:robot: A strongly-typed, caching GraphQL client for the JVM, Android and Kotlin multiplatform

Apollo Android

Apollo Android is a GraphQL client that generates Java and Kotlin models from GraphQL queries. These models give you a type-safe API to work with GraphQL servers. Apollo helps you keep your GraphQL query statements together, organized, and easy to access.

This library is designed primarily with Android in mind, but you can use it in any Java/Kotlin app.

Features

• Java and Kotlin code generation
• Queries, Mutations and Subscriptions
• Reflection-free parsing of responses
• HTTP cache
• Normalized cache
• File uploads
• Custom scalar types
• Support for RxJava2, RxJava3, and Coroutines

Getting started

If you are new to GraphQL, check out the tutorial that will guide you through building an Android app using Apollo, Kotlin and coroutines.

If you'd like to add Apollo Android to an existing project:

• Get started with Kotlin shows how to add Apollo Android to a Kotlin project.
• Get started with Java shows how to add Apollo Android to a Java project.
• Get started with Multiplatform (Experimental) shows how to add Apollo Android to a Multiplatform project. This is still under heavy development and APIs may change without warning.

Advanced topics

Check the project website for in depth documentation about caching, plugin configuration, android, file upload, coroutines, rxjava2, rxjava3, persisted queries, no runtime, migrations and much more...

IntelliJ Plugin

The JS Graphql IntelliJ Plugin provides auto-completion, error highlighting, and go-to-definition functionality for your .graphql files. You can create a .graphqlconfig file to use GraphQL scratch files to work with your schema outside product code (such as to write temporary queries to test resolvers).

Releases

The latest version is

Check the changelog for the release history.

Releases are hosted on Jcenter and Maven Central. The plugin is additionally hosted on the Gradle Plugin Portal

plugins {
  id("com.apollographql.apollo").version("x.y.z")
}

repositories {
  jcenter()
}

dependencies {
  implementation("com.apollographql.apollo:apollo-runtime:x.y.z")

  // optional: if you want to use the normalized cache
  implementation("com.apollographql.apollo:apollo-normalized-cache-sqlite:x.y.z")
  // optional: for coroutines support
  implementation("com.apollographql.apollo:apollo-coroutines-support:x.y.z")
  // optional: for RxJava3 support  
  implementation("com.apollographql.apollo:apollo-rx3-support:x.y.z")
  // optional: if you just want the generated models and parsers and write your own HTTP code/cache code, you can remove apollo-runtime
  // and use apollo-api instead  
  implementation("com.apollographql.apollo:apollo-api:x.y.z")
}

Latest development changes are available in Sonatype's snapshots repository:

repositories {
  maven { 
    url = uri("https://oss.sonatype.org/content/repositories/snapshots/")
  }
}
