Pass an instance provider rather than the better auth instance.

[xKrvZ]

I'm currently working on a project where the better auth instance can change on the fly. I'd like the ability to be able to pass in a better-auth instance provider instead of the better-auth instance itself. I've looked at the code and I've pulled it into my personal repo and modified it to work this way, it did take some doing but I got it to work in the end.

Hooks were fine to keep as they are since they are application level code anyway, but it's the plugins and config variables I wanted to change on the fly.

For reference, I added the ability to provide a method for returning a better auth instance here and modified some of the code elsewhere to handle this change.

Can you give an example of how that would look like? Like, changing it per request or something? Maybe https://docs.nestjs.com/recipes/async-local-storage is useful to you?

AsyncLocalStorage doesn’t help me. The result is being able to change the auth instance on the fly, check here

https://github.com/KieronWiltshire/ManagedBetter/blob/master/backend/src/modules/betterauth/services/betterauth.service.ts

This allows me to configure OAuth providers from an admin panel, enable/disable plugins on the fly, etc… the idea behind that repo is to create a completely managed better auth service you can run as a standalone docker container and that way your services don’t need to hard depend on your identity service.
