The comparison between importing TypeScript and ES2015 modules

I am currently facing an issue with TypeScript not recognizing the "default export" of react. Previously, in my JavaScript files, I used:

import React from 'react';
import ReactDOM from 'react-dom';

However, in TypeScript, I found that I had to use (after some online research):

import * as React from "react"
import * as ReactDOM from "react-dom"

This problem arose when starting a new project after encountering difficulties importing my existing project and compiling it in VS2k15.

Is there any difference between these import methods? Is there a way to specify that

"Module 'react' has no default export"

.

I noticed in the React file the following:

declare module "react" {
    export = __React;
}

Could this be considered a default export?

Additionally, I attempted:

import __React from "react"

but encountered the same error message.

Answer №1

When it comes to default exports, all you need to do is give one of the exports the name "default". This can be achieved with the following code snippet:

export default function MyComponent {
    //do something
}

Alternatively, you can use this approach as well:

function MyComponent {
    //do something
}

export {MyComponent as default};
