Intro to TypeScript - EmergentWorks

Hi! This is the companion code repository for my Intro to TypeScript EmergentWorks workshop.

See the slides here!

See JoshuaKGoldberg/typescript-intro-emergentworks-react#1 for results and raw notes from the workshop! ⚒

Online Resources

• typescriptlang.org has complete docs on using the TypeScript language.
• typescriptlang.org/play has an online playground you can write TS code in.
• code.visualstudio.com describes installing and using VS Code (optional).

Setup

Run these somewhere on your computer to download this repository and install its requirements:

git clone https://github.com/JoshuaKGoldberg/typescript-intro-emergentworks
cd typescript-intro-emergentworks
npm i

You can then open the folder in your editor. For example, with VS Code:

code .

Running TypeScript Snippets

It's generally easiest to install TypeScript globally:

npm i -g typescript

We recommend you then run TypeScript in "watch" mode on individual code examples by providing it the -w flag and a path to the example. For example, to start TypeScript running on the first code example:

tsc -w src/1

Alternately, if you'd prefer not to install TypeScript globally, you can use it as an already-installed dependency of this repository with the npm run compile command:

npm run compile -- src/1 -w
# Alternately: yarn compile src/1 -w
