How to start this nodejs (hapijs ) API project ,alone without docker?

I am working on a Nodejs -Hapijs project. This project have a “Make” file to start the

project, but the project will start in docker , I can not debug the API also the project

will start as a whole ( API + UI ) in docker.

I tried to start the API independently but could not do it.

Here is the API file structure , package.json file Image od API folder structure

"scripts": {
    "build": "npm run clean && .tsc",
    "clean": "rm -rf ./dist",
    "lint": "tslint -p ./tsconfig.json -c ./tslint.json",
    "lint-serve": "npm run lint & npm run serve",
    "serve": "node ./index.js",
    "start": "if [[ $NODE_ENV == "production" ]]; then npm run serve; else npm run watch; fi",
    "test": "jest --verbose --coverage --detectOpenHandles",
    "test:watch": ".jest --verbose --watchAll",
    "watch": "tsc-watch --onSuccess "npm run lint-serve""

This is the package.json file (scripts part).This project is written in typescript, I can give you more required details , I am not sure what information I should add other than this .

THINGS I HAVE TRIED

1. npm start

Any help
