By default, the aurelia vite plugin generates aliases to dev packages for better experience during development. It'll detect development mode based on the mode config from vite. You can also override using useDev options, in case there needs to be clarity into some behavior of the applications:
import { defineConfig } from 'vite';
import aurelia from '@aurelia/vite-plugin';
export default defineConfig({
...,
plugins: [aurelia({ useDev: true })], // always use dev bundles
});
