Missing TypeScript declarations for subpath exports (react-native) #387

Description

The contentstack package provides subpath exports like contentstack/react-native, contentstack/web,
and contentstack/nativescript, but does not include corresponding TypeScript declaration files (.d.ts).

Environment

• contentstack version: 3.24.1 (also affects latest 3.27.0)
• TypeScript version: 5.x
• Package managers: npm/yarn

Steps to Reproduce

1. Install contentstack in a TypeScript project:

   npm install contentstack
   

2. Import the React Native entry point:
   import Contentstack from 'contentstack/react-native';
3. TypeScript error:
   Could not find a declaration file for module 'contentstack/react-native'.
   '/path/to/node_modules/contentstack/react-native.js' implicitly has an 'any' type.
   Try npm i --save-dev @types/contentstack if it exists or add a new declaration
   (.d.ts) file containing declare module 'contentstack/react-native';

Current Behavior

• The package provides index.d.ts for the main entry point
• Subpath exports (react-native.js, web.js, nativescript.js) have no corresponding .d.ts files
• TypeScript cannot infer types for these imports

Expected Behavior

TypeScript should pick up types for all provided entry points.

Suggested Solutions

either add react-native.d.ts, web.d.ts, and nativescript.d.ts that re-export the root types or use package.json exports field
