3 个 Node 常规操作
获取 cpu 核数
const numCPUs = require('os').cpus().length;console.log(numCPUs);
获取 node 版本
console.log(process.version);
无视上级目录创建目录和文件
if Node > 10.12.0 :
require("fs").mkdirSync(fileDir, {recursive: true,
});
require("fs").writeFileSync(filepath, content);
else
// use before writeFileSyncfunction ensureDirectoryExistence(filePath) {
var dirname = path.dirname(filePath);
if (require('fs').existsSync(dirname)) {
return true;
}
ensureDirectoryExistence(dirname);
require('fs').mkdirSync(dirname);
}
