uuid npm package changelog v12 v13 breaking changes

💡 Result:

uuid (uuidjs/uuid) breaking changes

v12.0.0 (2025-09-05)

  • Removed CommonJS support (ESM-only). [1]
  • Dropped Node.js 16 support (requires Node 18+). [1]
  • Updated build/tooling to TypeScript 5.2 (can affect TS consumers/build pipelines). [1]

v13.0.0 (2025-09-08)

  • Changed package exports resolution so the browser build is the default. This was done because v12 inadvertently made the Node build the default; v13 renames the Node-specific build to dist-node and restores browser-first export selection. [1][2]

Verify uuid v13.0.0 breaking changes — upgrade requires careful review.

This bumps uuid from ^11.0.5 to ^13.0.0, passing through two major versions with breaking changes:

  • v12.0.0: Removed CommonJS support (ESM-only), dropped Node.js 16 (requires Node 18+), updated to TypeScript 5.2
  • v13.0.0: Changed package exports; browser build is now the default (renames Node-specific build to dist-node)

Confirm that the codebase supports ESM-only, meets the Node 18+ requirement, and handles the export path change correctly (any explicit imports from dist or dist-node paths will break).

jsdom v28 breaking changes changelog migration

💡 Result:

jsdom v28.0.0: breaking/behavior changes & what to migrate

1) Resource loading customization was overhauled (main migration item)

jsdom v28 changes how you customize networking/resource fetching (“Overhauled resource loading customization… new API”). You should review any code that previously customized subresource fetching, proxies, user agents, request blocking, etc. and update it to the new resources-based configuration and interceptors API described in the README. [1] [2]

New shape (v28):

  • Use resources: { userAgent, dispatcher, interceptors } on new JSDOM(html, options) (and it also applies to the initial request for JSDOM.fromURL()). [2]
  • Interception is done via requestInterceptor(...), which can return an undici Response to short-circuit the request. [2]
  • Limitation: resource-loading customization is ignored for synchronous XMLHttpRequest. [2]

2) <iframe> / <frame> loading behavior changes

  • Added MIME type sniffing to <iframe> and <frame> loads. (This can change what content type gets assumed/parsed.) [1]

3) WebSocket behavior change/regression

  • Regression noted in v28: WebSockets “no longer correctly throttled to one connection per origin” (due to an upstream undici bug). If your tests relied on the old throttling behavior, re-check them. [1]

4) Observable fetch/referrer/event behavior fixes (may affect tests)

  • Document referrer across redirects is now set to the initiating page, not the last redirect hop. [1]
  • <iframe>, <frame>, and <img> (with canvas installed) now fire load (not error) on non-OK HTTP responses. [1]
  • XHR/WebSocket requests are now interceptable by the new customizable resource loading (except synchronous XHR). [1]

5) Runtime requirement check (before upgrading)

Confirm your Node.js version matches jsdom’s supported engines for v28: ^20.19.0 || ^22.12.0 || >=24.0.0. [3]

jsdom v27 breaking changes API changes

💡 Result:

jsdom v27: notable breaking/API changes (vs v26.1.0)

  • Node.js requirement raised: Node.js v20+ is the minimum supported runtime. [1]

    • Also note: v27.0.1 further (and inadvertently) raised the effective minimum to v20.19.0+ / v22.12.0+ / v24.0.0+ due to dependency constraints. [2]
  • VirtualConsole API changes: [1]

    • virtualConsole.sendTo()renamed to virtualConsole.forwardTo()
    • omitJSDOMErrors option → replaced by jsdomErrors option (used with forwardTo())
    • "jsdomError" event shape/behavior updated (documented type, some errors no longer emitted, console output streamlined)
  • Events / DOM behavior changes: [1]

    • element.click() now fires a PointerEvent instead of a MouseEvent
    • “Certain events” are now passive by default
  • Cookies / secure-context behavior change (tough-cookie upgrade):

    • http://localhost/ is treated as a secure context, so Secure cookies may be returned for localhost. [1]
  • Selector engine swap: nwsapi@asamuzakjp/dom-selector, which can affect selector edge-cases/feature-detection. [1]

  • <input pattern> regex flag change: pattern is compiled with the v flag instead of u. [1]

  • Window object shape changes: various Window properties changed from data properties to accessor properties, plus other named-property conformance fixes (can break monkey-patching/introspection). [1]

  • document.createEvent() compatibility change: now accepts a more-correct set of event names (code relying on previously-accepted names may break). [1]

  • CSS/Computed style differences:

