Apollo client

npm version Get on Slack

Apollo Client can be used in any JavaScript frontend where you want to use data from a GraphQL server. It's:

  1. Incrementally adoptable, so that you can drop it into an existing JavaScript app and start using GraphQL for just part of your UI.
  2. Universally compatible, so that Apollo works with any build setup, any GraphQL server, and any GraphQL schema.
  3. Simple to get started with, you can start loading data right away and learn about advanced features later.
  4. Inspectable and understandable, so that you can have great developer tools to understand exactly what is happening in your app.
  5. Built for interactive apps, so your users can make changes and see them reflected in the UI immediately.
  6. Small and flexible, so you don't get stuff you don't need. The core is under 25kb compressed.
  7. Community driven, Apollo is driven by the community and serves a variety of use cases. Everything is planned and developed in the open.

Get started on the home page, which has great examples for a variety of frameworks.

Installation

npm install apollo-client

To use this client in a web browser or mobile app, you'll need a build system capable of loading NPM packages on the client. Some common choices include Browserify, Webpack, and Meteor 1.3.

NEW: Install the Apollo Client Developer tools for Chrome for a great GraphQL developer experience!

Running tests locally:

# nvm use node
npm install
npm test

This project uses TypeScript for static typing and TSLint for linting. You can get both of these built into your editor with no configuration by opening this project in Visual Studio Code, an open source IDE which is available for free on all platforms.

Useful tools

Should be moved into some kind of CONTRIBUTING.md soon...

  • AST explorer: you can use this to see what the GraphQL query AST looks like for different queries
