Use this to avoid the declaration of the same module path aliases in `tsconfig.json` and `jest.config.js`. 


The package allows synchronizing Jest path aliases (`moduleNameMapper`) with your `tsconfig.json` configuration.

## Installation

`npm i jest-module-name-mapper -D`

## Usage

Set configuration in `jest.config.js`:

```

module.exports = {

  ...

  moduleNameMapper: require('jest-module-name-mapper')(),

};

```

If your `tsconfig.json` file is located in other directory then root, then you can set your own path to the file.

```

module.exports = {

  ...

  moduleNameMapper: require('jest-module-name-mapper')('/src/tsconfig.json'),

};

```
