  • Which is Better? : GraphQL vs. REST API

    Sep 22, 2023

    Choosing the appropriate application programming interface (API) is similar to choosing the best tool for the task in the constantly changing world of web development. GraphQL and REST API are two competitors that have developed in recent years. The decision between them is important because both have unique advantages and meet various needs. We will examine GraphQL and REST API's traits, histories, distinctions, difficulties, benefits, and ideal use cases in this article. By the end, you'll be better prepared to make a choice depending on the specifications of your project.

    What is GraphQL?

    A query language for your API is GraphQL. Think of it as your own personal data steward. With GraphQL, customers are given the ability to just request the data they require, as opposed to receiving predefined sets of data from numerous endpoints. Imagine placing an order for a personalized sandwich; you get precisely what you want, neither more nor less.

    One of GraphQL's unique characteristics is its adaptability. It decreases the number of roundtrips to the server by enabling clients to request numerous resources in a single query. This capability is very useful when developing mobile apps or other situations where optimizing data transfer is essential.

    What is REST API?

    Representational State Transfer, sometimes known as REST API, is a well-known architectural design approach for creating networked applications. Statelessness, client-server communication, and standardized interfaces are just a few of the restrictions it is dependent upon. Clients communicate with the resources that REST APIs offer as endpoints using HTTP methods like GET, POST, PUT, and DELETE.

    REST's simplicity and predictability are its strongest points. Similar to ordering from a menu, you are aware of the options and are aware of the endpoints for each resource. However, in situations when clients require different combinations of data, this simplicity can also result in inefficiencies.

    The History of REST

    We must go back to the early 2000s when Roy Fielding first introduced REST in his Ph.D. dissertation in order to comprehend its relevance. The architectural requirements for REST prioritize clarity, scalability, and simplicity. Because of these features, it became a popular choice for web developers and expanded quickly. The de facto standard for web APIs is REST.

    The History of GraphQL

    In contrast, GraphQL is a relative newcomer. It was created in-house by Facebook in 2012, and when it was open-sourced in 2015, it joined the GraphQL Foundation. The shortcomings of REST, notably the over- or under-fetching of data, were addressed with the development of GraphQL. It provides a flexible query language that enables users to make a single query that precisely requests the data they require.

    Since its launch, GraphQL has progressively grown in popularity, especially among developers of cutting-edge web and mobile applications. Developers looking for effective data retrieval have found it to be an attractive option thanks to its capacity to optimize data transport.

    How GraphQL Differs from REST

    The way data is requested differs significantly between GraphQL and REST. REST allows clients to fetch distinct data chunks by sending several requests to various endpoints. As opposed to this, GraphQL combines these requests into a single request, considerably lowering network overhead.

    Think of the grocery store analogy to demonstrate this distinction. In a RESTful situation, you would need to go to several shops to buy everything on your shopping list. In the world of GraphQL, you would enter a single store with a magic basket that automatically filled itself with all the products on your list, saving you from making additional journeys.

    Challenges of Adopting GraphQL

    Although GraphQL has many benefits, implementing it has its own set of difficulties. The learning curve is one of the most noticeable. REST-experienced developers can initially find the switch to GraphQL to be a bit intimidating. In addition, poorly optimized searches run the danger of over-fetching data.

    Challenges of Adopting REST API

    The REST API has its own set of difficulties. Clients may over- or under-fetch data as a result of the fixed structure of endpoints. Versioning REST APIs can be challenging as well because changes may affect current customers.

    Advantages of GraphQL

    The benefits of GraphQL stand out in situations where adaptability is crucial. It enables users to only request the data they actually require, minimizing unnecessary data transfer. The creation of mobile apps, where bandwidth and data utilization are important factors, benefits particularly from this efficiency.

    Advantages of REST API

    With its well-established protocols, the REST API thrives in scenarios where simplicity and caching are crucial considerations. It's a good option for public APIs as well because of how developer-friendly its structure is. REST's statelessness fits in nicely with caching techniques, which improves efficiency even more.

    Use Cases: When to Choose GraphQL

    Complex Applications: GraphQL's flexibility shines when creating sophisticated apps with various data needs. Developers can use it to streamline data retrieval and make sure that clients only get the information they require.

    Mobile Applications: GraphQL's exact data requests are a big plus for mobile app development, where bandwidth and data utilization are crucial. The reduction of data transfer makes apps speedier and more effective.

    Data Aggregation: GraphQL makes the process easier if your application wants to combine data from various sources or databases. It streamlines the data layer of your application by serving as a common hub for obtaining data from numerous backends.

    Use Cases: When to Stick With REST API

    Simple APIs: REST remains a good option for simple APIs with set data structures. The simplicity of REST's approach is useful when clients' data needs can be satisfied using established endpoints.

    Public APIs: REST's predictability and usability make it an excellent fit when developing APIs for partners or third-party developers. Your API should be designed such that any developers using it can immediately understand how to send queries and receive data.

    Caching Requirements: The statelessness of REST matches nicely with caching technologies if your application depends extensively on caching to enhance performance and lower server load. It makes caching techniques easier to implement.

    Examples of companies using GraphQL successfully

    Several prominent companies have successfully implemented GraphQL into their tech stacks, reaping the benefits of its flexible and efficient data querying capabilities. Here are some examples of companies that have embraced GraphQL:

    Facebook: As the birthplace of GraphQL, it's no surprise that Facebook heavily utilizes this technology. They use GraphQL to power their mobile applications, enabling efficient data retrieval and reducing over-fetching of information.

    GitHub: GitHub, the popular platform for version control and software development collaboration, adopted GraphQL to provide its users with more flexible and customizable data queries. GraphQL allows developers to fetch exactly the data they need when working with repositories and issues.
