Setup
In this walkthrough we will build a small library that can be used in other projects. The goal of
this walkthrough is to learn the CodeCoupler Webpack development environment
@codecoupler/cc-webpack
that will be used also in all following walkthroughs.
Please make sure that you have installed the following extensions in your Visual Code environment:
Start your project in a new folder and create a folder named walkthrough-lib
(later on we will
create folders for ui, api and setup). Please open now the folder walkthrough-lib
in Visual Code,
open a terminal and initialize the project with:
1 2 3 |
|
Go to the file index.js
in the folder src
and put your first line of code:
src/index.js
1 |
|
Please start now watching your changes with npm start
. This will start browser and all
modifications in your code from now will reload the page automatically. From now on we will call
this terminal with the running server the watching terminal. You can cancel the server with
Ctrl+C.
You should see now the ingenious sentence "Hello World" in a browser window. Now add an exclamation mark at the end and save the file again:
src/index.js
1 |
|
In the watching terminal you will see a new compilation starting, then the browser reloads and you will see the changes.
