NOTE: This tutorial uses the legacy version of Graphcool and will be updated soon to use the new Graphcool Framework. The CLI commands mentioned in tutorial are outdated, you can read more about the new CLI here. If you still want to go through this tutorial, you can install the old version of the CLI using
npm install -g email@example.com.
In the previous tutorials, you learned about major concepts and benefits of GraphQL. Now is the time to get your hands dirty and start out with an actual project!
You’re going to build a simple clone of Hackernews. Here’s a list of the features the app will have:
In this track, you’ll use the following technologies for building the app:
You’ll create the Ember project with ember-cli, the command line interface for ambitious web applications.
ember-cli will start you off with a blank project with all required build configuration already setup.
In the Clients section in the GraphQL part, you already covered the responsibilities of a GraphQL client on a higher level, now it’s time to get bit more concrete.
In short, you should use a GraphQL client for tasks that are repetitive and agnostic to the app you’re building. For example, being able to send queries and mutations without having to worry about lower-level networking details or maintaining a local cache. This is functionality that you’ll want in any frontend application that’s talking to a GraphQL server - why build it yourself if you can use one of the amazing GraphQL clients out there?
There are a few GraphQL client libraries available. For very simple use cases (such as writing scripts),
graphql-request might already be enough for your needs. However, chances are that you’re writing a somewhat larger application where you want to benefit from caching, optimistic UI updates, and other handy features. In these cases, Apollo Client is the only solution that currently works with Ember.
This tutorial will use the
ember-apollo-client library which is an
ember-cli add-on that exposes a service to interact with Apollo.
ember-apollo-client is still in it’s infancy so not all Apollo features have been implemented. The most notable feature of which is subscriptions. This tutorial will be updated as features are added to the library, so continually check back for new sections!
