[Node.js] Chrome Zstd Go Rust nginx 初体验

Facebook Zstd

Zstd 注意1.51版本性能更好. lz4也是不错的可惜Chrome不支持.

zstd > brolti > gzip

cpu占用率解压缩压缩都好

Chrome

Caniuse里看到了zstd

chrome >= 118 打开可用,默认不可用

地址栏输入

chrome://flags 
enable-zstd-content-encoding //enabled

nginx的支持

zstd-nginx-module(第三方)

# centos readhot fedora rocky linux
yum install libzstd-devel

# debian ubuntu
apt install zstd

# alpine
apk add --no-cache zstd-dev

istio k8s的支持

isto filter支持

Golang Server Zstd

查看评测数据 github.com/klauspost/compress/zstd 数据好一些, 比必须ssl才能用的br好,好于gzip.

package main

import (
	"fmt"
	"github.com/CAFxX/httpcompression"
	"github.com/klauspost/compress/gzip"
	"io"
	"net/http"
	"os"
)

func main() {

	data, err := os.ReadFile("./data.json")
	if err != nil {
		fmt.Println(err)
		return
	}
	handler := http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		w.Header().Set("Content-Type", "text/plain")
		str := string(data)
		io.WriteString(w, str)
	})
	zstdComp, err := zstd.New()
	compression := httpcompression.ZstandardCompressor(zstdComp)
	compress, _ := httpcompression.DefaultAdapter(compression) 

	http.Handle("/", compress(handler))
	http.ListenAndServe("0.0.0.0:8080", nil)
}

Rust Salvo Zstd

Cargo.toml

[package]
name = "zstd_salvo"
version = "0.1.0"
edition = "2021"

[dependencies]
salvo = { version="0.63.1", features = ["compression", "serve-static"] }
tokio = { version = "1", features = ["macros"] }
tracing = "0.1.27"
tracing-subscriber = "0.3"

main.rs

use salvo::compression::Compression;
use salvo::prelude::*;

#[tokio::main]
async fn main() {
    tracing_subscriber::fmt().init();

    let base_dir = std::env::current_exe()
        .unwrap()
        .join("../../../static")
        .canonicalize()
        .unwrap();
    println!("Base Dir: {:?}", base_dir);

    let router = Router::new()
       .push(
            Router::with_hoop(Compression::new().enable_zstd(CompressionLevel::Minsize))
                .path("")
                .get(StaticFile::new(base_dir.join("data.json"))),
        );

    //没起效果还是 gzip encoding 在response headers里,是个bug需要fork
    
    let acceptor = TcpListener::new("127.0.0.1:5800").bind().await;
    Server::new(acceptor).serve(router).await;
}

Java

等待Spring Boot 实现

NodeJS

等待Nest.js @fastify/compress 实现

效果

打开Chrome控制台,随意请求

rust go

查看请求 Request Headers是否为

Accept-Encoding: gzip, deflate, br, zstd

Response Headers Content-Encoding: zstd

5.7Mb的文件最终为485Kb
