Migrate `@workflow/web` from Next.js to React Router v7 #1005

TooTallNate · 2026-02-11T20:11:42Z

Summary

Replace Next.js App Router with React Router v7.13.0 framework mode (Vite-based), eliminating the large next dependency from the web, CLI, and workflow metapackages
Serve the web UI in-process from the CLI via Express instead of spawning next start as a child process
Switch RPC transport from JSON to CBOR to preserve binary data types across the wire
Replace nuqs URL state management with React Router's useSearchParams
Replace Next.js server actions with an RPC resource route (/api/rpc) and a thin CBOR-based client

Motivation

The next package is ~300MB installed and was the single largest dependency in the monorepo. It also required spawning a separate child process from the CLI to run the o11y web server, adding complexity around process lifecycle management, port readiness polling, and environment variable forwarding.

With React Router framework mode, the web package builds to a standard Express-compatible server bundle that the CLI can import and serve directly in its own process.

What changed

Framework swap (@workflow/web):

next.config.ts / postcss.config.mjs → react-router.config.ts / vite.config.ts
src/ directory → app/ directory (React Router convention)
src/app/layout.tsx + layout-client.tsx → app/root.tsx
src/app/page.tsx → app/routes/home.tsx
src/app/run/[runId]/page.tsx → app/routes/run-detail.tsx
Path alias @/ → ~/
Removed all 'use client' / 'use server' directives

Data transport:

Server actions → RPC resource route at /api/rpc with CBOR encoding
CBOR preserves Uint8Array and other binary types natively (no base64 overhead)
Stream reading → dedicated /api/stream/:streamId resource route

URL state:

nuqs (useQueryState) → useSearchParams from react-router

Fonts:

next/font/google → Geist .woff2 files referenced directly from node_modules/geist via @font-face in CSS

CLI integration (@workflow/cli):

import('@workflow/web/server').then(m => m.startServer(port))
No child process, no readiness polling, no cleanup handlers

Radix UI compatibility:

onSubmit preventDefault on AlertDialogContent and SheetContent to prevent Radix's internal <form method="dialog"> from triggering React Router route actions
Catch-all action on root route for any stray POSTs

Dependencies removed

next, swr, nuqs, @tailwindcss/postcss

Dependencies added

react-router / @react-router/dev / @react-router/node / @react-router/express (all 7.13.0)
express, vite, @tailwindcss/vite, cbor-x, isbot, cross-env
geist (devDep)

Only console.error for genuine server-side failures (5xx). API-level client errors (4xx), run-not-found errors, and unrecognized errors from world backends are not logged server-side — the error is returned to the caller for handling.

Move the stray-POST handling from individual route actions to a single catch-all action on root.tsx. This covers all current and future routes without needing per-route action stubs.

Switch the RPC layer from JSON to CBOR encoding to preserve binary data (Uint8Array) across the wire. CBOR natively handles binary types without base64 overhead. Hydration (deserializing input/output/eventData from binary format to JS values) stays server-side for now. Making @workflow/core's hydration code browser-safe requires extracting it from the serialization module which has deep Node.js dependencies (Buffer, AsyncLocalStorage, child_process, etc.). This will be addressed as a prerequisite when e2e encryption lands. - Add cbor-x as runtime dependency - RPC route: encode responses as CBOR - RPC client: send/receive CBOR with proper Content-Type headers - Server actions: hydrate data before CBOR encoding (no JSON round-trip needed since CBOR preserves all JS types) - Hydration errors are caught and return raw data instead of crashing

- Add error handling for malformed CBOR/JSON request bodies (400) - Remove unused readStreamServerAction import from RPC route - Validate streamId format and startIndex parameter in stream route - Decode CBOR error body in RPC client for better error messages - Remove duplicate static file middleware from server/app.ts - Fix dev script to use react-router dev instead of node server.js

Vite's SSR build externalizes certain packages instead of bundling them. When @workflow/web is installed from npm (not in the monorepo), these externalized packages must be in dependencies to be available at runtime. Move all Radix UI, lucide-react, class-variance-authority, clsx, tailwind-merge, date-fns, next-themes, sonner, @xyflow/react, and workspace packages to dependencies. Add react/react-dom as peerDependencies.

Use ssr.noExternal=true in Vite config to bundle all dependencies into the server build. This means @workflow/web only needs express at runtime — all UI dependencies (Radix, lucide-react, etc.) are compiled into the server bundle. Keeps the installed package small.

…transport Move observability hydration to the shared serialization-format + web/cli-specific hydration modules, shift web UI hydration to the client side, and align RPC/CBOR behavior to reduce merge conflict risk with PR #1005/#1015 while fixing binary payload rendering in observability views.
