Error: Cannot invoke an expression whose type lacks a call signature

Question

I am brand new to typescript, and I have two classes. In the parent class I have:

abstract class Component {
  public deps: any = {};
  public props: any = {         


        

Answer 1

I had the same error message. In my case I had inadvertently mixed the ES6 export default function myFunc syntax with const myFunc = require('./myFunc');.

Using module.exports = myFunc; instead solved the issue.
