go-json VS httprouter

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

Following the completion of the series — Secure and performant full-stack authentication system using rust (actix-web) and sveltekit and Secure and performant full-stack authentication system using Python (Django) and SvelteKit — I felt I should keep the streak by building an equivalent system in PURE go with very minimal external dependencies. We won't use any fancy web framework apart from httprouter and other basic dependencies including a database driver (pq), and redis client. As usual, we'll be using SvelteKit at the front end, favouring JSDoc instead of TypeScript. The combination is ecstatic!

Gin is a web framework written in Go. It features a martini-like API with performance that is up to 40 times faster thanks to httprouter. If you need performance and good productivity, you will love Gin.

But, if you care about speed take a look at httprouter. That's the one we're using in our company. It's fast but the biggest downsides for me are:

Mir is a toolkit to develop RESTful API backend service like develop service of gRPC. It adapt some HTTP framework sush as Gin, Chi, Hertz, Echo, Iris, Fiber, Macaron, Mux, httprouter。

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

Also, you seemed to have copied the path.go from Julien Schmidt's httprouter without even thanking or mentioning it in the README, which I think is not a good attitude. Yes, httprouter is BSD-3-Clause licensed, but showing the people that you took the code from some respect, should be a absolute must, in my opinon.

Take this as the high-performing router (I used this in an early demo for the company I worked for when we considered Golang). https://github.com/julienschmidt/httprouter/blob/34250257ea144905c752bfaae80d6885f190daf6/tree.go

The julienschmidt/go-http-routing-benchmark is the julienschmidt/httprouter, but maintenance seemed to have stopped in recent years, so I decided to create my own benchmarker and implement it. I decided to implement bench markers.

As another aside, I will actively discourage Iris. https://github.com/julienschmidt/httprouter/issues/148 https://www.reddit.com/r/golang/comments/b481q7/a_warning_about_githubcomkatarasiris/
