[builders] Fix transitive local TS dep externalization in step bundles by VaguelySerious · Pull Request #1609 · vercel/workflow

VaguelySerious · 2026-04-03T21:49:54Z

Summary

Fixes transitive local TypeScript dependencies being externalized instead of bundled in step/workflow bundles, which caused native ESM crashes in Nuxt dev (and other frameworks) when extensionless relative imports like ./helpers couldn't be resolved by Node.

Root cause (two issues):

The discover-entries plugin's onResolve filter only matched imports with explicit file extensions (jsTsRegex). Extensionless imports like ./helpers were never tracked in importParents, leaving the dependency graph incomplete.
The swc plugin only checked if a resolved file was an ancestor of an entry (parentHasChild(resolved, entry)), but never checked if it was a descendant (parentHasChild(entry, resolved)). So even with a correct import graph, transitive local deps got externalized.

Fix:

Configure enhanced-resolve in the discover plugin with TS extensions so extensionless imports resolve correctly
Broaden the onResolve filter from jsTsRegex to /^[./]/ (relative imports only) to track extensionless local deps
Add a reverse parentHasChild(entry, resolved) check in the swc plugin so descendants of entries are bundled

Test plan

Added test for extensionless import tracking in discover-entries-esbuild-plugin.test.ts
Added test for transitive local dep bundling in swc-esbuild-plugin.test.ts
All 20 builder tests pass
CI passes

…ndles Two issues caused local transitive dependencies to be externalized instead of bundled in step/workflow bundles: 1. The discover-entries plugin's onResolve filter only matched imports with explicit file extensions (jsTsRegex). Extensionless imports like `./helpers` were never tracked in the import graph. 2. The swc plugin only checked if a file was an ancestor of an entry (parentHasChild(resolved, entry)) but never checked if it was a descendant (parentHasChild(entry, resolved)). So even with a correct import graph, transitive local deps got externalized. Fixes: configure enhanced-resolve with TS extensions, broaden the onResolve filter to catch all relative imports, and add the reverse parentHasChild check.

Resolve conflict in discover-entries-esbuild-plugin.ts: keep both relativeImportRegex (from this PR) and hasManifestEntries (from #1641). Update test state types from string[] to Set<string> to match #1641's type change. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Aligns with swc-esbuild-plugin's NODE_ESM_RESOLVE_OPTIONS to ensure both plugins resolve the same paths for parentHasChild() graph lookups, particularly in monorepo setups with symlinked packages. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
