    Workflow Development Kit by Vercel

    [email protected]

    Workflow Development Kit releases fixes for replay ordering and exact Unicode string round-tripping, removes an experimental dispatch option, and improves Vercel HTTP stream retries after confirmed rate limits.

    @workflow/[email protected]

    • #4861 afdc68b @pranaygp - Order setAttributes() resolution with the replay delivery barriers so a branch awaiting it can no longer resume out of event-log order, which could fail the run with REPLAY_DIVERGENCE or hand concurrent branches each other's step results
    • #4856 a04ecaa @http-samc - Upgrade devalue to 6.0.3, which escapes large strings with native JSON.stringify instead of a per-character loop. Strings containing unpaired surrogates now round-trip exactly instead of being replaced with U+FFFD.
    • #4818 0948b0a @VaguelySerious - Remove the experimental WORKFLOW_RESILIENT_STEP_DISPATCH option

    @workflow/[email protected]

    • #4828 02993a2 @mmarufov - Fix UND_ERR_REQ_CONTENT_LENGTH_MISMATCH by retrying HTTP stream appends with fresh bodies after confirmed 429s, using the shared throttle wait policy. Retry only connection-refused, DNS, and connect-timeout failures; surface other transport errors without replay.

    Workflow Development Kit by Vercel

    [email protected]

    Workflow Development Kit releases updates that improve workflow startup performance, queue routing and recovery, event-write consistency, and inspection tools. The release also fixes stream listing, pagination, and runtime stability issues across local, PostgreSQL, and Vercel backends.

    @workflow/[email protected]

    • #4669 854242e @http-samc - Compress workflow arguments on the libuv threadpool when starting a run, so large inputs no longer block the caller's event loop during zstd compression.
    • #4670 73a6ca3 @http-samc - Add a compressArguments option to start(); pass false to store the run's arguments uncompressed when the inputs are known to be incompressible.
    • #4835 fcb554b @pranaygp - Record the queue namespace on a run's executionContext.queueNamespace in start(), so restart recovery re-enqueues the run to its own namespace.

    @workflow/[email protected]

    • #4760 1342a96 @pranaygp - Improve workflow inspect for long runs and scoped lookups: add --all for complete steps, events, and sleeps listings, print reusable cursor hints, and keep pagination on the read path that issued the cursor. Support event ID and short workflow-name lookups, require --runId for individual steps, events, and streams, fix st to mean streams, include run IDs in stream hints, and exit non-zero when a stream read fails.

    @workflow/[email protected]

    • #4733 e6bd692 @VaguelySerious - Add InBandSupersededError and optional inBand/expectedSeqInBand event-create params for the in-band writer fence. @workflow/world-vercel forwards them, does not retry a fenced write in-process, and records the fence on its event spans. The runtime does not use them yet.
    • #4835 fcb554b @pranaygp - Add optional Queue.registerRoute() and Queue.registerHandler(), implemented by @workflow/world-local and @workflow/world-postgres, so a queue consumer other than the Workflow SDK receives its own prefix's messages on its own route or in process. reenqueueActiveRuns() re-enqueues a run to the queue namespace it recorded, and @workflow/world-postgres keeps a job's queue prefix.
    • #4821 ebaa5b7 @VaguelySerious - Implement the optional in-band writer fence and list snapshot in @workflow/world-local and @workflow/world-postgres, declared with the new inBandFence capability.
    • #4821 ebaa5b7 @VaguelySerious - Report deliveryCount and createdAt in queue handler meta on @workflow/world-local and @workflow/world-postgres.
    • #4833 3e93033 @pranaygp - @workflow/world-vercel declares the inBandFence capability (its backend refuses a stale in-band write on every run with an event sequencer, and answers an in-band write on an older run with a 400), and passes on the in-band counts its backend reports: snapshot on events.list and allocated on a single events.create. The inBandFence contract lets a World list no snapshot when its refusals carry both counters, and @workflow/world-testing takes the counters from a refusal for such a World.

    @workflow/[email protected]

    • #4835 fcb554b @pranaygp - Add optional Queue.registerRoute() and Queue.registerHandler(), implemented by @workflow/world-local and @workflow/world-postgres, so a queue consumer other than the Workflow SDK receives its own prefix's messages on its own route or in process. reenqueueActiveRuns() re-enqueues a run to the queue namespace it recorded, and @workflow/world-postgres keeps a job's queue prefix.
    • #4821 ebaa5b7 @VaguelySerious - Implement the optional in-band writer fence and list snapshot in @workflow/world-local and @workflow/world-postgres, declared with the new inBandFence capability.
    • #4838 b69fabe @fazxes - Fix initDataDir() crashing on Bun for a new data directory: Bun's opendir() reports a missing directory on the first read, not when it is opened.
    • #4834 77ccb69 @pranaygp - Fix in-band event count conflicts when multiple processes write events, and fix count not surviving world restarts
    • #4754 c57820d @pranaygp - Register a run's stream names under a lock so streams.list no longer drops a stream when several of the run's streams first write at once. A stream written again after clear() is listed again.
    • #4821 ebaa5b7 @VaguelySerious - Report a message's cumulative deliveryCount across { timeoutSeconds } redeliveries on @workflow/world-postgres.
    • #4821 ebaa5b7 @VaguelySerious - Report deliveryCount and createdAt in queue handler meta on @workflow/world-local and @workflow/world-postgres.

