如何在 Babel 中将 * 导出为命名空间？

Question

I am working on code that is a mixture of JS and TS, using TypeScript 3.8. I wrote the following line:

export * as Easing from './easing';

Which should be fair game in TypeScript 3.8. However, I am compiling using Webpack, and I am not using ts-loader , only babel-loader with the TypeScript preset, and it seems like Babel does not support this syntax. I'm getting this error:

 ERROR in./src/index.ts Module build failed (from./node_modules/babel-loader/lib/index.js): SyntaxError: /home/laptou/projects/my-project/src/index.ts: Unexpected export specifier type 30 | default as Clock, addUpdateListener, after, chain, clock, infinite, tween 31 | } from './clock'; 32 | export * as Easing from './easing'; | ^^^^^^^^^^^ 33 | export type { Tween, TweenOptions, TweenStatus } from './tween'; 34 | export { default as InterpolateTween } from './tween/interpolate'

How can I fix this?

Answer 1

I've asked this question before here: namespace export from index.js

import * as Easing from './easing';
export { Easing }

Answer 2

try this

// ./some/someFile.ts

export function util1 () {
...
}

export function util2 () {
...
}

export function util3 () {
...
}

An on your index or any file you import yow functions

// ./some/index.ts

export * as utils from "./someFile";

If by any means you get some problems.

Change your index.ts to:

import * as utils from "./someFile";

export { utils };

or we could used the old but always trusted default form:

// ./some/someFile.ts

function util1 () {
...
}

function util2 () {
...
}

function util3 () {
...
}

export default {
   util1,
   util2,
   util3
}

at the index

import utils from "./someFile";
export { utils };

// or
export { default as utils } from "./someFile";
