+In TypeScript, it would look like this:
+
+```typescript
+import Joi, { SchemaMap } from '@hapi/joi';
+import validate from 'express-joi-validate';
+
+const contactSchema: SchemaMap = {
+  params: {
+    id: Joi.number().required()
+  }
+};
+
+app.get('/contacts/:id', validate(contactSchema), contactsHandler);
+```

+Note: for the above, the type `SchemaMap` is inferred and not required.
