Workarounds

  1. 90% success Install the @types/ package for the library 
    npm install --save-dev @types/package-name

  2. 85% success Create a minimal declaration file for the module 
    // Create src/types/package-name.d.ts:
declare module 'package-name' {
  const content: any;
  export default content;
  // Add specific exports as needed
}
