The inferred type of 'authClient' cannot be named without a reference...

Daniel · 2025-07-31T16:36:46.756Z

I was trying to create a shared auth client package in my monorepo, since I have multiple frontends authenticating with the same server.. But I keep getting an error like this (twice) even before adding any plugins... Literally.. this is my entire code: ``` import { createAuthClient } from "better-auth/client"; export const authClient = (baseURL: string) => { return createAuthClient({ baseURL, }); }; ``` I can't disable declaration in my tsconfig, since it's a shared package in my monorepo, and I need the type safety. I can't add an explicit return type like ReturnType since that ruins type safety for any plugins I might add.. Is this a bug in better-auth? Or did I get something wrong with the configuration

I'm getting this error twice:
The inferred type of 'authClient' cannot be named without a reference to '../node_modules/better-auth/dist/shared/better-auth.ClXlabtY.js'. This is likely not portable. A type annotation is necessary.ts(2742)

The inferred type of 'authClient' cannot be named without a reference to '../node_modules/better-auth/dist/shared/better-auth.ZSfSbnQT.js'. This is likely not portable. A type annotation is necessary.ts(2742)

There seems to be a few issues open about this from March, but they're marked as solved, which is really confusing..

I really want to work with better-auth on this project. But this is like the third typescript-related issue I ran into and it's really giving me a headache. Maybe I'm just doing something wrong.

I had similar issues, worked around this by doing things like this:

export const BETTER_AUTH_DEFAULT_SESSION = {

        ipAddress: BETTER_AUTH_FIELD.IP_ADDRESS,
        userAgent: BETTER_AUTH_FIELD.USER_AGENT,
        createdAt: BETTER_AUTH_FIELD.CREATED_AT,
        updatedAt: BETTER_AUTH_FIELD.UPDATED_AT,

You just have to break the config down into smaller parts, only the keys would not be type safe but I found that to be fine

And for the plugins, I did

export const baseDefaultUsernamePlugin = Object.freeze({
    schema: {
        user: {
            modelName: BETTER_AUTH_TABLE.AUTH_USERS,
            fields: { displayUsername: BETTER_AUTH_FIELD.DISPLAY_USERNAME },
        },
    },
    minUsernameLength: USERNAME_MIN_LENGTH,
    maxUsernameLength: USERNAME_MAX_LENGTH,
} satisfies Parameters<typeof username>[0]);

export const baseDefaultUsernamePlugin = Object.freeze({
    schema: {
        user: {
            modelName: BETTER_AUTH_TABLE.AUTH_USERS,
            fields: { displayUsername: BETTER_AUTH_FIELD.DISPLAY_USERNAME },
        },
    },
    minUsernameLength: USERNAME_MIN_LENGTH,
    maxUsernameLength: USERNAME_MAX_LENGTH,
} satisfies Parameters<typeof username>[0]);

export const baseDefaultUsernamePlugin = Object.freeze({
    schema: {

        },
    },
    minUsernameLength: USERNAME_MIN_LENGTH,
    maxUsernameLength: USERNAME_MAX_LENGTH,
} satisfies Parameters<typeof username>[0]);

export const baseDefaultUsernamePlugin = Object.freeze({

Spread your configs into your betterAuth function in each app that uses it, and you should have decent enough type safety there

D

DanielOP•7/31/25, 5:06 PM

This just seems like terrible developer experience

DDN_Dev And for the plugins, I did ``` export const baseDefaultUsernamePlugin = Object....

D

DanielOP•7/31/25, 5:11 PM

I'm not sure if I fully understand yet.. but I did something like:

import { createAuthClient } from "better-auth/client";
import { adminClient } from "better-auth/client/plugins";

const defaultConfig = {
  baseURL: "http://localhost:3000",
  plugins: [adminClient()],
} satisfies Parameters<typeof createAuthClient>[0];

export const authClient = (
  baseURL: string
): ReturnType<typeof createAuthClient<typeof defaultConfig>> => {
  return createAuthClient({
    ...defaultConfig,
    baseURL,
  });
};

import { createAuthClient } from "better-auth/client";
import { adminClient } from "better-auth/client/plugins";

const defaultConfig = {
  baseURL: "http://localhost:3000",
  plugins: [adminClient()],
} satisfies Parameters<typeof createAuthClient>[0];

export const authClient = (
  baseURL: string
): ReturnType<typeof createAuthClient<typeof defaultConfig>> => {
  return createAuthClient({
    ...defaultConfig,
    baseURL,
  });
};

import { createAuthClient } from "better-auth/client";
import { adminClient } from "better-auth/client/plugins";

const defaultConfig = {
  baseURL: "http://localhost:3000",
  plugins: [adminClient()],
} satisfies Parameters<typeof createAuthClient>[0];

export const authClient = (
  baseURL: string
): ReturnType<typeof createAuthClient<typeof defaultConfig>> => {
  return createAuthClient({
    ...defaultConfig,
    baseURL,
  });
};

import { createAuthClient } from "better-auth/client";
import { adminClient } from "better-auth/client/plugins";

const defaultConfig = {
  baseURL: "http://localhost:3000",
  plugins: [adminClient()],
} satisfies Parameters<typeof createAuthClient>[0];

export const authClient = (
  baseURL: string
): ReturnType<typeof createAuthClient<typeof defaultConfig>> => {
  return createAuthClient({
    ...defaultConfig,
    baseURL,
  });
};

for example, and the error still appears, just now for defaultConfig instead of authClient

