+### Typescript
+
+If we are working on a Typescript project, we can infer the types of the fields, so we have intellisense.
+
+#### Directly in Model
+```ts{}[~/models/User.ts]
+import Model from './Model'
+
+export default class User extends Model {
+ firstName: string
+ lastName: string
+ age: number
+
+ ...
+}
+```
+
+#### Using an Interface
+```ts{}[~/models/User.ts]
+import Model from './Model'
+
+interface User {
+ firstName: string
+ lastName: string
+ age: number
+}
+
+class User extends Model {
+ ...
+}
+
+export default User
+```
