Guide for building applications with Apollo Kotlin, the GraphQL client library for Android and Kotlin. Use this skill when: (1) setting up Apollo Kotlin in a Gradle project for Android, Kotlin/JVM, or KMP, (2) configuring schema download and codegen for GraphQL services, (3) configuring an `ApolloClient` with auth, interceptors, and caching, (4) writing queries, mutations, or subscriptions,
Skill body
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
ApolloClientwith auth, logging, and caching. - Implement operations.
- Validate behavior with tests and error handling.
Reference Files
- Setup - Gradle plugin, schema download, codegen config (including scalars), client configuration (auth, logging, interceptors)
- Operations - Queries, mutations, subscriptions, and how to execute them
- Caching - Setup and use the normalized cache
- Migration Guide - Migrate from Apollo Kotlin 4
Scripts
- list-apollo-kotlin-versions.sh - List versions of Apollo Kotlin
- list-apollo-kotlin-normalized-cache-versions.sh - List versions of the Apollo Kotlin Normalized Cache library
Key Rules
- Prefer Apollo Kotlin v5+. Do not use v3 or older versions.
- Keep schema and operations in source control to make builds reproducible.
