When hiring GraphQL developers, consider the following key technical skills:
Proficiency in GraphQL: Look for developers who have a deep understanding of GraphQL concepts, query language, and best practices.
Backend Technologies: Ensure that the developers are experienced with relevant backend technologies such as Node.js, Express.js, or other frameworks commonly used in GraphQL implementations.
Database Knowledge: Assess their proficiency in working with databases like MongoDB, PostgreSQL, or MySQL, as GraphQL often interacts with these data sources.
API Design and Integration: Look for developers who have experience in designing and integrating APIs using GraphQL. They should be familiar with schema design, resolvers, mutations, and subscriptions.
Testing and Debugging: Consider developers who have a good grasp of API testing and debugging common issues that may arise during development.
GraphQL differs from REST APIs in several ways. First, with GraphQL, you can request exactly the data you need and receive it in a single request, reducing unnecessary data transfers. In contrast, REST APIs often return fixed data structures, requiring multiple requests to fetch related data. Second, GraphQL provides a strongly-typed schema, allowing you to define the data structure and relationships upfront. In contrast, REST APIs rely on documentation and conventions. Third, GraphQL enables clients to specify their data requirements, resulting in fewer round trips to the server. REST APIs typically have pre-defined endpoints, limiting flexibility. Overall, GraphQL offers a more efficient and flexible approach to data fetching compared to REST APIs.
GraphQL is suitable for a wide range of projects. Its flexibility makes it ideal for applications with complex and evolving data requirements. If you anticipate frequent changes in your data structure or have varying client needs, GraphQL can simplify the development process. Additionally, if you require efficient data fetching, real-time updates, or have a diverse set of clients (web, mobile, IoT), GraphQL can handle these scenarios effectively. However, if your project has a simple data structure and predictable client needs, REST APIs might suffice. Assess your project's specific requirements and consult with a GraphQL expert to determine if it is the right fit.
In the last article we added a few GraphQL mutations to our test application. It is time to create automated tests for each of them. But first things first, we need to set up `RSpec` in order to write better specs.

Today we are going to add specs (again, we will focus only on the happy paths) for GraphQL queries. But there is one thing about the current implementation of the queries that I don’t like. We have everything defined in one file: `app/graphql/types/query_type.rb`
Invalid Date
In this article, I would like to focus on adding GraphQL mutations. We will be working on the test application we created previously in this article. It might be helpful for you to know the structure, models, and types we are using so I encourage you to take a look.
