What are @nx/js's main functionalities?

Building JavaScript Projects

This feature allows you to build JavaScript projects using the Nx build executor. The code sample demonstrates how to configure a project named 'myApp' with build options.

module.exports = {
  projects: {
    myApp: {
      root: 'apps/my-app',
      sourceRoot: 'apps/my-app/src',
      projectType: 'application',
      targets: {
        build: {
          executor: '@nx/js:build',
          options: {
            outputPath: 'dist/apps/my-app',
            main: 'apps/my-app/src/main.ts',
            tsConfig: 'apps/my-app/tsconfig.app.json'
          }
        }
      }
    }
  }
};

Testing JavaScript Projects

This feature allows you to test JavaScript projects using the Nx test executor. The code sample demonstrates how to configure a project named 'myApp' with test options.

module.exports = {
  projects: {
    myApp: {
      root: 'apps/my-app',
      sourceRoot: 'apps/my-app/src',
      projectType: 'application',
      targets: {
        test: {
          executor: '@nx/js:test',
          options: {
            jestConfig: 'apps/my-app/jest.config.js',
            passWithNoTests: true
          }
        }
      }
    }
  }
};

Managing Dependencies

This feature allows you to manage dependencies and lint JavaScript projects using the Nx lint executor. The code sample demonstrates how to configure a project named 'myApp' with lint options.

module.exports = {
  projects: {
    myApp: {
      root: 'apps/my-app',
      sourceRoot: 'apps/my-app/src',
      projectType: 'application',
      targets: {
        lint: {
          executor: '@nx/js:lint',
          options: {
            lintFilePatterns: ['apps/my-app/**/*.ts']
          }
        }
      }
    }
  }
};

Compared to @nx/js, Webpack is more focused on the bundling aspect and does not provide the same level of project management and dependency management features.

jest

Jest is a delightful JavaScript testing framework with a focus on simplicity. It works with projects using Babel, TypeScript, Node.js, React, Angular, Vue.js, and Svelte. Compared to @nx/js, Jest is specifically focused on testing and does not provide build or dependency management features.

eslint

ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. It helps in maintaining code quality and consistency. Compared to @nx/js, ESLint is specifically focused on linting and does not provide build or testing features.
