GraphQL, the open source query language, has been steadily growing in popularity over the past few years. The language is excellent for frontend development, as it creates a usable interface to fetch precisely the data required for the specific client at hand. You can also use it to aggregate multiple backend services and data sources.

Studies show that the ecosystem around GraphQL is maturing—it has a very global user base and a growing number of tools exist to aid in its adoption. The 2022 State of GraphQL Report found that 61.8% of developers are happy with the overall state of the ecosystem. Yet many native GraphQL features go unused by developers, which suggests there is a wide range of experience levels, from novice to advanced users, working with the technology. This indicates there is plenty of room for growth and knowledge sharing.

Below, I’ll review the key takeaways from the 2022 State of GraphQL Report, considering overall usage data and focusing on the popularity of specific features. We’ll also highlight the state of standard tools used in conjunction with GraphQL to get the job done.

Analyzing Overall Usage Statistics

First off, there is a wide variance in the types of GraphQL APIs in production today, ranging from private to public endpoints. The report found 47.9% of developers use GraphQL for exposing an API intended for a personal website or app, 40.4% use it for private unexposed APIs for internal usage and 19.5% use GraphQL for publicly available APIs intended for third-party developer consumption. This demonstrates its flexibility to cater to multiple scenarios. And while the majority of clients that connect to GraphQL APIs include browsers (62.3%), it’s commonly consumed by other client types such as native mobile apps, other servers and desktop apps.

Previously, we discussed using GraphQL as a composition layer to combine underlying APIs and services. And the report backs up this idea that developers commonly use it to aggregate various data sources: 55.4% of GraphQL APIs hit databases, while 35% consume REST APIs and 14.6% eat other GraphQL endpoints.

In terms of benefits, one strong point is the ability to enforce and validate types for every object in the API. Users find other top benefits to be avoiding overfetching and aggregating requests. Yet, some hurdles still present themselves. These top drawbacks include error handling, performance issues, client-side caching and security woes.

Regarding user base statistics, most users have been working with GraphQL for less than five years. If we look at the type of sector utilizing GraphQL, we see it primarily leveraged in the programming and technology sector. This is followed by e-commerce and retail (16.4%), finance (8.9%) and news, media and blogging (7.2%).

Many Advanced Features Go Unused

Many of the more advanced GraphQL features still go unnoticed by the majority of users. For example, live queries is a feature that helps obtain live data from a GraphQL server, yet only 25% who know about it have used it. Over half of respondents had never heard of @skip, a directive that skips a field based on a value passed to it. Similarly, other directives like @specifiedBy, @defer and @stream also share little-to-no awareness or use.

Analyzing feature usage becomes a bit more serious if we consider the unadopted security and performance features. For example, only 43.2% of respondents have disabled query introspection. Disabling query introspection is a suggested security best practice to limit a hacker’s ability to perform surveillance. But as we’ve previously covered, security by obscurity isn’t enough to protect GraphQL, and an additional security emphasis is often needed.

As most GraphQL APIs are intended for personal or private scenarios, you would think that more security features would be leveraged to limit the threat of introspection and denial-of-service attacks. Yet, the report discovered low usage and awareness of security and performance features like query timeouts, query rate limiting and query cost analysis, all of which could be turned on to curb malicious behaviors.

Tools Used In Conjunction With GraphQL

Developers often seek to combine, aggregate or merge GraphQL schemas from different APIs. To do so, Apollo Federation is the most common solution, used by 22.5% of respondents. This is followed by Schema Stitching (16.9%), GraphQL Modules (4.4%), and GraphQL Mesh (2.9%).

Looking at other technologies used in connection, Next.js is the most popular framework and PostgreSQL is the most common database used. TypeScript and JavaScript comprise the most common languages used to write a GraphQL backend. Developers also use a balanced mix of IDEs to query and test endpoints, including GraphiQL, GraphQL Playground, Postman, Apollo Studio, and Insomnia.

The report also found relatively high usage and retention for tools like the GraphQL Code Generator schema builder, Apollo Client and Apollo Server. The data shows a crowded solution market with Apollo as an industry-leading outlier—many other clients, servers, API generators and schema builders have medium-to-high retention rates yet experience far less use.

Final Thoughts

The 2022 State of GraphQL Report sheds some interesting light on the state of GraphQL, validating a lot of the interest and trends we’ve covered lately on the blog. Of course, there is more to be said about many areas, such as smoothing the transition to GraphQL.

One key finding is the low number of security features being leveraged by developers. A greater emphasis on API security is required to avoid incidents and retain a zero-trust approach. This emphasis is part and parcel of responding to ongoing software supply chain threats and will require more awareness and thought leadership around GraphQL security best practices.

The 2022 State of GraphQL survey ran from June 15, 2022, to July 15, 2022, and collected 3,094 responses. The above analysis only scratched the surface and there are many other insights. For more findings, you can read the full results here.
