Why use Webpack as your next dev tool

Webpack is a static module bundler for JavaScript applications — it takes all the code from your application and makes it usable in a web browser. It can take care of bundling alongside a separate task runner. Webpack applies automatic transformations on your working files to make them into production files that are more useful for your end-user. Those transformed files are copies, and they go to a different folder, so the original files are never modified on this process, and stuff keeps tidy. 


If you're building a complex front-end application with many non-code static assets such as CSS, images, fonts, etc., Webpack will significantly benefit you. Here are a few reasons why you should choose Webpack over the competition.


Module Reliability

The smallest project you can with Webpack consists of input and output. The process starts from user-defined entries. The entries themselves are modules, and they can point to other modules through imports. When a project is bundled in Webpack, it traverses the imports, making a dependency graph of the project, and then generates an output based on configuration.


Configuration Driven

Webpack relies on the configuration. Its configuration model can feel a bit overwhelming at times as the configuration file can appear monolithic. It can be challenging to understand what webpack is doing unless you know the ideas behind it. Taming Webpack configuration is one of the best ways to get the best result using Webpack.


Code Splitting

Webpack's bundling capabilities are extensive. Another one is code splitting; Webpack lets you split code in various ways. One can even load code dynamically as the application gets executed. This enhances performance; even small applications can benefit from Webpack code-splitting, as it allows users to get something usable in their hands quickly. 


Asset Hashing

Webpack lets you inject a hash into each bundle name, for example, app.e647dgy.js. This is to invalidate bundles on the client's side as changes are made. Bundle-splitting allows the client to reload only a small part of the data in the ideal case.

 

Webpack comes with a significant learning curve. However, it's a tool worth learning, given how much time and effort it can save over the long term.
