Setup for cross domains and local "cross ips" development?
Hey all! I have migrated my "supabase everything backend" to a hono+better-auth backend and I couldn't be happier! I have tried NextAuth/AuthJS and Lucia before but they all felt unreliable and poorly implemented. Better-auth as young as it is the best js auth solution I've ever used!
The only problem I'm having is with cross domain auth... I have 2 situations that are not working:
- Local development with cross ip: I run my backend and frontend on my computer and try to open my frontend on my phone through a local ip like "192.168.22.168:8081".
- I have deploy previews configured on cloudflare pages, so when I open a PR it creates a preview url like branch-name.my-app.pages.dev (this is a cloudflare subdomain not on my custom domain, so its a cross-domain)
On both situations I am able to make the sign in request (CORs is properly configured) but the session is not persisted (I think) so when I hit "/get-session" it returns NULL. Works fine when its the same domain (app.mydomain.com -> api.mydomain.com/auth) or when its localhost:xxxx -> localhost:yyyy
Any ideas on why this happens and how I can set this up?
