What is the role and main functions of the tsconfig.json file in a TypeScript project?

The tsconfig.json file in a TypeScript project serves as the configuration file for the TypeScript compiler. It specifies compilation options and project settings.

Main functions:

• Defines root files and folders (files, include, exclude).
• Configures compilation options (compilerOptions), such as:
  • target — the JavaScript version to compile to.
  • module — module system (CommonJS, ES6, etc.).
  • strict — enable strict type checking.
  • outDir — folder for compiled files.
• Allows managing compiler behavior and integration with editors and build tools.

Example of a minimal tsconfig.json:

{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "strict": true,
    "outDir": "dist"
  },
  "include": ["src/**/*"]
}
