What it does

The pull-request updates the use of @theia/compression-webpack-plugin (an outdated fork) to it's upstream counterpart, since the former included security vulnerabilities.

The cache is now a configuration option directly from webpack, and was removed as part of [email protected].

How to test

1. confirm that executing yarn audit --level=high does not yield results for compression-webpack-plugin
2. confirm that the build is successful, and the generated webpack configuration is correct (examples/browser/gen-webpack.config.js)
3. confirm that compression works examples/browser/lib/ should contain *.gz compressions such as bundle.js.gz
4. confirm with compression off the *.gz files are not present

The dependency update looks good to me 👍

• The dependency does not appear in the audit list anymore.
• Files continue to be served using a compressed format. (content-encoding: gzip)
• No additional build/bundling issues, Theia runs normally.
