Build

Use the following commands to download the LiaScript source-code and to build it locally.

git clone https://github.com/liascript/liascript

cd liascript

npm i

npm run watch  # develop in watch-mode

npm run build  # build to dist

After your first build, you can run the following commands, this will download additional elm-patches and apply them:

git submodule update --init --recursive

cd patches

make

cd .. # go back

rm -rf elm-stuff .parcel-cache # remove all cached stuff

npm run build # force an entire rebuild of the project

This will apply the following four patches:

elm-break-dom: allows browser extensions such as screen-readers to change the nodes of the app, without crashing the app
elm-patch/url: enables the file-protocol, which is only required when building Desktop-apps
elm-patch/dom: enable onclick events as well as innerHTML
Dexie: this will allow only LiaScript to access indexedDB, which increases the security, by restricting the access. This way information about user states, visited courses, etc. cannot be leaked or spied by other JavaScript modules.

Preview

If you want to add a preview-link for the course to your site, simply add the following script to the head of your website and place the custom webcomponent preview-lia anyone in your document, with src pointing to your LiaScript course.

<html>
  <head>
    ...
    <!-- add preview-lia tag support to display all course related information -->
    <script
      type="text/javascript"
      src="https://liascript.github.io/course/preview-lia.js"
    ></script>
    ...
  </head>
  <body>
    ...
    <preview-lia
      src="https://raw.githubusercontent.com/liaScript/docs/master/README.md"
    ></preview-lia>
    ...
  </body>
</html>
