Matias Torsello d427c47e89 fix(core): allow Next.js route groups and dynamic segments in workflow names (#4070)
A workflow name is derived from the module path it is defined in, so Next.js
App Router conventions end up in the name verbatim. `SAFE_WORKFLOW_NAME_PATTERN`
permitted alphanumerics, `_`, `-`, `.`, `/` and `@`, but not parentheses or
square brackets. Any workflow inside a route group (`app/(dashboard)/...`) or a
dynamic segment (`app/[teamId]/...`, `app/[...slug]/...`) threw

    Invalid workflow name "workflow//./app/(group)/workflows/": must only
    contain alphanumeric characters, ...

before it could be enqueued, and the generated name cannot be overridden.

The pattern exists to keep unsafe characters out of the queue name it is
interpolated into. These four are inert there: `ValidQueueName` accepts any
suffix after its prefix, and the only other consumers of the name are OpenTelemetry
span names. It is never placed in a URL or a SQL identifier.

Fixes #3991

Workflow SDK

Vercel logo npm version License Join the community on GitHub

Workflow SDK makes TypeScript and JavaScript functions durable. It persists workflow progress, retries failed steps, and provides built-in observability. Workflows can suspend without using compute while they wait.

Quick start

Install the SDK in an existing project:

npm install workflow

Configure the integration for your framework. For example, with Next.js:

// next.config.ts
import { withWorkflow } from 'workflow/next';

export default withWorkflow({});

Then start a workflow from an API route, Server Action, or other server-side code:

import { start } from 'workflow/api';
import { onboardUser } from './workflows/onboard-user';

await start(onboardUser, ['hello@example.com']);

Run your app, then open the local observability UI in another terminal:

npm run dev
npx workflow web

Choose your framework in the getting-started guides.

Note

The workflow package includes its full documentation, so coding agents can read version-matched guides locally from node_modules/workflow/docs.

Run anywhere

Local development uses the bundled backend with no configuration. Deploy to Vercel for managed storage, queuing, scaling, and observability. To self-host, use the Postgres backend or implement a custom World.

The Worlds page lists maintainer-curated third-party Worlds, including self-hosted and managed options. Submit your World by updating the Worlds Manifest.

Community

The Workflow SDK community lives on GitHub Discussions, where you can ask questions, share ideas, and show what you have built.
