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.

# PlateSlate application

For the rest of the course, we’ll be focusing on improving a given **PlateSlate** application. **PlateSlate** models the menu, ordering, and order fulfillment needs of a quick-service restaurant chain. We’ll incrementally build out the domain model and add features to its API that will expose us to deeper, trickier aspects of **GraphQL** and **Elixir**.

We’re also going to leverage a couple of packages to expose our GraphQL API through the web, specifically, **Plug** and **Phoenix**.


Finally, we’ll use some packages to obtain underlying data. One of the core value propositions of GraphQL is its ability to provide a common interface to different types of data stores. We’ll try to illustrate this as we build our application. This means we’ll eventually use a basic **HTTP** client to make **HTTP** requests to other **APIs**. We'll also use **Ecto** to access an **SQL database**. Strong proficiency with these packages is not required, but a basic grasp of how to interact with a relational database will help you get the most out of this course.
