TypeScript Environment Setup

This setup is suited for Fastify, it can be adjusted for other frameworks.

npm init -y
npm i -D @types/node @tsconfig/node18 nodemon ts-node typescript
npm i fastify @sinclair/typebox

tsconfig.json:

{
  "extends": "@tsconfig/node18/tsconfig.json",
  "compilerOptions": {
    "rootDir": "src",
    "outDir": "dist",
  }
}

package.json scripts:

"scripts": {
    "start": "nodemon index.ts",
    "build": "tsc --project ./"
}

Or, if the app is not supposed to run continuously:

"scripts": {
    "start": "ts-node .src/index.ts",
    "build": "tsc --project ./"
}
