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.

Have you used generics?
I made a package like that: https://github.com/carlmjohnson/be. It’s probably my most frequent use of generics.

alecthomas/assert: A minimalist type-safe drop-in replacement for testify/require
I spent the last week working on one of these: https://github.com/carlmjohnson/be. Some initial thoughts I have are that the error messages basically don’t matter because if the test fails you’re going to dig into the line where the failure happens anyway.

requests

- requests v0.23.4 with XML support

The Go libraries that never failed us: 22 libraries you need to know
https://blog.carlmjohnson.net/post/2021/requests-golang-http-client/ talks about why that’s the API. To be honest, I think a lot of people have an irrational fear of mutability. If you want to make a clone, use .Clone(). If not then don’t. But if you don’t like mutability, you’re going to dislike using the Go standard library, which uses mutable package variables all over the place.

Too many returns?
Yeah, tons of boilerplate. See https://blog.carlmjohnson.net/post/2021/requests-golang-http-client/

How I write offline API tests in Go
Yeah, I made a simple response recorder inspired by VCR. VCR is a little more complex than I need but the basic approach is great.
- Libraries you use most of your projects?
-
json response data from curl tool is different than http.Get method.
The native Go HTTP library is very capable, but it is extremely verbose. At the risk of introducing more complexity, I suggest using https://github.com/carlmjohnson/requests just so you don’t have to deal with checking all the errors and making the status code is correct.

How GoLang Generics Empower Concise API: HTML Table Extraction Case Study
What the other commenter said but also read this: https://blog.carlmjohnson.net/post/2021/requests-golang-http-client/ It talks about the need for clients and contexts throughout.

go-vcr v3 has been released
VCR is a great project, and because it uses the standard Go http.RoundTripper interface, you can use it with other projects!
