How It Works

class SSIcon extends HTMLElement {
  // Watch for attribute changes
  static get observedAttributes() {
    return ["icon", "thickness"];
  }

  constructor() {
    super();
    this.attachShadow({ mode: "open" });
  }

  // Re-render when attributes change
  attributeChangedCallback(name, oldValue, newValue) {
    if (name === "icon" || name === "thickness") {
      this.render();
    }
  }

  render() {
    const iconName = this.getAttribute("icon");
    const iconSvg = icons[iconName];
    // Inject SVG with custom thickness into shadow DOM
  }
}

customElements.define("ss-icon", SSIcon);

Styling

The component inherits color from parent:

.my-button {
  color: blue;
}
.my-button ss-icon {
  /* Icon will be blue */
}

Override size:

ss-icon {
  font-size: 24px; /* Icons scale with font-size */
}

ss-loader (Class-based Icons)

Location: src/ss-loader.js

Usage

<i class="ss ss-check"></i>
<i class="ss ss-arrow-left"></i>

How It Works

1. Initial Load: On DOMContentLoaded, finds all i.ss elements
2. Extract Icon: Looks for class starting with ss-
3. Inject SVG: Inserts SVG content into the element
4. Mark Loaded: Adds data-ss-loaded="true" to prevent reprocessing
5. Observe Changes: MutationObserver watches for new icons added dynamically

function replaceIcons() {

  const elements = document.querySelectorAll("i.ss");
  elements.forEach((el) => {
    if (el.dataset.ssLoaded) return; // Skip already processed
    
    const iconClass = classes.find(c => c.startsWith("ss-"));
    const iconName = iconClass.replace("ss-", "");
    const iconSvg = icons[iconName];
    
    if (iconSvg) {
      el.innerHTML = iconSvg;
      el.dataset.ssLoaded = "true";
    }
  });
}

// Watch for dynamically added icons
const observer = new MutationObserver((mutations) => {
  // Check for added nodes or class changes
  if (shouldUpdate) replaceIcons();
});

observer.observe(document.body, {
  childList: true,
  subtree: true,
  attributes: true,
  attributeFilter: ["class"]
});

Styling Class-based Icons

.ss {
  display: inline-block;
  width: 1em;
  height: 1em;
  vertical-align: middle;
}

/* Custom styling */
.ss-check {
  color: green;
  font-size: 2rem;
}

CSS-Only Icons (Alternative)

For environments without JavaScript, use the CSS-only approach:

<link rel="stylesheet" href="senangstart.min.css">
<i class="ss ss-check"></i>

The CSS uses mask-image with data URIs - no JavaScript required.

Extending the Components

Adding New Attributes to ss-icon

1. Add to observedAttributes array
2. Handle in render() method
3. Update tests in tests/ss-icon.test.js

Example: Adding a color attribute

static get observedAttributes() {
  return ["icon", "thickness", "color"];
}

render() {
  const color = this.getAttribute("color") || "currentColor";
  this.shadowRoot.innerHTML = `
    <style>
      :host { color: ${color}; }
      /* ... */
    </style>
    ${finalSvg}
  `;
}

Adding Animation Support

render() {
  const animate = this.hasAttribute("animate");
  this.shadowRoot.innerHTML = `
    <style>
      ${animate ? `
        @keyframes spin {
          from { transform: rotate(0deg); }
          to { transform: rotate(360deg); }
        }
        svg { animation: spin 1s linear infinite; }
      ` : ""}
    </style>
    ${finalSvg}
  `;
}
