fix(storybook-addon): Issue 993 proxy errors by akornmeier · Pull Request #994 · nuxt-modules/storybook

akornmeier · 2026-01-07T13:03:36Z

Resolves: Nuxt 4 http proxy errors on fresh nightly install #993
Related: feat!: add Storybook 10 and Nuxt 4 support #981

Summary of Changes

Fix: Storybook Proxy Configuration

Added @unhead/vue dependency and explicit Unhead initialization in Storybook preview for compatibility with plugins that rely on useHead() (such as @nuxt/ui and others)
Updated the Storybook Vite proxy configuration to dynamically use the correct dev server URL
Excluded the /builds/meta route from proxying to prevent unnecessary 404 errors

Dependency Fixes

Added pnpm override to pin h3 to 1.15.4 to prevent version conflict between h3 v1 (Nuxt runtime) and h3 v2 RC (resolved by nuxt-site-config), which caused prerender errors

These changes prevent the errors that created the memory-leak in the module that crashed-out the proxy server.

Thanks, there is a lot of things going on in this PR. Could you please split it in more manageable parts (i.e. the nuxt-ui-pro migration can be split of, same for the revamp of the playground).

Thanks, there is a lot of things going on in this PR. Could you please split it in more manageable parts (i.e. the nuxt-ui-pro migration can be split of, same for the revamp of the playground).

I was just doing that exact thing. I'll revert the wholesale change to playground/, I agree that was a little ambitious for this proxy fix.

I noticed an issue or two mentioning updating some of the examples, maybe that is a better place to add something like I did for playground (and in a different PR).

I had to change the nuxt-ui-pro dep due to the changes in playground, so I can back that out too.

I will push an update soon.

tobiasdiez · 2026-01-07T15:40:05Z

Thanks! It's good to have those changes as well (in particular the nuxt-ui upgrade), just transfer them to a new PR please.

The revert commit 4494e7e accidentally removed the addon-docs configuration, causing autodocs pages to fail with 'Couldn't find story matching' error. - Add @storybook/addon-docs to addons array in .storybook/main.ts - Add @storybook/addon-docs as devDependency

@tobiasdiez / @chakAs3 - I have split the original PR into 3 more focused issue/PRs. I feel confident the memory leak and dependency version issues have been resolved. Here are the related PRs that should complete the Storybook 10.x + Nuxt 4.x upgrade.

@tobiasdiez / @chakAs3 - I have split the original PR into 3 more focused issues/PRs. The memory leak and dependency version issues have been resolved. Here are the related PRs that should complete the Storybook 10.x + Nuxt 4.x upgrade.
* [fix(docs): upgrade to @nuxt/ui v4 with Tailwind CSS v4 #996](https://github.com/nuxt-modules/storybook/pull/996)

* [docs: align version requirements for Nuxt 4.x and Storybook 10.x #998](https://github.com/nuxt-modules/storybook/pull/998)

Checking in on these updates. I'd love to get the Nuxt + Storybook plugin aligned with the current versions of both tools. Is there anything you need me to do with these 3 PRs to merge them and cut the new v10 release?

I will do final review and test before merging them then i ll cut 10v release

rpauls-scayle · 2026-01-27T12:24:44Z

Hi @chakAs3 / @akornmeier is there any additional assistance required for the v10 release i can support with?

chakAs3 · 2026-01-27T16:59:41Z

@akornmeier @rpauls-scayle it is crashing when i run pnpm dev. i could not test using the main playground
either pnpm example:showcase:dev

rpauls-scayle · 2026-01-28T11:05:41Z

Can verify, running pnpm dev from this branch, results in Storybook crashing during startup of the dev server, same running pnpm example:showcase:dev:

pnpm dev

@akornmeier is one of your other split out PR a prerequisite for this PR? 🤔

akornmeier · 2026-01-28T12:04:16Z

Yeah, it was all working as a single PR. I can take a look today and see which part it is missing for this main path.

@chakAs3 / @akornmeier I had another quick look today:

Looks like the startup issues with ERR_REQUIRE_ESM have simply been caused by trying to run all relevant dev command with Node v20. Running with Node v22 or Node v24 resolves these.

So we might want to consider updating the minimum Node version to at least >=22.0.0.
This is relevant for the following two package.json files:

packages/nuxt-module/package.json
packages/storybook-addon/package.json

In regard to running pnpm example:showcase:dev we're currently getting a 404 after startup if we simply open http://localhost:3000 in the browser.

This appears to be expected, as we do not have a default index.vue within examples/showcase/pages that would be used for /. If we simply open http://localhost:3000/HelloWorld, the application works without issues.

rbenzazon · 2026-01-30T11:24:59Z

Hello, Thanks for the support ! I would like to know if I can use a nightly build of some sort to test the fix for the proxy errors, or do I need to use the commit as a npm dep?, I have a fresh project with updated version and I can't make storybook work, since my project is at an early stage I don't mind testing if it helps me start building my stories
Regards

braedenfoster · 2026-03-01T21:26:23Z

Is anyone working on a fix for resolving the startup issues in this PR? Seems to have stalled.

chakAs3 · 2026-03-02T10:04:08Z

@akornmeier any chance to get it fixed ?

huang-julien · 2026-03-22T12:06:58Z

 import { $fetch } from 'ofetch'
+import { createHead as createClientHead } from '@unhead/vue/client'
+// The headSymbol is just the string "usehead" used for Vue's provide/inject
+const headSymbol = 'usehead'


Unhead exports headSymbol, it's probably better to use the exported var in case unhead changes to an actual Symbol() in the future

But i'm not sure how this relates to the proxy issues

## Summary - `pnpm run dev` 実行時に `/_nuxt/@vite/client` などが 500 を返し、SPA がブートストラップできない事象の暫定対応 - `nuxt.config.ts` の `modules` 配列から `@nuxtjs/storybook` を一旦外す ## 背景・原因 `@nuxtjs/storybook@9.0.1` の peer dependency は `storybook ~9.0.5` だが、本プロジェクトは `storybook@10.3.5` を使用しているため、Storybook 10 の API 変更に追従できず、モジュールが登録した `/_nuxt/*` Vite proxy が機能しない（接続先が listen しない → ECONNREFUSED）。 upstream で修正 PR ([nuxt-modules/storybook#994](nuxt-modules/storybook#994)) がレビュー中のため、それがマージ・リリースされるまでの暫定回避。 ## 影響 - ❌ `pnpm dev` 起動時に Storybook も同時起動する機能 → 動かなくなる（もともと壊れていた） - ✅ Storybook 単独起動 (`pnpm storybook`) → 引き続き利用可能 - ✅ CI の `pnpm run build-storybook` → スタンドアロンで動くため影響なし - ✅ デプロイされる Storybook サイト → 影響なし ## 恒久対応追跡 issue: #590 ## Test plan - [x] `pnpm run dev` で SPA が起動し、`/auth/login` `/auth/user-register` が表示される - [x] `pnpm run lint` 通過 - [ ] `pnpm storybook` が単独起動できることを確認 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
