Recompose Apollo

a utility belt for higher-order components in apollo. Recompose utilities for react-apollo.

Higher-order components

withQueryData()

withQueryData(
  queryDocument: DocumentNode,
  optionsObject: { options: (props) => { variables } } | { options: Object }
): HigherOrderComponent

Same functionality as react-apollo graphql HOC, except the data prop or named data prop is flattened.

withQueryComponent()

withQueryComponent(
  queryDocument: DocumentNode,
  optionsObject: { options: (props) => { variables } } | { options: Object }
): Component

Return a query component given a GraphQL document and options. What's returned is a Component with a render child that has the data object from react-apollo, see below.

Query Components outlined: https://dev-blog.apollodata.com/query-components-with-apollo-ec603188c157

const CitiesQuery = withQueryComponent(cityQuery);
 
function Sample() {
  return (
    <CitiesQuery>
      {
        (data) => {
          return (
            <p> I am loading {data.loading ? 'Yes' : 'No'} </p>
          );
        }
      }
    </CitiesQuery>
  );
}

withFragment()

withFragment(
  fragmentDocument: DocumentNode,
  optionsObject: {
    name: string,
    getFragmentId: (props) => string,
  }
): HigherOrderComponent

After a query has been made with the graphql HOC, use this HOC to read fragments from the Apollo Client cache. Based on the options name, the fragment data will be returned to the component as props under that key or data.

withSubscribe()

withSubscribe(
  subscriptionDocument: DocumentNode,
  optionsObject: { options: (props) => { variables } }
): HigherOrderComponent

Create a GraphQL subscription that subscribes on componentDidMount. By providing a onResult prop to the Component, every time the subscription yields next, onResult will be called with the result of the subscription.

withLoadingState()

withLoadingState(
  Component: Function,
): HigherOrderComponent

Render a Component if the networkStatus from apollo-client is loading, otherwise return props for networkStatus:

• activelyRefetching
• passivelyRefetching
• fetchingMore

withErrorState()

withErrorState(
  Component: Function,
): HigherOrderComponent

Render a Component if the networkStatus from apollo-client is error.
