@workflow/web-shared

Workflow Observability UI primitives. See Workflow SDK for more information.

Usage

This package contains:

• pre-styled, prop-driven UI components (no data fetching)

If you want a full observability experience with server actions already wired, take a look at @workflow/web instead.

It comes with pre-styled UI components that accept data + callbacks:

import { TraceViewer } from '@workflow/web-shared';

export default function MyRunDetailView({ run, events, fetchSpanDetail }) {
  return (
    <TraceViewer
      run={run}
      events={events}
      sidebarData={{ run, events, fetchSpanDetail }}
    />
  );
}

Server actions and data fetching are intentionally not part of web-shared. Implement those in your app and pass data + callbacks into these components. If you need world run helpers, use @workflow/core/runtime.

Security notice: If you implement server-side data fetching using @workflow/world-vercel or similar backends, ensure that user-supplied IDs (runId, stepId, etc.) are validated before passing them to world functions. The server actions in @workflow/web do not include authentication — see that package's README for details on securing self-hosted deployments.

Styling

In order for tailwind classes to be picked up correctly, you might need to configure your NextJS app to use the correct CSS processor. E.g. if you're using PostCSS with TailwindCSS, you can do the following:

// postcss.config.mjs in your NextJS app
const config = {
  plugins: ['@tailwindcss/postcss'],
};

export default config;
