Our great sponsors
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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).
- Why is gin so popular?
-
Does this project structure make sense?
I typically use Goa for my controller. It makes the API Controller, API models, and OpenAPI Documentation. Making the OpenAPI documentation can be a pain, so this really helps. https://goa.design/

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.

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
What are some alternatives?
Gin - Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.
