您在打字稿中使用的每个 JS 库都需要打字/定义文件吗?

问题描述

你在打字稿中使用的每个 JS 库都需要打字吗?如果没有，那么如何消除错误并使用没有可用定义文件的库

Is it necessary to have typing for every JS library you use in typescript?if not, then how to get rid of errors and make use of a library which doesn't have available definition files

import { NotificationContainer, NotificationManager } from 'react-notifications';

找不到反应通知的类型

推荐答案

没有必要.对于您的示例，您创建了一个文件 react-notifications.d.ts(只要扩展名是 .d.ts，您可以随意命名它，但它会使一致地命名它是有意义的):

It's not necessary. For your example, you create a file react-notifications.d.ts (you can call it anything you like as long as the extension is .d.ts but it makes sense to name it consistently):

declare module "react-notifications" {

    const NotificationContainer: any;
    const NotificationManager: any;
}

这是一个接近最低限度的起点.但是您可以进一步改进那些 any 声明.他们是临时警察.

That's a near-minimal starting point. But you could go a little further and improve on those any declarations. They are a temporary cop-out.
