Introduction to GraphQL

Created by Facebook, a GraphQL server has four MAIN responsibilities:

1. Receive requests in GraphQL format (query and mutation)
2. Connect to DB and services
3. Validate requests
4. Return GraphQL responses (requested data and error messages)

Schema-Driven Development

The steps we’ll follow to build a GraphQL server, which revolves around schema definition will be:

1. Define your types and the queries and mutations for them
2. Implement functions called resolvers to handle these types and their fields
3. As new requirements arrive, go back to step 1 to update the schema and continue through the other steps

Try making a project in Django to understand GraphQL better.
