Practical GraphQL - Become a GraphQL Ninja - Creating the application shell

This video tutorial guides viewers through setting up a basic Express application with GraphQL features using Apollo Server. It covers the installation of necessary dependencies, including Node.js, Express, and Apollo Server, and provides an overview of the Apollo Server's website and documentation. The tutorial then demonstrates how to create a GraphQL server by defining type definitions and resolvers, and integrating Apollo Server as middleware in an Express application. The video concludes with a discussion on potential errors and the next steps for populating type definitions and resolvers.

What is the first step to set up the basic structure of an Express app?

• Install Node.js

• Create a database

• Write the main application code

• Set up a server

Which package is used to create a GraphQL service in the discussed setup?

• React

• Vue.js

• Apollo Server

• Express

What is the purpose of the 'abgs' file in the Express app setup?

• To handle API requests

• To manage user authentication

• To place all the initial setup code

• To store database configurations

What are the two main components required by GraphQL as mentioned in the video?

• Resolvers and Queries

• Type Definitions and Resolvers

• Schemas and Mutations

• Endpoints and Handlers

Which method is used to integrate Apollo Server with Express?

• applyMiddleware

• useServer

• attachMiddleware

• connectServer

What is the role of the 'applyMiddleware' method in the setup?

• To configure GraphQL queries

• To start the Express server

• To apply middleware functions in Express

• To connect Apollo Server with a database

What error might occur if type definitions and resolvers are not set?

• Server not found

• Apollo Server requires an existing schema
