GraphQL Cheat Sheet

Overview

• An alternative approach to RESTful APIs
• Clients issue queries/mutations to read and update data
• Clients can fetch only the entity fields that are required
• GraphQL query syntax can express complex entity relations => nested objects
• Mitigates the explosion of RESTful endpoints in scenarios where many different representations of an entity are needed
• Graphiql is a query execution UI, also provides good documentation
