Description

Description

Currently, zeppelin-web uses Webpack for its build tools.

Webpack offers great features like webpack-dev-server hot module replacement, which significantly eases development by automatically updating the UI in response to code changes.

Unfortunately, it seems that hot module replacement isn’t working at the moment. This impacts the developer experience, especially on the frontend side.

We hope this issue gets resolved as soon as possible and look forward to welcoming new frontend contributors!

Reproduction

1. git clone latest code.

git clone https://github.com/apache/zeppelin.git

2. change directory to zeppelin-web

cd zeppelin-web

3. install dependencies

npm i

4. run dev mode

npm run dev

5. modify any codes you want to see the change (I'd recommend <H1/> simply)

1. move to zeppelin-web/src/app/home.html
2. change any html codes you can easily detect

6. you can check it doesn't update UI automatically. you should reload instead.
