@appendNode / @prependNode

@appendNode and @prependNode will automatically add data from a mutation result to a connection on the cache.

The @appendNode will add an element to the bottom of a list, and the @prependNode will add it to the top.

@appendNode

mutation AddBar($input: AddBarInput!, $connections: [String!]!) {
  addBar(input: $input) {
    bar @appendNode(connections: $connections) {
      name
    }
  }
}

@prependNode

mutation AddBar($input: AddBarInput!, $connections: [String!]!) {
  addBar(input: $input) {
    bar @appendNode(connections: $connections) {
      name
    }
  }
}