    • User-agent stylesheet updated to be derived from the HTML Standard (may change getComputedStyle() results). [1]
    • cssstyle upgrade changes CSSStyleDeclaration behavior/properties (could affect style parsing/serialization expectations). [1]

Review jsdom v28 breaking changes before merging — resource loading API overhauled, multiple DOM/event behavior changes.

jsdom v28.0.0 exists on npm and is the latest version. However, v27 is not skipped (versions 27.0.0–27.4.0 are available). More importantly, upgrading from v26 to v28 introduces multiple breaking changes requiring test verification:

v28 breaking changes:

  • Resource loading customization overhauled: New resources: { userAgent, dispatcher, interceptors } API with requestInterceptor() required if tests customize networking, proxies, or request blocking. Synchronous XHR is not interceptable.
  • <iframe> and <frame> now apply MIME type sniffing (may change parsed content type).
  • WebSocket throttling regression: no longer throttled to one connection per origin.
  • Document referrer, load/error event behavior changes.
  • Node.js engine requirement: ^20.19.0 || ^22.12.0 || >=24.0.0.

v27 breaking changes (also affecting this upgrade):

  • VirtualConsole API renamed: sendTo()forwardTo(), omitJSDOMErrorsjsdomErrors.
  • element.click() fires PointerEvent instead of MouseEvent.
  • Selector engine swap: nwsapi@asamuzakjp/dom-selector (edge cases may differ).
  • Window object properties changed from data to accessor properties (affects introspection).
  • User-agent stylesheet updated (affects getComputedStyle() results).
  • Input pattern regex now uses v flag instead of u.

Verify test suite compatibility, especially resource loading mocks and VirtualConsole usage.

apps/web/src/env.ts (1)

10-53: ⚠️ Potential issue | 🔴 Critical

Add server-only guard to lib/api.ts to prevent client-side imports that crash at runtime.

Client components (user-fetcher.tsx, componentWithTest.tsx) actively import api from lib/api.ts, which imports env.ts. On the client, required fields like GITHUB_CLIENT_ID, GITHUB_CLIENT_SECRET, and DATABASE_URL are undefined, causing envSchema.parse() to throw immediately when the module loads.

Add import "server-only"; at the top of lib/api.ts to statically prevent client imports, or alternatively add it to env.ts.

apps/web/src/components/Navbar.tsx (1)

6-8: ⚠️ Potential issue | 🟠 Major

Hardcoded user — replace with session data from useSession.

The user object is a static placeholder. This should be replaced with the actual authenticated user from the NextAuth session:

import { useSession } from "next-auth/react";
// inside component:
const { data: session } = useSession();
const user = session?.user;

Otherwise the Navbar always displays "Hi, John Doe!" regardless of who is logged in.

packages/ui/src/components/AuthWithSocialForm/AuthWithSocialForm.tsx (1)

56-71: ⚠️ Potential issue | 🟡 Minor

Stale JSDoc reference to removed NextImage prop.

Line 62 in the AuthWithSocialFormProps example still references NextImage: Image, which has been removed from the public API.

In `@apps/web/next.config.ts`:
- Around line 13-16: remotePatterns currently uses new URL(...) which either
hardcodes a single avatar path or disallows query strings; replace those new
URL(...) entries with object-form patterns so GitHub avatar URLs with queries
are allowed. Specifically, change the avatars entry to an object like {
protocol: "https", hostname: "avatars.githubusercontent.com", pathname: "/u/**"
} and change the raw GitHub entry to { protocol: "https", hostname:
"raw.githubusercontent.com", pathname: "/prebuiltui/**" } so dynamic user IDs
and query params (e.g. ?v=4) are accepted by Next.js image optimization.

In `@apps/web/package.json`:
- Line 22: The package entry using `@auth/prisma-adapter` is incompatible with the
project's next-auth v4 dependency; either replace the adapter with
`@next-auth/prisma-adapter` to match next-auth v4 or upgrade next-auth to v5
(Auth.js) to keep `@auth/prisma-adapter`@^2.11.1—update package.json dependencies
accordingly and run install to ensure types and runtime adapter interfaces align
(adjust any import paths referencing `@auth/prisma-adapter` or next-auth as
needed).
- Around line 50-51: The package.json currently pins "next" to 16.1.6 while
"next-auth" (next-auth / Auth.js v4) is incompatible with Next.js 16; change the
dependency set to a compatible pair: downgrade "next" to a supported 15.x
release (e.g., set "next" to a 15.x semver) so it matches next-auth v4's peer
requirements, keep "next-auth" at the existing v4 range, and update
package-lock/yarn.lock by reinstalling to lock the correct versions; do not
upgrade to next-auth@^5.x or force-install Next.js 16 until Auth.js v5
officially supports Next.js 16.

