What the study found
The study found that GraphQLify, an automated framework for moving REST APIs to GraphQL, could convert APIs while preserving end-to-end type safety. It also generated an embedded server that directly invokes API code rather than using a separate adapter server.
Why the authors say this matters
The authors say this matters because GraphQL is a schema-based, strongly typed query language that can support efficient client-server communication, and preserving type safety is described as a core advantage of adopting it. They also suggest that avoiding separate adapter servers matters because it removes performance overhead from dynamic request binding and network latency.
What the researchers tested
The researchers evaluated GraphQLify on 834 APIs from nine popular open-source projects. They compared it with OASGraph, the current state-of-the-art tool in the abstract, and also measured performance for workflows requiring five sequential API calls.
What worked and what didn't
GraphQLify successfully converted 100% of the tested APIs with zero type mismatches. By comparison, OASGraph had a 3.5% failure rate and a 42% type mismatch rate on the same dataset. For five sequential API calls, GraphQLify reduced data-fetching time by a factor of 2 to 4 versus REST.
What to keep in mind
The abstract does not describe limitations beyond the reported evaluation setting. The results are based on the specific set of 834 APIs from nine open-source projects and the performance test described in the abstract.
Key points
- GraphQLify is an automated framework for migrating REST APIs to GraphQL.
- It uses static source code analysis for type inference and generates an embedded server.
- In the evaluation, it converted 100% of 834 APIs with zero type mismatches.
- OASGraph had a 3.5% failure rate and a 42% type mismatch rate on the same dataset.
- For five sequential API calls, GraphQLify cut data-fetching time by a factor of 2 to 4.
