Apollo Client is a fully-featured caching GraphQL client with integrations for React, Angular, and more. It allows you to easily build UI components that fetch data via GraphQL. To get the most value out of
apollo-client, you should use it with one of its view layer integrations.
To get started with the React integration, go to our React Apollo documentation website.
Apollo Client also has view layer integrations for all the popular frontend frameworks. For the best experience, make sure to use the view integration layer for your frontend framework of choice.
- Universally compatible, so that Apollo works with any build setup, any GraphQL server, and any GraphQL schema.
- Simple to get started with, so you can start loading data right away and learn about advanced features later.
- Inspectable and understandable, so that you can have great developer tools to understand exactly what is happening in your app.
- Built for interactive apps, so your users can make changes and see them reflected in the UI immediately.
- Small and flexible, so you don't get stuff you don't need. The core is under 25kb compressed.
- Community driven, because Apollo is driven by the community and serves a variety of use cases. Everything is planned and developed in the open.

You get started by constructing an instance of the core class
ApolloClient. If you load
ApolloClient from the
apollo-boost package, it will be configured with a few reasonable defaults such as our standard in-memory cache and a link to a GraphQL API at
;const client = ;
ApolloClient at a different URL, add your GraphQL API's URL to the
uri config property:
;const client =uri: '';
Most of the time you'll hook up your client to a frontend integration. But if you'd like to directly execute a query with your client, you may now call the
client.query method like this:
Now your client will be primed with some data in its cache. You can continue to make queries, or you can get your
client instance to perform all sorts of advanced tasks on your GraphQL data. Such as reactively watching queries with
watchQuery, changing data on your server with
mutate, or reading a fragment from your local cache with
To learn more about all of the features available to you through the
apollo-client package, be sure to read through the
apollo-client API reference.
