Is this suited for github?

  • Yes, this is suited for github

To Reproduce

BACKGROUND
Implemented passkey flow based on passkey plugin semantics.
Route for auth worked for session via OTP and email, didn't work for passkeys.

`app/api/auth/[...all]/route.ts

"use server-only";

import auth from "~/server/auth/config";
import { toNextJsHandler } from "better-auth/next-js";

export const { GET, POST } = toNextJsHandler(auth.handler);
`

Currently attempting tRPC and using simplewebauthn methods directly.

`
import {
generateRegistrationOptions,
verifyRegistrationResponse,
generateAuthenticationOptions,
verifyAuthenticationResponse,
} from "@simplewebauthn/server";

A. Build errors experienced with either i) passkey plugin semantics or ii) simplewebauthn calls:
`
...

./src/server/auth/config.ts
./src/app/api/auth/[...all]/route.ts

Build failed because of webpack errors
`
B. Config changes suggested:

  1. Version Alignment: Installed the exact same versions that better-auth uses:
  • @simplewebauthn/server@13.2.1
  • @simplewebauthn/browser@13.2.0
  1. Package.json Resolutions:
    Added resolutions to force versions:
"resolutions": {
     "@simplewebauthn/server": "13.2.1",
     "@simplewebauthn/browser": "13.2.0"
   }
`
3. Webpack Externals in next.config.ts: 
  Added webpack configuration to prevent bundling conflicts:
`
webpack: (config, { isServer }) => {
    ...
    
    // Prevent better-auth from bundling its own @simplewebauthn packages
    if (isServer) {
      config.externals = config.externals || [];
      config.externals.push({
        '@simplewebauthn/server': 'commonjs @simplewebauthn/server',
        '@simplewebauthn/browser': 'commonjs @simplewebauthn/browser',
      });
    }
    
    return config;
  },
`

Simplewebauthn errors removed from build log now.

This information may help with some changes to the referencing of simplewebauthn in better-auth/plugin/passkey.

### Current vs. Expected behavior

simplewebauthn package rolled into better-auth was unable to correctly identify import helper functions. Caused conflict and subsequent build failures.

export { SECURITY_CONFIG };
export type Auth = typeof auth;
export default auth;

Additional context

Installed various versions of better-auth and the same helper import errors occurred. Appears to be the packaging of simplewebauthn within better-auth is missing something.

Everything in better-auth package seems to checkout, so excluding simplewebauthn there and forcing use of simplewebauthn directly, fixed it for me atm. A curly one indeed... good luck :)

Used 13.0.0.0 for simplwebauthn doc compatibility and various other versions eg. 13.1.2 , 13.2.1 etc.. Same results.

I'll admit I use packages and am unfamiliar with building them.

Compiler errors show better-auth packsge is expecting ./<helper_function>.js shouldn't it be <better-auth_package_root>/@simplewebauthn/server/esm/<helper> /<helper_function>.js

Focusing on a single version and ignoring the whole information base of the issue might explain why the are ~5000 issues.

I can move on with these config changes and use better-auth session an simplewebathn passkey semantics.

You can close this issue if you like. I'm good

This issue seems invalid. Please check the lockfile and node_modules to see what exactly version you are using

I think we're not gonna support the legacy version. And in the next year, maybe make ESM only
