Add this code in server. I do see there are still the disadvantages of syncing systems though. If any data node has been updated since the last sync, any queries asking for those nodes or objects must be requeried.

It wraps your React app and places the client on the context, which allows you to access it from anywhere in your component tree. Launchpad takes care of the tiny details. Designed for debugging, developer tools, etc.

A complete introduction to Apollo, the GraphQL toolkit

The simplest way to get started with Apollo Client is by using Apollo Boost, our starter kit that configures your client for you with our recommended settings. Apollo Boost includes packages that we think are essential for building an Apollo app, like our in memory cache, local state management, and error handling. The only thing you need to get started is the endpoint for your. Now your client is ready to start fetching data. Remember to first import the gql function for parsing your query string into a query apollo client github. You should see a data property with rates attached, along with some other properties like loading and networkStatus. Connect your client to React To connect Apollo Client to React, you will need to use the ApolloProvider component exported from react-apollo. It wraps your React app and places the client on the context, which allows you to access it from anywhere in your component tree. Apollo Client tracks error and loading state for you, which will be reflected in the loading and error properties. Once the result of your query comes back, it will be attached to the data property. Try building more Query components and experimenting with the concepts you just learned. Configuration options Here are the options you can pass to the ApolloClient exported from apollo-boost. All of them are optional. To dynamically set fetchOptions, you can add them to the context of the operation with operation. Any options set here will take precedence over fetchOptions. If you would like to handle your errors differently, specify this function. This is useful if you would like to use the Apollo cache for local state management. This option can be used to indicate whether the user agent should send cookies with requests. The default value is InMemoryCache from apollo-cache-inmemory. Apollo client github option is quite useful for using a custom cache with apollo-cache-persist.

The function returns a promise that fulfills with your mutation result. Most of all, Apollo Client is built to be simple, small and flexible from the ground up. I think it would be really great if the different ways of implementing offline support with Apollo could be explained or sketched out in the documentation. You might be able to use something like this: The goal is that you can use some standard Redux offline library rather than needing something specifically for apollo, but I don't know if we have all of the necessary features for this. I don't understand Apollo very well at all. Any options set here will take precedence over fetchOptions. This option is quite useful for using a custom cache with apollo-cache-persist.
