pongo2 VS openapi-generator

I've used https://github.com/flosch/pongo2 since it feels more dev friendly (like almost every other framework I've used). Check out https://github.com/avelino/awesome-go#template-engines for some others.

Doesn’t it bother your that your templates aren’t really valid HTML? Because of the way html/template works, one isn’t really able to implement template inheritance properly. So you end up with opening and closing tags scattered around multiple files? You might want to look at Pongo2, which implements most of Django’s templating syntax (incl. inheritance) and is pretty stable: https://github.com/flosch/pongo2

At least template-wise, I've developed pongo2 mimicking Django's template engine which I use myself for various projects. For the rest I usually stick with the standard library (net/http), golang-jwt, the Gorilla toolkit (note that it's been archived recently) and some software architecture patterns for middlewares, database abstraction, etc.

pongo2 is a community-built template engine with syntax inspired by Django-syntax. It is built by the community for Go. It is very popular today, with more than 2K stars on GitHub.

Django uses Jinja templating engine. Something similar is available at https://github.com/flosch/pongo2 Now you just have to pick which router you want and which ORM or not-ORM.

Yes, Go templating is quite hard. There was a feature request[1] to implement the Django/Jinja2-like Pongo2 template engine[2], but got rejected because it would have been a too big change.

Yes, there is pongo2 [0] and my runner (basically a small Go software that runs the template engine) pongo2-runner [1].

I'm not the author of the library (pongo2), but I'm using pongo2-runner to dynamically create config files out of environment variables, with custom logic. Super recommended.

Disclaimer: We're an early adopter of Stainless at Mux.

I've spent more of my time than I'd like to admit managing both OpenAPi spec files [1] and fighting with openapi-generator [2] than any sane person should have to. While it's great having the freedom to change the templates an thus generated SDKs you get with using that sort of approach, it's also super time consuming, and when you have a lot of SDKs (we have 6 generated SDKs), in my experience it needs someone devoted to managing the process, staying up with template changes etc.

Excited to see more SDK languages come to Stainless!

As a result, the following specification can be used to generate clients in a number of different languages via OpenAPI Generator.

Of course you can compile the server from source if you have Go and the OpenAPI generator JAR (https://github.com/OpenAPITools/openapi-generator?tab=readme...)

Follow these steps : https://github.com/c100k/rebootx-on-prem/blob/master/.github...

And then :

(cd ./impl/http-server-go && GOARCH=amd64 GOOS=openbsd go build -o /app/rebootx-on-prem-http-server-go-openbsd-amd64 -v)

By adapting the arch if needed. Not tested, but it should work.

TL;DR: Start generating your HTTP clients and all the DTOs of the requests and responses automatically from your API, using openapi-generator instead of writing your own.

As an alternative, you can also use the official OpenAPI Generator, which is a more generic tool supporting a wide range of languages and frameworks.

I trialed generating SDKs using the OpenAPI Generator package, which was largely unsatisfactory.

If Swagger/OpenAPI is available, save yourself a lot of trouble and generate the client using OpenAPI Generator. If not, use a library like RestEase to make it significantly easier to create the client.

For a run of the mill REST API you should generate OpenAPI (Swagger) info for the API using a library like NSwag or Swashbuckle. You'd want to do this no matter what because it's documentation for the API, but the bonus is that you can use it with tools like OpenAPI Generator to create API client code and models in a variety of languages. You certainly can create an API client library manually, it would entail having a nuget package with a class library that contains the models and client code for calling the endpoints (which I'd create using a lib such as RestEase unless you just enjoy writing boilerplate code by hand). However 95% of the time it simply isn't worth creating your own lib when OpenAPI is available because once you've done it a time or two it takes less than 5 min to run the generator and create (or update) a lib.

Then you can use oapi-codegen or openapi-generator to generate the Go (or other language) SDK for it.
