go-json VS zerolog

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

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.

Drop-in replacement for the stdlib JSON package: https://github.com/goccy/go-json

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.

3rd party JSON libraries could help if you were comparing JSON. https://github.com/goccy/go-json

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.

Minimal dependencies: julienschmidt/httprouter and goccy/go-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.

go-json for encoding/decoding

Be aware that there is a performance impact compared to using zerolog directly [0] (my uneducated guess is it is likely due to pointer indirection).

Things I can't live without in a new Go project in no particular order:

- https://github.com/golangci/golangci-lint - meta-linter

- https://goreleaser.com - automate release workflows

- https://magefile.org - build tool that can version your tools

- https://github.com/ory/dockertest/v3 - run containers for e2e testing

- https://github.com/ecordell/optgen - generate functional options

- https://golang.org/x/tools/cmd/stringer - generate String()

- https://mvdan.cc/gofumpt - stricter gofmt

- https://github.com/stretchr/testify - test assertion library

- https://github.com/rs/zerolog - logging

- https://github.com/spf13/cobra - CLI framework

FWIW, I just lifted all the tools we use for https://github.com/authzed/spicedb

We've also written some custom linters that might be useful for other folks: https://github.com/authzed/spicedb/tree/main/tools/analyzers

Can you compare it against zerolog?

Hello gophers, I am using https://github.com/uber-go/fx and https://github.com/rs/zerolog for logging.

Hovewer it is not bad to export such a function, if it is done purely for convenience. For example github.com/rs/zerolog works on a logger instances, which can be created manually, but they also provide a github.com/rs/zerolog/blob//log package, which provide you access to the global logger which is more convenient in most cases

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

I use zerolog myself and have seen it being used in production several times. Also they have a list of who uses zerolog

This would be so awesome if it was extending an awesome logger like https://github.com/rs/zerolog. Personally I love zerolog because of how it handles different data types including structs!
