The best way to add icons to a project is to use a dedicated icon library or design software.

Best way to manage icons in an Angular project, here's a breakdown of the top approaches — with their pros and when to use them:

---

✅ Option 1: Inline SVGs (Best for styling and accessibility)

✅ How:

<a href="https://twitter.com/yourcompany" target="_blank" aria-label="Twitter">
  <svg class="icon icon-twitter" aria-hidden="true">
    <use xlink:href="assets/icons/sprite.svg#twitter"></use>
  </svg>
</a>

Pros:

• Fully stylable with CSS (fill, stroke, hover, etc.)

• Better performance when using SVG sprites (one file, multiple icons)

• Accessible with aria-*

How to create sprite (optional):

Use a tool like SVGOMG or svg-sprite-generator to build a sprite file.

---

✅ Option 2: Use Angular Material Icons (if you're already using Angular Material)

✅ How:

<mat-icon fontSet="fa-brands" fontIcon="fa-twitter"></mat-icon>

With FontAwesome or custom fonts.

Pros:

• Easy integration with Angular Material

• Tons of available icons

• Dynamic theming possible

Setup:

npm install @fortawesome/fontawesome-free

Add to angular.json:

"styles": [
  "node_modules/@fortawesome/fontawesome-free/css/all.min.css",
  "src/styles.css"
]

---

✅ Option 3: Use SVG Icon Registry (MatIconRegistry) for Angular

This is more advanced and Angular-native.

Example:

In app.module.ts:

import { MatIconRegistry } from '@angular/material/icon';
import { DomSanitizer } from '@angular/platform-browser';

constructor(iconRegistry: MatIconRegistry, sanitizer: DomSanitizer) {
  iconRegistry.addSvgIcon(
    'twitter',
    sanitizer.bypassSecurityTrustResourceUrl('assets/icons/twitter.svg')
  );
}

And in template:

<mat-icon svgIcon="twitter"></mat-icon>

---

✅ Option 4: Continue Using <img src="..."> (Simple and safe)

Your current approach is:

<img src="assets/icons/twitter.svg" alt="Twitter" />

Pros:

• Very simple

• No setup required

• Works with asset pipeline

Cons:

• Less control over styles (can’t fill: red directly)

• Slightly heavier on DOM than inline SVG

Option 5:

 <div class="footer-socials">
      <a href="https://twitter.com/yourcompany" target="_blank" aria-label="Twitter">
        <img src="assets/icons/twitter.svg" alt="Twitter" />
      </a>
      <a href="https://linkedin.com/company/yourcompany" target="_blank" aria-label="LinkedIn">
        <img src="assets/icons/linkedin.svg" alt="LinkedIn" />
      </a>
      <a href="https://github.com/yourcompany" target="_blank" aria-label="GitHub">
        <img src="assets/icons/github.svg" alt="GitHub" />
      </a>
    </div>

✨ Recommended Best Practice

If you want full control, performance, and flexibility:

✅ Use inline SVGs or an SVG sprite system
✅ Optionally register them via Angular’s MatIconRegistry if using Angular Material

---

Example (your current HTML improved with inline SVG for styling):

<a href="https://twitter.com/yourcompany" target="_blank" aria-label="Twitter">
  <svg class="icon icon-twitter">
    <use xlink:href="assets/icons/sprite.svg#twitter"></use>
  </svg>
</a>

And in CSS:

.icon {
  width: 24px;
  height: 24px;
  fill: currentColor;
}
a:hover .icon {
  color: #1DA1F2; /* Twitter blue */
}
