When to use this skill

Use this skill when the user needs a custom UI (forms, charts, complex layouts) that cannot be achieved with standard VS Code UI elements.

How to use this skill

Register Command: First, create a command (using
```
vscode-feature-command
```
) that will open the webview.
Implement Webview Logic: In the command callback, create the panel.

Code Template

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
    let currentPanel: vscode.WebviewPanel | undefined = undefined;

    context.subscriptions.push(
        vscode.commands.registerCommand('extension.showWebview', () => {
            const columnToShowIn = vscode.window.activeTextEditor
                ? vscode.window.activeTextEditor.viewColumn
                : undefined;

            if (currentPanel) {
                // If we already have a panel, show it in the target column
                currentPanel.reveal(columnToShowIn);
            } else {
                // Otherwise, create a new panel
                currentPanel = vscode.window.createWebviewPanel(
                    'catCoding', // Identifies the type of the webview. Used internally
                    'Cat Coding', // Title of the panel displayed to the user
                    columnToShowIn || vscode.ViewColumn.One, // Editor column to show the new webview panel in.
                    {
                        enableScripts: true // Enable JS in the webview
                    }
                );

                currentPanel.webview.html = getWebviewContent();

                // Reset when the current panel is closed
                currentPanel.onDidDispose(
                    () => {
                        currentPanel = undefined;
                    },
                    null,
                    context.subscriptions
                );
            }
        })
    );
}

function getWebviewContent() {
    return `<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Cat Coding</title>
