Major Changes
89d242fThanks @TooTallNate! - BREAKING CHANGE: RemoveisWorkflowSdkFilepath-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/coreto be discovered and bundled correctly.Patch Changes
#1669
dc0c0dcThanks @TooTallNate! - Fix step bundle discovery and externalization for SDK serde classesimportParentstracking to all imports (not just file extensions) soparentHasChild()works through bare specifier importsworkflow/runtimein discovery inputs so SDK serde classes likeRunare always discovered#1562
e436242Thanks @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 nativeimport.meta.urlsupport and eliminating the need for CJS polyfills. Fully-bundled ESM output includes acreateRequirebanner to support CJS dependencies that userequire()for Node.js builtins. The intermediate workflow bundle (which runs insidevm.runInContext) remains CJS as required by the VM execution model.#1670

Major Changes
0a86de3Thanks @TooTallNate! - BREAKING CHANGE: Inline all step registrations as self-contained IIFEs instead of generatingimport { registerStepFunction } from "workflow/internal/private". Closure variable access is also inlined. This eliminates the dependency on theworkflowpackage being available innode_modules, enabling 3rd-party packages to define step functions. Registrations are now placed immediately after each function definition instead of being batched at the bottom of the file.Minor Changes
d040182Thanks @TooTallNate! - Allow synchronous functions to use"use step"directive. This enables using"use step"as a mechanism to strip Node.js-dependent code from the workflow VM bundle without requiring the function to be async.Patch Changes
