CORS Nightmare, please HELP
And, you could find some cors knowledge on https://github.com/rs/cors

Handling CORS in Nginx as a reverse proxy
We have REST services that need to be used with the browser, We configured these HTTP Golang services to handle CORS using cors package.

Confusion around setting headers and statusOK
Give it a try to this library https://github.com/rs/cors and put the middleware in your router.

help about CORS
I'm learning Go, so I made a pretty simple rest api, now I want to use it in a React frontent, I decided to use the github.com/rs/cors library, using the default configuration of this library everything works fine, but when I add "AllowedOrigins":

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.

IBM to Acquire HashiCorp, Inc
My experience of Golang is that dependency injection doesn't really have much benefit. It felt like a square peg in a round hole exercise when my team considered it. The team was almost exclusively Java/Typescript Devs so it was something that we thought we needed but I don't believe we actually missed once we decided to not pursue it.
If you are looking at OpenAPI in Golang I can recommend having a look at https://goa.design/. It's a DSL that generates OpenAPI specs and provides an implementation of the endpoints described. Can also generate gRPC from the same definitions.
We found this removed the need to write almost all of the API layer and a lot of the associated validation. We found the generated code including the server element to be production ready from the get go.

Microservices communication
See https://goa.design/. It automates all the comms stuff, so you just write: 1) a design file showing your functions, 2) an implantation of those functions, and 3) a very generic "main.go" (basically the same for all your services) that decides "how is this exposed over gRPC or REST or other comms?". The rest of the code is generated.

Create Production-Ready SDKs with Goa
Perhaps the easiest way to find out how to do something (especially when using Meta) is to search the test cases when you have cloned the source code.

Which is the best framework to create web apps with go?
If you really need a framework, you can take a look at Echo or, for a contract-first approach, https://goa.design/

OpenAPI v4 Proposal
Few folks in here are (rightly) frustrated with the code generation story and broader tooling support around the OpenAPI standard. I've found a few alternative approaches quite nice to work with:
- Use a DSL to describe your service and have it spit out the OpenAPI spec as well as server stubs. In other words, I wouldn't bother writing OpenAPI directly - it's an artifact that is generated at build time. As a Go user, I quite like Goa (https://goa.design/) but there are others shared in here like TypeSpec.
- There are situations where sticking a backend-for-frontend (BFF) in front of APIs can yield great productivity boosts. For example, in the past we built a thin GraphQL proxy that calls out to a poorly structured REST API. Integrating with that was much more convenient. Most recently, I've been playing with a BFF built with tRPC (https://trpc.io/) which calls out to a REST API. It seemed to provide an even better experience if you use TypeScript on the front-end and in the BFF. It does not have a codegen step and I was really pleased with how fast I could iterate with it - granted it was a toy project.

Beginner-friendly API made with Go following hexagonal architecture.
One of the biggest issues I see is that you are using the same models for API as you are for the database. That wouldn’t fly in a real work system. And even though your doing simple CRUD I would introduce another layer for business logic. You should never have the Controller calling you database code directly. It never “stays” that simplistic. One of the easiest ways to deal with this is to use Goa. https://goa.design/ It takes care of generating your API models and it creates the Interfaces to implement for your business logic. Furthermore it creates OpenAPI documentation (something missing in this design that is a must for commercial development).

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.

Do you really need microservices?
Goa and Kong are some of the best frameworks to develop and deploy microservices. They provide features such as out-of-the-box support for service discovery, routing and authentication that make it easier to build more complex applications. There are also newer architectural frameworks with less steep learning curves like GPTDeploy that lets you build and deploy microservices with a single command.

Dumb question about APIs, Mux and Go
Or the one we use at work: https://goa.design/ Goa does a lot more and maybe more than you need. We use it as it can generate both REST and gRPC as well as API models and OpenAPI documentation (JSON and YAML).
