The short answer

Choose GraphQL.js if you need…

  • JavaScript or TypeScript developers building a GraphQL API on Node.js
  • Developers who want the reference implementation that other GraphQL tools are built on
  • Teams building browser-side tools that work with GraphQL schemas

Choose Yoga if you need…

  • Developers embedding flexbox-style layout into a native or cross-platform app
  • Teams who want the same layout rules across several languages
  • Contributors who want to work on the C++ layout core and its unit tests

What each one is

GraphQL.js

GraphQL.js is the official JavaScript implementation of GraphQL, a query language for APIs originally created by Facebook. It lets developers define a typed schema that maps to their code, then run queries against that schema, with validation of queries before they execute. It works in both Node.js servers and browsers.

Yoga

Yoga is an embeddable flexbox layout engine. It calculates where each element goes and how big it should be, so other software can place items on screen without writing its own layout logic. The README describes it as having bindings for multiple languages, and it is available through npm, Maven Central, and Swift Package Manager.

Best for

GraphQL.js

  • JavaScript or TypeScript developers building a GraphQL API on Node.js
  • Developers who want the reference implementation that other GraphQL tools are built on
  • Teams building browser-side tools that work with GraphQL schemas

Yoga

  • Developers embedding flexbox-style layout into a native or cross-platform app
  • Teams who want the same layout rules across several languages
  • Contributors who want to work on the C++ layout core and its unit tests

Strengths

GraphQL.js

  • Maintained as the reference implementation of the GraphQL specification for JavaScript
  • Ships both CommonJS and ES module builds, so it works with most bundlers
  • Released under the permissive MIT license

Yoga

  • Based on flexbox, a layout model many developers already know
  • Available through several package ecosystems (npm, Maven Central, SPM)
  • MIT licensed and widely starred

Not ideal for

GraphQL.js

  • People who only want to call an existing GraphQL API and do not write server code; a client library would fit better
  • Non-developers, since the README assumes familiarity with JavaScript and schemas

Yoga

  • People who just want to build a web page; the README does not describe a standalone website tool
  • Non-programmers, since it is a code library with no visual interface

Trade-offs

GraphQL.js

  • The README's getting-started material is brief; fuller documentation is on external sites
  • Building a full API typically needs additional libraries not covered in this README
  • Contributions require signing a GraphQL Specification Membership agreement

Yoga

  • The README is short and gives little detail on the API or bindings
  • Building requires C++ 20 and CMake, which is not trivial for beginners
  • Latest release has no prebuilt binaries, so you typically build or install through a package manager
