feat: serve the client UI as devframe remote assets via @nuxt/devtools-assets - #1071
Conversation
…s-assets The built client SPA no longer ships inside the @nuxt/devtools tarball. It is published as the version-locked @nuxt/devtools-assets package and declared as a devframe remote-assets source: a locally installed copy is served with zero network (monorepo, e2e, offline/air-gapped installs), otherwise files stream on demand from a CDN mirror of npm into an on-disk cache. The client build is now mount-path portable — hash routing plus relative asset URLs with a location-derived runtime baseURL — so devframe's ctx.views.hostStatic serves the directory verbatim and the serve-time __NUXT_DEVTOOLS_BASE__ index.html rewrite is gone. Connection meta is mounted on the client base like the hub does for its devframes, so a direct navigation to /__nuxt_devtools__/client/ now discovers the RPC endpoint too. A new clientAssets module option overrides the source: a directory path serves a local build, false skips mounting (used by the dogfooding client app itself).

Use the workspace catalog for @nuxt/devtools-assets.
Both dependency declarations use workspace:*. Replace them with catalog:<name>. Add the matching asset package version to the appropriate catalog in pnpm-workspace.yaml.
packages/devtools/package.json#L35-L35: reference the optional peer dependency through the catalog.packages/devtools/package.json#L88-L88: reference the development dependency through the same catalog entry.
As per coding guidelines, reference dependency versions using catalog:<name> in package manifests instead of pinning raw versions; add missing versions to the appropriate catalog in pnpm-workspace.yaml.

…client by rootDir The only real consumer was the client app itself opting out of the static mount. The module already knows its own client app's directory, so detect that rootDir instead — the client app only exists in this repo, never next to the published package.
Each package's prepack ran its own build in isolation, never building its workspace dependencies. `pnpm -r publish` skips packages whose version already exists on npm, so a skipped dep's dist could be absent when a dependent package's prepack runs — e.g. @nuxt/devtools-assets' client generate consumes @nuxt/devtools-kit. Route each prepack through `turbo run build --filter=<self>` so turbo's dependsOn graph builds workspace deps in the correct order and cache- restores shared ones. Also scope @nuxt/devtools#build to @nuxt/devtools-kit only, so packing the module no longer regenerates the uncacheable client it no longer ships.
The DevTools client is now hosted by devframe / the Vite DevTools hub, so Nuxt DevTools no longer creates or manages its own client iframe. Drop the dead v3 embedding path: - `view/client.ts`: `getIframe`, `syncClient`, `waitForClientInjection`, the `iframe` local and the `devtools:navigate` route-persistence handler - the `__NUXT_DEVTOOLS_VIEW__` injection protocol (host guard, window global type, and the client-side `setClient` defineProperty) - `view/state.ts` frame-geometry storage and the dead client-side `useDevToolsFrameState`/`useDevToolsPanelsState` twins - `NuxtDevtoolsHostClient.getIframe`/`syncClient`/`app.frameState`, the `DevToolsFrameState` and `NuxtDevtoolsGlobal` types - the `iframeProps` module option (only the removed iframe consumed it) The current host<->client bridge (`__NUXT_DEVTOOLS_HOST__` + `connectParent`), the component inspector, and popup mode (`__NUXT_DEVTOOLS_DISABLE__`) are unaffected. BREAKING CHANGE: the `iframeProps` module option is removed; the client iframe is now managed by the Vite DevTools hub.
Description
The built client SPA is the bulk of the
@nuxt/devtoolstarball. Following devframe's remote assets pattern (the same one devframe's own plugins use, e.g.@devframes/plugin-data-inspector--assets), the client now ships as a separate, version-locked@nuxt/devtools-assetspackage and is no longer bundled into@nuxt/devtools.How it resolves
Per devframe's resolution order, the client UI is served from:
@nuxt/devtools-assets(zero network — the monorepo/e2e flows via the workspace dev-dependency, and offline/air-gapped installs via the optional exact-version peer dependency), thenMount-path portable client
Serving through
ctx.views.hostStaticrequires the SPA to be servable verbatim — the previous serve-time__NUXT_DEVTOOLS_BASE__index.htmlrewrite is gone. The production client build is now mount-path portable:router.options.hashMode) keeps the document URL at the mount root, so relative URLs always resolve (and a reload now restores the active tab);copy-client.mjspost-processes the generated HTML shells: asset URLs become relative (./_nuxt/…) and the inline runtime-configbaseURLbecomes alocation-derived expression (Nuxt cannot generate with a relative base directly — the build keeps the placeholder and the copy step rewrites it, failing loudly if Nuxt's serialization changes).Connection meta is now also mounted on the client base (as the hub does for each devframe it installs), so a direct navigation to
/__nuxt_devtools__/client/discovers the RPC endpoint — previously only the hub-embedded flow connected.Dogfooding
The
nuxi dev clientflow (where the app under development is the client) is detected byrootDir— the module skips the static mount and points the dock at the live app's own base. No module option needed; the client app only exists in this repo, never next to the published package.Nightly releases
The assets package name is derived from the module's own peer-dependency entry, so nightly builds (renamed via
npm:<name>-nightly@<version>alias ranges byscripts/bump-nightly.ts) fetch their matching nightly assets automatically.Notes
@nuxt/devtools-assetsmust be published together with each@nuxt/devtoolsrelease (bumpp -r --allkeeps versions in lockstep; the release workflow publishes all workspace packages). Until the first publish, only locally-installed resolution serves the UI — devframe logs a DF0059 warning and falls through gracefully otherwise.turbo: the assets build task is uncacheable (its inputs —packages/devtools/client/**— live outside the package) and explicitly depends only on@nuxt/devtools-kit#buildto avoid a cycle with@nuxt/devtools's dev-dependency on the assets package.test:e2e:builtpass; the portable build was manually verified served verbatim at an arbitrary mount path and through a playground dev server (RPC connects, hash router works), and the dogfooding dev server serves the live client unshadowed. The*:deve2e suite fails identically on unmodifiedmainin this sandbox (the hub never mounts the client iframe headlessly here), so those failures are environmental — CI should tell.This PR was created with the help of an agent.
