This is my first time going through JavaScript and TypeScript for real.

I want to understand the workflows in creating, testing, and running web development code with TypeScript and NodeJS.

NOTE: These notes are NOT a replacement for watching the actual tutorial they were based on. These are just my personal notes and examples based on the 21-episode tutorial series (see below for more details).

1. After NodeJS is installed, run npm install -g typescript

1. Open a terminal
2. Run tsc {INPUT_FILE} [{OUTPUT_FILE}]

• Example: tsc sandbox.ts sandbox.js
• NOTE: If the {OUTPUT_FILE} arg is omitted, the output file will be the same name as the {INPUT_FILE}, but with a .js file extension.

If you're making frequent edits to your TypeScript files, and want them quickly compiled each time you save, you can pass in -w to the tsc (TypeScript Compiler)! Once finished, you can easily break out (Ctrl + C).

If you're using a folder structure (such as public/ and src/), and don't wish to enter a ton of commands to compile every .ts (TypeScript) file, and then manually drag them into the corresponding folders, use the following:

1. Open a terminal
2. Navigate (cd) into your project's root folder
3. Run tsc --init to generate the starting tsconfig.json file
4. Open the new tsconfig.json file
5. Set rootDir to ./src (for example)
6. Set outDir to ./public (for example)
7. Add "include": ["src"] so that it ignores anything OUTSIDE of the src folder
8. Now, run tsc (or tsc -w) and your files should automatically be done from the src to public directories

I am following a tutorial series of 21 episodes from here.

Their repository example can be found here.
