This is a simple skeleton to use typescript and scss with webpack.
Run npm install
then npm run build
then npm run dev
A development server should open at http://localhost:8080/
To stop the server just run CTRL+c and hit Y then enter in the command line.
After the project is running, you can then change code in the src folder. Either the index.ts file or main.scss file. Any changes to these files will automatically rebuild the project and changes should be seen live in the browser.
