![]() Input objects just contain attributes and relationship with names directly matching Relationships are links to other entities in the graph. The schema for both kinds of objects are derived from the entity relationship graph (defined by the JPA data model).īoth contain a set of attributes and relationships. Input Objects which are used to supply input data to mutations.Query objects which are used to compose queries and mutations.GraphQL splits its schema into two kinds of objects: Note that it is possible to receive a 200 HTTP OK from Elide but also have errors in the query. The ‘data’ field contains the graphQL response object, and the ‘errors’ field (only present when they exist) contains one or more errors encountered when executing the query. variables - Contains a json object of key/value pairs where the keys map to variable names in the query and the values map to the variable values.operationName - Used if multiple operations are present in the same query.Namely, ever GraphQL query is wrapped in a JSON envelope object with one required attribute and two optional attributes: It follows the convention defined by GraphQL for serving over HTTP. JSON EnvelopeĮlide accepts GraphQL queries embedded in HTTP POST requests. ![]() Perform any combination of the above edits together so they can happen atomically in a single request.Įlide offers an opinionated GraphQL API that addresses exactly how to do these things in a uniform way across your entire data model graph.Reference a newly created object inside other mutation operations.Change the composition of a relationship to something different.Differentiate between deleting an object vs disassociating an object from a relationship (but not deleting it).Create a set of related, composite objects (a subgraph) and connect it to an existing, persisted graph.Create a new object and add it to an existing collection in the same operation.In API expression, but also little direction for best practices for common mutation operations. The specification provides great flexibility GraphQL is a language specification published by Facebook for constructing graph APIs. ![]()
