npm install typescript -D -E

  "scripts": {
    "tsc": "tsc"
  }

This generates the code JS for prod

npm run tsc -- --init

npm install @types/express -D -E

npm install ts-node-dev -D -E

  "scripts": {
    "dev": "ts-node-dev src/index.ts"
  }

npm install ts-standard -D -E

  "scripts": {
    "lint": "ts-standard"
  }

and add in the packa.json:

  "eslintConfig": {
    "parserOptions": {
      "project": "./tsconfig.json"
    },
    "extends": [
      "./node_modules/ts-standard/eslintrc.json"
