Description:

What is GraphQL

Think in graphs, not endpoints - by Lee Byron, GraphQL Co-Inventor.

- data query language for client-server communication for data fetching and manipulation
- support for server-side frameworks, client libraries
- reduces development efforts and network bandwidth

what you want is what you get

What are REST(ish) APIs

APIs that talk HTTP (verbs) which give structured access to resources

(examples)

Challenges and pain points with REST

- over or underfetching information
- querying nested information is a pain
(examples)

How GraphQL answers those challenges with examples

- single query to the server that includes concrete data requirements
    - get exactly what you need in the format how you need it
- strong schema and type system
    - smaller API dev cycles
    - validation
    - powerful introspection system
- allows querying nested information naturally