In `@apps/web/src/app/api/auth/`[...nextauth]/route.ts:
- Around line 137-139: The GoogleProvider call uses a fallback
(env.GOOGLE_CLIENT_ID || "") while GitHubProvider uses env.GITHUB_CLIENT_ID
directly; make them consistent by removing the unnecessary "|| ''" fallback from
GoogleProvider (update the GoogleProvider invocation that references
env.GOOGLE_CLIENT_ID and env.GOOGLE_CLIENT_SECRET) so both providers use the
validated env values directly, or alternatively add the same fallback to the
GitHubProvider (env.GITHUB_CLIENT_ID || "" / env.GITHUB_CLIENT_SECRET ||
"")—prefer removing the fallbacks if env.ts guarantees presence.
- Around line 230-236: The build fails because Session and JWT types don't
include accessToken used in async session({ session, token }: { session:
Session; token: JWT }) in route.ts; add a module augmentation for "next-auth"
and "next-auth/jwt" (declare module ...) to extend Session and JWT with
accessToken?: string (create/update a types/next-auth.d.ts or similar) and
ensure that file is included in tsconfig.json include/typeRoots so TypeScript
recognizes the augmented interfaces.
- Around line 250-336: The signIn callback currently auto-links OAuth accounts
to an existing user when emails match (see signIn, prisma.account.upsert,
prisma.user.update/create), which allows account takeover if an attacker
controls an OAuth provider account with the same email; change the flow to
prevent automatic linking by: 1) stopping automatic upsert/create linking in
signIn when an existing user is found, 2) instead create a pending AccountLink
record or send a verification email/token to the existing user's verified email,
and 3) require the user to confirm the link from an authenticated session (or
verify the token) before calling prisma.account.create/upsert and updating
prisma.user; ensure all codepaths that currently call prisma.account.upsert,
prisma.account.create, and prisma.user.update are gated behind that explicit
verification/confirmation step.
- Line 86: Remove the dead commented-out code "// where: { provider: "google" }"
— it is superseded by the active provider filter immediately below; delete that
commented line in the route handler so only the active provider filtering code
remains and no stale comment confuses future readers.
- Around line 75-109: In authorize, normalize the incoming credentials.email the
same way signup does before using it in prisma.user.findUnique: trim whitespace
and convert to lowercase (e.g., const normalizedEmail =
credentials.email.trim().toLowerCase()) and use that normalizedEmail for the
lookup and any subsequent checks; update references to credentials.email in the
authorize function (including the Credentials validation and
prisma.user.findUnique call) to use the normalized value so lookup behavior
matches signup.
- Around line 345-347: The sign-in page is hardcoded as "/signin"; import ROUTES
from "@/constants/routing" and replace the literal with ROUTES.SIGNIN in the
NextAuth config (where pages.signIn is set) so the route uses the centralized
constant; add the import for ROUTES at the top of the file if missing and update
pages: { signIn: ROUTES.SIGNIN } accordingly.

In `@apps/web/src/app/api/auth/signup/route.ts`:
- Around line 46-48: The current branch returns a distinct 409 response when
existingUser is truthy, enabling user enumeration; change the signup flow so the
handler always returns a uniform response (use the same HTTP status and message)
whether or not existingUser exists. Locate the check that references
existingUser and the NextResponse.json call and replace the specialized 409
branch with a generic response (e.g., 200 and a neutral message like "If this
email is not registered, an account will be created" or a uniform error string)
so callers cannot distinguish registered vs unregistered emails; ensure all code
paths that previously returned different statuses now use the same
NextResponse.json signature.
- Around line 72-83: In the catch block that currently calls
console.error("Signup error:", error) (the catch (error) in the signup route),
stop logging the raw error object directly; instead replace it with a
structured/levelled log that omits sensitive details in production (for example
use a logger.error("Signup error", { message: error?.message }) or conditionally
include error.stack only when NODE_ENV !== 'production'), and ensure Zod errors
are still handled by the existing error instanceof z.ZodError branch (leave that
branch intact and only change the console.error call).
- Around line 34-48: Normalize the incoming email before any DB lookup or
creation: in the POST handler after SignupSchema.parse(body) compute a
normalizedEmail (e.g., trimmed and lowercased) and use that normalizedEmail in
prisma.user.findUnique and in the subsequent prisma.user.create (and any other
references to validatedData.email) so lookups and stored values are consistent;
update any place that reads or writes the user email to use normalizedEmail
rather than validatedData.email (leave SignupSchema and POST signature
unchanged).

In `@apps/web/src/app/layout.tsx`:
- Line 41: The code uses a redundant fallback (|| "http://localhost:3000") when
assigning url from env.NEXT_PUBLIC_SITE_URL in apps/web/src/app/layout.tsx;
remove the dead fallback at both occurrences (the url assignment and the second
occurrence at the other location) and rely on the zod schema default defined in
env.ts (z.url().default("http://localhost:3000")), keeping the value as just
env.NEXT_PUBLIC_SITE_URL so the runtime respects the validated/defaulted value.

In `@apps/web/src/app/signin/page.tsx`:
- Around line 22-37: The onSignIn function currently both sets local UI error
state via setError and throws the same error (throw new Error(...)), which is
redundant because AuthWithSocialForm's handleSubmit will catch that throw
and—since no onError prop is passed—only log it; resolve this by either (A)
removing the throw from onSignIn (stop throwing after setError and return) so
error handling is entirely local, or (B) keep throwing but pass an onError
callback into AuthWithSocialForm that routes the error to the same handler
(e.g., calls setError and prevents reset/onSuccess), and ensure handleSubmit's
behavior (reset/onSuccess) is consistent with the chosen path; update the code
around onSignIn, AuthWithSocialForm usage, and the onError prop to match the
chosen approach.
- Line 68: Replace the hardcoded reset-password string passed to the
resetPasswordLink prop with the centralized ROUTES constant; locate the
resetPasswordLink usage in the SignIn page (page.tsx) and import the ROUTES
object from apps/web/src/constants/routing.ts, then change
resetPasswordLink="/reset-password" to resetPasswordLink={ROUTES.RESET_PASSWORD}
(or the appropriate constant name inside ROUTES) so the route is referenced from
the routing constants.
- Around line 58-62: The error banner rendered when the local variable/prop
"error" is truthy should include accessibility attributes so screen readers
announce it; update the error <div> (the conditional block that renders {error}
in page.tsx within the SignIn page) to add role="alert" (and optionally
aria-live="assertive") to the element so the message is announced when it
appears.

In `@apps/web/src/app/signup/page.tsx`:
- Around line 92-96: The error banner in the signup page JSX currently renders a
div for {error} without accessibility semantics; update the error container in
the signup page component (the div that renders {error} in
apps/web/src/app/signup/page.tsx) to include role="alert" so screen readers
announce the message (mirror the same fix applied to the signin page).
- Around line 22-71: The onSignUp function currently calls setError before
throwing for validation and sign-in errors, but throws inside the try get caught
and cause setError to run twice; to fix, make error-state updates happen in one
place by either (A) moving the pre-validation checks into the try block so all
throws are handled by the catch which sets state once, or (B) stop calling
setError before throwing in the validation and sign-in error paths and let the
existing catch (in onSignUp) call setError once; update the onSignUp function
(and references to signIn result handling) to follow one of these patterns so
setError is invoked only in the centralized catch handler.

In `@apps/web/src/app/workspace/page.tsx`:
- Around line 31-32: Remove the leftover debug fetch and log: delete the
useSession() destructure line ("const { data: session } = useSession();") and
the console.log("SEssion", session) call in the page component; if session-based
behavior is required instead, replace these with proper auth logic (e.g.,
useSession() to gate rendering or redirect) and reference the session variable
where needed rather than leaving it unused.

In `@apps/web/src/components/Navbar.tsx`:
- Around line 28-34: Replace the hardcoded callbackUrl "/" in the onLogout
function with the ROUTES.HOME constant (import ROUTES from
apps/web/src/constants/routing.ts) and update the signOut call in async function
onLogout to use callbackUrl: ROUTES.HOME; also add user-facing feedback in the
catch block (e.g., trigger the app's toast/error notification method) instead of
only console.error so users see logout failures.

In `@apps/web/src/constants/pdf.ts`:
- Around line 14-17: Add JSDoc blocks for PAGE_WIDTH_PT and PAGE_HEIGHT_PT
matching the style of LETTER_WIDTH_PX and LETTER_HEIGHT_PX: document that these
constants represent US Letter dimensions in points (pt) calculated as inches *
72 (72 DPI), note the numeric values (612 and 792) and intended usage (PDF/page
sizing in points). Update the declarations for PAGE_WIDTH_PT and PAGE_HEIGHT_PT
to include those JSDoc comments above the export lines so they are consistent
with the existing constants.

In `@apps/web/src/env.ts`:
- Line 17: The NEXTAUTH_SECRET environment entry currently uses a hardcoded
default which is a security risk; remove the .default("super_long_secret") so
the zod schema requires the variable to be present (e.g., change NEXTAUTH_SECRET
to z.string().min(1).describe("NextAuth secret for signing tokens") or simply
z.string().describe(...) so missing secret throws during build), and update any
accompanying docs or .env.sample to instruct devs to set NEXTAUTH_SECRET rather
than relying on a fallback; modify the symbol NEXTAUTH_SECRET in
apps/web/src/env.ts accordingly.

In `@packages/database/package.json`:
- Around line 33-35: The package.json pins Prisma packages inconsistently:
"@prisma/client" uses a caret range "^7.4.0" while
"@prisma/client-runtime-utils" is exact "7.4.0", which can lead to runtime
mismatch; update the version specifiers so all Prisma packages use the same
format (either all caret ranges or all exact) — e.g., change
"@prisma/client-runtime-utils" to "^7.4.0" (or change the others to "7.4.0") and
ensure "@prisma/adapter-pg", "@prisma/client", and
"@prisma/client-runtime-utils" are kept in lockstep.

In
`@packages/database/prisma/migrations/20260214053852_add_user_account_models/migration.sql`:
- Around line 16-32: The accounts table lacks an index on the userId column
which hurts lookup performance; add an index for "accounts"."userId" (e.g.,
create index name accounts_userId_idx) by adding a CREATE INDEX
"accounts_userId_idx" ON "accounts"("userId"); statement to the migration so
lookups and cascade/delete queries against the accounts table use the index
instead of sequential scans.
- Around line 1-14: The users table migration creates a profileImageUrl column
that the later migration 20260214073452_update_image_field immediately drops;
instead squash these into a single migration so the initial CREATE TABLE uses
the correct column name "image" (replace "profileImageUrl" with "image" and its
type in the 20260214053852_add_user_account_models migration), remove the
redundant add/drop migration or merge its changes into the first migration, and
ensure any references to profileImageUrl in schema or code are updated to use
"image" so fresh DBs are created with the final schema.

In `@packages/database/prisma/models/user.prisma`:
- Around line 1-17: The User model currently allows email to be nullable (email:
String?) while password exists for credential auth, which lets credential users
be created without an email; to fix, decide on a single source of truth and
enforce it: if credential-based users must have an email, change the User
model's email field to non-nullable and unique (email: String `@unique`) in model
User, run a migration to backfill/clean existing rows, and update any sign-up
logic that creates users (e.g., credential signup handlers) to provide/validate
email; alternatively, if you need to keep nullable for OAuth-only users, add
application-level validation in the credential creation flow to reject or
require email before persisting a User (reference: User.email and
User.password).
- Around line 19-37: Add a DB index for Account.userId to speed lookups: inside
the Prisma model Account (model Account { ... }) add an index declaration like
@@index([userId]) so queries that search accounts by userId (e.g., sign-in
lookups) use the index; keep the existing @@unique([provider,
providerAccountId]) and @@map("accounts") intact.

In `@packages/database/prisma/schema.prisma`:
- Around line 7-11: Update the Prisma generator block in schema.prisma by
changing the provider value for the existing generator named "client" from
"prisma-client-js" to "prisma-client" so the generator block (generator client {
provider = "prisma-client" output = "../generated/prisma" engineType = "client"
}) uses the Prisma 7.x-compatible provider; locate the generator client block
and replace the provider string accordingly.

In `@packages/database/scripts/migrate-dev.sh`:
- Around line 1-3: Update the migrate-dev.sh script to harden input handling and
script failure behavior: add a safety header using set -euo pipefail at the top,
and change the read invocation in the line using read -p "Migration name: " name
to read -rp "Migration name: " name to prevent backslash interpretation; keep
the existing bun run with-env prisma migrate dev --schema ./prisma --name
"$(date +%Y%m%d_%H%M%S)_${name}" command unchanged.

In `@packages/database/tsup.config.ts`:
- Line 10: Update the external array in tsup.config.ts by removing the redundant
explicit entries "@prisma/client" and "@prisma/adapter-pg" (they are already
matched by the /^@prisma\// regex) while keeping ".prisma/client" and the regex
intact; modify the external: [...] line accordingly to reduce noise.

