Dynamic Vue Component Generation from Configuration

This challenge focuses on creating a system within a Vue.js application that can dynamically generate UI components based on a structured configuration object. This is a powerful technique for building flexible and scalable user interfaces, allowing for rapid prototyping and dynamic form generation or content rendering without hardcoding component structures.

Problem Description

Your task is to build a Vue.js component (or a set of components) that takes a JSON-like configuration object as input and renders the corresponding Vue components. This means you'll need to map configuration properties to Vue component types and their props.

Key Requirements:

• Component Mapping: You must establish a way to map string identifiers in the configuration to actual Vue component definitions.
• Prop Rendering: The generated components should receive the correct props as defined in the configuration.
• Nesting: The system should support nested components, where a parent configuration object can contain an array of child configurations.
• Text Content: Handle rendering of simple text content within components.

Expected Behavior:

Given a configuration object, the system should produce the correct Vue template structure with the appropriate components and props, and render them to the DOM.

Edge Cases to Consider:

• Unknown Component Types: What happens if the configuration specifies a component type that isn't mapped?
• Missing Props: What if a configured prop is not provided for a component?
• Empty Configuration: How should an empty or null configuration be handled?
• Data Types: Ensure correct handling of different data types for props (strings, numbers, booleans, arrays, objects).

Examples

Example 1: Simple Text and Button

Input Configuration:
{
  "type": "div",
  "children": [
    { "type": "p", "textContent": "Hello, World!" },
    { "type": "button", "props": { "onClick": "handleClick" }, "textContent": "Click Me" }
  ]
}

Expected Rendered Output (Conceptual Vue Template):
<div>
  <p>Hello, World!</p>
  <button @click="handleClick">Click Me</button>
</div>

Explanation:
A 'div' is rendered. Inside it, a 'p' tag with static text and a 'button' tag with text and an 'onClick' event handler are rendered.

Example 2: Nested Structures and Props

Input Configuration:
{
  "type": "form",
  "props": { "name": "registrationForm" },
  "children": [
    {
      "type": "input",
      "props": { "type": "text", "label": "Username", "modelValue": "" }
    },
    {
      "type": "input",
      "props": { "type": "password", "label": "Password", "modelValue": "" }
    },
    {
      "type": "button",
      "props": { "type": "submit" },
      "textContent": "Register"
    }
  ]
}

Expected Rendered Output (Conceptual Vue Template):
<form name="registrationForm">
  <input type="text" label="Username" v-model="formData.username" />
  <input type="password" label="Password" v-model="formData.password" />
  <button type="submit">Register</button>
</form>

Explanation:
A 'form' element is rendered with a 'name' prop. It contains two 'input' components and a 'button'. The 'input' components are expected to use v-model for data binding (though the actual data binding mechanism would need to be implemented by the parent component).

Example 3: Handling Unknown Component

Input Configuration:
{
  "type": "div",
  "children": [
    { "type": "p", "textContent": "This is a known component." },
    { "type": "unknownComponent", "textContent": "This should not render." }
  ]
}

Expected Rendered Output (Conceptual Vue Template):
<div>
  <p>This is a known component.</p>
  <!-- unknownComponent is not rendered or a placeholder/error message is shown -->
</div>

Explanation:
The 'unknownComponent' is not found in the mapping, so it is gracefully ignored or replaced with an error indicator, preventing the application from crashing.

Constraints

• The configuration object will be valid JSON or a JavaScript object literal.
• Component types will be represented as strings.
• Props will be represented as key-value pairs within a props object.
• Text content will be a string in the textContent property.
• You are expected to use Vue 3 Composition API with TypeScript.
• Performance is important; avoid deep recursion that could lead to stack overflow on extremely large configurations.

Notes

• Consider how you will manage the mapping between string component names and actual Vue components. A global registry or passing component maps as props are common approaches.
• For event handlers like onClick, you'll need a mechanism to bind these to methods in your Vue component's logic. This might involve passing a context object with available methods.
• Think about how to handle dynamic data binding (e.g., v-model) for input elements. This might require passing data binding logic or expecting specific prop names.
• The textContent property is a simplified way to handle children. Real-world scenarios might involve more complex children arrays or slot mechanisms.
• Success is measured by the ability to correctly render a variety of UI structures defined purely by configuration.
