The less code you can send to the browser, the better. The concept of the tree shaking basically says so if you ' re not using some piece of code, then exclude it from the final bun Dle, even when that piece of code was exported from a module. Because ES6 modules is statically analyzable, Webpack can determine which of your dependencies is used and which is not . In this lesson, see how to take advantage of this awesome feature in

If you ' re going to use code splitting with Webpack 2, you'll need to make sure the browser have support for the ES6 Promise A Pi. This means is required to the support of an old browser, and you need to provide a polyfill. Polyfilling is relatively trivial to does with Webpack, but because Webpack itself depends on t

Often, you have dependencies which your rarely change. In these cases, you can leverage the Commonschunkplugin-automatically put these modules in a separate bundled file so T Hey can cached and loaded separately from the rest of your code (leveraging the browser cache much more effectively).The libaraies like ' Lodash ', ' jquery ' is required alomost all the projects and once download, and rarly change any more. So it would is a good idea to spreate those common libaries into a common vendor fi

When you had a dependency that had dependencies on global variables (like jQuery or Lodash) or assumes that's this Boun D window to, you can use the Imports-loaderto provide those dependencies explicitly.In case there are one dependency that we use the need lodash, but didn ' t includes Lodash as dependency.One-to-solve the problem is so we can include Lodash as denpedency in our application.Another-on-the-expose Lodash to the library, to-do, and you need to Install:NPM i-d Imports-loaderAdd to

You can fine tune several Webpack plugins to make your bundle as small as it can is for your specific application. However there is a few things you can does for pretty much every application to make it smaller and run faster. In this lesson we'll combine several webpack plugins to optimize things for a React application (this is also applicable F or non-react applications as well).First we need to modify t
