Create user with custom ID

Is there a way to pass it the id I want from the outside? It doesn't seem to have any parameter that would allow me to do that 😦

Infer type before initializing betterAuth

I think I got it. Here's the diff of the changes I did

   }

The interesting part would be this

const plugins = [anonymous, jwt];

type Plugins = typeof plugins;
type PlugInReturnTypes = ReturnType<Plugins[number]>;
type PluginEndpoints = UnionToIntersection<PlugInReturnTypes['endpoints']>;
type PluginApis = {
  api: PluginEndpoints;
};

const plugins = [anonymous, jwt];

type Plugins = typeof plugins;
type PlugInReturnTypes = ReturnType<Plugins[number]>;
type PluginEndpoints = UnionToIntersection<PlugInReturnTypes['endpoints']>;
type PluginApis = {
  api: PluginEndpoints;
};

Have fun 😉
