The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Visualizing Diffs The Myers difference algorithm
This made me think of a couple other interesting things:
1. you can change which algorithm is used in git diff as multiple are supported

2. Google has an edit graph implementation in Go in the cmp package

How do you do DB preparation in e2e tests?
Assertion libraries that people seem to love: - testify (my favorite) - go-cmp is a more barebones library - gotest.tools -- I have never used this but some swear by it

alecthomas/assert: A minimalist type-safe drop-in replacement for testify/require
it uses https://github.com/google/go-cmp instead of reflect.DeepEqual

What annoys you about Go?
When I use functional arguments, I either prefix all of the options with the same prefix or put them in a dedicated package (like cmpopts) to help the IDE.

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

Go Package for Equality: github.com/google/go-cmp
One thing to keep in mind about reflect.DeepEqual is because of the way it is implemented you could get positive results when the values are not actually the same, see this comment for reference.

JSON to Go Struct Converter
That site likely uses Matt's lib for that functionality: https://github.com/mholt/json-to-go

Some annoying moments in Golang
https://mholt.github.io/json-to-go/ is a nice tool for generating a struct definition to fit some sample JSON.

Need a pointer on how I can unmarshal this json
json-to-go is your friend.

Ask HN: What are some Golang tools you can't live without?
JSON to struct. I use this about 100 times a day, no joke.

convert interface{} to []interface{}
Do your best to get static types on everything. Play a game with yourself where interface{} is banned and try to do your work. One of the most common sources of such loosely-typed values in JSON, so I'll point out this automatic struct generator for instance. If you have questions about a specific place you don't see how to avoid interface, feel free to ask. Every once in a while I do have to reach for something like this, but it should be rare.

how to efficiently create structs to match the json response
But given we know ChatGPT can't accurately generate structs from even moderately complex json objects why bother doing all of that legwork of verifying and chiding chatgpt, when you can just drop it into a tool like https://mholt.github.io/json-to-go/ and get a correct struct in a fraction of the time?
- How to parse a Kubernetes YAML in Go?
- Is there a library or tool I can use to avoid manually setting json keys i.e. ‘json:”name”’ next to fields in structs?

Do we have any vscode plugin to convert json to struct in Go?
I use https://marketplace.visualstudio.com/items?itemName=maracko.json-to-go, which is an extension version of https://mholt.github.io/json-to-go/

Need help with getting the grandchild in nested JSON
I think using struct in such cases is almost always the right approach. There are tools which generates go structs from json this.
What are some alternatives?
When comparing go-cmp and JSON-to-Go you can also consider the following projects:
Testify - A toolkit with common assertions and mocks that plays nicely with the standard library
Golang-PDF-to-Image-Converter - This project will help you to convert PDF file to IMAGE using golang.
realize - Realize is the #1 Golang Task Runner which enhance your workflow by automating the most common tasks and using the best performing Golang live reloading.
go-sanitize - 🛁 Lightweight Go library providing robust string sanitization and normalization utilities
go-testdeep - Extremely flexible golang deep comparison, extends the go testing package, tests HTTP APIs and provides tests suite
sonic - Sonic is a Go library for network and I/O programming that provides developers with a consistent asynchronous model, with a focus on achieving the lowest possible latency and jitter in Go.
