uniapp 有编译前运行脚本入口吗

package.json:

  "scripts": {  
    "h5": "node build.js"  
  },  
// .........  

 "uni-app": {  
    "scripts": {  
      "H5-ABC": {  
        "title": "渠道1",  
        "browser": "chrome",  
        "env": {  
          "UNI_PLATFORM": "h5",  
          "TENANT": ABC"  
        },  
        "define": {  
          "H5-ABC": true  
        }  
      }  
}

build.js

const shell = require('shelljs');  
const os = require('os');  

// Check OS type  
const isWindows = os.platform() === 'win32';  
const isMac = os.platform() === 'darwin';  

// [channel] is the first argument  
const [channel] = process.argv.slice(2);

let basePath;

    basePath = '/Applications/HBuilderX-Alpha.app/Contents/HBuilderX/plugins';  
} else {  
    console.error('Unsupported OS');  
    process.exit(1);  
}  

// 设置 NODE_SKIP_PLATFORM_CHECK 环境变量,否则低版本的window server无法运行HBuilder X的高版本node  
shell.env['NODE_SKIP_PLATFORM_CHECK'] = '1';

    command = `cd ${basePath}\\uniapp-cli\\ && cross-env UNI_INPUT_DIR=%INIT_CWD%\\ UNI_OUTPUT_DIR=%INIT_CWD%\\unpackage\\dist\\build\\${channel} UNI_PLATFORM=h5 UNI_SCRIPT=${channel} NODE_ENV=production ${basePath}\\node\\node bin\\uniapp-cli.js`;

    console.error('Error executing the command');  
} else {

}

terminal:

npm run h5 -- H5-ABC
