Added support for es6

[ankitdas13]

feat: add ESM support with dual CJS/ESM build (v3.0.0)

What

Adds native ES6 / ESM support to the Razorpay Node SDK while maintaining full backward compatibility with existing CommonJS users.

Why

The SDK previously only shipped a CommonJS build (dist/razorpay.js). Consumers using import Razorpay from 'razorpay' in ESM projects, modern bundlers (Vite, Rollup), or TypeScript with "module": "ESNext" had no native ESM entry point.

Changes

Build system

• Replaced Babel (babel-cli, babel-preset-env, babel-preset-stage-0) with tsup for a faster, modern dual-format.

build

• Added tsup.config.ts — produces three build targets:
  • dist/razorpay.mjs — ESM build
  • dist/razorpay.js — CJS build (with module.exports unwrap for zero breaking changes)
  • dist/oAuthTokenClient.js, dist/utils/* — CJS utility modules

package.json

• Added "module": "dist/razorpay.mjs" for bundler resolution
• Added "exports" field with conditional import / require / types paths
• Added subpath exports for all deep imports (dist/oAuthTokenClient, dist/utils/razorpay-utils, dist/types/*) to preserve backward compatibility
• Upgraded typescript from ^4.9.4 → ^5.9.3
• Removed unused Babel devDependencies; added tsup: ^8.5.1
• Fixed cp-types script (mkdir -p, corrected *.d.ts glob)
