A demonstration Rails application implementing a GraphQL API using the graphql-ruby gem.
graphql-ruby-demo is a demonstration Ruby on Rails application that implements a GraphQL API using the graphql-ruby gem. It shows how to define a GraphQL schema, handle queries through a Rails controller, and integrate the GraphiQL IDE for interactive exploration. The project solves the problem of understanding practical GraphQL setup in a Rails environment by providing a complete, runnable example.
Ruby on Rails developers who want to learn or reference how to build GraphQL APIs in their applications, especially those new to GraphQL or the graphql-ruby library.
Developers choose this demo because it offers a straightforward, production-like example with clear code organization and immediate deployability, reducing the learning curve for GraphQL integration in Rails compared to starting from scratch or relying solely on documentation.
Use graphql-ruby to expose a Rails app
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a complete, runnable Rails app with GraphQL schema in `/app/graph` and query handling in `queries#create`, making real implementation patterns easy to inspect.
Integrates GraphiQL IDE via graphiql-rails, allowing developers to explore and test the API interactively without additional setup.
Deployed on Heroku at http://graphql-ruby-demo.herokuapp.com/, offering immediate access to a working GraphQL endpoint for experimentation.
Built on the widely used graphql-ruby gem, ensuring relevance and compatibility with common Rails workflows.
Focuses only on basic queries and schema definition, with no examples of mutations, subscriptions, or complex GraphQL features needed for production.
The README is minimal, providing links but no in-depth explanations or tutorials, which can leave learners struggling to understand implementation details.
Code is tailored for demonstration and lacks production considerations like robust error handling, authentication, or performance optimizations.
