How to Setup Nodejs-Typescript

Install typescript

• Run the command to install the typescript package

npm install typescript --save-dev

• Run the command to initialize tsconfig.json - this file will contain your typescript settings more like typescript rules you want to allow/disallow for your project.

tsc --init

• Update the tsconfig.json file: specify the folder it will go to find the .ts file and tell it to exclude node_modules folder

  "include": ["src/**/*"],
  "exclude": ["node_modules"]

• Update the tsconfig.json file: Also specify the outDir value. Make sure to add build folder to gitignore

{
  ...
  "outDir": "build",/* Specify an output folder for all emitted files. */
  ...
}

• Install ts-node - allow node to use typescript

npm install -D ts-node
npm install -D tslib @types/node

Update Scripts

• First install nodemon

npm install -D nodemon

• Update the script

  "scripts": {
    ...
    "start": "npm run build && node build/index.js",
    "dev": "nodemon --exec ts-node src/index.ts",
    "build": "tsc"
    ...
  },
