AGENDA

REST is cool, but...

How many queries do we need to render this view? 

Over-fetching

Hard to design "proper" api

Documentation hell

Data fetching is a problem

What is GraphQL?

A query language for your API

Features I wanted as UI developer

  • Fast data queries with all&only needed data
  • Data caching, to avoid refetching
  • Allow to work offline
  • Specify queries, parses data
  • Easy to paginate
  • Execute mutations, with cache and pagination

GraphQL server isn't that easy...

Tips & tricks

  • Use limits on bigger amount of data
  • Define schema first
  • Read carefully full specification, it may help
