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.
