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.

Seeking advice on implementing a tinyurl-like service using Go and gRPC.
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 )

[Question] Suggested way to update a database row using gRPC/PostgreSQL (pgx) ?
I do some basic validation at the server layer using a GRPC interceptor.

Go, RabbitMQ and gRPC Clean Architecture microservice 💫👋
And initialize our gRPC service, here i used gRPC Middleware repository for unary interceptors:

Go gRPC Clean architecture microservice with Prometheus, Grafana monitoring and Jaeger opentracing ⚡️
I found this is very good gRPC Middleware repository, but we easy can create our own, for example logger interceptor:

API validation in Gin: Ensuring Data Integrity in Your API
If you want to know all the available validation in Gin. Then you can look at this package because Gin uses this package under the hood. Package: https://github.com/go-playground/validator Specific-file: https://github.com/go-playground/validator/blob/master/baked_in.go#L73

Yet another validator 0.9.5
Now it has most of the Playground validator's common checks and a few own tricks.

Openapi server generation
In Go I've found this package - https://github.com/go-playground/validator. It seems popular in the community, but it is tag-based. It looks like if I wanted to use it - I would have to basically duplicate structs.

Validator in handler or domain
so I am working on a ecommerce api as a hobby project which is mostly inspired by wtf dial project I like to use validator package to remove boilerplate over my domain package for example take a look https://github.com/mortezadadgar/ecommerce-api/blob/b0bf43d042d62fdca1c2d097ec51b05bc539cef2/domain/users.go#L33 I have to option either add validate.Struct() to my domain which is suggested to avoid by author of wtf peoject or add it to handler which I doubt is a good idea as it's not in business logic of handler and makes unit testing harder

Request Validations in Go REST API
I use https://github.com/go-playground/validator, but honestly, I am not a fan. I just haven’t found anything better.

Tools besides Go for a newbie
IDE: use whatever make you productive. I personally use vscode. VCS: git, as golang communities use github heavily as base for many libraries. AFAIK Linter: use staticcheck for linting as it looks like mostly used linting tool in go, supported by many also. In Vscode it will be recommended once you install go plugin. Libraries/Framework: actually the standard libraries already included many things you need, decent enough for your day-to-day development cycles(e.g. `net/http`). But here are things for extra: - Struct fields validator: validator - Http server lib: chi router , httprouter , fasthttp (for non standard http implementations, but fast) - Web Framework: echo , gin , fiber , beego , etc - Http client lib: most already covered by stdlib(net/http), so you rarely need extra lib for this, but if you really need some are: resty - CLI: cobra - Config: godotenv , viper - DB Drivers: sqlx , postgre , sqlite , mysql - nosql: redis , mongodb , elasticsearch - ORM: gorm , entgo , sqlc(codegen) - JS Transpiler: gopherjs - GUI: fyne - grpc: grpc - logging: zerolog - test: testify , gomock , dockertest - and many others you can find here
