Therefore, it seems that a warning is displayed.

Change the streaming server to use babel-preset-env as well as asset compilation.

Processing of ES Modules is executed by Webpack.
Don't have to do it on Babel side.

* Add plugin for test

Use ES Class Fields & Static Properties (currently stage 2) for improve class outlook.

Added babel-plugin-transform-class-properties as a Babel plugin.

There are some dependencies that are no longer needed anymore.
As a result, it took more time to install the package than necessary.

I want to delete them and shorten the installation time.
