This is a project template for HSLayers-NG "full-featured" apps. It lives at https://github.com/hslayers/hslayers-template.
To create a new project based on this template use degit:
npx degit hslayers/hslayers-template hslayers-app
cd hslayers-app
Note that you will need to have Node.js installed.
Install the dependencies...
npm install
Note that if you have npm < 7 you need to install peer-dependencies manually.
...then start Angular dev server:
npm run dev
Navigate to localhost:4200. You should see your app running. Edit a component file in src, save it, and the page should reload with your changes.
Idea for this project template was taken from https://github.com/sveltejs/template-webpack. Kudos to its authors.
