In short, this is a GraphQL request JSON body builder for Kotlin. It will generate the JSON string for request body that work with GraphQL Server. For example, we have the GraphQL query for list all the notes.

    query {
        notes {
            id
            createdDate
            content
            author {
                name
                avatarUrl(size: 100)
            }
        }
    }

And here is how we write it in Kotlin using Kraph.

    Kraph {
        query {
            fieldObject("notes") {
                field("id")
                field("createdDate")
                field("content")
                fieldObject("author") {
                    field("name")
                    field("avatarUrl", mapOf("size" to 100))
                }
            }
        }
    }

As you can see, we can achieve our goal with just a few tweaks from the original query.

NOTE: Kraph is still in an early stage. The usage may change in further development.

• DSL builder style. Make it easier to read and use.
• Support both Query and Mutation operation.

Adding Kraph to build.gradle

    repositories {
        jcenter()
    }
    
    dependencies {
        compile "com.taskworld.kraph:kraph:x.y.z"
    }

Please see the example from sample folder for now. We will update this part ASAP.
