How To Use Custom Webpack Configurations with Angular CLI Builders

Learn how to create a custom webpack config inside an Angular project using CLI Builders. This example will reduce the file size of a library.

The Angular CLI can create a new Angular project and it will handle the webpack configuration. However, there are situations where you will want to add custom webpack functionality.

For the purposes of this article, you will learn how to use the moment.js library and remove unused locales to create a smaller bundle size.

Note: moment.js is a popular library for handling date and time. However, the current project status suggests that there may be other libraries with modern approaches that may suit your project better depending on your target audience. For educational purposes in reducing bundle sizes, this article will continue to use moment.js.

In this article, you will take an existing Angular CLI-generated project and use @angular-builders/custom-webpack for a custom webpack configuration.

Install Angular - Angular Environment Setup Process

Angular is a TypeScript based framework that works in synchronization with HTML, CSS, and JavaScript. To work with angular, domain knowledge of these 3 is required.

  1. Installing Node.js and npm
  2. Installing Angular CLI
  3. Creating workspace
  4. Deploying your First App

In this article, you will get to know about the Angular Environment setup process. After reading this article, you will be able to install, setup, create, and launch your own application in Angular. So let’s start!!!

Angular environment setup

Install Angular in Easy Steps

For Installing Angular on your Machine, there are 2 prerequisites:

  • Node.js
  • npm Package Manager
Node.js

First you need to have Node.js installed as Angular require current, active LTS or maintenance LTS version of Node.js

Download and Install Node.js version suitable for your machine’s operating system.

Npm Package Manager

Angular, Angular CLI and Angular applications are dependent on npm packages. By installing Node.js, you have automatically installed the npm Package manager which will be the base for installing angular in your system. To check the presence of npm client and Angular version check of npm client, run this command:

  1. npm -v

Installing Angular CLI

  • Open Terminal/Command Prompt
  • To install Angular CLI, run the below command:
  1. npm install -g @angular/cli

installing angular CLI

· After executing the command, Angular CLI will get installed within some time. You can check it using the following command

  1. ng --version

Workspace Creation

Now as your Angular CLI is installed, you need to create a workspace to work upon your application. Methods for it are:

  • Using CLI
  • Using Visual Studio Code
1. Using CLI

To create a workspace:

  • Navigate to the desired directory where you want to create your workspace using cd command in the Terminal/Command prompt
  • Then in the directory write this command on your terminal and provide the name of the app which you want to create. In my case I have mentioned DataFlair:
  1. Ng new YourAppName

create angular workspace

  • After running this command, it will prompt you to select from various options about the CSS and other functionalities.

angular CSS options

  • To leave everything to default, simply press the Enter or the Return key.

Angular Sass: How To Use Sass In Angular 9 Tutorial

Angular supports Sass, CSS, and Less to style global application styles as well as component styles. Angular components styles have an effective CSS encapsulation mechanism that assures any component CSS is local to the component and does not globally alter any styles.

Angular Sass Example

Why use Angular Sass? Well!! Sass (Syntactically Awesome Style Sheets) is an extension of CSS that allows you to use things like variables, nested rules, inline imports, and more. It also supports you to keep things organized and enables you to create style sheets faster.

In short,  Sass is a CSS preprocessor, which combines unique features such as variables, nested rules, and mixins (sometimes referred to as syntactic sugar) into regular CSS. The main object of Sass is to make the CSS coding process more comfortable and more efficient.

Sass is compatible with all versions of CSS. When working with the Angular CLI, the default stylesheets have the .css extension. We are using Angular CLI 8. So, if you have not used previously, then please upgrade your  CLI version. We will use the Bootstrap 4 Framework for this demo and see how we can configure the Sass in our Angular 9 application.

Useful command of Angular CLI

I made a small list of commands which use a lot in Angular CLI and I want to share my list with you.

First of all, we need to install Angular CLI.

npm install -g @angular/cli

This command we need to write in terminal or console.

When cli is installed we need to create our first project:

ng new name-of-project

This command will create an empty project for us. If want to use in our project SCSS files instead of CSS,we must write:

ng new name-of-project --style=scss

After project creation, we need to install all packages which contains in packege.json.

npm intall

Now packages are installed and we can run our project:

ng serve

If we want to run and open our project in browser we should use:

ng serve --open 

By default Angular run project on port:4200, if we want to set another port:

ng serve --port=4222

Also we can use both those option in one command:

ng serve --open --port=4222 

Setting the watch option false will stop automatic rebuilds when you change code:

ng serve --watch=false

When running ng serve, the compiled output is served from memory, not from disk. This means that the application being served is not located on disk in the dist folder.

ng serve --poll 1000

Sometimes could be very useful to build project in production mode:

ng build --prod

Also we could use Ahead of Time Compilation which compiles your app at build time:

ng build --prod --aot

It is time to start developing our project, that means we need to create a new component, class, module, or something else. Angular CLI can help us with that:

ng generate component name-of-component

This Is How angular-cli/webpack Delivers Your CSS Styles to The Client

Have you ever wondered how is it possible to import CSS into JavaScript files? In this article I’ll show you how Webpack does it by transforming your CSS styles into JavaScript.

This is expected but the real question is how does Angular-CLI does it? Actually the styles are packaged and delivered to the client by webpack. Angular-CLI uses webpack under the hood and only configures it.

In this article I will show step-by-step how it’s done using webpack. The information presented here will be useful for anyone using webpack, not just Angular-CLI.
