Simple Ionic 6 + ViteJS app

This repository contains a simple React application that uses ViteJS template and Ionic 6 (RC2). It demonstrates issue with vite serve (as of November 16, 2021).

Creation steps

I tried to stay as close to the original ViteJS template as possible:

# use ViteJS's "react-ts" template
cd /work/directory
yarn create vite ionic-simplevitejs --template react-ts

# add Ionic 6 RC2
cd ./ionic-simplevitejs
yarn && yarn add --dev @ionic/react@next

# open in editor
# - add "Hello World" page to "App.tsx"
# - remove unused files
# - simplify "main.tsx"
# - fix TypeScript build issue ("skipLibCheck" in "tsconfig.json")
code .

Development mode

When running the web application in development mode, everything works as expected:

# start ViteJS development server
yarn dev

The DOM contains all the Ionic elements, as expected:

Production mode

However, when I run the web application in production mode (ViteJS's preview), the page is not rendered correctly:

# build distribution files and start ViteJS preview server
yarn build && yarn serve

The DOM explains why the page doesn't look right -- all ion-... elements are replaced with tagname elements, and shadow DOM nodes are missing:
