Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  1. Install better auth in a nextjs 16 project
  2. Set up better auth configuration
  3. Use better auth in server components (e.g: auth pages)
  4. Build with bun runtime:
   bun --bun next build
  1. Build fails with chunk resolution error

Current vs. Expected behavior

Current behavior:

[MDX] generated files in 15.07799ms
   ▲ Next.js 16.0.10 (Turbopack, Cache Components)
   - Environments: .env

Error: Failed to collect page data for /organization/new
    at processTicksAndRejections (null) {
  type: 'Error'
}
error: "next" exited with code 1
error: script "build" exited with code 1

Expected behavior:
better auth should build successfully with bun runtime, similar to how it works with node.

What version of Better Auth are you using?

1.4.6

Additional context

However, adding better auth as serverExternalPackages works.

Originally created by @AmariUwU on GitHub (Dec 15, 2025). Originally assigned to: @himself65 on GitHub. ### Is this suited for github? - [x] Yes, this is suited for github ### To Reproduce 1. Install better auth in a nextjs 16 project 2. Set up better auth configuration 3. Use better auth in server components (e.g: auth pages) 4. Build with bun runtime: ```bash bun --bun next build ``` 5. Build fails with chunk resolution error ### Current vs. Expected behavior Current behavior: ``` [MDX] generated files in 15.07799ms ▲ Next.js 16.0.10 (Turbopack, Cache Components) - Environments: .env Creating an optimized production build ... ✓ Compiled successfully in 45s ✓ Finished TypeScript in 35.1s Collecting page data using 2 workers ...Error: Failed to load chunk server/chunks/ssr/bb1a9_better-auth_dist_adapters_kysely-adapter_dialect_mjs_7c6a251c._.js from runtime for chunk server/app/(main)/organization/new/page.js at loadRuntimeChunkPath (.next/server/chunks/ssr/[turbopack]_runtime.js:636:19) at loadRuntimeChunk (.next/server/chunks/ssr/[turbopack]_runtime.js:605:9) at c (.next/server/chunks/ssr/[turbopack]_runtime.js:766:25) at <anonymous> (.next/server/app/(main)/organization/new/page.js:21:3) at anonymous (null) at processTicksAndRejections (null) { [cause]: ResolveMessage {} } > Build error occurred Error: Failed to collect page data for /organization/new at processTicksAndRejections (null) { type: 'Error' } error: "next" exited with code 1 error: script "build" exited with code 1 ``` Expected behavior: better auth should build successfully with bun runtime, similar to how it works with node. ### What version of Better Auth are you using? 1.4.6 ### System info ```bash { "system": { "platform": "linux", "arch": "x64", "version": "#1 SMP PREEMPT_DYNAMIC Thu Jun 5 18:30:46 UTC 2025", "release": "6.6.87.2-microsoft-standard-WSL2", "cpuCount": 3, "cpuModel": "Intel(R) Core(TM) i5-10210U CPU @ 1.60GHz", "totalMemory": "7.64 GB", "freeMemory": "4.39 GB" }, "node": { "version": "v24.2.0", "env": "production" }, "packageManager": { "name": "bun", "version": "1.3.5" }, "frameworks": [ { "name": "next", "version": "16.0.10" }, { "name": "react", "version": "^19.2.3" } ], "databases": [ { "name": "pg", "version": "^8.16.3" }, { "name": "drizzle", "version": "^0.45.1" } ], "betterAuth": { "version": "^1.4.6", "config": { "baseURL": "http://localhost:4321", "basePath": "/api/auth", "experimental": { "joins": true }, "appName": "Ecom", "telemetry": { "enabled": false }, "disabledPaths": [ "" ], "session": { "freshAge": 300, "expiresIn": 604800, "cookieCache": { "enabled": true, "maxAge": 900 }, "storeSessionInDatabase": true }, "rateLimit": { "enabled": true }, "advanced": { "ipAddress": { "ipAddressHeaders": [ "cf-connecting-ip", "x-forwarded-for" ] }, "crossSubDomainCookies": { "enabled": true, "domain": "localhost" }, "cookiePrefix": "domain", "useSecureCookies": true }, "trustedOrigins": [ "http://localhost:4321", "http://localhost:3000" ], "user": { "changeEmail": { "enabled": true, "updateEmailWithoutVerification": false } }, "emailAndPassword": { "enabled": true, "autoSignIn": true, "revokeSessionsOnPasswordReset": true, "maxPasswordLength": 64, "minPasswordLength": 8, "requireEmailVerification": true, "resetPasswordTokenExpiresIn": 1800, "password": {} }, "emailVerification": { "autoSignInAfterVerification": true, "sendOnSignIn": true, "sendOnSignUp": true, "expiresIn": 1800 }, "account": { "accountLinking": { "enabled": true } }, "socialProviders": { "google": { "clientId": "[REDACTED]", "clientSecret": "[REDACTED]" }, "microsoft": { "clientId": "[REDACTED]", "clientSecret": "[REDACTED]" } }, "secondaryStorage": {}, "databaseHooks": { "session": { "create": {} } }, "plugins": [ { "name": "last-login-method", "config": { "id": "last-login-method", "hooks": { "after": [ {} ] }, "schema": { "user": { "fields": { "lastLoginMethod": { "type": "string", "input": false, "required": false, "fieldName": "lastLoginMethod" } } } } } }, { "name": "admin", "config": { "id": "admin", "hooks": { "after": [ {} ] }, "endpoints": {}, "$ERROR_CODES": { "FAILED_TO_CREATE_USER": "Failed to create user", "USER_ALREADY_EXISTS": "User already exists.", "USER_ALREADY_EXISTS_USE_ANOTHER_EMAIL": "User already exists.

Hi @AmariUwU! I'm Dosu and I’m helping the better-auth team.

This build failure happens because Better Auth's Kysely adapter uses dynamic imports and Node.js-specific modules (like node:sqlite) that Bun and Turbopack can't resolve or bundle properly in Next.js 16. The chunk resolution error is triggered when the bundler tries to process these Node-only modules, which aren't available or supported in the Bun runtime or Turbopack's chunking context see details.

Adding Better Auth as serverExternalPackages works because it tells the bundler to treat it as an external dependency, so it doesn't try to bundle or resolve those problematic imports reference. This is currently the recommended workaround for Bun + Next.js 16.

If you run into similar issues, make sure:

  • You only import Better Auth server code in server components (never in client components).
  • You use granular imports (not just import { ... } from "better-auth" everywhere).
  • You keep your Better Auth and Next.js versions up to date, as compatibility is still evolving reference.

Right now, marking Better Auth as serverExternalPackages is the best way to avoid these build errors with Bun and Next.js 16.

To reply, just mention @dosu.
