如何在 NodeJS / TypeScript 中使用 Promises 获取文件大小

首先，从 NodeJS 标准库导入 stat：

import_stat.ts

import { stat } from "node:fs/promises";

import { stat } from "node:fs/promises";

filesize_async.ts

// Async-await 风格：
const statResult = await stat("myfile.pdf");
const fileSizeInBytes = statResult.size;

// Async-await 风格：
const statResult = await stat("myfile.pdf");
const fileSizeInBytes = statResult.size;

filesize_then.ts

stat("myfile.pdf").then(statResult => {
    const fileSizeInBytes = statResult.size;
    // TODO 你的代码放在这里
});

stat("myfile.pdf").then(statResult => {
    const fileSizeInBytes = statResult.size;
    // TODO 你的代码放在这里
});
