📄 Description

Summary

Fixes #292, #543

This updates deepagents packaging to split environment-specific exports and avoid browser build failures caused by Node-only imports in the default bundle. Browser consumers now have an explicit deepagents/browser entrypoint, while Node consumers can keep using deepagents (or optionally deepagents/node) for the full runtime API.

Changes

deepagents package exports and entrypoints

  • Added src/browser.ts as a browser-safe public barrel that excludes Node-only APIs.
  • Added src/node.ts as an explicit Node entrypoint that re-exports the full API.
  • Updated package.json exports to:
    • route the root browser condition to ./dist/browser.js
    • expose ./browser and ./node subpath exports (ESM + CJS + types).
  • Updated tsdown config to build index, browser, and node outputs.

Runtime import graph hardening

  • Updated createDeepAgent to import StateBackend directly from backends/state so it no longer pulls in the full Node-oriented backends barrel.
  • Updated types.ts to import AnyBackendProtocol from backends/protocol instead of backends/index.
  • Removed named Node builtin path imports from backends/utils.ts by replacing path.basename/path.extname with local helpers.

Documentation and release notes

  • Added a README section documenting import guidance: browser apps should use deepagents/browser, and Node apps can continue to use deepagents.
  • Added a patch changeset for deepagents describing the entrypoint and packaging fix.
