Question 1

How do I use libgraphqlparser in a C++ project?

Accepted Answer

After building with CMake and 'make install', include GraphQLParser.h in your code to parse GraphQL queries into ASTs. The 'dump_json_ast' example shows basic usage, but you'll need to integrate the visitor pattern for custom logic.

Question 2

Is libgraphqlparser actively maintained?

Accepted Answer

It is managed under the GraphQL Foundation with a contribution process via EasyCLA, suggesting ongoing maintenance. However, updates may be slow, and the last significant changes should be checked on GitHub for current activity.

Question 3

Can I use libgraphqlparser on Windows?

Accepted Answer

No, the README explicitly states it requires Mac OS X or Linux, so Windows is not officially supported. You might need porting efforts or alternative parsers for cross-platform use.

Question 4

libgraphqlparser vs graphql-js for performance?

Accepted Answer

libgraphqlparser, being C++-based, is likely more performant for parsing in high-throughput C/C++ environments, but graphql-js offers a full JavaScript ecosystem. Choose based on language needs; libgraphqlparser excels as a parser core, not a complete runtime.

Question 5

How to create a Python binding with libgraphqlparser?

Accepted Answer

Use the pure C API from the 'c' subdirectory, as demonstrated in the 'python' example folder. You'll need to write CPython extension code to wrap the C functions, leveraging the AST generation for easy integration.

Question 6

What are the system requirements for libgraphqlparser?

Accepted Answer

Requires a C++11 compiler, CMake, and optionally Flex and Bison. It runs only on Mac OS X or Linux, and testing needs googletest downloaded manually, as per the README instructions.
