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 Angular project with
angular-cli, a popular command-line tool that gives you a blank project with all required build configuration already setup.
In the Clients section in the GraphQL part, we already covered the responsibilities of a GraphQL client on a higher level, now it’s time to get 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, you pretty much have the choice between Apollo Client and Relay.
The most common question heard from people that are getting started with GraphQL on the frontend is which GraphQL client they should use. We’ll try to provide a few hints that’ll help you decide which of these clients is the right one for your next project!
The performance benefits of Relay come at the cost of a notable learning curve. Relay is a pretty complex framework and understanding all its bits and pieces does require some time to really get into it. The overall situation in that respect has improved with the release of the 1.0 version, called Relay Modern, but if you’re for something to just get started with GraphQL, Relay might not be the right choice just yet.
