1.4.0

coaction v1.4.0

This release includes core async-store improvements, compatibility fixes for the 1.x line, expanded browser E2E coverage, and a tooling refresh across the workspace.

Highlights

• Added executeSyncTimeoutMs to coaction so async clients can control how long they wait for sequence catch-up before falling back to fullSync.
• Preserved 1.x middleware and worker compatibility by keeping deprecated patch, trace, and workerType hooks/options available while introducing
  MiddlewareStore as the preferred middleware-facing type.
• Kept sliceMode: 'auto' backward-compatible for object-of-functions inputs, while adding a development warning for that ambiguous shape and recommending explicit sliceMode usage.
• Refactored getRawState internals into smaller modules without intended behavior changes.

Testing and CI

• Expanded browser E2E coverage for middleware scenarios.
• Added real browser E2E coverage for Web Worker and Shared Worker flows.
• Wired browser E2E into the pull request workflow.
• Migrated the repo lint workflow to ESLint and removed the legacy TSLint config.

Package Notes

• @coaction/logger
  • Updated middleware typings to align with MiddlewareStore without changing runtime behavior.
• @coaction/react
  • Clarified the continued use of use-sync-external-store/shim to keep a single build compatible with React 17, 18, and 19.
• Other adapters and middleware packages
  • Aligned peer dependency ranges with coaction@^1.4.0.

Upgrade Notes

• No breaking runtime changes are intended in the 1.x line.
• If you create stores from an object whose enumerable values are all functions, set sliceMode explicitly to avoid the new development warning.
• If you use async client stores under heavy load, consider configuring executeSyncTimeoutMs for your transport latency profile.
