Enable es modules support

[MaciejWiatr]

Currently library doesn't seem to work when trying to import it using es module syntax following snippet works just fine:

import { Injectable } from '@nestjs/common';
const ogs = require('open-graph-scraper');
import CreateUrlReq from './dtos/CreateUrlReq.dto';

@Injectable()
export class UrlService {
  private async scrapOgData(url: string) {
    const ogData = await ogs({ url });
    return ogData.result;
  }

  async saveUrl(dto: CreateUrlReq) {
    return await this.scrapOgData(dto.url);
  }
}

but when im trying to import it with following code

import { Injectable } from '@nestjs/common';
import ogs from 'open-graph-scraper';
import CreateUrlReq from './dtos/CreateUrlReq.dto';

@Injectable()
export class UrlService {
  private async scrapOgData(url: string) {
    const ogData = await ogs({ url });
    return ogData.result;
  }

  async saveUrl(dto: CreateUrlReq) {
    return await this.scrapOgData(dto.url);
  }
}

it throws

Can you possibly fix that? 🤔

Thanks for your awesome work!

Looks like you're using typescript. Setting the esModuleInterop flag to true in the tsconfig compilerOptions will fix the import.

It worked, thanks :)
