nodejs中判断windows、mac或linux系统

const os = require('os');if (os.type() == 'windows_NT') {//windows平台}if (os.type() == 'Darwin') {//Mac}if (os.type() == 'linux') {//Linux平台}

window和linux已验证通过，mac待验证

通过当前系统(win,linux)配置文件路径

 utils/index.js:

const os = require("os");const path = require("path");// 通过当前系统(win,linux)配置文件路径let setPathByOs = function (fileName = "") {  var configPath = "";  if (os.type() == "Windows_NT") {    configPath = path.resolve(process.cwd(), fileName);  }  if (os.type() == "Linux") {    configPath = path.resolve(process.execPath, "../", fileName);  }  return configPath;};module.exports = {  setPathByOs,};

app.js中使用：

相对根目录而言 

let { setPathByOs } = require("./utils/index.js");const configPath = setPathByOs("./config_node.json");