DanielOP•7/31/25, 5:11 PM

The inferred type of 'defaultConfig' cannot be named without a reference to '../node_modules/better-auth/dist/shared/better-auth.2lcgvW_O.js'. This is likely not portable. A type annotation is necessary.ts(2742)

Yeah it's not great when it comes to this. If you spread the entire objects you'll get these issues unfortunately. Instead of

satisfies Parameters<typeof createAuthClient>[0]

satisfies Parameters<typeof createAuthClient>[0]

satisfies Parameters<typeof createAuthClient>[0]

satisfies Parameters<typeof createAuthClient>[0] you should use

as const

as const

as const

as const and type each key if you need to instead e.g.

type AuthClient = Parameters<typeof createAuthClient>[0]
const defaultConfig = {
  baseURL: "http://localhost:3000" satisfies AuthClient["baseURL"],
  plugins: [adminClient()] satisfies AuthClient["plugins"],
} as const

type AuthClient = Parameters<typeof createAuthClient>[0]
const defaultConfig = {
  baseURL: "http://localhost:3000" satisfies AuthClient["baseURL"],
  plugins: [adminClient()] satisfies AuthClient["plugins"],
} as const

type AuthClient = Parameters<typeof createAuthClient>[0]
const defaultConfig = {
  baseURL: "http://localhost:3000" satisfies AuthClient["baseURL"],
  plugins: [adminClient()] satisfies AuthClient["plugins"],
} as const

type AuthClient = Parameters<typeof createAuthClient>[0]
const defaultConfig = {
  baseURL: "http://localhost:3000" satisfies AuthClient["baseURL"],
  plugins: [adminClient()] satisfies AuthClient["plugins"],
} as const

Something like that...unfortunately that means you lose auto suggestion for config keys but I found that to be manageable. Each key can be copied from the indexed access type i.e. AuthClient["copy-this-here"]

DDN_Dev Yeah it's not great when it comes to this. If you spread the entire objects you'...

D

DanielOP•7/31/25, 5:41 PM

I did this, and I still don't get type safety for authClient.admin for example.. Is that what you meant?
Cause then I could just set the return type explicitly to ReturnType<typeof createAuthClient>

D

DN_Dev•7/31/25, 5:48 PM

Sorry, typing plugins explicitly like that would mean you lose type safety there. Here's an e.g. of my plugins array which is passed to my betterAuth instance.

const plugins = [
    twoFactor({

    emailOTP({

        }),
    }),
    admin({ ...baseDefaultAdminPlugin }),
    organization({ ...baseDefaultOrganizationPlugin }),
];

const plugins = [
    twoFactor({
        ...baseDefaultTwoFactorPlugin,
    }),
    username({
        ...baseDefaultUsernamePlugin,
        usernameValidator: getUsernameValidator(),
    }),

    }),

Above is what you would need to do in each app that uses plugins. I export the default configs from the auth package in my monorepo.

E.g.

export const baseDefaultAdminPlugin = Object.freeze({

            modelName: BETTER_AUTH_TABLE.AUTH_ADMINS,
            fields: {

                banExpires: BETTER_AUTH_FIELD.BAN_EXPIRES_AT,
            },
        },
        session: {
            modelName: BETTER_AUTH_TABLE.AUTH_SESSIONS,
            fields: { impersonatedBy: BETTER_AUTH_FIELD.IMPERSONATED_BY },
        },
    },
} satisfies Parameters<typeof admin>[0]);

export const baseDefaultAdminPlugin = Object.freeze({
    schema: {
        user: {
            modelName: BETTER_AUTH_TABLE.AUTH_ADMINS,
            fields: {
                banned: BETTER_AUTH_FIELD.IS_BANNED,
                banReason: BETTER_AUTH_FIELD.BAN_REASON,
                banExpires: BETTER_AUTH_FIELD.BAN_EXPIRES_AT,
            },
        },
        session: {
            modelName: BETTER_AUTH_TABLE.AUTH_SESSIONS,
            fields: { impersonatedBy: BETTER_AUTH_FIELD.IMPERSONATED_BY },
        },
    },
} satisfies Parameters<typeof admin>[0]);

export const baseDefaultAdminPlugin = Object.freeze({

man. at this point I might as well just create the client in each app separately and just disable declaration in my tsconfig, since they don't export anything anyway.

@bekacru any chance this will be addressed in a future update? it really sucks to have to either lose my one source of truth, or have to know how to do awesome typescript backflips like @DN_Dev

DDaniel man. at this point I might as well just create the client in each app separately...

Yeah that's basically what I had to do, and export as much code as I could to each auth instance in the apps

i only had an issue with jwt and passkey plugin

i was able to fix it by explicitly typing those to just be a BetterAuthPlugin

this would break the ts inference. can you share with me your auth client config when you can

jwt breaks due to jose, passkey due to some webauthn library

this setup right now works for me because the clients infer from their plugins and not from the server

sneakyf1shy•9/14/25, 8:22 PM

also i did move this to a seperate package and have it compiled, cause i was getting errors like 'stripeCustomerId' doesnt exist on user due to the type inference depth/complexity.

compiling/composite helped quite a bit

what's in your tsconfig? May I see it?

like the TS server being slow, or not being able to infer at depth which would lead to stuff like 'stripeCustomerId does not exist on type User'
