Because the mutation has one consistent name and graphql will not allow to have the same operation multiple times in one query. When it comes to GraphQL, this leaves many asking “well, how can I do this with my mutations?” Imagine the same example with your GraphQL API – you submit two mutations in a single request but you want everything to roll back if one of them fails. Multiple fields in mutations. I have explored Admin GraphQL, but at the moment i only found productUpdate mutation which will update only a single product or I am missing something here. Solved: Hi, I am looking a way by which i can update bulk update products using your Admin GraphQL. GraphQL can accept multiple mutations at a time, so it’s one request. Neither the products nor the author will have any reviews yet, so all we need is the names. Let’s go back to GraphQL Playground and execute the following to start a subscription: GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. While query fields are executed in parallel, mutation fields run in series, one after the other. Currently, there’s nothing in the spec about this. Welcome to another post on GraphQL Mutation Design. GraphQL query batching means sending multiple queries to the server in one request, which can have some pretty significant benefits: Reducing the total number of server roundtrips, which can incur significant overhead in HTTP 1.x. Looking A mutation can contain multiple fields, just like a query. Input types can't have fields that are other objects, only basic scalar types, list types, and other input types. It allows for static queries instead of using n fields to update n objects for example. If there's a single anonymous operation then the API could behave like it does now, if there's multiple operations, the options object has to be a map where each key has to be the name of the operations defined. GraphQL can do more than just query data. So for this to work Apollo would have to map the mutations into aliases and then even map the variables data into some unknown iterable form, which i highly doubt it does. A query language for your API. I am trying to figure out how to mutate a nested object with graphql mutations, if possible. Here, the mutations return a Message type, so that the client can get more information about the newly-modified Message in the same request as the request that mutates it.. How do you do it? GraphQL is elegantly simple, but simple comes at a cost. Unfortunately, once that object is returned, GraphQL is off to the next mutation request, unaware that there are further mutation operations to be performed in the request. Is there a way to bulk update products in one call. GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. ; It makes “transactions” easier: Our resolver for the mutation can decide to fail all updates if one of them fails. The Star Wars example we’re using provides one mutation example (adding a review) and one subscription example (getting notified when a review is added). The “problem” is that GraphQL executes a Nested mutation, returning an object with further mutation methods. I guess that the options object would need to be a map by operation name. Mutations and Subscriptions. This means that if we send two updateAuthor mutations in one request, the first is guaranteed to finish before the second begins.
