What problem does GraphQL want to solve?

Problems with REST:

• When things start to get super nested
  • If a user has a company_name and a position_name
  • Schema database would need to JOIN on those tables
    • /users/23/companies... too many http requests if you wanna get all your friends companies
    • /users/23/friends/companies... ? too customized
    • /users/23/friends_with_companies... not RESTful
  • Also we only care about on that request is company name
• Difficult to decide on a URL schema
• Can be making too many HTTP Requests
• Easy to overserve data

What is GraphQL?

• A query language that allows data to be queried using a graph data structure

Lokka vs. Apollo vs. Relay

• Lokka: Super simple. Basic queries, mutations, some simple caching.
• Apollo: Produced by same guys as Meteor JS. Good balance between features and complexity
• Relay: Amazing performance for modal. By far the most complex.
