  1. Firstly let's automate running the app.ts file using this script command by adding "start": "tsc app.ts && node app.js".
  2. Then execute the command tsc --init to initialize tsconfig.json file
  3. Previously we've used a trick to compile and run the ts code using script now we're going to do it in a separate way.
  4. Create 2 folders server and dist. Then move app.ts to server folder
  5. Please uncomment the outDir property and put "./dist""
  6. Just run tsc command in the console and see whether .js file is created inside dist folder.
  7. Then run npm i @types/node -D to add fs file sync as dependency and show js code generated for ES version.
  8. Change the "module": "ES2022" and see the result
  9. Always we have to run tsc and then node dist/app.js so let's define a script for this "start": "tsc && node dist/app.js"
  10. However, we have a simplified way to do this as well
  11. Then please use npm install ts-node -D to install ts-node.
  12. Then replace start script to "start": "ts-node server/app.ts"
  13. So, you'll not need the dist directory anymore.
