Timestamp": "12/12/2015 - 15:25" } ] } } [ 49 ] The Query Language We have the same data here but with slightly different property names. Instead of processing the original response on the client side and copying it to a new structure suitable for our UI, we can use GraphQL field aliases to instruct the GraphQL server to respond with its data using different property names. We can use aliases on any field to customize its appearance in the response: query ArticleResponses { post: article(articleId: 42) { responses: comments { responseId: commentId formattedBody timestamp } } } The ArticleResponses query is asking for the same data but it uses aliases to rename some fields in the response.

It's no longer just numbers for pagination. One problem with this model is that there is no way to figure out whether there is more information to fetch or we just fetched the last available slice of comments. This means we need to do an extra request that returns an empty slice to conclude that we were on the last page. The connection model: Relay extends the after/first model with a structure of edges and nodes, so that we can store extra information and metadata about the paginated data. The actual data is represented as nodes within edges.

The resolve() function is what the graphql library executes when it tries to answer queries asking about that field. For our simple example, we resolve that hello field with the string world. exports = mySchema; I am going to maintain a GitHub repository for this book.
