Workflow Development Kit Updates & Release Notes

@workflow/[email protected]

#2059 49da6c5 @TooTallNate - A WritableStream from a workflow's getWritable() can now be passed as an argument to a child workflow via start(); the child's writes land on the parent run's stream directly for the full lifetime of the child run.
#2038 dc0be50 @pranaygp - Refresh workflow events after completing elapsed waits so concurrent hook events preserve deterministic replay order.
#2046 ad71b58 @pranaygp - Report corrupted event logs with a distinct CorruptedEventLogError type and CORRUPTED_EVENT_LOG run error code.
#2056 9454151 @VaguelySerious - Fix spurious "Event cursor missing after initial load" warning
#2030 b124365 @pranaygp - Validate step, wait, and hook lifecycle events against replay ownership metadata.
#2013 2a446af @TooTallNate - Exclude inline step execution from the workflow replay timeout. Long-running steps no longer hit REPLAY_TIMEOUT (fixes #2009). Adds a WORKFLOW_REPLAY_TIMEOUT_MS env var override and a new optional World.processExitTriggersQueueRedelivery capability used to gate the runtime's process.exit(1) failure path.
#2060 1d3959e @pranaygp - Record fatal world response contract failures as non-retryable workflow errors.

#2060 1d3959e @pranaygp - Record fatal world response contract failures as non-retryable workflow errors.

@workflow/[email protected]

#2043 96e2d3c @TooTallNate - Fix race condition in test server's flow invocation counter that caused intermittent failures in the inline-execution test suite (e.g. "sequential steps complete in a single flow invocation"). The counter is now incremented before awaiting the flow handler, so the count is observable as soon as the run transitions to completed.

@workflow/[email protected]

#2036 753e39e @mitul-s - trace viewer bug fix + file cleanup
#2022 5a393a6 @mitul-s - updated colours on the trace viewer
#2045 366f9cc @mitul-s - Add reduced motion for the trace viewer

@workflow/[email protected]

#1575 c1242e8 @RihanArfan - Match the webhook functionRules key (:token) to the handler route on Nitro v3 Vercel deploys so the runtime override is applied to the real webhook/[token].func instead of generating a duplicate webhook/[...].func. Also propagate workflow.runtime to the public manifest route for consistency.

@workflow/[email protected]

#2046 ad71b58 @pranaygp - Report corrupted event logs with a distinct CorruptedEventLogError type and CORRUPTED_EVENT_LOG run error code.

@workflow/[email protected]

• #1955 73e0c4d @mitul-s - Show hook name on trace viewer + no toast on decrypt
• #2087 88070cf @VaguelySerious - Fix the "Queued for" duration shown in the events list for retried steps. It now measures from step_created to the first step_started instead of the last, so the displayed value reflects actual queue time rather than queue time plus all retry waits.
• #1952 01cfe19 @mitul-s - Fix old trace viewer layout to be in a row rather than column

@workflow/[email protected]

• #1944 a9cc1d5 @TooTallNate - Fix three bugs affecting nested step functions that get hoisted out of an enclosing function (workflows in any declaration form, plus regular factory-style functions returning objects with step methods): 1. Module-level imports referenced only by hoisted step bodies were stripped by dead-code elimination, causing a ReferenceError at runtime. 2. The step ID generated for nested anonymous steps inside a non-exported workflow declared as const foo = async () => {} or const foo = async function() {} was not namespaced under the workflow name in step mode, so it did not match the ID looked up by the workflow-mode proxy and caused a runtime "step not found" failure. Steps inside async function foo() workflows were already namespaced correctly; this brings the const-arrow and const-fn-expression forms into agreement. 3. The __internal_workflows manifest comment reported nested anonymous step IDs without the workflow-name prefix even though the runtime registration and proxy lookup used the prefixed form, so downstream tooling (e.g. builders consuming the manifest) saw the wrong step ID.
• #1935 6aabd6f @TooTallNate - Fix arguments being incorrectly captured as a closure variable in nested function-form step bodies, which previously produced invalid output.
• #1935 6aabd6f @TooTallNate - Support this references inside nested arrow "use step" functions. Requires the enclosing class to have custom serialization.

• #1851 5f22832 @TooTallNate - BREAKING CHANGE: Run and step errors are now serialized through the workflow serialization pipeline, preserving original class identity and cause chains on WorkflowRunFailedError.cause. Pre-upgrade failed runs in the world-postgres legacy error text column surface as error: undefined on read; the original payload is still readable directly from the errorJson column for manual inspection.
• #1511 e7ea068 @TooTallNate - Add first-class serialization support for built-in Error subclasses (TypeError, RangeError, SyntaxError, URIError, ReferenceError, EvalError, AggregateError) and preserve the cause property on all Error types
• #1513 74b13cd @TooTallNate - Add first-class serialization for FatalError and RetryableError so they round-trip with class identity preserved across all serialization boundaries (including from environments that don't run the SWC plugin)
• #1301 aee5699 @pranaygp - Drain pending queue items at workflow completion instead of only logging warnings, and implicitly dispose any never-aborted system (abort) hooks at completion so unused AbortController instances don't leave abandoned rows in the hooks table for the run's TTL
• #1301 aee5699 @pranaygp - Fix DOMException not serializing correctly
• #1924 3535caf @VaguelySerious - Fix Promise.race(step, sleep) always blocking until step completed

