Simple Wizard Stepper for your Angular Web Apps

A Series of Web Components that you can create in Angular and avoid having to import a whole library for it. In this post I’ll be creating a simple wizard stepper for your Angular Web Apps and PWAs (Progressive Web Apps), just using “vanilla” Angular components and services in a way you can consolidate your views while delivering great user experiences.

_Dependencies: _Angular CLI

Let’s build us ourselves a cool, simple and flexible wizard stepper component in Angular while at the same time we learn some important concepts about:

Creating encapsulated, decoupled components that communicate with one another seamlessly
Using services to enable inter-component communication
Using the Flexbox Model to style the components in a flexible, responsive way

Let’s start!

Creating the Project

Go ahead and create the project via the Angular CLI by using the command

ng new simple-wizard-stepper

Select YES on adding Angular Routing and pick SCSS as your stylesheet format at the prompts provided during project creation.

I’m gonna be using a slick Google Font for this project and also I’ll be using some Material Icons for Web by referencing them from a CDN. Place the links below inside of the tag of the project’s index.html. We’ll show how to use them later.

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

<link href="https://fonts.googleapis.com/css2?family=Alata&display=swap" rel="stylesheet">

Your app’s main index.html should look like this:

<!DOCTYPE html>
	<html lang="en">
	  <head>
	    <meta charset="utf-8" />
	    <title>Angular</title>
	    <base href="/" />
	    <link
	      href="https://fonts.googleapis.com/css2?family=Pacifico&display=swap"
	      rel="stylesheet"
	    />
	    <meta name="viewport" content="width=device-width, initial-scale=1" />
	    <link rel="icon" type="image/x-icon" href="favicon.ico" />
	  </head>

	  <body>
	    <app-root></app-root>
	  </body>
	</html>

At the root of the project, inside the src/app folder, I’ll be creating several directories for better project structure. I’ll create directories called components, models, pages and services. Your structure should look as follows (from the src root):

- src
  - app
    - components
    - models
    - pages
    - services
