JavaScript Frameworks: Angular CLI and Webpack

JavaScript Frameworks Angular CLI and Webpack

A JavaScript framework is a JavaScript code library that comes up with the pre-written code functionality for developers for regular programming. The framework is a layout with a particular context and assists you in creating web applications within that context.

However, we can say JavaScript is a scripting language used to create and control dynamic web components that also need to be high on your list of front-end development skills to learn.

Hence, it’s a favorite for web developers both on the front and back end.

The dissimilarity between a framework and a library is a usual point of discussion in the software world. Experts have suggested that the difference between them can be blurry, but it is helpful to make the variance.

While a framework is a complete toolset that builds shapes and creates your website or application

On the other hand, a library is a collection of pre-written code chunks less about shaping your application and more about giving a use-as-needed library of features.

JavaScript frameworks, like most other frameworks, come up with some rules and policies. Using these, any developer can make complex applications faster and more efficient than building from scratch.

Though, the rules and guidelines help shape and organize your website or web application too!

Now we will be discussing some essential JavaScript frameworks: Angular CLI and Webpack.

JavaScript Frameworks: Angular CLI and Webpack

Angular CLI vs. Webpack: Differences between the two

What is Angular CLI?

Angular CLI, a command-line interface tool for Angular that you can use to initialize, build, scaffold, and prolong Angular applications directly from a command shell.

However, one can use the tool directly in a command shell or indirectly through an interactive UI such as Angular Console.

As Angular CLI is a command-line interface thus, it includes the functionality that Webpack provides.

Hence, we can say it is the official tool for initializing and operating with Angular projects. It helps you from out in the complex configurations and builds tools like TypeScript, Webpack, etc.

Although it uses Webpack to have all the packaging, importing, Browser Link, etc., you do not need to know how Webpack functions or how it needs to figure out to run in different environments or on other types of machines.

Angular CLI benefits

One can:

  • build a new Angular application
  • process a development server to preview the application during development
  • build the application for deployment to an environment of personal preference
  • perform Angular application’s end-to-end tests

What is Webpack?

If one is building a modern JavaScript application, the term “Webpack” is likely to be mentioned before.

Webpack, a static module bundler for JavaScript applications, takes all the code from your application and makes it reusable in a web browser.

Moreover, modules are reusable lumps of code built from your app’s JavaScript, node modules, and CSS styles that one can easily use in the website.

Webpack creates a dominion graph using the dependencies and permitting web developers to use a modular approach for web application building purposes.

Meanwhile, Webpack separates the code based on the app’s usage, the modular breakdown of responsibilities becomes much easier to manage, debug, verify, and test your code.

Webpack benefits

  • Support a multitude of plugins.
  • Provides code on-demand using the moniker code splitting.
  • Takes your non-core assets and converts them to dependencies for your application.
  • It gives JavaScript a module system.

Let us answer some questions related to Angular CLI and Webpack.

Why is Webpack used in Angular?

The advantages of Webpack in Angular are to perform many additional tasks and to support multiple nodes.

Hence, it is highly expansible via rules which allow developers to write custom tasks that they want to perform when bundling files together.

Therefore, the creation of an Angular application is on Webpack based tooling. Thus, Webpack is a popular module bundler tool, bundling application source code in suitable pieces for loading code from a server onto a browser.

Hence, an alternative to the System JS approach is practiced elsewhere in the documentation.

Is Webpack needed for Angular?

While the primary purpose of Webpack is to build multiple modules into a single file, it is not bound to only bundling source files.

Though it is hiding behind the Angular command-line tool, it may be applicable to modify the configuration of the Webpack during the development of an Angular application.

What is the importance of Angular Webpack so far?

Webpack is an open-source JavaScript module bundler. However, the primary purpose is to bundle JavaScript files for usage in a browser.

Moreover, it can also modify, pack, or combine just about any resource or asset. Hence, it uses modules with dominion and produces static assets representing those modules.

Which one is better: Angular CLI or Webpack?

Angular CLI and Webpack are fundamentally classified as “JavaScript Framework Components” and “JS Build Tools / JS Task Runners” tools, respectively.

Angular CLI and Webpack are both open-source tools. Webpack with 49.8K GitHub stars and 6.27K forks on GitHub appears to be more popular than Angular CLI with 21.9K GitHub stars and 7.02K GitHub forks.

As per the research, Webpack is faster than Angular-CLI, and it also removes unprocessed code.

Why is Angular CLI needed?

One can say, Angular CLI is much more than just creating an Angular project. However, one can use that to develop components, services, directives, and more.

Also, it supports building, serving, testing, etc. CLI itself is something to learn about, and it makes the Angular development workflow much simpler and faster.


Though one doesn’t need a JavaScript framework now and then, frameworks are helpful for developers with less experience to know the working of web platforms.

Between Angular CLI vs. Webpack, Angular CLI is, at the very least, a great starting point. Hence, it lets you focus on the logic of your app.

Angular CLI is, at the very least, a great starting point. However, it lets you focus on the logic of your app. However, be aware of its built-in limitations — abstraction and simplification.

In case you need to do anything uncommon, the chances are that you will need to switch to an Angular CLI.
