• request warnings is from node-sass, nothing we can do: request has gone into maintenance mode. Maybe replace it. sass/node-sass#2851
• eslint-loader should be replaced with eslint-webpack-plugin Replace eslint-loader with eslint-webpack-plugin #30

Other warnings are also dependencies from node-sass or eslint-loader
