nodejs 生成so文件

Node.js is a runtime environment for JavaScript, which means it is not designed to generate .so files. .so files are shared libraries for Unix and Unix-like systems, and are typically written in C or C++.

However, you can use Node.js to build native add-ons, which are binary modules that can be loaded into Node.js using the require() function. To create a native add-on, you will need to use a build tool like node-gyp, which can compile C or C++ code into a Node.js module.

Here are the steps to create a native add-on using Node.js and node-gyp:

Install node-gyp using npm: npm install -g node-gyp
Create a new directory for your add-on and navigate into it: mkdir my-addon && cd my-addon
Create a new Node.js module: npm init
Install the node-addon-api package: npm install node-addon-api
Create a new C++ file for your add-on, for example: my-addon.cc
Write your C++ code in the my-addon.cc file
Create a binding.gyp file in the same directory as your C++ file, and add the following code:

{
  "targets": [
    {
      "target_name": "my-addon",
      "sources": [ "my-addon.cc" ],
      "include_dirs": [
        "<!DOCTYPE html>"
        "node_modules/node-addon-api"
      ],
      "libraries": []
    }
  ]
}

Run node-gyp configure to generate the build files: node-gyp configure
Run node-gyp build to compile your add-on: node-gyp build
Your add-on should now be compiled and located in the build/Release directory as a .node file, which can be loaded into Node.js using the require() function: const myAddon = require('./build/Release/my-addon.node')

Note that this is just a basic example, and you will need to tailor it to your specific needs. You can find more information and examples in the Node.js documentation and the node-addon-api GitHub repository
