@interface not working as expected?

[ritz078]

Hi everyone! I'm having trouble getting TypeDoc's @interface tag to work properly. I'm trying to convert a type alias into an interface, but it's not expanding the properties as expected.

What I'm trying to do:

const Options = {
  optionA: 'test',
  optionB: 1,
};

/**
 * @interface
 * @property optionA - A test option
 * @property optionB - A numeric option
 */
export type IOptions = typeof Options;

Expected behavior:

TypeDoc should convert the typeof Options type into an interface with explicit optionA and optionB properties, making the documentation more readable.

What's happening:

The @interface tag is being ignored, and TypeDoc still shows the type as typeof Options instead of expanding it into interface properties.

My TypeDoc config:

{
  "$schema": "https://typedoc.org/schema.json",
  "entryPoints": ["src/index.ts"],
  "out": "docs-typedoc",
  "excludePrivate": true,
  "excludeProtected": true,
  "excludeExternals": true,
  "theme": "default",
  "name": "API Extractor Example - TypeDoc",
  "includeVersion": true,
  "categorizeByGroup": true,
  "categoryOrder": ["Classes", "Interfaces", "Functions", "Types", "*"],
  "defaultCategory": "Other",
  "includeHierarchySummary": false,
  "disableSources": true,
  "customCss": "./custom-typedoc.css",
  "excludeInternal": true
}

You are running on some old version of TypeDoc which doesn't support @interface. In 0.28.10 this renders as:
