使用nodejs完成判断哪些项目打包+发版

因为我的多个系统的代码都是在一个文件夹下，可以只修改一个其中一个系统的代码，但是却四个都发版
所以利用nodejs 完成这个需求
git fetch 从远程获取代码库 ci合并请求的⽬标分⽀名称。

git fetch origin $CI_MERGE_REQUEST_TARGET_BRANCH_NAME

git diff 判断有哪些不同

git diff --name-only $CI_COMMIT_BEFORE_SHA origin/master | awk -F/ '{print $1}' | sort -u

子进程运行shell脚本
https://blog.csdn.net/cindy647/article/details/108830841
child_process：node的一个子进程api，可创建一个子进程用于执行命令
// 调用util.promisify方法，返回一个promise,如const { stdout, stderr } = await exec(‘rm -rf build’)

const runShell = async (command, exitShellByMsg = false) => {
    
  const exec = util.promisify(child_process.exec); //
  let shell = await exec(command);
  let data = '';
  return new Promise((resolve, reject) => {
    
    data = shell.stdout;
    if ((exitShellByMsg && shell.stdout.indexOf('shell exit') > 0) || !exitShellByMsg) {
    
      resolve(data);
    }
  });
};

获取命令行参数

process.argv[2]

完整代码如下

const util = require('util');
const child_process = require('child_process'); // 用于运行shell命令

const projects = ['ishmael','isaac','hagar','sarai'];
const env = process.env;
const runShell = async (command, exitShellByMsg = false) => {
    
  const exec = util.promisify(child_process.exec);
  let shell = await exec(command);
  let data = '';
  return new Promise((resolve, reject) => {
    
    data = shell.stdout;
    if ((exitShellByMsg && shell.stdout.indexOf('shell exit') > 0) || !exitShellByMsg) {
    
      resolve(data);
    }
  });
};

const diffChange = async () => {
    
  await runShell("git fetch origin $CI_MERGE_REQUEST_TARGET_BRANCH_NAME");  // git fetch 从远程获取代码库 ci合并请求的⽬标分⽀名称。
  const data = await runShell("git diff --name-only $CI_COMMIT_BEFORE_SHA origin/master | awk -F/ '{print $1}' | sort -u");
  const diffs = data.trim().replace(/\n/g, ',').split(',');
  const isNeedBuildAll = diffs.some(name => name && projects.indexOf(name) < 0); // 如果文件夹名称不在projects里，证明为共用文件夹，需要全部build
  console.info('change files', diffs);
  return isNeedBuildAll ? projects : projects.filter(name => {
    
    return name && diffs.indexOf(name) > -1;
  });
};

const buildChanges = async (names) => {

  }

    // runShell 得到了一个Promise对象
    await runShell(`./build.sh ${
      name} ${
      env.CI_COMMIT_SHORT_SHA}`, true)
    console.log("project--------name-------buildEnd",name)
    index++;
    if (index <= names.length - 1) {
    
      await build();
    }
  };
  return build();
};

const deployChanges = async (names) => {

    const prefix = `${
      envName}_${
      name.toUpperCase()}_SERVER`; // TEST_项目名_SERVER_xx || PRODUCT_项目名_SERVER_xxx
    const server = env[`${
      prefix}_NAME`]; // 服务器名称
    const serverPWD = env[`${
      prefix}_PWD`]; // 服务器密码
    const serverPath = env[`${
      prefix}_PATH`]; // 服务器路径
    if (server) {
    
      await runShell(`./script/ci-deploy.sh ${
      name} ${
      server} ${
      serverPWD} ${
      serverPath}`, true);
    }
    index++;
    if (index <= names.length - 1) {
    
      await deploy();
    }
  };
  return deploy();
};

const main = async () => {
    
  const buildProjectNames = process.argv[2] === 'TEST' ? await diffChange() : projects;
