GraphQL server libraries are essential tools for building GraphQL APIs in Node.js applications. They provide the necessary infrastructure to define schemas, handle queries and mutations, and manage data fetching. Both Apollo Server and Express-GraphQL are popular choices, each with its unique features and strengths. Apollo Server is designed for ease of integration with various data sources and offers advanced features like caching and real-time subscriptions. In contrast, Express-GraphQL is a lightweight middleware that allows developers to quickly set up a GraphQL server within an existing Express application, focusing on simplicity and minimalism.

Feature Comparison: apollo-server-express vs express-graphql
Integration
apollo-server-express: Apollo Server provides seamless integration with various data sources, including REST APIs, databases, and other GraphQL services. It supports schema stitching and allows for easy federation of multiple GraphQL services, making it ideal for microservices architecture.
express-graphql: Express-GraphQL is designed to work as middleware within an existing Express application. It allows developers to quickly add GraphQL capabilities without extensive configuration, making it easy to integrate into existing Express projects.
Performance Optimization
apollo-server-express: Apollo Server includes built-in performance optimization features such as query batching, caching, and automatic persisted queries. These features help reduce the number of requests and improve response times, making it suitable for high-performance applications.
express-graphql: Express-GraphQL is lightweight and does not come with built-in performance optimizations. However, developers can implement custom optimizations as needed, providing flexibility but requiring more manual effort to achieve optimal performance.
Real-time Capabilities
apollo-server-express: Apollo Server supports real-time capabilities through subscriptions, allowing developers to build applications that can push updates to clients in real time. This is particularly useful for applications that require live data updates, such as chat applications or collaborative tools.
express-graphql: Express-GraphQL does not natively support subscriptions, making it less suitable for applications that require real-time features. Developers would need to implement additional libraries or solutions to achieve similar functionality.
Community and Ecosystem
apollo-server-express: Apollo Server has a large and active community, with extensive documentation and a rich ecosystem of tools and libraries. This makes it easier for developers to find resources, tutorials, and support when building GraphQL APIs.
express-graphql: Express-GraphQL has a smaller community compared to Apollo Server, but it benefits from the broader Express ecosystem. While documentation is available, it may not be as comprehensive as that of Apollo Server.
Learning Curve
apollo-server-express: Apollo Server has a steeper learning curve due to its extensive feature set and configuration options. Developers may need to invest time in understanding its advanced capabilities, especially when integrating with various data sources and implementing caching strategies.
express-graphql: Express-GraphQL is straightforward and easy to learn, making it an excellent choice for developers who are new to GraphQL. Its simplicity allows for quick setup and understanding, enabling developers to focus on building their GraphQL schema and resolvers.
How to Choose: apollo-server-express vs express-graphql
apollo-server-express: Choose Apollo Server if you need a robust solution that offers advanced features like caching, subscriptions, and easy integration with various data sources. It is ideal for applications that require a rich set of tools for managing GraphQL operations and optimizing performance.
express-graphql: Choose Express-GraphQL if you want a lightweight and straightforward solution for adding GraphQL to an existing Express application. It is best suited for projects that prioritize simplicity and minimal overhead, allowing for quick setup and easy integration.

This makes it an excellent choice for building scalable and maintainable APIs that can serve complex data requirements.
An alternative to apollo-server-express is express-graphql. This library provides a simple way to create a GraphQL API using Express. It allows developers to define a GraphQL schema and handle queries and mutations directly within their Express application. While express-graphql is lightweight and straightforward, it may not offer the same level of features and integrations as apollo-server-express. However, it is a great choice for developers who prefer a minimalistic approach and want to quickly set up a GraphQL server without additional overhead.
express-graphql is a middleware for integrating GraphQL with Express.js, allowing developers to build GraphQL APIs easily and efficiently. It provides a straightforward way to set up a GraphQL server, enabling developers to define their schema and resolvers while leveraging the power of Express.js for handling HTTP requests. With express-graphql, you can quickly create a robust GraphQL endpoint that can serve complex data queries and mutations.
While express-graphql is a popular choice for building GraphQL APIs, there are other libraries that serve similar purposes. Here are a few alternatives:
apollo-server-express is part of the Apollo Server ecosystem, which is widely used for building GraphQL APIs. It integrates seamlessly with Express.js, providing a rich set of features such as built-in support for subscriptions, caching, and performance tracing.

graphql-yoga is a fully-featured GraphQL server that is easy to set up and use. It is built on top of Express.js and provides a simple API for creating GraphQL servers with features like real-time subscriptions, file uploads, and more. graphql-yoga is designed to be flexible and extensible, making it suitable for both small projects and larger applications. Its simplicity and ease of use make it a great option for developers looking to get started with GraphQL quickly.
This is the Express integration of Apollo Server. Apollo Server is a community-maintained open-source GraphQL server that works with many Node.js HTTP server frameworks. Read the docs. Read the CHANGELOG.
A full example of how to use apollo-server-express can be found in the docs.
Before Apollo Server 3, we officially supported using this package with connect as well. connect is an older framework that express evolved from. For now, we believe that this package is still compatible with connect and we even run tests against connect, but we may choose to break this compatibility at some point without a major version bump. If you rely on the ability to use Apollo Server with connect, you may wish to make your own integration.
Principles
GraphQL Server is built with the following principles in mind:
By the community, for the community: GraphQL Server's development is driven by the needs of developers
Simplicity: by keeping things simple, GraphQL Server is easier to use, easier to contribute to, and more secure
Performance: GraphQL Server is well-tested and production-ready - no modifications needed
