API Documentation

1. Querying exactly what you need, by passing food id in query variables section

Query

query getSingleFood($foodID: Int!) {
  food(id: $foodID) {
    name
    carbs
    proteins
    fats
  }
}

Query variables

{ 
    "foodID":1
}

2. Query with fragments by assigning aliases. This helps to get multiple query results in a single go

Query

query getFoodWithFragments($foodID1: Int!, $foodID2: Int!) {
      food1: food(id: $foodID1) {
             ...foodFields
      },
      food2: food(id: $foodID2) {
            ...foodFields
      } 
}

fragment foodFields on Food {
  meal
  carbs
  proteins
  fats
}

Query variables

{ 
    "foodID1":1,
    "foodID2":2
}

3. Using mutations to update the meal of the food

Query

mutation updateFoodMeal($id: Int!, $meal: String!) {
  updateFoodMeal(id: $id, meal: $meal) {
    ... foodFields
  }
}

fragment foodFields on Food {
  meal
  carbs
  proteins
  fats
}

Query variables

{
  "id": 1,
  "meal": "pre-lunch"
}
