This are my notes of this TypeScript tutorial https://www.youtube.com/watch?v=BwuLxPH8IDs

setup

• install node js
• install TS via npm: npm install -g typescript

Compile ts to js:

tsc app.ts

watchmode for single file:

tsc app.ts -w  // watchmode for single file

watchmode for all files:

tsc --init
tsc -w

Server for localhost:

npm init
npm install --save-dev lite-server
npm start

Settings:

• sourceMap: set to true if you want to debug ts code in browser
• outFile: where to save js code
• rootDir: where the ts code is located
• noEmitOnError: if true and ts code has errors, then no js code is generated
