Release v0.9.0: Fixed Node.js Native ESM Compatibility / Added SuperJSON Transformer Support

[0.9.0] - 2026-04-09

Added

• SuperJSON Transformer Support - The test playground now fully supports tRPC routers using the
  superjson transformer. Configure with generateDocsHtml(routes, { transformer: 'superjson' })
  to automatically:
  • Wrap request inputs in { json: ... } format expected by superjson
  • Unwrap response data from { result: { data: { json: ... } } } structure
  • Enable seamless testing of endpoints that return Date objects, undefined, BigInt, Map,
    Set, and other non-JSON types
  • See the new "SuperJSON Support" section in README for complete usage guide

Fixed

• Node.js Native ESM Compatibility - Package now works correctly with Node.js native ESM
  resolution (Node 16+, Node 22+):
  • All relative imports now include explicit .js file extensions as required by the ECMAScript
    spec
  • Updated TypeScript config to use "moduleResolution": "node16" and "module": "Node16" for
    proper ESM compliance
  • Resolves ERR_MODULE_NOT_FOUND errors when importing the package without a bundler
  • Fully backward compatible with existing bundler-based workflows (Vite, webpack, Rollup, etc.)
