Prerequisites for Participants:

• Basic understanding of TypeScript

Workshop Plan

We'll be running from 9:00 - ??:??.

• ??:??: First session
• ??:??: Coffee Break
• ??:??: Second session

System Requirements

• git v2.14.1 or greater
• NodeJS v18.x or greater
• npm v8.5.0 or greater

All of these must be available in your PATH. To verify things are set up properly, you can run this:

git --version
node --version
npm --version

Setup

After you've made sure to have the correct things (and versions) installed, you should be able to just run a few commands to get set up:

git clone https://github.com/danduh/workshop-ts.git
cd workshop-ts
npm install

Test it up

To make sure that everything works fine:

npm run ts

# In your output you will see something similar to:
1 [@log] Compilation time
1 [@log] Compilation time
2 [@log] Method primeMethodRecurcion was fired
3 [@log] Arguments passed to primeMethodRecurcion => 10000
4 [@log] starting execution of primeMethodRecurcion method
5 [@log] Results 1229
6 [@log] Method primeMethodRecurcion was completed

That's it! You'll now have all the dependencies you need to work through the workshop exercises.