Next.js 15 remotePatterns new URL() shorthand glob patterns syntax

💡 Result:

images.remotePatternsnew URL() shorthand” (Next.js ≥ 15.3.0)

You can provide remotePatterns as an array of URL objects, where the URL string encodes the pattern:

// next.config.js
module.exports = {
  images: {
    remotePatterns: [new URL('https://example.com/account123/**')],
  },
}

This is equivalent to the object form (protocol/hostname/port/pathname/search). [1]

Glob / wildcard syntax (hostname + pathname)

Wildcard patterns work for hostname and pathname:

  • * = matches one subdomain (hostname) or one path segment (pathname)
  • ** = matches many subdomains only at the beginning of hostname, or many path segments only at the end of pathname
    (i.e. ** does not work in the middle of a pattern) [1]

Examples:

remotePatterns: [
  { protocol: 'https', hostname: '**.example.com' },  // subdomains
  { protocol: 'https', hostname: 'example.com', pathname: '/images/**' }, // paths
]

Query string (search) rules (important with new URL())

  • No globbing for search; it must match exactly if provided. [2]
  • If you use new URL(...) and don’t include ?…, the resulting pattern has search: '' (so query params are not allowed). [2]
  • To allow any query params, use the object form and omit the search key. [2]

Overly specific avatar remote pattern restricts image optimization to a single user; proposed fix omits query params required by GitHub avatars.

Line 14 restricts to /u/19688908?v=4 — only one GitHub user avatar will pass the pattern. Since the app uses GitHub OAuth with dynamic user avatars (stored in the database via profile.avatar_url), this will cause image optimization failures for all actual users.

The proposed fix (new URL("https://avatars.githubusercontent.com/**")) addresses the user ID issue but introduces a new problem: new URL() without a query string enforces search: '', which blocks query parameters. GitHub's avatar_url includes ?v=4 for cache-busting, so this pattern will fail on real OAuth avatars.

🔧 Proposed fix: use object form to allow any user ID and query params

In `@apps/web/next.config.ts` around lines 13 - 16, remotePatterns currently uses
new URL(...) which either hardcodes a single avatar path or disallows query
strings; replace those new URL(...) entries with object-form patterns so GitHub
avatar URLs with queries are allowed. Specifically, change the avatars entry to
an object like { protocol: "https", hostname: "avatars.githubusercontent.com",
pathname: "/u/**" } and change the raw GitHub entry to { protocol: "https",
hostname: "raw.githubusercontent.com", pathname: "/prebuiltui/**" } so dynamic
user IDs and query params (e.g. ?v=4) are accepted by Next.js image
optimization.

@auth/prisma-adapter version 2 Auth.js v5 compatibility

💡 Result:

@auth/prisma-adapter v2.x is the official Prisma adapter line intended for Auth.js / NextAuth.js v5 (the v5 migration guide explicitly says to switch from @next-auth/prisma-adapter to @auth/prisma-adapter). [1]

  • If you’re on NextAuth.js v5: use @auth/prisma-adapter@^2. [1][2]
  • If you’re on NextAuth.js v4: don’t use @auth/* adapters—use @next-auth/prisma-adapter instead (the @auth/* adapters are not type-compatible with v4). [3]

Note: there have been reported incompatibilities/bugs for some @auth/prisma-adapter 2.x versions with certain Prisma 6.x versions (example issue: @auth/prisma-adapter@2.9.0 with @prisma/client@6.6.0).

💡 Result:

next-auth v4 is compatible with Next.js 16, as long as you’re on a recent v4 patch.

  • Starting with next-auth 4.24.12 (and 4.24.13), the package’s peerDependencies explicitly allow next: ^12.2.5 || ^13 || ^14 || ^15 || ^16, so Next.js 16 installs cleanly without peer-dep conflicts. [1]
  • Next.js 16 is a released/stable major (released Oct 21, 2025). [2]

If you’re on an older next-auth v4 patch and seeing dependency issues, upgrade to next-auth@^4.24.13. If you want the newer Auth.js APIs, consider next-auth v5 (beta) instead (separate migration). [1]

Package mismatch: @auth/prisma-adapter v2.x is incompatible with next-auth v4.

@auth/prisma-adapter (v2.x) is the official adapter for Auth.js v5 only. For next-auth v4 (^4.24.13), the correct adapter is @next-auth/prisma-adapter. Using @auth/prisma-adapter with next-auth v4 causes type incompatibility and runtime failures because the adapter interfaces differ between v4 and v5.

