Questions tagged [apollo]

Apollo is a GraphQL client and cache for JavaScript, iOS (Swift) and Android.

Apollo is a flexible, fully-featured client for every platform.

Apollo is made up of a family of technologies you can incrementally add to your stack: Apollo Client to connect data to your UI, Apollo Engine for infrastructure and tooling, and Apollo Server to translate your REST API and backends into a GraphQL schema.

It has implementations for JavaScript, iOS and Android. The JavaScript client has integrations for React, Angular, Vue.js, Ember.js and more.

Apollo is fully compatible with any server that implements the GraphQL specification.
