Implement task #4 - Add typescript

To implement the task and add TypeScript to the project, we need to perform the following steps:

1. Add TypeScript as a dependency in the package.json file:

   "devDependencies": {
    "typescript": "^4.0.3"
   }

2. Create a tsconfig.build.json file with the recommended TypeScript configuration for Nest.js:

   {
    "extends": "./tsconfig.json",
    "include": ["src", "test"],
    "exclude": ["node_modules", "**/*.spec.ts"]
   }

3. Update the tsconfig.json file to include the "baseUrl", "outDir", and "paths" options:

   {
    "compilerOptions": {
      "baseUrl": "./src",
      "outDir": "./dist",
      "paths": {
        "*": [
          "./node_modules/*",
          "./src/*"
        ]
      }
    }
   }

4. Update the package.json file to add the scripts for building and running the TypeScript code:

   "scripts": {
    "start": "node dist/main.js",
    "build": "rimraf dist && tsc -p tsconfig.build.json",
    "dev": "ts-node-dev --transpile-only --ignore-watch node_modules src/main.ts"
   }

5. Update the app.module.ts file to use the .ts extension:

   import { Module } from '@nestjs/common';
   import { AppController } from './app.controller';
   import { AppService } from './app.service';
   
   @Module({
    imports: [],
    controllers: [AppController],
    providers: [AppService],
   })
   export class AppModule {}