Fix: Either use @next-auth/prisma-adapter if staying on next-auth v4, or upgrade to next-auth@^5.x (Auth.js) to match @auth/prisma-adapter@^2.11.1.

NextAuth v4 compatibility Next.js 15 16 breaking changes

💡 Result:

NextAuth v4 + Next.js 15/16: compatibility + what breaks

Next.js 15 (generally works with NextAuth v4, but watch for one major breaking change)

  • Breaking change: request-bound APIs became async: cookies(), headers(), draftMode(), plus params/searchParams in various places. Any auth/session code (yours or a dependency’s) that reads these synchronously can break. (nextjs.org)
  • If you’re on NextAuth v4, use the latest 4.24.x line (still the “stable” track). (releasealert.dev)

Next.js 16 (NextAuth v4 is not officially compatible)

  • Next.js 16 removes the temporary sync compatibility: those same request APIs must be awaited; sync access is fully removed. This is the big “it used to limp along in 15, now it hard-fails” change. (nextjs.org)
  • NextAuth v4 declares a peer dependency for next only up to ^15, so installing it in a Next.js 16 project triggers dependency resolution errors (unless you force/legacy-peer-deps it). (github.com)

What to do if you need Next.js 16

  • Migrate to Auth.js / NextAuth v5 (App Router-first, introduces the universal auth() API and updates server/middleware/route-handler patterns). (authjs.cn)
  • Or stay on Next.js 15 with NextAuth v4 (latest 4.24.x) until your auth stack officially supports 16. (releasealert.dev)

  • Auth.js / NextAuth.js v5 (next-auth v5 beta): the v5 migration docs state the minimum required Next.js version is 14.0, but they don’t yet explicitly claim/support Next.js 16, and users report the same peer-dependency install conflict on Next.js 16. [1], [2]
  • Latest published versions (per release trackers): next-auth 4.24.13 (stable) and 5.0.0-beta.30 (beta) were published in late Oct 2025. [3]

Practical implication for Next.js 16 (today): expect npm peer-dep conflicts with both v4 and v5 beta unless/until the project widens the next peer range; typical workarounds are --legacy-peer-deps / --force, or staying on Next.js 15. [1]

NextAuth v4 is incompatible with Next.js 16; requires immediate action.

NextAuth v4 declares peer dependency next@"^12.2.5 || ^13 || ^14 || ^15" and explicitly excludes Next.js 16. Next.js 16 removes the temporary sync compatibility layer for request APIs (cookies(), headers(), etc.), causing hard failures for any code accessing these synchronously.

While the current auth plugin architecture (forwarding cookies to the NextAuth session endpoint) is sound and avoids direct sync request API usage, it still depends on NextAuth v4 correctly handling Next.js 16's async APIs—which it is not designed for.

⚠️ Do not upgrade to next-auth@^5.x yet: Auth.js v5 is currently beta and also lacks official Next.js 16 support as of October 2025, creating the same peer-dependency conflicts.

Options:

  • Downgrade to Next.js 15 with current NextAuth v4 until Auth.js v5 officially supports Next.js 16
  • Monitor Auth.js v5 release timeline for stable Next.js 16 support
  • Investigate whether forcing the installation with workarounds is viable for your use case

⚠️ Potential issue | 🟠 Major

Email should be normalized in authorize to match signup normalization.

The authorize function looks up users by credentials.email without normalizing it. If the signup route normalizes emails (lowercased + trimmed), the login lookup must do the same, or users may fail to authenticate.

⚠️ Potential issue | 🟡 Minor

Consider whether email should be nullable for credential-based authentication.

Line 4: email is String? (optional), which is fine for pure OAuth users. However, the password field (Line 7) enables credential-based auth where email is typically the identifier. There's no application-level or database-level constraint preventing a credential user from being created without an email, which could lead to orphaned accounts that can't log in.

If credential auth requires email, consider enforcing this at the database or application layer.

🤖 Prompt for AI Agents
In `@packages/database/prisma/models/user.prisma` around lines 1 - 17, The User
model currently allows email to be nullable (email: String?) while password
exists for credential auth, which lets credential users be created without an
email; to fix, decide on a single source of truth and enforce it: if
credential-based users must have an email, change the User model's email field
to non-nullable and unique (email: String `@unique`) in model User, run a
migration to backfill/clean existing rows, and update any sign-up logic that
creates users (e.g., credential signup handlers) to provide/validate email;
alternatively, if you need to keep nullable for OAuth-only users, add
application-level validation in the credential creation flow to reject or
require email before persisting a User (reference: User.email and
User.password).

Add an index on Account.userId for query performance.

