Vue Dependency Analysis Tool

Understanding component dependencies is crucial for efficient refactoring, debugging, and performance optimization in Vue.js applications. This challenge asks you to implement a tool that analyzes a Vue component's template and script to identify its dependencies on other components, directives, and filters. This tool will help developers visualize and manage the relationships between different parts of their Vue application.

Problem Description

You are tasked with creating a TypeScript function analyzeComponentDependencies that takes a Vue component definition (as a plain JavaScript object) as input and returns an object representing the component's dependencies. The component definition will include template, script (containing setup function and potentially other methods), components, directives, and filters properties.

The function should:

1. Identify Component Dependencies: Parse the template string and extract any component names used within the template (e.g., <MyComponent />). These names should be added to the components array in the output.
2. Identify Directive Dependencies: Parse the template string and extract any directive names used within the template (e.g., v-model). These names should be added to the directives array in the output.
3. Identify Filter Dependencies: Parse the template string and extract any filter names used within the template (e.g., {{ myValue | myFilter }}). These names should be added to the filters array in the output.
4. Handle components Property: The component definition may already include a components object. Your function should merge the dependencies found in the template with the existing components object, ensuring no duplicates.
5. Handle directives and filters Properties: Similar to components, merge the dependencies found in the template with any existing directives and filters properties.
6. Handle setup function: If the script property contains a setup function, analyze the function body for references to other components, directives, or filters. Add these to the dependency lists as appropriate. (This is a simplified analysis; full scope resolution is not required).

Expected Behavior:

The function should return an object with the following structure:

{
  components: string[];
  directives: string[];
  filters: string[];
}

Examples

Example 1:

Input:
{
  template: '<MyComponent v-model="value" | myFilter="value" />',
  script: {
    setup() {
      return {
        value: 123,
      };
    }
  },
  components: {
    AnotherComponent: AnotherComponentImpl
  },
  directives: {},
  filters: {}
}

Output:
{
  components: ["MyComponent", "AnotherComponent"],
  directives: ["v-model"],
  filters: ["myFilter"]
}

Explanation: The template uses `MyComponent`, `v-model`, and `myFilter`. The `components` property already defines `AnotherComponent`.  The output merges these.

Example 2:

Input:
{
  template: '<div><ChildComponent /></div>',
  script: {},
  components: {},
  directives: {},
  filters: {}
}

Output:
{
  components: ["ChildComponent"],
  directives: [],
  filters: []
}

Explanation: The template uses `ChildComponent`.  Since there are no existing components, directives, or filters, the output contains only the dependency found in the template.

Example 3: (Edge Case - No Dependencies)

Input:
{
  template: '<div></div>',
  script: {},
  components: {},
  directives: {},
  filters: {}
}

Output:
{
  components: [],
  directives: [],
  filters: []
}

Explanation: The template contains no dependencies. The output is empty arrays for all dependency types.

Constraints

• The template string will be a valid Vue template string.
• The script property will be a plain JavaScript object.
• Component names, directive names, and filter names will be simple strings (no complex expressions).
• The analysis of the setup function is limited to identifying direct references to component names, directive names, and filter names within the function body. Full scope resolution is not required.
• Performance: The function should be reasonably efficient for typical Vue component sizes (template length < 1000 characters, script size < 500 lines).

Notes

• You can use regular expressions to parse the template string.
• Consider using a simple string search approach for identifying dependencies within the setup function.
• Focus on identifying the names of the dependencies, not their implementations.
• The order of dependencies in the output arrays does not matter.
• Assume that the input component definition is well-formed. Error handling for invalid input is not required.
• This is a simplified dependency analysis tool. A real-world tool would require more sophisticated parsing and scope resolution.
