Summary

  • derive workflow basePath from nextConfig.basePath; users do not configure a separate Workflow env var
  • embed the basePath into generated Next workflow route options for serverless/runtime execution
  • apply the configured basePath to workflow metadata URLs and local/postgres queue delivery URLs while preserving full WORKFLOW_LOCAL_BASE_URL overrides
  • trim the implementation back to one small workflow-config utility instead of separate basePath/route/base-url helpers

Fixes #1864.

This is separate from #2729; it addresses workflow runtime URL construction rather than project root discovery.

Tests

  • pnpm biome check --write ... on touched files
  • pnpm --filter @workflow/utils --filter @workflow/builders --filter @workflow/core --filter @workflow/next --filter @workflow/world-local --filter @workflow/world-postgres build
  • pnpm vitest run src/workflow-config.test.ts from packages/utils
  • pnpm vitest run src/constants.test.ts from packages/builders
  • pnpm vitest run src/index.test.ts from packages/next
  • pnpm vitest run src/config.test.ts src/queue.test.ts from packages/world-local
  • pnpm vitest run src/queue.test.ts from packages/world-postgres
  • local nextjs-turbopack dev E2E: packages/core/e2e/dev.test.ts
  • local nextjs-turbopack dev E2E: pnpm run test:e2e (152 passed)

  • Wall Time: Total testbench time (trigger workflow + poll for result)
  • Overhead: Testbench overhead (Wall Time - Workflow Time)
  • Samples: Number of benchmark iterations run
  • vs Fastest: How much slower compared to the fastest configuration for this benchmark
