We know this can be confusing, so we’re working to improve our documentation and add more code samples that aren’t written in JavaScript. GraphQL was introduced at a React conference and GraphQL.js is one of the most widely used implementations to date. It’s understandable why you’d think this, though. Our Code page contains a long list of libraries in many different programming languages to help with that. GraphQL is a specification that can be implemented in any language. Is GraphQL only for React or JavaScript developers? # We also have a free online course with edX, Exploring GraphQL: A Query Language for APIs.īefore you start your learning journey, make sure you know what an API is and how communication generally works between client and server.

In our documentation, you’ll find a series of articles that explain essential GraphQL concepts and how they work. There are many resources available to help you learn GraphQL, including this website. These data sources could be remote APIs, databases, local cache, and nearly anything else your programming language can access.įor more information on how to get GraphQL to interact with your database, check out our documentation on resolvers. Generally, these resolver functions should delegate to a business logic layer responsible for communicating with the various underlying data sources. GraphQL coordinates and aggregates the data from these resolver functions, then returns the result to the client. Accessing and manipulating data is performed with arbitrary functions called resolvers. Unlike SQL, GraphQL is agnostic to the data source(s) used to retrieve data and persist changes. GraphQL is a specification typically used for remote client-server communications. Is GraphQL a database language like SQL? # This can be done by masking your REST endpoint into a GraphQL endpoint using root resolvers.įor an opinionated perspective on how GraphQL compares to REST, check out How To GraphQL. For example, you can abstract REST APIs behind a GraphQL server. GraphQL and REST can actually co-exist in your stack. GraphQL is often considered an alternative to REST, but it’s not a definitive replacement. They both handle APIs and can serve similar purposes from a business perspective. We recommend focusing on one use case at first and only building the part of the schema needed for that. Your GraphQL schema and business domain model can expand gradually. For instance, starting with a single HTTP request that wraps an existing REST call. You can try out GraphQL without rewriting your entire application. Our homepage outlines even more reasons to use GraphQL. Access to a powerful tooling ecosystem with GUIs, editor integrations, code generation, linting, analytics, and more.Reduce the need for breaking changes, but utilize a built-in mechanism for deprecations when you need to.Ensure that all of your data is statically typed and these types inform what queries the schema supports.Create a representation of your data that feels familiar and natural ( a graph).Aggregate data from multiple UI components.It depends on your use case, but in general, GraphQL has a few key features that stand out.
