问题 This question already has answers here : ECMAScript 6 arrow function that returns an object (6 answers) Closed 3 years ago . I've been working through some Graph QL/React/Relay examples and I ran into some strange syntax. When defining the fields in Graph QL Objects the following syntax is used: const xType = new GraphQLObjectType({ name: 'X', description: 'A made up type for example.', fields: () => ({ field: {/*etc.*/} }) }); From what I gather this is just defining an anonymous function

问题 Title mostly says it all: I'm building a react / relay application which will allow the user to dynamically create charts at runtime displaying their various income streams over a specified time range. One feature of this chart is the ability of the user to specify the sampling interval of each income stream (e.g. YEAR , QUARTER , MONTH , WEEK , etc.) as a parameter of each stream. These values are defined in the schema as a GraphQLInputObjectType instance as follows: enum

问题 I'm creating a voting applications with polls that can be voted. I'm currently stuck on voting for a poll (essentially, creating a vote). My schema: (Long story short: polls are accessible from the main store, but the viewer's polls and votes can be accessed directly by him (as fields). votes also are accessible from the min store, but the poll's votes can be accessed also directly by it. query { store { polls { //poll connection edges { node { //poll votes { //vote connection ... } } } }

问题 I have working tinySQL GraphQL server running at 127.0.0.1:3000. I would like to create any working Relay client for it.

How to update Relay store without pushing to server

问题 I have a form in my React/Relay app that I am using to modify some fields. I don't want to send a server update every time a new letter is typed into an input.

Having read through most of the Relay docs it seems to me that I have to basically copy the Relay state either to the local state of my form or to some other Flux store, deal with changing it in there, and then commit it into Relay. That seems
