Need Help: Generating Triple-Slash Compatible Type Declarations for Legacy App

[ambua]

Problem

I need to generate triple-slash compatible *.d.ts type declaration file for GrapesJS to work with a legacy application. The official index.d.ts file causes issues because the legacy app relies on namespaces rather than ES modules.

Current Setup

• Using GrapesJS with a legacy application
• Need to support triple-slash references and namespaces

What I've Tried

I attempted to use dts-bundle-generator (see my forked branch commit: e65eda4) but encountered multiple errors.

Required Format

The type declarations index.d.ts need to follow this pattern:

/// <reference types="jquery" />

// import Backbone from 'backbone'; // import does not work since want to use triple-slash ref or namespace
declare namespace Backbone {
  // Backbone type definitions
}

declare namespace grapesjs {
  interface Component extends Backbone.Model<ComponentModelProperties> {
    // component definitions
  }
  // other interfaces
}

Any idea or help how to achive this?
