Apollo Kotlin Guide

Apollo Kotlin is a strongly typed GraphQL client that generates Kotlin models from your GraphQL operations and schema, that can be used in Android, JVM, and Kotlin Multiplatform projects.

Process

Follow this process when adding or working with Apollo Kotlin:

• Confirm target platforms (Android, JVM, KMP), GraphQL endpoint(s), and how schemas are sourced.
• Configure Gradle and code generation, including custom scalars
• Create a shared ApolloClient with auth, logging, and caching.
• Implement operations.
• Validate behavior with tests and error handling.
