How to use js in nginx

#linux #tutorial #javascript #devops

  1. I heard that js can be used in nginx. nginx has use quickjs ,so we can use js in nginx config. That is exciting to me, I want to try it.

  2. But when I see the doc, I am crying. It is so complicated. I have to download source for njs and quickjs, and nginx. After all three source download, I have to run configure \ make && make install . Oh my god

  3. I try to download all the source files

git clone https://github.com/nginx/njs
Enter fullscreen mode Exit fullscreen mode 
 wget http://nginx.org/download/nginx-1.25.3.tar.gz  # 确保版本 ≥ 1.23.0
Enter fullscreen mode Exit fullscreen mode 

# 下载 OpenSSL 源码（以 3.0.8 为例）
wget https://www.openssl.org/source/openssl-3.0.8.tar.gz
tar -zxvf openssl-3.0.8.tar.gz
cd openssl-3.0.8
Enter fullscreen mode Exit fullscreen mode 

 git clone https://github.com/bellard/quickjs
 cd quickjs/
CFLAGS='-fPIC' make libquickjs.a  # 生成位置无关代码
Enter fullscreen mode Exit fullscreen mode 

project_root/
├── nginx-1.25.3/       # Nginx 源码目录
└── quickjs/            # QuickJS 源码目录（需手动创建或克隆）
└── njs/            # QuickJS 源码目录（需手动创建或克隆）
Enter fullscreen mode Exit fullscreen mode 

# 授予当前用户读取权限
sudo chmod -R 755 ../quickjs
Enter fullscreen mode Exit fullscreen mode
  1. I feel so disappointed. We need to configure the file with command below 
./configure  --add-dynamic-module=../njs/nginx --with-openssl=../openssl-3.0.8  --with-cc-opt="-I $(pwd)/../quickjs"  --with-ld-opt="-L $(pwd)/../quickjs"
Enter fullscreen mode Exit fullscreen mode

After configure step, we still need to make and make install

make && sudo make install
Enter fullscreen mode Exit fullscreen mode

I run nginx start .something wrong again, It shows mismatch for njs and nginx. I try to run command

whereis nginx
Enter fullscreen mode Exit fullscreen mode 
nginx: /opt/homebrew/bin/nginx /opt/homebrew/share/man/man8/nginx.8
Enter fullscreen mode Exit fullscreen mode

It seems that I dont use the nginx I compiled. I tried to use direct path for nginx and then It can not find correct config file. So I decide to use all direct path

./objs/nginx -c ~/workspace/nginx-1.25.3/conf/nginx.conf
Enter fullscreen mode Exit fullscreen mode

even if the config file use direct path

Stop the nginx

./objs/nginx -c ~/workspace/nginx-1.25.3/conf/nginx.conf -s stop
Enter fullscreen mode Exit fullscreen mode

start

./objs/nginx -c ~/workspace/nginx-1.25.3/conf/nginx.conf
Enter fullscreen mode Exit fullscreen mode

visit the http://localhost

{
  "message": "Request processed at 1758537787024",
  "stats": {
    "headerCount": 15,
    "customHeaders": 0
  },
  "serverInfo": "GET / HTTP/1.1"
}
Enter fullscreen mode Exit fullscreen mode