Session has @@index([userId]) but Account does not. Lookups by userId on the accounts table (e.g., "find accounts for this user" during sign-in) will require a sequential scan as the table grows.

🧩 Analysis chain

🌐 Web query:

Prisma 7 generator provider "prisma-client" vs "prisma-client-js"

💡 Result:

In Prisma ORM v7, these are two different Prisma Client generators:

  • provider = "prisma-client" (new / Prisma 7 default)

    • The new generator introduced in v6.6 and made default in v7.
    • Built for Prisma 7’s newer architecture (query compiler), works better with ESM/modern runtimes and bundlers, and is TypeScript-first. [1][2][3]
  • provider = "prisma-client-js" (legacy)

    • The old/default generator in Prisma 6.x and earlier.
    • It’s deprecated as of Prisma 7 and intended to be in maintenance mode. It’s the “classic” workflow that generates client code into node_modules (via the @prisma/client package behavior). [2][4]

Practical rule: for Prisma 7, prefer prisma-client unless you have a specific reason to stay on the legacy generator. [1][2][4]

Sources:
[1] Prisma ORM GitHub Releases (Prisma 7: make prisma-client default; switch providers)
[2] Prisma blog: “Why Prisma ORM Generates Code into Node Modules & Why It’ll Change” (new prisma-client vs prisma-client-js, v6.6 → v7)
[3] Prisma blog: “Prisma 7 Explained…” (difference between prisma-client-js and prisma-client)
[4] Prisma docs (Chinese mirror): prisma-client-js deprecated since Prisma 7, recommends prisma-client


Change generator provider to "prisma-client" for Prisma 7.x compliance.

The current provider "prisma-client-js" is the legacy generator deprecated in Prisma 7 and in maintenance mode only. Prisma 7.x requires "prisma-client" as the default generator—it was introduced in v6.6 and is now the modern, TypeScript-first standard with better ESM and bundler support. Update the provider immediately.

⚠️ Potential issue | 🟡 Minor

Thrown errors in signIn callback won't surface custom messages to users.

The throw new Error(...) at lines 259-261 is outside the try block, so it propagates to NextAuth. However, NextAuth's signIn callback doesn't forward thrown error messages to the client — it redirects to the default error page with a generic message. To surface the custom message, return a URL string with an error query parameter (e.g., return "/signin?error=NoEmail") instead of throwing.

Silent sign-in denial hides root cause from users.

Inconsistent optionality: GitHub OAuth is required but Google is optional.

NEXTAUTH_GITHUB_CLIENT_ID and NEXTAUTH_GITHUB_CLIENT_SECRET are required (z.string()), while the Google equivalents are .optional(). Yet the NextAuth route configures both providers unconditionally. If Google creds are intentionally optional, the route should conditionally include GoogleProvider. If both should always be present, make them both required here.

⚠️ Potential issue | 🔴 Critical

Heredoc lines contain leading whitespace that will corrupt .env.local keys.

The << EOF heredoc preserves all leading whitespace. Each line inside the heredoc is indented with spaces, so the resulting .env.local will contain entries like ⎵⎵⎵⎵⎵⎵DATABASE_URL=... instead of DATABASE_URL=.... The app won't recognise those keys.

Either strip the indentation from the heredoc body or use <<- with tab indentation (though that only strips tabs, not spaces).

Unsafe cast — account.access_token can be undefined for credentials sign-in.

account.access_token as string is an unsafe assertion. For the credentials provider, access_token is undefined, so this stores undefined disguised as string on the token. Use a safer fallback or guard.

⚠️ Potential issue | 🟠 Major

User + account creation is not wrapped in a transaction — possible orphan user on failure.

If prisma.user.create succeeds but prisma.account.create fails (e.g., unique constraint race, transient DB error), an orphan user record without an associated account is left behind. The next OAuth sign-in attempt would then hit the existingUser branch and try to upsert, which may work — but the user's state is inconsistent in the interim.

Wrap both operations in prisma.$transaction to ensure atomicity.

In `@apps/web/src/app/api/auth/`[...nextauth]/route.ts around lines 298 - 324, The
user and account creation must be made atomic: replace the separate
prisma.user.create and prisma.account.create calls with a single transactional
operation using prisma.$transaction so both inserts succeed or both roll back;
inside the transaction callback use a transaction client (tx.user.create and
tx.account.create) to create the user (previously newUser) and then the account
(previously using account data) and return the created user/account as needed,
ensuring any error aborts the whole transaction and no orphan user is left
behind.
