- Built-in Callbacks: FSCSS provides onSuccess and onError hooks for better control over style execution results. Use them to log, debug, or respond to runtime style application.
- Error Reporting: Errors are caught and reported through a clean callback interface, making debugging straightforward and user notifications possible.
- Maintainable Structure: The exec() method uses named parameters, improving readability and maintainability—especially useful for scaling or integrating multiple stylesheets. 🧪 Example: Dynamically Load a Remote FSCSS File with Debugging
import { exec } from "https://cdn.jsdelivr.net/npm/fscss@1.1.6/e/xfscss.min.js";
const DEBUG = true;
function applyFSCSS({ type, content }) {
exec({
type,
content,
onSuccess: (styleElement) => {
if (DEBUG) console.log("✅ FSCSS applied:", styleElement);
},
onError: (error) => {
console.error("❌ Failed to apply FSCSS:", error);
alert("⚠️ Could not load styles. Please try again later.");
}
});
}
applyFSCSS({
type: "URL",
content: "styles/style.fscss"
});
