Typescript：如何解决嵌入式定义中缺少的导出？

Question

I'm using a package from npm, let's say foo . This package has an embedded definiton file node_modules/foo/index.ts.d . However, there is an export missing from this file. Therefore, typescript won't let me compile, giving me the error: Module '.../foo' has no exported member 'Bar'.

How to I augment, replace or fix the definiton for the foo package?

Answer 1

You can use module augmentation to add the missing export. Simply place the following above your import statement:

declare module 'foo' {
    export let Bar: {
       example_name: string, // etc
    };
}

import {Bar} from 'foo';
