fix(auth): rebuild nuxthub postgres adapters per request by onmax · Pull Request #295 · nuxt-modules/better-auth

onmax · 2026-03-24T20:01:57Z

Closes #294

Summary

Hyperdrive-backed NuxtHub PostgreSQL auth requests were reusing state across Worker requests in two places: the module-level Better Auth singleton and the generated Drizzle client for the NuxtHub PostgreSQL adapter. Direct @nuxthub/db access still worked, but Better Auth session or user reads could intermittently fail on deployed Workers.

This patch keeps the existing cache for non-database setups, but rebuilds database-backed auth instances per request and generates a fresh Hyperdrive postgres-js client with prepare: false for the NuxtHub PostgreSQL path.

Scope

Rebased on current main. The @nuxthub/db import-resolution work that was part of earlier revisions is now dropped — #305 landed a different fix (Nitro externals) that supersedes it.

Two smaller, unrelated cleanups are being split out into their own PRs:

nitropack/runtime → #imports migration across 3 server runtime files
test/cases/plugins-type-inference fixture restore

Bug	nuxt-better-auth-294	Builds; deployed Hyperdrive auth reads can fail
Fix	nuxt-better-auth-294-fix	Builds; deployed Hyperdrive auth reads stay stable

CLI Reproduction

git clone --depth 1 --filter=blob:none --sparse https://github.com/onmax/repros.git
cd repros && git sparse-checkout set nuxt-better-auth-294
cd nuxt-better-auth-294 && pnpm i && pnpm build

The runtime bug requires a real Cloudflare Hyperdrive binding. After deploy, verify the bug repro by hitting /api/db-check, signing up, and then repeating authenticated /api/auth-check requests.

Verify fix

git sparse-checkout add nuxt-better-auth-294-fix
cd ../nuxt-better-auth-294-fix && pnpm i && pnpm build

Hey @onmax

Here's few issues I found:

queries are still failing when using database hooks (which means it may happen without this hooks but this errors are occasional I believe this is related to point 2 I mentioned below):
From repro:

POST https://nuxthub-better-auth-repro.jdsolanki0001.workers.dev/api/auth/sign-in/email - Ok @ 3/25/2026, 12:52:43 PM
  (error) [request error] [unhandled] [POST] https://nuxthub-better-auth-repro.jdsolanki0001.workers.dev/api/auth/sign-in/email
 {
  message: 'Failed query: select "id", "expires_at", "token", "created_at", "updated_at", "ip_address", "user_agent", "user_id" from "session" limit $1\n' +
    'params: 1',
  statusCode: 500
}

Screenshot

It seems our code is not optimised enough because we're getting Error: Worker exceeded CPU time limit error. Try login multiple times and you will receive 503 error in network tab and you may get full page error as attached below

page screenshot

From my actual app:

POST https://nuxtstart.jdsolanki0001.workers.dev/api/auth/sign-in/email - Ok @ 25/3/2026, 12:23:18 pm
  (error) [request error] [unhandled] [POST] https://nuxtstart.jdsolanki0001.workers.dev/api/auth/sign-in/email
 {
  message: 'Failed query: update "user" set "updated_at" = $1, "last_sign_in_at" = $2 where "user"."id" = $3\n' +
    'params: 2026-03-25T06:53:20.965Z,2026-03-25T06:53:20.965Z,NaRranaO7OEatauhsvvvN8ZLKXXfNqHa',
  statusCode: 500
}

Tried pnpm i https://pkg.pr.new/@onmax/nuxt-better-auth@295 in my other repo which uses nuxt layers but it seems pkg pr is outdated because it isn't able to identify auth config I have in one of my layers.
```
ERROR  [nuxt-better-auth] Missing server/auth.config.ts - create with defineServerAuth()
```

Hence using github:nuxt-modules/better-auth#pull/295/head for now

related: cloudflare/workers-sdk#6179

onmax · 2026-03-26T09:29:05Z

@jd-solanki Please try again when you have a moment. I’ve pushed a fix for the issue on our side.

jd-solanki · 2026-03-27T05:20:29Z

Hey @onmax

sorry I was not able to test it yesterday.

I tried latest commit and now we have initial installation issue where we first install the packages:

Even after this error when I run dev command we get error in browser:

Cannot find package 'nitropack' imported from /private/tmp/nuxthub-better-auth/.nuxt/better-auth/database.mjs

screenshot

I also check installed modules just to be sure:

NOTE: I pushed latest commit of this PR to my repro if you want to try it locally: https://github.com/jd-solanki/nuxthub-better-auth-repro?rgh-link-date=2026-03-24T18%3A52%3A51.000Z

onmax · 2026-03-27T07:46:09Z

@jd-solanki I pushed another fix and the fresh pkg.pr.new package is ready here:

https://pkg.pr.new/nuxt-modules/better-auth/@onmax/nuxt-better-auth@9a4ad00

Please use this owner/repo-qualified URL instead of the compact @295 alias. I verified that this long URL resolves to the current package build for this PR.

I tested it against your repro locally and I could no longer reproduce the nitropack import error. Could you try again and let me know if pnpm install or pnpm dev still fails, ideally with the exact new error output?

jd-solanki · 2026-03-29T13:54:41Z

Hey @onmax

I tried latest commit but still facing following:

ni hung up
If I kill (ctrl + c) the ni hung up and run nr dev then end up with Cannot find package 'nitropack' imported from /private/tmp/nuxthub-better-auth-repro/.nuxt/better-auth/database.mjs
Same SQL query failures

I updated package lock to exact commit this time so now if you pull latest changes and run ni you might face the same error.

BTW it's surpring to me that your ni didn't froze 🤔

I request you to also validate when you have in your node_modules dir because for me pkg.pr was not installing latest changes you make in this PR.

For example, with pkg.pr command ni https://pkg.pr.new/@onmax/nuxt-better-auth@29, node_modules/@onmax/nuxt-better-auth/dist/runtime/server/utils/auth.js path don't have:

import { useRuntimeConfig } from "nitropack/runtime";

instead of

import { useRuntimeConfig } from "#imports";

onmax · 2026-03-29T15:36:05Z

I retried this from a fresh /tmp repro and found that the compact pkg.pr.new alias can be stale for this package.

Please avoid the github:... install for this check. With pnpm 10, git-hosted packages can fail because they need a prepare step.

Please also use the owner/repo-qualified pkg.pr.new URL below instead of the compact @295 alias:

rm -rf node_modules .nuxt
pnpm install https://pkg.pr.new/nuxt-modules/better-auth/@onmax/nuxt-better-auth@9a4ad00
pnpm dev

I verified this long URL resolves to the current package build for this PR.

If it still fails, please paste:

the exact install command you used
the full new error output

jd-solanki · 2026-04-11T05:45:48Z

Steps:

Made a fresh clone
Ran pnpm install https://pkg.pr.new/@onmax/nuxt-better-auth@295
Ran nr dev
Opened localhost:3000 in browser

Error

Cannot find module '/private/tmp/nuxthub-better-auth-repro-1/.nuxt/hub/db.mjs' imported from /private/tmp/nuxthub-better-auth-repro-1/.nuxt/better-auth/database.mjs

With new changes nuxt prepare command fails, cloudflare build fails but works with node-server runtime:
