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.

API: Go, .NET, Rust
For go -> you can actually get away with the standard json encoding package. Or if you want a slightly better one, I prefer goccy/go-json

Rob Pike: Gobs of data (2011)
Someone made a benchmark of serialization libraries in go [1], and I was surprised to see gobs is one of the slowest ones, specially for decoding. I suspect part of the reason is that the API doesn't not allow reusing decoders [2]. From my explorations it seems like both JSON [3], message-pack [4] and CBOR [5] are better alternatives.
By the way, in Go there are a like a million JSON encoders because a lot of things in the std library are not really coded for maximum performance but more for easy of usage, it seems. Perhaps this is the right balance for certain things (ex: the http library, see [6]).
There are also a bunch of libraries that allow you to modify a JSON file "in place", without having to fully deserialize into structs (ex: GJSON/SJSON [7] [8]). This sounds very convenient and more efficient that fully de/serializing if we just need to change the data a little.

Go is 2-3 times slower than JS in a similar code. What makes Go slow in this specific code?
go stdlib json encoding/decoding is incredibly slow, not sure for how much longer because there are drop in replacements now that I think are just as strict and feature parity.

Go with Chi has more ram consumption and less req/s than Koa or Fastify
3rd party JSON libraries could help if you were comparing JSON. https://github.com/goccy/go-json

ogen: spec-first OpenAPI v3 codegen for Go
However, I understand the code that is generated is super optimized. For example, rather than use a router, it does a static code generated router. Rather than use goccy/go-json, it does manual marshalling.

japi is a JSON HTTP API go library with generics
Minimal dependencies: julienschmidt/httprouter and goccy/go-json

Using a json lib other than encoding/json
I suggested using https://github.com/goccy/go-json at my work, since its a drop in replacement for the standard lib, but there are people who apprehensive. In my opinion the performance gains are significant to justify adoption. But I'd like your input.
- Whats the fastest JSON unmarshaling package as of right now?
-
What are your favorite packages to use?
go-json for encoding/decoding

goccy/go-json: A super fast JSON library fully compatible with encoding/json
I develop a super fast JSON library ( https://github.com/goccy/go-json ) for Go .

Jj: JSON Stream Editor
I like jq, but jj is so fast it is my go-to for pretty printing large json blobs. Its parsing engine is available as a standalone google module, and I've used it in a few projects where I needed faster parsing than encoding/json:
```
I don't think there is a way to sort an array, though. However, there is an option to have keys sorted. Personally, I don't think there is much annoyance in that. One could just pipe `jj` output to `sort | uniq -c`.

Library to analyze an arbitrary JSON string
I’m using GJSON, so far so good!

Any way to convert unknown/dynamic json to generic object structure
https://github.com/tidwall/gjson is a relatively sensible library if this is something you need to deal with and the structure is actually unknowable.
- Need help with getting the grandchild in nested JSON
- Double down on python or learn Go
- Ad hoc JSON parsing
-
Ask HN: Why isn't JSON-RPC more widely adopted?
one way could be you peek method using sth like https://github.com/tidwall/gjson
-
Is there a way to parse unstructured data?
That’s because Go is a statically typed language. If you want to easily access the data, you need to know the structure, if you don’t know the structure, then you’re going to have to jump through hoops to get at the data. I would probably try using https://github.com/tidwall/gjson if I were you.
