In the age of fast-paced development and agile methodologies, Elide stands out as a powerful Java library aimed at simplifying the creation of APIs for web and mobile applications. This blog will walk you through how to set up Elide, utilize its features, and help you troubleshoot potential issues along the way.

Background
Elide is a Java library that allows developers to set up model-driven GraphQL or JSON API web services with minimal effort. Think of it as the architect of your API world, helping you build structures efficiently and effectively. With Elide, complex interactions can be simplified into straightforward CRUD operations and analytic queries.
Usage
To make the best out of Elide, here’s a simple analogy: imagine you’re building a library. Each book represents a data model, and Elide helps you manage that library effortlessly.
For CRUD operations, first, define your library’s structure:
java
@Entity
public class Book {
@Id
private Integer id;
private String title;
@ManyToMany(mappedBy = "books")
private Set authors;
}
Now, let’s add some magic with Elide annotations, allowing you to manage permissions for who can read, create, update, or delete books:
java
@Entity
@Include(rootLevel = true)
@ReadPermission(Everyone)
@CreatePermission(Admin OR Publisher)
@DeletePermission(None)
@UpdatePermission(None)
public class Book {
@Id
private Integer id;
@UpdatePermission(Admin OR Publisher)
private String title;
@ManyToMany(mappedBy = "books")
private Set authors;
}
But what if you want to trigger some events each time a book is updated, like sending a notification? This is where life cycle hooks come into play:
java
@LifeCycleHookBinding(operation = UPDATE, hook = BookCreationHook.class, phase = PRECOMMIT)
public class Book {
// Code remains the same...
}
public class BookCreationHook implements LifeCycleHook {
@Override
public void execute(LifeCycleHookBinding.Operation operation,
LifeCycleHookBinding.TransactionPhase phase,
Book book,
RequestScope requestScope,
Optional changes) {
// Trigger an event!
}
}
Security
Security is paramount when developing APIs, and Elide comes with built-in mechanisms to handle that. Check out their extensive security documentation here. It’s like having a reliable security team ensuring that only the right people have access to specific books in your library.
Documentation & Installation
Further instructions on utilizing Elide can be found on the official website at elide.io. To try out Elide in action, you can set up an example service using the elide-spring-boot-example or quickly run a local instance with the elide-standalone-example.
Troubleshooting
If you run into issues while setting up or using Elide, here are some troubleshooting tips:
- Ensure your IDE and dependencies are properly set up, including required plugins like Lombok.
- Check your annotations; incorrect permissions can lead to unexpected errors.
- Look into security settings if data access or manipulation fails.
