs.

Specify what method is used to detect whether a file is a script or a module.

List of file name suffixes to search when resolving a module.

Disable full type checking (only critical parse and emit errors will be reported).

Disable generating custom helper functions like __extends in compiled output.

Disable truncating types in error messages.

Avoid introducing anys inside your codebase when a type could be specified

Enable error reporting for codepaths that do not explicitly return in a function.

Disable adding 'use strict' directives in emitted JavaScript files.

Enforces using indexed accessors for keys declared using an indexed type.

Disable strict checking of generic signatures in function types.

Check side effect imports.

Raise an error when a function parameter isn't read.

Specify an output folder for all emitted files.

A set of locations to look for imports in

Disable erasing const enum declarations in generated code.

Preserve unused imported values in the JavaScript output that would otherwise be removed.

Enable color and formatting in TypeScript's output to make compiler errors easier to read.

Disable emitting comments.

Use the package.json 'exports' field when resolving package imports.

Specify the root folder within your source files.

Skip type checking .d.ts files that are included with TypeScript.

Create source map files for emitted JavaScript files.

Skip building downstream projects on error in upstream project.

Check that the arguments for bind, call, and apply methods match the original function.

When assigning functions, check to ensure parameters and the return values are subtype-compatible.

Check for class properties that are declared but not set in the constructor.

Disable reporting of excess property errors during the creation of object literals.

Set the JavaScript language version for emitted JavaScript and include compatible library declarations.

The file to store .tsbuildinfo incremental build information in.

Specify type package names to be included without being referenced in a source file.

Default catch clause variables as unknown instead of any.
