TRANSFORMATION NODE TYPESCRIPT CODE TO PRODUCTION CODE

Recommended for production using Nodejs Typescript, use Babel as an additional feature of the compiler and many plugins can be used, because the default Typescript compiler cannot be used to delete console.log for your production code if you imagine there are 100 console.log entered into different files. after dev development, it will be homework if you have to remove them one by one, try this method for production code Nodejs + Typecript.

//package.json
scripts: {
  "mkdir": "make-dir temp",
  "cpf": "cp -r src temp && cp server.ts temp",
  "del:temp": "rimraf temp",
  "del:dist": "rimraf dist",
  "compiler": "npm run mkdir && npm run cpf && babel --extensions '.ts' temp -d dist",
  "build": "npm run del:dist && npm run compiler && npm run del:temp"
}
