            Cant delete item from sqlite by qraphql mutation
            Asked 2022-Mar-27 at 23:21

            I'm learning to write apollo server by following a graphql tutorial but when I try to write a delete mutation and use it in the GraphQL Playground, I get null after executing, and if I check data in the Prisma studio there is no change

            mutation delete and server response

            I'm sure that there are many items for deleting also with current id which I used for delete this is my code

            I gat it. Instead data use where. Prisma supports filtering with where query option.

            Try to use require(“module”) or if that's the way you doing it, you sould try import("module"). Maybe this will help.



            Send data between GraphQL Node.js server and React in Nx
            Asked 2021-Sep-30 at 11:38

            I setup two projects, Node.js and React in Nx monorepo. I would like to use GraphQL for communication. Projects I'm running with command nx serve api(Node.js) and nx serve totodile (React). Problem is that React cannot access data from /graphql endpoint.

            React is running on http://localhost:4200/.
            Node.js is running on http://localhost:3333/.

            Node.js part

            According to GraphQL instructions for Node.js I run Node.js server. I have created two endpoints /api and /graphql.



            Answered 2021-Sep-30 at 11:38

            To fix issue there was 2 steps to do:

            1. In React I should fetch from endpoint with port fetch('http://localhost:3333/graphql',(...))
            2. In Node.js there is need to use cors library



            graphql node api: how can I define a field as optional?
            Asked 2021-Aug-08 at 09:39

            GraphQL allows you to specify whether a field is to be optional or not (add !)

            Using the Node API, I cannot find that option.

            What is the difference between gql and buildSchema?
            Asked 2021-May-08 at 08:36

            What is the difference between graphql-js buildSchema and the apollo-server gql? They appear to do a very similar job.



            Answered 2021-May-08 at 08:36

            Firstly note, apollo-server's gql is actually a re-export from graphql-tag. graphql-tag is a ~150 line package who's default and pretty much only useful export is gql.

            Quick bit of background: the graphql-js package provides an official reference implementation of GraphQL in Javascript. It provides two important things basically:

            1. The graphql function, which will process any GraphQL query against a GraphQLSchema object (the GraphQLSchema object is how graphql-js represents your parsed schema).
            2. A bunch of utility functions and types for building and validating the GraphQLSchema objects used by the graphql function from strings.

            Now, this is the part that ultimately confused me: in graphql-js, taking a string and turning it into a GraphQLSchema object is a two step process:

            • Step 1: String -> AST (done by the parse function).
            • Step 2: AST -> GraphQLSchema (done by the buildASTSchema function).

            It is like this is because the AST (Abstract Syntax Tree) is useful to a bunch of other tools which aren't even necessarily aware of GraphQL (for example see, where as the GraphQLSchema is only meaningful to graphql-js and related softwares.

            graphql-js exposes the functions for doing both steps and these are reused by downstream implementors (like Apollo). buildSchema is just a convenience wrapper to combine these two steps. It's literally this:



            GraphQL resolvers - when to make resolver functions async or not?
            Asked 2021-Apr-30 at 09:51

            I completed this tutorial on making a graphql-node backend server built on Prisma2 and GraphQL. The tutorial doesn't explain why it writes some Resolver functions async and some not.

            I thought that the async was added to functions that interacted with the database, but you can see this resolver gets data from the database but doesn't use async. But in this resolver it does use async.

            Can somebody please explain why there is this seemingly arbitrary usage of async? When and why I should use it? Thanks in advance.



            Answered 2021-Apr-30 at 09:51

            The first thing you should do is read up on Promises. Promises are a way in JavaScript to encapsulate computations that are still ongoing. This is usually the case when you talk to an external service like a database or the operating system. They have been replacing callback style APIs.

            In GraphQL a resolver can either return a value or a Promise that resolves to a value. This means, you can freely choose returning a value or a Promise, but if you call a database function like Prisma, you will get a Promise back, so you are kind of forced to stay "in Promise land", as there is no way to turn a Promise into a value. You can only chain functions, that should be executed with the value "in the future" (with then).

            The last concept to understand is async/await. These async syntax is an addition to JavaScript syntax, that makes working with Promises easier. With await, you can stop the execution of a function until a value in a Promise arrives. Now, this looks like you are turning a Promise back into a value, but in reality, you function implicitly returns a Promise. For the VM to know about this, you have to state, that a function might use async by adding the keyword await in front of the function.

            So when do you use async for a resolver? You could do it all the time, and the code would be correct. But doing it, even when you don't need to (e.g. you are not talking to a service) might have some performance implications. So it's better to only do it, if you really want to use the await keyword somewhere. I hope this can get you started with the concepts above, there is really a lot to learn. Maybe just go with your intuition and TypeScript errors until you deeply understand what is going on.



            HowToGraphQL - Chapter 6 Authentication - Why is postedBy() invoked?
            Asked 2021-Apr-03 at 11:14

            I hope I can get clarity when asking this question since GraphQL is a fairly obscure concept and there aren't that many answers online.

            In the tutorial ( in the #Resolving relations section near the middle of the page there's this code:



            Answered 2021-Apr-03 at 11:14

            This part is not strictly related to auth [reasons] ... creating post mutation will work without that. But:

            • post mutation creates an [Link] entry with a relation (to User in prisma schema meaning docs );
            • postedBy is a virtual field - 'Relation fields define connections between models at the Prisma level and do not exist in the database. ';
            • post mutation returns a Post type - then 'asked' return object can contain postedBy field (and its User object/type subfield[-s]);
            • when postedBy field is queried (as part of mutation result tree), it (related User object/type - graphql context) must be resolved using function postedBy(parent, args, context);

            In resolver body we're using/working with "Prisma client" - ORM lib, then:



            Why maintain two-way pointers in data design?
            Asked 2021-Mar-19 at 06:58

            Assume I have the following schema:




            Answered 2021-Mar-19 at 06:58

            I think it depends on your use cases. Says you only maintain 1-way pointer that keeps books array in author document, if you have a use case that requires searching for author by a certain book, you will need to do a full collection scan of author collection to find all matches. So without much knowledge of your actual scenario, it could be hard for us to comment on the necessity of 2 way pointer in your database.

            This document is a good piece for your reading.
