问题 Is there any way of enabling special characters in GraphQL schema (e.g., / , : , @ in the field names)? And if there isn't (which I suspect is the case) do you have an idea what would be relatively easiest way to modify the node.js code (https://github.com/graphql/graphql-js) to achieve such functionality? 回答1: I would recommend against doing in this. graphql-js follows the grammatical form stated in the graphql specification. Such a change would be a break away from the specification and

问题 I've been reading through the graphQL docs and found that they've explained the implementation of the graphql server in 2 ways: one using graphql-yoga which is a fully featured graphql server and another one is using graphql, express-graphql and express. In both cases, we pass the schema and resolver functions while creating the server instance. But the implementation of resolver function differs. While using graphql-yoga, the resolver function is provided with 4 arguments which contains

问题 How do I represent a field that could be either a simple ObjectId string or a populated Object Entity?

问题 I am new to GraphQL. Started developing an GraphQL app to pull the data from oracle database. It is very simple application. The query responds with the resultset and can be seen results in console.log ; however, it doesn't come to the graphql window (response/resolver window). It throws the error Cannot return null for non User.email I tried the promise in the oracle connection. Not sure, why it is not showing the data in GraphQL. UserType.js module.exports = new GraphQLObjectType({ name:

问题 EDIT added my solution as an answer ORIGINAL QUESTION i believe this issue has to do with circular dependencies. i spent the better half of last night and today trying everything i could find online but nothing seems to work. what i have tried: convert the fields prop to a function that returns a field object convert the relating fields (within the fields prop) into functions that return the type combining the two approaches above finally ending with require statements in place of the fields
