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.

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.

apollo-federation

Apollo Federation enables composing multiple GraphQL APIs (subgraphs) into a unified supergraph.

Apollo iOS is a strongly-typed GraphQL client for Apple platforms. It generates Swift types from your GraphQL operations and schema, and ships an async/await client, a normalized cache (in-memory or SQLite-backed), a pluggable interceptor-based HTTP transport that handles queries, mutations, and multipart subscriptions, and an optional WebSocket transport ( graphql-transport-ws ) that can carry any operation type.

Apollo Router is a high-performance graph router written in Rust for running Apollo Federation 2 supergraphs. It sits in front of your subgraphs and handles query planning, execution, and response composition.
