Why GraphQL is the future of API development: Essential tips and tools for developers

Watch this video for key points discussed about GraphQL, its benefits, challenges, and practical advice for developers.

Brandon Mathis is a seasoned freelance, full-stack developer from Raleigh, North Carolina. Brandon sat down with the All Things Open team to talk about the evolution and benefits of GraphQL, challenges, considerations, best practices, and much more.

Key takeaways

Introduction to GraphQL

• GraphQL is a query language and runtime for APIs that gained traction around 2016-2017.
• It provides a schema that defines the structure and types of data available, which can simplify the process of querying and interacting with APIs.
• Unlike REST APIs, which often require extensive documentation and can be complex to use, GraphQL’s schema and tools like the GraphIQL Explorer help streamline development and usage.

Benefits of GraphQL

• Reduced documentation overhead: GraphQL’s self-describing nature means that engineers can interact with APIs directly through tools like the GraphIQL Explorer, reducing the need for detailed documentation.
• Increased development efficiency: Brandon noted that using GraphQL improved his turnaround time for API development, as it simplified the interaction between developers and APIs.
• Adoption by major companies: Notable companies such as GitHub, Capital One, PayPal, and Bank of America have adopted GraphQL to streamline their API management and reduce communication overhead.

Challenges and considerations

• Rate limiting: One challenge with GraphQL is managing rate limits due to the potential complexity of queries, which can affect how much data a client can request in a single call.
• Complex queries: The flexible nature of GraphQL queries means that some can be very complex, requiring careful consideration for rate limiting and performance.

Best practices

• Use GraphIQL explorer: This tool helps visualize and test GraphQL queries, making it easier to explore and understand API capabilities without relying solely on documentation.
• Type-oriented specification: Embracing strongly typed languages like TypeScript or Go can enhance the GraphQL experience by leveraging the type-oriented nature of GraphQL.

Local developer community

• Brandon is also involved in the Triangle Developers meetup group in North Carolina, which fosters local developer interaction through events in Durham, Holly Springs, and Raleigh. The group focuses on in-person meetups and networking opportunities for developers in the Research Triangle Park (RTP).
