Compiler options

File path to the tsconfig.json file.

Whether to skip adding the source files from the specified tsconfig.json.

Skip resolving file dependencies when providing a ts config file path and adding the files from tsconfig.

Skip loading the lib files. Unlike the compiler API, ts-morph does not load these from the node_modules folder, but instead loads them from some other JS code and uses a fake path for their existence. If you want to use a custom lib files folder path, then provide one using the libFolderPath options.

The folder to use for loading lib files.

Manipulation settings

Whether to use an in-memory file system.

Optional file system host. Useful for mocking access to the file system.

Creates a resolution host for specifying custom module and/or type reference directive resolution.
