Hilla integrates a Spring Boot Java backend with a reactive TypeScript front end. It helps you build apps faster with type-safe server communication, included UI components, and integrated tooling.
## Simple type-safe server communication
Hilla helps you access the backend easily with type-safe endpoints.
`index.ts`
```ts
// Type info is automatically generated based on Java
import Person from 'Frontend/generated/com/vaadin/hilla/demo/entity/Person';
import { PersonEndpoint } from 'Frontend/generated/endpoints';
async function getPeopleWithPhoneNumber() {
const people: Person[] = await PersonEndpoint.findAll();
// Compile error: The property is 'phone', not 'phoneNumber'
return people.filter((person) => !!person.phoneNumber);
}
console.log('People with phone numbers: ', getPeopleWithPhoneNumber());
```
`PersonEndpoint.java`
```java
@Endpoint
@AnonymousAllowed
public class PersonEndpoint {
private PersonRepository repository;
public PersonEndpoint(PersonRepository repository) {
this.repository = repository;
}
public @Nonnull List<@Nonnull Person> findAll() {
return repository.findAll();
}
}
```
`Person.java`
```java
@Entity
public class Person {
@Id
@GeneratedValue
private Integer id;
@Nonnull private String firstName;
@Nonnull private String lastName;
@Email @Nonnull private String email;
@Nonnull private String phone;
// getters, setters
}
```
