Integrate GraphQL to the Ruby on Rails Application

In this project, we’ll create a simple application that allows users to create groups among themselves. The users will be able to split bills among the members of a group using this application. We’ll use Ruby on Rails along with GraphQL to create this application to split bills among different groups. Ruby on Rails is famous for its fast development and ease of debugging, and GraphQL is widely used for its efficient and precise data fetching with strong-typed schema.

First, we'll test and embed multiple GraphQL queries. Then, we'll execute some simple GraphQL mutations. After that, we'll implement the queries and mutations for the models that are interdependent on each other. In the end, we'll write some complex mutations and queries using connected nodes (a mediator model depending on more than one model) in GraphQL.

This project will help us develop skills to build applications in Ruby on Rails, which is very popular for developing SaaS applications and using GraphQL with it, which can be utilized within that SaaS application to expose its data and functionality through a GraphQL API.
