tsc CLI Options

Show all compiler options.

Ignore the tsconfig found and build with commandline options and files.

Print names of files that are part of the compilation and then stop processing.

Compile the project given the path to its configuration file, or to a folder with a 'tsconfig.json'.

Print the compiler's version.

Build one or more projects and their dependencies, if out of date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

Do not allow runtime constructs that are not part of ECMAScript.

Interpret optional property types as written, rather than adding undefined.

Print files read during the compilation including why it was included.

Ensure that casing is correct in imports.

Generates an event trace and a list of types.

Specify emit/checking behavior for imports that are only used for types.

Include sourcemap files inside the emitted JavaScript.

Require sufficient annotation on exports so other tools can trivially generate declaration files.

Specify what JSX code is generated.

Specify the JSX Fragment reference to use for fragements when targeting React JSX emit, e.g. 'React.Fragment' or 'Fragment'.

Make keyof only return strings instead of string, numbers or symbols. Legacy option.

Enable substitution of default lib files with custom ones.

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.

Rewrite .ts, .tsx, .mts, and .cts file extensions in relative import paths to their JavaScript equivalent in output files.

Allow multiple folders to be treated as one when resolving modules.

Skip type checking all .d.ts files.

Sets the root path for debuggers to find the reference source code

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.
