What is the process of asynchronously importing a module's exported function using dynamic imports and then executing it?

When working with asynchronous callbacks in a promise

promise.then(async callbackResultValue => { //here })

I experimented with this code:

const browserd = await import('browser-detect');
if (typeof browserd === 'function') { 
    const browserinfo = browserd();
}

The result I received was:

[ts] Cannot invoke an expression whose type lacks a call signature. Type 'never' has no compatible call signatures.

After that, I attempted the following:

const browserd:Function = await import('browser-detect');

This generated the error message:

[ts] Type 'typeof import("<path-to-npm-module>' is not assignable to type 'Function'. Property 'apply' is missing in type 'typeof import("<path-to-npm-module>'.

Answer №1

While encountering a similar issue, I discovered that the object in the returned Promise may not be the actual function itself, but rather an object containing a property named default whose value is the desired function.

Although there are still aspects of exporting that elude me, the following code proved successful in my case:

    import('moduleWithADefaultExportOfAFunction')
        .then(importedModule => importedModule.default());
