Deprecation Warning

[fabianmarcus]

When I build my app with Webpack I get this deprecation warning:

(node:86841) [DEP_WEBPACK_COMPILATION_OPTIMIZE_CHUNK_ASSETS] DeprecationWarning: optimizeChunkAssets is deprecated (use Compilation.hooks.processAssets instead and use one of Compilation.PROCESS_ASSETS_STAGE_* as stage option) (Use node --trace-deprecation ... to show where the warning was created)

Can we get rid of this?

Agree. It's coming from last-call-webpack-plugin.

As updates are pending, possible solution could be to use css-minimizer-webpack-plugin package.

"Just like optimize-css-assets-webpack-plugin but more accurate with source maps and assets using query string, allows to cache and works in parallel mode."
