flipt VS go-grpc-middleware

We at https://flipt.io are putting on a buy vs build webinar in a couple of weeks to discuss this very thing as it's a common question that engineering teams seem to have.

If you're interested in attending its taking place on LinkedIn on April 17: https://www.linkedin.com/events/buildvs-buy-pickingafeaturef...

We're currently evaluating OPA for adding RBAC to our open-source application [0]. We plan on using the Go API [1] and doing the policy eval directly in our app since our app is also written in Go.

The thinking is we'll have some basic built-in policies (like admins can do X, editors can do Y, etc) but also allow users to configure their own policies if they want by writing rego and loading their policy rules at startup time (via config). We'd document the inputs that we pass to the evaluation call such as request headers, IP, role, etc.

I'm curious if anyone has ever tried something like this or similar?

At Flipt, we continually discuss technologies that can bring change to the industry. In this article, we delve into cutting-edge top trends and tools that can redefine DevOps and platform engineering this year.

In this article, I will share the DevOps tools that we've used at Flipt and in previous roles (such as at InfluxDB). These tools are relevant for any modern software project.

But after onboarding 50+ contributors to Flipt, I realized there are ways to make starts easy for newbies.

In this article, I will share the effort-based issue labeling system we use at Flipt to deal with this problem.

Flipt has reached 3k GitHub stars ⭐ this week.

In this article, I’m sharing 3 GitHub Actions we use at Flipt that saved us more than 500 developer hours.

In this article, I’ll share 3 tools we use at Flipt to maintain high code quality and ship features reliably.

Hello, Those interviews are even crazy for internship. Anyway 1. Try to find a simple CRUD example online. You can check [this](https://tutorialedge.net/golang/go-grpc-beginners-tutorial/) 2. For logging you can check [go-grpc-middleware](https://github.com/grpc-ecosystem/go-grpc-middleware) 3. You can grpc-gateway in case they want some REST endpoints too 4. Use base62 to encode your url. So at least 2 columns in your table **shortenedUrl** and **url** 5. For such a project no need to use an ORM ( it's not advised anyway ). Implement 2 functions, one to insert into the db and the other one to read from the db. Remember to use transaction though 5. For unit tests go with the standard library and mock the 2 functions ( erroneous and valid cases )

Supported middlewares by gRPC framework.

I do some basic validation at the server layer using a GRPC interceptor.

Example auth middleware: https://github.com/grpc-ecosystem/go-grpc-middleware/blob/master/auth/examples_test.go

And initialize our gRPC service, here i used gRPC Middleware repository for unary interceptors:

I found this is very good gRPC Middleware repository, but we easy can create our own, for example logger interceptor:
