graphql-server | Example GraphQL server with Mongoose and Node.js | GraphQL library

Use @Info decorator to retrieve GraphQLResolveInfo value as the parameter.

Spent a few days, and found out the root cause. It is neither CORS nor authentication issue.

According to https://docs.aws.amazon.com/apigateway/latest/developerguide/amazon-api-gateway-using-stage-variables.html, it is expected to see "Missing Authentication Token" because I shall access to child resource instead of the endpoint itself. The child resource here is "******.execute-api.us-east-1.amazonaws.com/dev/graphql".

The Invoke URL link points to the root resource of the API in its beta stage. Navigating to the URL by choosing the link calls the beta stage GET method on the root resource. If methods are defined on child resources and not on the root resource itself, choosing the Invoke URL link returns a {"message":"Missing Authentication Token"} error response. In this case, you must append the name of a specific child resource to the Invoke URL link.

For why it failed to access "******.execute-api.us-east-1.amazonaws.com/dev/graphql", I found that error by checking CloudWatch logs. It is a great tool for debug.

context: A value to pass as the context to the graphql() function. If context is not provided, the request object is passed as the context.

This means you can passe any value to context.

In this tutorial he provided a function, so it make sens to call context() in the resolvers. But you are passing an object, you need to adapt your code. Try this

Yes, if you have access to the GraphQLSchema object used by your GraphQL server, then the simplest approach is to just use the graphql function exported by the graphql module. Note that you should await the returned Promise to access the result:

The UploadLink is just a drop-in replacement for HttpLink. There's no reason you shouldn't be able to use it. There's a demo KeystoneJS app here that shows the Apollo Client configuration, including using createUploadLink.

Actual usage of the mutation with the Upload scalar is shown here.

Looking at the source code, you should be able to use a custom image handler and call blob on the provided blobInfo object. Something like this:

Thanks to the fantastic work by James Hegedus, this is possible. Check out https://github.com/jthegedus/blog-code/tree/master/gcp-functions-graphql for the solution.

I'm still not 100% sure what exactly happened to the "client mutation identifier," but having done some research, it appears to have been a requirement in previous versions of Relay. This PR apparently removed the requirement by replacing it with some other mechanism, but it's not clear to me what that other mechanism does. I left a comment requesting more clarification around the documentation, which appears to be out of date.

At any rate, the client mutation identifier appears to have been related to some assumptions about mutation idempotency in Facebook's implementation of GraphQL.

I solve above mentioned problem.I exempt my Graphql endpoint from CSRF protection by wrapping the GraphQLView with the csrf_exempt decorator in urls.py file in django project, just same as this (see the source ):

If the Hasura database requires that exact connection string format, you can use it. However, you cannot use Cloud Run's Cloud SQL support. You will need to whitelist the entire Internet so that your Cloud Run instance can connect. Cloud Run does not publish a CIDR block of addresses. This method is not recommended.

The Unix Socket method is for Cloud SQL Proxy that Cloud Run supports. This is the connection method used internally to your container when Cloud Run is managing the connection to Cloud SQL. Note, for this method IP based hostnames are not supported in your client to connect to Cloud Run's Cloud SQL Proxy.

You can embed the Cloud SQL Proxy directly in your container. Then you can use 127.0.0.1 as the hostname part for the connection string. This will require that you create a shell script as your Cloud Run entrypoint to launch both the proxy and your application. Based on your scenario, I recommend this method.

The Cloud SQL Proxy is written in Go and the source code is published.

If you choose to embed the proxy, don't forget to add the Cloud SQL Client role to the Cloud Run service account.
