Is this suited for github?

  • Yes, this is suited for github

To Reproduce

Follow the instructions to add the new better-auth/infra package to a project using tanstack start and deploy on Netlify

Current vs. Expected behavior

After following the directions to add the new @better-auth/infra package and deploying a tanstack start application to Netlify, I get the following error when trying to load the site:

Error - require() of ES Module /var/task/node_modules/camelcase/index.js from /var/task/node_modules/samlify/build/src/extractor.js not supported. Instead change the require of index.js in /var/task/node_modules/samlify/build/src/extractor.js to a dynamic import() which is available in all CommonJS modules.

Stack Trace

Error [ERR_REQUIRE_ESM]: require() of ES Module /var/task/node_modules/camelcase/index.js from /var/task/node_modules/samlify/build/src/extractor.js not supported.
Instead change the require of index.js in /var/task/node_modules/samlify/build/src/extractor.js to a dynamic import() which is available in all CommonJS modules.

Additional context

Better Auth works just fine without adding the new package.

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

This is a known issue with the @better-auth/infra package. The package has a critical CommonJS compatibility bug due to its package.json exports using the "import" condition instead of "default", which breaks serverless deployments like Netlify.

The maintainers acknowledged this issue on March 5, 2026 and are investigating. Unfortunately, there's no consumer-side workaround for this package-level issue at the moment.

In the meantime:

  • If you only need SAML/SSO functionality (not the dashboard), you may be able to use @better-auth/sso directly instead
  • Monitor issues #8332 and #8414 for updates on the fix
  • Ensure your project has "type": "module" in package.json (though this won't fully resolve the infra package issue)

To reply, just mention @dosu.

Here's a temp workaround until upstream fixes the bug. In your package.json add:

+  "resolutions": {
+    "samlify/camelcase": "6.3.0"
+  },

This instructs npm/yarn to use an older version of camelcase, which was still published with CJS support. This allows samlify to consume it with require.

Hey @SleeveShirtholes @nkrkv , not too familiar with Netlify, but any chance are you trying to deploy to a target that does not support require(esm)?

Please note that we currently require your target environment to support that, for Node.js specifically that means:

Node 20 20.19.0
Node 22 22.12.0

I deploy to Vercel with Node 24. They probably don't support requiring ESM, but users don't have control over it anyway.
