node 文件操作

fs.writeFileSync(
  `./data/xxx.json`,
  JSON.stringify({}, null, "\t")
);

fs.existsSync(path.resolve(filePath, fileName))

fs.mkdirSync(filePath, { recursive: true });


// 创建文件并写入
function writeFileSync(option) {
  let { filePath, fileName, jsonData = {} } = option;
  fs.mkdirSync(filePath, { recursive: true });
  fs.writeFileSync(
    path.resolve(filePath, fileName),
    JSON.stringify(jsonData, null, "\t")
  );
}
