TypeScript Project Analyzer

Build a utility that analyzes TypeScript configuration and type errors in a Create React App project.

Overview

Create a tool that checks if a Create React App project is properly configured for TypeScript and runs type checking to detect any errors. The tool should leverage Create React App's TypeScript integration features.

Requirements

Create a Node.js module that analyzes TypeScript configuration in Create React App projects:

1. Validates TypeScript Configuration

   • Checks if tsconfig.json exists in the project
   • Verifies TypeScript is installed as a dependency

2. Performs Type Checking

   • Runs TypeScript compiler to check for type errors
   • Collects type errors with file paths and messages

3. Returns Analysis Results

   • Returns an object with success status and error details
   • Includes the number of TypeScript files checked
   • Provides error information for debugging

Test Cases

• When run on a Create React App project with no TypeScript files, it reports that TypeScript is not configured @test
• When run on a Create React App project with TypeScript files and no errors, it reports success with the count of files checked @test
• When run on a Create React App project with TypeScript files containing type errors, it reports the errors with file names and error descriptions @test

API

/**
 * Validates TypeScript configuration and runs type checking
 * @param {string} projectPath - Path to the Create React App project directory
 * @returns {Promise<{success: boolean, filesChecked: number, errors: Array<{file: string, message: string}>}>}
 */
async function validateTypeScript(projectPath) {
  // Implementation here
}

module.exports = { validateTypeScript };

Dependencies { .dependencies }

create-react-app { .dependency }

Provides TypeScript integration with parallel type checking support, automatic tsconfig.json generation, and ForkTsCheckerWebpackPlugin for non-blocking type checks.
