Who moved my error codes? Adding error types to your GoLang GraphQL Server
GraphQL’s spec, as it turns out, does not specify how servers should handle internal errors at all, leaving it entirely to the choice of the frameworks’ creators. Take for example our GoLang GraphQL framework of choice - gqlgen. It makes no distinction between intentional and unexpected errors: all errors are returned as-is to the client within the error message. Internal errors, which often contain sensitive information like network details and internal URIs, would leak to clients easily if not caught manually by the programmer.

“Go is hard to justify unless at massive scale”
Better look into this one: https://github.com/99designs/gqlgen for GraphQL powered by Go. It's spec first approach and requires the least boilerplate code to write. It also incorporates seamlessly with Apollo Federation.

Go with PHP
I left PHP for Go.
- with http://sqlc.dev I don't have to write ORM or model code anymore.
- with http://goa.design I can have well-documented API's that any team can generate a client for in any language. It also generates the HTTP JSON and gRPC servers for me so I can focus on my logic.
- with https://github.com/99designs/gqlgen I can define GraphQL revolvers that play well with sqlc (any RDBMS) or I can use a key-value store.
- speaking of key-value stores, Go allows them to be embedded! Even SQLite now has the https://litestream.io/ project to make it super simple to use a durable, always backed-up SQLite database even in a serverless context.
Go is faster, uses less memory, and has really-well designed stdlib without all the bugs I used to face trying to use the PHP stdlib.

Libraries you use most of your projects?
In addition to the ones you mentioned, I also always use: + sqlc - Compile SQL to type-safe code + gqlgen - generate GraphQL server from schema + oapi-codegen - Go client and server boilerplate from OpenAPI 3 specifications + pester - Go http calls with retries and backoff + backoff - exponential backoff algorithm in Go

Ent: An Entity Framework for Go
I have no experience in Django but in Ent with GraphQL.
Ent is not a full-featured web framework so you need to implement many of features by your own or use other libraries (e.g. http server and session management).
If you are only looking for ORM + GraphQL then I highly recommend trying Entgql, an Ent extension for GraphQL with Gqlgen library [1]. Once you define an ORM schema, it will generate GraphQL Query for Relay server. Still you need to implement GraphQL Mutations by your own but at least it will create Input types for you (both for Create/Update).

Best packages?
gqlgen for GraphQL services. It's well documented and maintained.

Decent examples querying models from Postgres
For me sqlc work wonders. If you are developing a user facing api and are fine to go with graphql, with gqlgen you can even autobind (search the page for @goModel) the models that sqlc generates from your queries. A glorious match

Best CORS library for small web apps (rs/cors vs go-chi/cors)
Now, for CORS I am currently using the rs/cors package, but noticed that it has the whole gin-gonic/gin library as a dependency. I found gin-chi/cors which has no dependency at all but seems to do the same thing.

Why to use the net http package for building web app
The only thing missing is a more dynamic router, and this is where we have the usefulness of being able to pick a small, focused library for it (e.g. gorilla/mux). The base package is also highly interoperable with middleware (e.g. rs/cors for managing CORS headers), so in most cases it is easier to just pick out the features you want and compose them on top of net/http (or write them yourself), rather than find a framework that does it all.

Golang with React Admin Issue
Hello, I am new to go and I have created a mux server using gorm. I am using the cors go library to enable cors. I have added a vue/nuxt frontend and all my routes are working fine. However, I have been trying to integrate react-admin and I am getting cors issues only on PUT requests. Could someone help me figure out what the issue is. Thanks.

I had a Go, CORS and Single Page App Ordeal So You Don’t Have To | Integration Junction
It might be a function of the fact that the project had a hand crafted main rather than using the generated one, but when I hit this for adding CORS to a go-swagger project we used a handler generated by rs/cors as middleware - it (and a bunch of other middleware) wrapped the generated server's handler as go-swagger uses one root handler.
