* feat(web): port v1.5 dev backend (vite-hono-plugin + sandbox + remote-server bootstrap) Ports the v1.5 in-process dev backend into v2 so `npm run dev` serves the Hono remote-server (`/api/*`) alongside the Vite-served browser app. Without this, the browser-side `createRemoteTransport` had nothing to talk to during local development. Adds under `clients/web/server/`: - vite-hono-plugin.ts (Hono middleware on the Vite dev server; gated to `apply: 'serve'` and skipped when `process.env.VITEST` is set so it stays inert in vitest/storybook runs) - sandbox-controller.ts (standalone HTTP server for the MCP Apps sandbox) - web-server-config.ts (env parsing + initial-config payload + banner; `autoOpen` defaults off under VITEST so test runs don't shell out to `open`) - server.ts (standalone Hono prod server for the future v2 launcher, #1246) - start-vite-dev-server.ts (in-process Vite starter for the future launcher) - vite-base-config.ts (shared optimizeDeps exclusions) Wires `honoMiddlewarePlugin(buildWebServerConfigFromEnv())` into `vite.config.ts` with `apply: 'serve'`. Adds the `open` dependency and a DOM lib + `@inspector/core/*` path alias to `tsconfig.node.json` so the dev-backend files type-check alongside vite.config.ts. Coverage: web-server-config.ts (100% lines), sandbox-controller.ts (91% lines), and vite-base-config.ts (100%) all clear the per-file gate. The Vite plugin, prod server, and dev-server starter are excluded from coverage as runtime glue exercised by `npm run dev` end-to-end (callers covered separately; their logic lives in core/mcp/remote/node, which integration tests already exercise). Closes #1320. Unblocks #1244 (Wire App.tsx) — its test plan can now run end-to-end. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(web/server): address PR review feedback on the dev-backend port - sandbox-controller: resolve start() with empty values on listen error (e.g. EADDRINUSE on a fixed MCP_SANDBOX_PORT) instead of leaving the promise pending forever. Without this, the Vite plugin's `await sandboxController.start()` could hang the entire dev backend on a port collision. Banner now silently omits the sandbox line; getUrl() keeps returning null. Adds a regression test exercising the EADDRINUSE path against a real socket. - vite-hono-plugin: listen for `error` and `close` on the incoming request stream (in addition to `end`) so an aborted POST/PUT (browser navigates mid-upload) doesn't leak the middleware indefinitely. - vite-hono-plugin: add a `.catch()` to the initial `pump()` kickoff so a sync throw before the first `await reader.read()` can't surface as an unhandled rejection. - sandbox_proxy.html: drop the stale CSP comment — v1.5's sandbox HTTP server never set CSP either; this PR doesn't regress anything. Replace with the actual isolation model (iframe sandbox attribute + origin allowlist) so future readers don't assume a CSP header is enforced. - Hoist `WebServerHandle` to a shared `server/types.ts` so the future launcher port (#1246) doesn't need to pick one of two duplicate declarations. - Extract `resolveAutoOpen()` helper out of the triple-nested ternary in `buildWebServerConfigFromEnv` for legibility, with the three-way logic documented in one place. - Add an inline comment explaining why `webServerConfigToInitialPayload` falls back to streamable-http for unknown discriminators (forward-compat with future SDK transports) rather than throwing.
