pptxgenjs: This expression is not constructable

Question

I am new to NodeJS.

I'm trying to write the following code for a NodeJS application (in src/index.ts):

import pptxgenjs from 'pptxgenjs';
const pres = new pptxgenjs();

Source

But the Typescript compiler gives me the following error:

This expression is not constructable.
Type 'typeof import("########/node_modules/pptxgenjs/types/index")' has no construct signatures.

My tsconfig.json looks like this:

{
    "compilerOptions": {
        "module": "NodeNext",
        "moduleResolution": "NodeNext",
        "target": "ES2020",
        "sourceMap": true,
        "outDir": "dist",
        "esModuleInterop": true,
        "allowSyntheticDefaultImports": true
    },
    "include": ["src/**/*"]
}

What can I do to resolve this?

Answer 1

It looks like I am using the exact same code on a typescript project and it works for me.

import pptxgen from "pptxgenjs";
let pres: pptxgen
pres = new pptxgen();

It is inside a NextJs typescript project.

Below is the beginning of my tsconfig.json file. Hope this helps.
