WordCamp 2019 - GraphQL in WordPress

https://ebeldev.github.io/graphql-in-wordpress/
(use down arrow too)

travel analogy
talking about REST API

• URL/wp-json/wp/v2/posts etc
• his point here is how many calls per endpoint REST takes
• risks:
  • over-fetching - one endpoint gives you a lot of data you do not need
  • under-fetching - one endpoint may not give you all you need

GraphQL - invented by Facebook basically

types of operation

• query
• mutation
• subscription

concepts:
nodes and edges
looks like data category ("posts") is the edge, and specific items (the actual posts) are the nodes

can define fragments

Software

WordExpress
WP-GraphQL -- https://www.wpgraphql.com/ the best one

• can be extended through hooks to add data to query or do other mutations
• not on version one yet, but still production ready

Frontend - Relay or Apollo (React though)

GraphiQL is the Postman for GraphQL
like/with https://playground.wpgraphql.com

GraphQL is always POST method
Gutenburg doesn't work with GraphQL or REST because it sucks. Adds a lot of code that the front end strips out, but the APIs won't

Server side resolvers being a core issue