New SerializationError, WorkflowBuildError, and structured context-violation classes (e.g. NotInWorkflowContextError) with actionable hints and docs links applied to user-facing throw sites; FatalError.is() recognizes any error with fatal: true so context violations and serialization failures now fail fast instead of burning retry attempts. Runtime logs are namespaced under [workflow-sdk] and gain errorAttribution (user vs sdk) plus class-aware hints
• #1747 00a011d @ijjk - Fix eager Next.js workflow builds with lazy discovery disabled.
• #1849 1203dae @pranaygp - Replace util.inspect's default object dump for runtime structured-log metadata with an opinionated, workflow-aware formatter. The runtime logger uses color-coded metadata blocks.
• #1301 aee5699 @pranaygp - Add serializable AbortController and AbortSignal support across workflow and step boundaries. Workflow code can now construct an AbortController, pass signal to steps, and call abort().

• #1851 5f22832 @TooTallNate - BREAKING CHANGE: Run and step errors are now serialized through the workflow serialization pipeline, preserving original class identity and cause chains on WorkflowRunFailedError.cause. Pre-upgrade failed runs in the world-postgres legacy error text column surface as error: undefined on read; the original payload is still readable directly from the errorJson column for manual inspection.
• #1915 540a2ef @VaguelySerious - Replace the chalk import in @workflow/errors/ansi with a tiny inline ANSI shim. @workflow/errors/ansi is reachable from the workflow-VM bundle (via @workflow/core/workflow → context-errors → context-violation-error → here), and chalk pulls in supports-color, which calls require('os') at module load — crashing every workflow with ReferenceError: require is not defined in the sandboxed VM.
• #1849 1203dae @pranaygp - Friendlier workflow error messages. New SerializationError, WorkflowBuildError, and structured context-violation classes (e.g. NotInWorkflowContextError) with actionable hints and docs links applied to user-facing throw sites; FatalError.is() recognizes any error with fatal: true so context violations and serialization failures now fail fast instead of burning retry attempts. Runtime logs are namespaced under [workflow-sdk] and gain errorAttribution (user vs sdk) plus class-aware hints
• #1849 1203dae @pranaygp - Replace util.inspect's default object dump for runtime structured-log metadata with an opinionated, workflow-aware formatter. The runtime logger uses color-coded metadata blocks.

#1848 7d07fab @pranaygp - Replace eval in serialization.ts revive() helper with JSON.parse. devalue.stringify() output is always valid JSON (special values are encoded as negative integer sentinels), so JSON.parse is a safe drop-in that eliminates the eval anti-pattern.

#1686 417c493 @TooTallNate - BREAKING CHANGE: Remove client transform mode from SWC plugin. The client and step modes were nearly identical — both preserved step function bodies, replaced workflow bodies with throw stubs, and emitted the same JSON manifest. The only differences were the step registration mechanism (simple property assignment vs. IIFE) and whether DCE ran. Step mode now absorbs all client-mode behaviors: hoisted variable references for object property steps (so .stepId is accessible), and dead code elimination. All integrations that previously used mode: 'client' now use mode: 'step'.

#1632 0a86de3 @TooTallNate - BREAKING CHANGE: Inline all step registrations as self-contained IIFEs instead of generating import { registerStepFunction } from "workflow/internal/private".

This allows class definitions with serde symbols in SDK packages like @workflow/core to be discovered and bundled correctly.

#1669 dc0c0dc @TooTallNate - Fix step bundle discovery and externalization for SDK serde classes - Broaden importParents tracking to all imports (not just file extensions) so parentHasChild() works through bare specifier imports - Include workflow/runtime in discovery inputs so SDK serde classes like Run are always discovered - Bundle node_modules deps instead of externalizing with broken relative paths

#1562 e436242 @VaguelySerious - Switch Vercel Build Output API and standalone builder output from CJS to ESM. Step bundles, workflow bundles, and webhook bundles now emit ESM format by default, preserving native import.meta.url support and eliminating the need for CJS polyfills. Fully-bundled ESM output includes a createRequire banner to support CJS dependencies that use require() for Node.js builtins. The intermediate workflow bundle (which runs inside vm.runInContext) remains CJS as required by the VM execution model.

#1670 32a17b4 @TooTallNate - Fix lazy discovery bare specifier resolution in copied step files - Use enhanced-resolve with ESM conditions to resolve bare specifiers from the original source file's location - Only rewrite specifiers that can't resolve from the app directory (transitive SDK deps) - Add enhanced-resolve to pnpm catalog and use catalog: in both packages

#1662 89d242f @TooTallNate - BREAKING CHANGE: Remove isWorkflowSdkFile path-based serde exclusion. Serde discovery now uses AST-level verification via SWC detect mode across all integration paths (esbuild plugin, Next.js deferred builder, Next.js loader). This allows class definitions with serde symbols in SDK packages like @workflow/core to be discovered and bundled correctly.
