Scala.js and Vite example

This example project shows how to use Vite together with Scala.js.

Getting started

You need to:

• Install the javascript libraries:

npm install

• Run the Vite Dev Server:

npm run dev

• Start rebuilding the Javascript code on every source change (in another terminal):

./mill -w publicDev

Production build

You need to run:

npm run build

Now you can find your production build in the dist folder.

Testing

You can run the tests with:

./mill __.testForked

Running specific tests

To test the dom we use jsdom. jsdom doesn't support modules so we need building the app with Vite first. This is done in project/vite.mill.scala

Since this is slower than just building the tests with Scala.js we define two separate test suites.

With:

./mill test-pure

You run the pure test suite which doesn't have access to the dom,

With:

./mill test-dom

You can run tests that require the dom against jsdom.
