Now that we've gone over the basic concepts of GraphQL, 0:00 we're almost ready to run our first query. 0:03 But before we do, I'm gonna give you a tour of the environment we'll be using in 0:06 this course to run and test our queries. 0:10 It's called Launchpad, and if you're familiar with sandbox tools, 0:13 like JS pin or Code pin, you'll be right at home. 0:17 With Launchpad, we can run one off queries and see the results 0:21 without the overhead of setting up and deploying a full GraphQL server. 0:25 To get started, go to launchpad.graphql.com in your browser. 0:30 If you've never been here before, you'll be greeted with a welcome message 0:39 that briefly explains what Launchpad is used for, and 0:43 contains a link to the awesome Launchpad repo. 0:46 The awesome Launchpad repo is where the official Launchpad docs are hosted. 0:49 If we go ahead and follow that link, we can find a ton of great resources such 0:54 as Launchpad starter projects and real world examples for GraphQL. 0:59 Now let's head back to our Launchpad tab. 1:08 There are three basic parts to Launchpad UI. 1:14 The backend editor, the query editor, and the response preview. 1:18 The backend editor contains the code responsible for 1:24 receiving the GraphicQL in building a response. 1:27 In this course, we'll be using pre-built Launchpad templates, so 1:30 you won't need to make any changes in this pane. 1:34 However, this pane will contain the schema for each lesson. 1:37 We'll use the schema to identify which fields are queryable for 1:41 a given end point. 1:45 The query editor is where we'll spending most of our time. 1:47 This is the interface we'll use for writing queries and 1:51 specifying the fields we want returned in our response. 1:54 As you might have guessed, the response preview 1:58 is where we can see the response that is returned by the backend. 2:00 If a query is unsuccessful, this is also where we'll see errors. 2:04
