GraphQL is an API query language that allows clients to ask for exactly what they need and nothing more makes it easier to evolve APIs over time.

This course is divided into three parts, Part 1- Build a GraphQL API, Part 2- Publish Your API, and Part-3 Use Your API. 

In the first part, you will cover topics ranging from basic GraphQL, Building GraphQL Schema, Taking User Input, Adding Flexibility, Making a Change with Mutations, and Going Live with Subscriptions.

In the second part, you will cover topics ranging from Resolution Middleware, Securing with Authentication and Authorization, and Tuning Resolution.

The third part will cover topics ranging from Driving Phoenix Actions with GraphQL, Integrating with the Frontend and GraphQL Types. Upon completing this course, you will have sufficient foundational knowledge of GraphQL, and you can build, publish and use your API in GraphQL.

# Using Relay

If we’re looking for a more opinionated, prepackaged GraphQL framework for our application, **Relay** is the gold standard. With an API that’s been reimagined since its initial release in 2015, it’s lighter, faster, and easier to use than before. Relay Modern, as it’s called, is worth a serious look when we evaluate a GraphQL framework for our application.

Let’s reimplement our PlateSlate user interface using Relay Modern. As with our Apollo example in the previous section, we use the `create-react-app` package to build the boilerplate for our new Relay application. This saves us time:
```
create-react-app plate-slate-relay-ui
```
Once our application is generated, we can verify that the development server is working correctly by going into the directory and running `yarn start`:
```
cd plate-slate-relay-ui
yarn start
```



Up to this point, there’s nothing Relay-related about the application at all. We’ll pull in some basic Relay dependencies we know are needed:

yarn add react-relay
yarn add relay-compiler babel-plugin-relay --dev

The `react-relay` **package** provides the runtime features that Relay needs to interact with the React UI framework. The **`relay-compiler`** and **`babel-plugin-relay`** packages include development utilities that prepare GraphQL queries, schemas, and related tooling for Relay’s use.
Because we need to make some special modifications to our application’s build process, we use the ejection feature from `create-react-app`. This feature unpacks the configuration and scripts that `create-react-app` usually manages for us so we can make changes:
```
yarn eject
```
When we open the `package.json` file, we’ll see that a variety of project configuration options have been added. We make one small change. Look for the `“babel”` section, and add the following `"plugins"` setting:
