Reduce workflow build log noise

[ijjk]

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

pnpm --filter @workflow/builders test
pnpm --filter @workflow/builders typecheck
pnpm exec biome check packages/builders/src/base-builder.ts packages/builders/src/base-builder-logging.test.ts

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

pnpm --filter @workflow/builders test
pnpm --filter @workflow/builders typecheck
pnpm exec biome check packages/builders/src/base-builder.ts packages/builders/src/base-builder-logging.test.ts

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

pnpm --filter @workflow/builders test
pnpm --filter @workflow/builders typecheck
pnpm exec biome check packages/builders/src/base-builder.ts packages/builders/src/base-builder-logging.test.ts

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

pnpm --filter @workflow/builders test
pnpm --filter @workflow/builders typecheck
pnpm exec biome check packages/builders/src/base-builder.ts packages/builders/src/base-builder-logging.test.ts

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

pnpm --filter @workflow/builders test
pnpm --filter @workflow/builders typecheck
pnpm exec biome check packages/builders/src/base-builder.ts packages/builders/src/base-builder-logging.test.ts

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

Summary

Reduce default workflow build output to one completion line while keeping detailed build progress available behind DEBUG=workflow:build.

Subsequent builds from the same dev-server builder instance are labeled as rebuilds, which covers HMR/watch rebuilds in Next, Nitro, Astro, and SvelteKit.

Log output

Before:

Discovering workflow directives 2444ms
Created step registrations 358ms
Created intermediate workflow bundle 788ms
Creating webhook route
Creating manifest...
Created manifest with 43 steps, 9 workflows, and 4 classes 359ms

After initial build:

workflows build complete (43 steps, 9 workflows, time 3.5s)

After an HMR/watch rebuild:

workflows rebuilt (43 steps, 9 workflows, time 800ms)

Verbose progress logs remain available with:

DEBUG=workflow:build pnpm build

Validation

• 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
