What is @nx/jest?

@nx/jest is a package that integrates Jest testing framework with Nx, a set of extensible dev tools for monorepos. It allows you to run and manage Jest tests efficiently within an Nx workspace.

What are @nx/jest's main functionalities?

Running Jest Tests

This configuration allows you to run Jest tests for multiple projects within an Nx workspace. The 'projects' array specifies the paths to the projects you want to include.

module.exports = {
  projects: ['<rootDir>/apps/my-app', '<rootDir>/libs/my-lib'],
};

Custom Jest Configuration

This sample shows how to create a custom Jest configuration for a specific project within an Nx workspace. It includes settings for transforming files, module file extensions, and coverage directory.

module.exports = {
  displayName: 'my-app',
  preset: '../../jest.preset.js',
  transform: {
    '^.+\\.[tj]sx?$': 'babel-jest',
  },
  moduleFileExtensions: ['ts', 'tsx', 'js', 'jsx'],
  coverageDirectory: '../../coverage/apps/my-app',
};

Running Tests with Nx CLI
