+title: Typescript
+description: Better auth typescript integration
+---
+
+Better Auth is designed to be type-safe. Both the client and server are built with TypeScript, allowing you to easily infer types.
+
+## Infering Types
+
+Both the client SDK and the server offer types that can be inferred using the `$Infer` property. Plugins can extend base types like `User` and `Session`, and you can use `$Infer` to infer these types. Additionally, plugins can provide extra types that can also be inferred through `$Infer`.
+
+```ts title="client.ts" twoslash
+import { createAuthClient } from "better-auth/client"
+
+const client = createAuthClient()
+
+export type Session = typeof client.$Infer.Session
+```
+
+The `Session` type includes both `session` and `user` properties. The user property represents the user object type, and the `session` property represents the `session` object type.
+
+You can also infer types on the server side.
+
+```ts title="auth.ts" twoslash
+import { betterAuth } from "better-auth"
+
+export const auth = await betterAuth({
+    database: {
+        provider: "sqlite",
+        url: "./db.sqlite",
+    }
+})
+
+type Session = typeof auth.$Infer.Session
+```
