Graphql queries

Without Params

Some fields may be implied by the REST API path, so no params are required.

{
  name
  createdAt
}

With Params

Other times, you may need to use parameters in your query.

# https://tracking-system/projects/1/graphql
{
  tasks($name: String){
    status
    createdAt
  }
}

{"name": "clean bathroom"}

Fragments

TODO:

Example schema

• Select type-specific fields in heterogenous collections
• Concisely describe a group of fields, DRY out queries
• Concisely describe Recursive/Nested nodes

named fragments

{
  children {

    ...nodeFields
    children {

      ...nodeFields {
        children {

          ...nodeFields
        }
      }
    }
  }
}


fragment nodeFields on Node {
  id
  text
  colour
  background-colour
}

inline fragments

    vehicles {
      wheels               # select on both Car and Motorcycle
      passengers

      ... on Car {         # select on Car items only
