From there, it determines which other modules and libraries that entry point depends on (directly and indirectly) and includes them in the graph until no dependency is left. Entry: the entry point is the module that webpack uses to start building its internal dependency graph.Webpack has some main concepts which we need to understand clearly before digging in its practical implementation. Now, to expand the above cursory overview, let’s explore the main concepts webpack uses. This can then be included in your HTML files.

“Statically” means that, when webpack builds its dependency graph, it doesn’t execute the source code but stitches modules and their dependencies together into a bundle. In this way, webpack statically traverses all modules to build the graph, and uses it to generate a single bundle (or several bundles) - a JavaScript file containing the code from all modules combined in the correct order.
A dependency graph describes how modules relate to each other using the references ( require and import statements) between files.
Under the hood, it relies on a dependency graph. In a particular project, webpack treats all files and assets as modules. What Is Webpack?Īs its core, webpack is a static module bundler. Note: in this tutorial I’ve used webpack 5.9.0. In this tutorial, I’ll introduce all the core concepts to help you get started. However, webpack is worth learning and can save considerable time and effort in the long run. Although it has good documentation, it can be daunting for novices, and it has a steep learning curve. When using webpack for the first time, it can be difficult to understand how it works and how it should be used. As a result, we need to utilize additional time and effort to learn, understand and use these tools correctly. Often, though, such tools add an extra layer of complexity into the stack. Nowadays, we’re forced to use many accessory tools to facilitate, speed up and optimize our web development workflow.
