v0.16.0

Added

@coji/durably

• Durable step attempts: Persist each callback attempt and optional JSON metadata across worker crashes, including unresolved attempts, and expose them through getStepAttempts(runId) (#193).

• Parallel step joins: step.all({ branchName: callback }) runs named branches concurrently, replays completed branches after recovery, and keeps branch-specific attempt logs and checkpoint output when a sibling fails (#195).

• Durable external waits: Prepare and resolve persistent input addresses, suspend without occupying a worker slot or concurrency key, and resume the same run by checkpoint replay. Includes optional deadlines, input-wait and execution-slot timing, cancellation, idempotent signal receipts, direct wait queries, and waiting-aware active coalescing (#203, #204).

• HTTP durable waits: Inspect waits and deliver signals through run-authorized HTTP endpoints, with atomic accepted/duplicate receipts, explicit expired-wait responses, and reconnect-safe persisted reads. Includes outbound CI polling and local human-input examples (#205).

• coalesce: 'queue' option: Added 'queue' to the coalesce trigger option (trigger(), triggerAndWait(), batchTrigger(), and HTTP /trigger). In this release, 'queue' is behaviorally equivalent to 'skip': both create one trailing pending run behind an active leased run, and reuse an existing pending run with disposition 'coalesced'. Further triggers while a trailing run is pending are coalesced without replacing its input (#198).

• coalesce: 'active' option: Reuse the oldest pending run or a same-job leased run with a valid lease for a concurrency key, otherwise create a pending run. Active selection is atomic across SQLite, libSQL, and PostgreSQL runtimes; coalesced events and HTTP responses expose the selected run status (#199).

@coji/durably-react

• Waiting run tracking: Hooks and HTTP run projections expose isWaiting, restore waiting runs on mount/reconnect, and preserve the pending/leased definition of isActive (#203).

• Scoped useJob tracking: SPA and fullstack hooks accept scope.labels and triggerOptions, expose isResolving, hydrate pending or leased selections immediately, and reject stale lookup results after triggers or scope changes. SPA followLatest now follows matching run:trigger events while runs are pending, as well as coalesced and leased events (#199).

Changed

@coji/durably

• Breaking: Node.js 22+ required for the published core package. The bundled better-sqlite3 driver moves to v13 (#189).
• Kysely compatibility: The peer dependency now supports 0.27, 0.28, and 0.29 (#189).

@coji/durably-react

• The optional @coji/durably peer now requires ^0.16.0 when using the core package; docs/llms.md is included in the npm package (#208).

Fixed

@coji/durably

• SSE responses now set Cache-Control: no-cache, no-transform so compression middleware forwards events without leaving fullstack clients showing a completed run as pending (#189).