    @workflow/[email protected]

    • #4817 026741b @VaguelySerious - Fix a process crash when the database closes an idle connection
    • #4835 fcb554b @pranaygp - Add optional Queue.registerRoute() and Queue.registerHandler(), implemented by @workflow/world-local and @workflow/world-postgres, so a queue consumer other than the Workflow SDK receives its own prefix's messages on its own route or in process. reenqueueActiveRuns() re-enqueues a run to the queue namespace it recorded, and @workflow/world-postgres keeps a job's queue prefix.

    • #4821 ebaa5b7 @VaguelySerious - Report a message's cumulative deliveryCount across { timeoutSeconds } redeliveries on @workflow/world-postgres.
    • #4756 e631e78 @pranaygp - Honor pagination.sortOrder in runs.list and steps.list, which always returned newest first.
    • #4821 ebaa5b7 @VaguelySerious - Report deliveryCount and createdAt in queue handler meta on @workflow/world-local and @workflow/world-postgres.

Support event ID and short workflow-name lookups, require --runId for individual steps, events, and streams, fix st to mean streams, include run IDs in stream hints, and exit non-zero when a stream read fails.

    Workflow Development Kit by Vercel

    @workflow/[email protected]: Version Packages (#4776)

    Workflow Development Kit releases improvements to workflow performance, queue handling, and run inspection, alongside stronger event-write safeguards and fixes for local and database-backed worlds.

    This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

    1342a96

    Thanks @pranaygp! - Improve workflow inspect for long runs and scoped lookups: add --all for complete steps, events, and sleeps listings, print reusable cursor hints, and keep pagination on the read path that issued the cursor. Support event ID and short workflow-name lookups, require --runId for individual steps, events, and streams, fix st to mean streams, include run IDs in stream hints, and exit non-zero when a stream read fails.

    #4669

    854242e

    Thanks @http-samc! - Compress workflow arguments on the libuv threadpool when starting a run, so large inputs no longer block the caller's event loop during zstd compression.

    #4670

    73a6ca3

    Thanks @http-samc! - Add a compressArguments option to start(); pass false to store the run's arguments uncompressed when the inputs are known to be incompressible.

    #4835

    fcb554b

    Thanks @pranaygp! - Record the queue namespace on a run's executionContext.queueNamespace in start(), so restart recovery re-enqueues the run to its own namespace.

    Thanks @VaguelySerious! - Add InBandSupersededError and optional inBand/expectedSeqInBand event-create params for the in-band writer fence. @workflow/world-vercel forwards them, does not retry a fenced write in-process, and records the fence on its event spans. The runtime does not use them yet.

    Thanks @pranaygp! - @workflow/world-vercel declares the inBandFence capability (its backend refuses a stale in-band write on every run with an event sequencer, and answers an in-band write on an older run with a 400), and passes on the in-band counts its backend reports: snapshot on events.list and allocated on a single events.create.

    3e93033

    Thanks @pranaygp! - @workflow/world-vercel declares the inBandFence capability (its backend refuses a stale in-band write on every run with an event sequencer, and answers an in-band write on an older run with a 400), and passes on the in-band counts its backend reports: snapshot on events.list and allocated on a single events.create. The inBandFence contract lets a World list no snapshot when its refusals carry both counters, and @workflow/world-testing takes the counters from a refusal for such a World.

    Workflow Development Kit by Vercel

    @workflow/[email protected]: Version Packages (#4776)

    Workflow Development Kit releases updates that improve long-running workflow inspection, keep large-run startup responsive, and strengthen queue routing, event consistency, and stream handling across supported backends.

    This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to main, this PR will be updated.

    1342a96

    Thanks @pranaygp! - Improve workflow inspect for long runs and scoped lookups: add --all for complete steps, events, and sleeps listings, print reusable cursor hints, and keep pagination on the read path that issued the cursor. Support event ID and short workflow-name lookups, require --runId for individual steps, events, and streams, fix st to mean streams, include run IDs in stream hints, and exit non-zero when a stream read fails.

    #4669

    854242e

    Thanks @http-samc! - Compress workflow arguments on the libuv threadpool when starting a run, so large inputs no longer block the caller's event loop during zstd compression.

    #4670

    73a6ca3

    Thanks @http-samc! - Add a compressArguments option to start(); pass false to store the run's arguments uncompressed when the inputs are known to be incompressible.

    #4835

    fcb554b

    Thanks @pranaygp! - Record the queue namespace on a run's executionContext.queueNamespace in start(), so restart recovery re-enqueues the run to its own namespace.

    #4733

    e6bd692

    Thanks @VaguelySerious! - Add InBandSupersededError and optional inBand/expectedSeqInBand event-create params for the in-band writer fence. @workflow/world-vercel forwards them, does not retry a fenced write in-process, and records the fence on its event spans. The runtime does not use them yet.

    Thanks @pranaygp! - Add optional Queue.registerRoute() and Queue.registerHandler(), implemented by @workflow/world-local and @workflow/world-postgres, so a queue consumer other than the Workflow SDK receives its own prefix's messages on its own route or in process. reenqueueActiveRuns() re-enqueues a run to the queue namespace it recorded, and @workflow/world-postgres keeps a job's queue prefix.

    b69fabe

    Thanks @fazxes! - Fix initDataDir() crashing on Bun for a new data directory: Bun's opendir() reports a missing directory on the first read, not when it is opened.

    #4834

    77ccb69

    Thanks @pranaygp! - Fix in-band event count conflicts when multiple processes write events, and fix count not surviving world restarts

    #4754

    c57820d

    Thanks @pranaygp! - Register a run's stream names under a lock so streams.list no longer drops a stream when several of the run's streams first write at once. A stream written again after clear() is listed again.

    #4821

    ebaa5b7
