How to Create Custom Loading Spinners in AngularJS

Loading spinners are a simple yet effective way to improve the user experience on your website or app. They provide visual feedback that content is being loaded, preventing users from wondering if the page is stuck or broken. Whether you’re building a web app, mobile app, or website, implementing loading spinners can significantly enhance your interface’s polish and professionalism.

In this guide, I’ll walk you through how to implement loading spinners using modern, efficient methods. Let’s dive in!

What is a Loading Spinner?

A loading spinner is an animated graphic that typically displays a rotating circle or dots to indicate that a process is ongoing. This small visual cue helps manage user expectations during load times, making waiting periods feel shorter and less frustrating.

Why Use Loading Spinners?

• Improves User Experience: Keeps users informed that content is loading.
• Prevents Premature Actions: Stops users from clicking elements before they’re ready.
• Enhances Perceived Performance: Even slight waiting feels better when users see a spinner.

How to Implement Loading Spinners

1. Using Pure CSS Spinners

One of the most lightweight and versatile ways to add a loading spinner is through CSS animations. This doesn’t require additional images or JavaScript libraries and is highly customizable.

Step-by-step:

HTML

CSS

css
.spinner {
width: 40px;
height: 40px;
border: 5px solid #f3f3f3; / Light grey /
border-top: 5px solid #3498db; / Blue /
border-radius: 50%;
animation: spin 1s linear infinite;
margin: auto; / Center horizontally /
}

@keyframes spin {
0% { transform: rotate(0deg); }
100% { transform: rotate(360deg); }
}

Explanation:

• The .spinner element is a circle created using borders.
• One border segment is colored differently to create the spinning effect.
• The spin animation rotates the element infinitely.

2. Using SVG Spinners

SVGs give you sharp, scalable spinners that look great at any size.

Example:

HTML

CSS

css
.spinner {
animation: rotate 2s linear infinite;
width: 40px;
height: 40px;
margin: auto;
}

.path {
stroke: #3498db;
stroke-linecap: round;
animation: dash 1.5s ease-in-out infinite;
}

@keyframes rotate {
100% { transform: rotate(360deg); }
}

@keyframes dash {
0% {
stroke-dasharray: 1, 150;
stroke-dashoffset: 0;
}
50% {
stroke-dasharray: 90, 150;
stroke-dashoffset: -35;
}
100% {
stroke-dasharray: 90, 150;
stroke-dashoffset: -124;
}
}

This method offers a smooth, modern look that works well in any resolution.

3. Using JavaScript Libraries and Frameworks

If you are using frameworks like React, Vue, or Angular, you can leverage community-built spinner components.

For example, in React:

jsx
import React from ‘react’;

function Spinner() {
return

;
}

You would still style .spinner with the CSS shown above, or use libraries like React Spinners for ready-to-use options.

Tips for Effective Loading Spinners

• Keep it Simple: Avoid overly complex animations that distract.
• Match Your Brand’s Colors: Customize the spinner color to your brand palette.
• Place Strategically: Center spinners or position them near the content area.
• Use Appropriate Size: Ensure the spinner is visible but not overwhelming.
• Combine with Text if Needed: Sometimes adding “Loading…” helps clarify.

Conclusion

Loading spinners are a small but crucial part of a seamless user experience. Whether you choose a simple CSS spinner, SVG animation, or a framework-specific component, implementing a loader ensures your users stay informed and engaged during waiting periods.

Remember to keep your spinners subtle, visually consistent, and optimized for performance. Happy coding!
