Webpack how to build production code and how to use it

Question

I am very new to webpack, I found that in production build we can able to reduce the size of overall code. Currently webpack builds around 8MB files and main.js around 5MB.

Answer 1

You can add the plugins as suggested by @Vikramaditya. Then to generate the production build. You have to run the the command

webpack -p --config ./webpack.production.config.js

The -p tells webpack to generate a production build. You have to change the build script in package.json to include the production flag.
