Convert your tsconfig paths to jest `moduleNameMappers`.  

This introduces many bug fixes and improvements to [archived](https://github.com/ryohey/tsconfig-paths-jest) [tsconfig-paths-jest](https://www.npmjs.com/package/tsconfig-paths-jest) package.  

## Usage

In your `jest.config.js` file:  

```javascript

const getJestMappersFromTSConfig = require('tsconfig-paths-jest-mapper');

const moduleNameMapper = getJestMappersFromTSConfig();

module.exports = {

  moduleNameMapper,

  // ... other configs

}

```

It assumes you have tsconfig besides your `jest.config.js` file.  

You can also provide the path to your tsconfig if it is in a non-standard location:  

```javascript

const path = require('path');

const getJestMappersFromTSConfig = require('tsconfig-paths-jest-mapper');

const tsconfigPath = path.resolve(__dirname, '../../tsconfig.json');

const moduleNameMapper = getJestMappersFromTSConfig(tsconfigPath);

module.exports = {

  moduleNameMapper,

  // ... other configs

}

```

## Options

- __startsWith:__ ensures that all the replaced paths (keys in the tsconfig) happen at the beginning of the path. `true` by default.
