graphql-libgraphqlparser

Make graphql faster with libgraphqlparser. Ruby bindings to a C-level GraphQL parser.

It's faster:

~/projects/graphql-libgraphqlparser $ bundle exec ruby benchmark.rb
              user     system      total        real
Ruby      0.090000   0.000000   0.090000 (  0.088713)
C         0.010000   0.000000   0.010000 (  0.012827)
~/projects/graphql-libgraphqlparser $ bundle exec ruby benchmark.rb
              user     system      total        real
Ruby      0.090000   0.010000   0.100000 (  0.090548)
C         0.010000   0.000000   0.010000 (  0.013126)
~/projects/graphql-libgraphqlparser $ bundle exec ruby benchmark.rb
              user     system      total        real
Ruby      0.080000   0.000000   0.080000 (  0.090066)
C         0.020000   0.000000   0.020000 (  0.011790)
~/projects/graphql-libgraphqlparser $ bundle show graphql
~/.rbenv/versions/2.1.0/lib/ruby/gems/2.1.0/gems/graphql-0.19.4

Installation

This gem depends on libgraphqlparser (>= 0.5.0). You can install it a few ways:

• Homebrew: brew install libgraphqlparser

• From Source:

  wget https://github.com/graphql/libgraphqlparser/archive/v0.5.0.tar.gz
  tar -xzvf v0.5.0.tar.gz
  cd libgraphqlparser-0.5.0/ && cmake . && make && make install
  

• With heroku-buildpack-libgraphqlparser

Then, install this gem:

gem "graphql-libgraphqlparser"

When you require this gem, it overrides GraphQL.parse:

require "graphql/libgraphqlparser"

Libgraphqlparser versions

The Ruby gem expects certain versions of libgraphqlparser to be installed. I couldn't figure out how to check this in extconf.rb, so I documented it here:

libgraphqlparser version	graphql-libgraphqlparser(Ruby gem) version

= 0.5.0 | 0.5.0 <= 0.4.0 | 0.4.0
