Inferred type of betterAuth client exceed compiler serialization

Hi, Im getting this typescript error in my project. Any suggestion on how to solve it? `The inferred type of this node exceeds the maximum length the compiler will serialize. An explicit type annotation is needed.``

have you enabled strict in tsconfig? @discquist https://www.better-auth.com/docs/concepts/typescript#strict-mode
TypeScript | Better Auth
Better Auth TypeScript integration.

Normally this solves it. Can I see your entire tsconfig?

for me it's

  "display": "Next.js",
  "extends": "./base.json",
  "compilerOptions": {
    "strict": true,

    "module": "ESNext",
    "moduleResolution": "Bundler",
    "allowJs": true,
    "jsx": "preserve",
    "noEmit": true
  }
}

Check if you disable declaration if it will work

Hello, @discquist , could you try disabling declaration as well?
discquist
discquistOP•6d ago
Yeah i'll try that.But unsure if i want to do that since i use a ackend framework (encore.ts) that allows me to generate fully typed client to consume in my frontend. @Ping Yeah, not possilbe for me to disbale declaration in my projet. So i htink one solution would be if i can set the type of the instance or something?

You can set it to ReturnType<typeof betterAuth>, but you won't get any inference for any plugins or other configurations you may have added.
