Is this suited for github?

  • Yes, this is suited for github

To Reproduce

  • My project uses the tanstack start plugin reactStartCookies is passed as the last plugin
  • The cookie is only secure if I explicitly pass useSecureCookies as true in the advanced config
  • The docs suggest that this should be done by default in such a setting (HTTPS domain with a production environment NODE_ENV)

Current vs. Expected behavior

Expected cookies to be secure without by default

What version of Better Auth are you using?

1.2.8

Provide environment information

Linux server, tanstack start

Which area(s) are affected? (Select all that apply)

  }
});

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

According to the docs, cookies should be secure by default when running in production mode—you only need to set useSecureCookies if you want to override this behavior or force it in development. The reactStartCookies plugin uses environment detection (typically NODE_ENV) to decide if cookies should be secure. If you're seeing insecure cookies in production, double-check that your environment is actually being detected as "production" (for example, NODE_ENV is set to "production" at runtime). If NODE_ENV or a similar variable isn't set as expected, the plugin may not enable secure cookies automatically, which matches what you're seeing. You can find more details in the docs and related discussions:

If you want to guarantee secure cookies regardless of environment detection, explicitly set useSecureCookies: true in your config.

To reply, just mention @dosu.

Ok I figured it out. I was not setting BETTER_AUTH_URL, and it infers the context from there (I assume it would do so from the request context). So setting the variable or passing baseUrl as a parameter would do.

While the documentation is generally very good, this would be a good improvement point :)
