foreword

• Used to automatically modify the version number in the electron-vite total package
• Modify content package.json and nodejs script content

1. Node.js

API call of basic nodejs

import path from "path";
import fs from "fs";
import {
    
     exec } from "child_process";
// 读取json文件、读取自定义配置文件
const url = path.join(process.cwd(), "package.json");
const json = fs.readFileSync(url, "utf-8");
const pkg = JSON.parse(json);
try {
    
    
// 修改build的version
  pkg.version = process.env.npm_config_setv;
// 写入文件
  fs.writeFileSync(url, JSON.stringify(pkg, null, 2));
  const build = exec("npm run build");
  build.stdout.on("data", (data) => console.log(data));
} catch (error) {
    
    
  console.log("error", error);
}

Two, package.json

1. Add script script

    "buildVersion": "node build.js --version"

2. Command line input

npm run buildVersion --setv = 2.3.4

• The version in package.json is automatically modified.
• Then run the packaging command directly through exec in child_process.
