Utilizing a non-Angular node module in Angular: Best practices

One way to generate QR codes in JavaScript is by using the qrcode module, which can be found at this link.

In pure JavaScript, it's simple to utilize this module:

var QRCode = require('qrcode')

QRCode.toDataURL('I am a pony!', function (err, url) {
  console.log(url)
})

However, when working with Angular, you cannot use "require." Angular uses a different approach:

import { X } from Y

To integrate the qrcode reader into an Angular application, what would X and Y represent? How can this functionality be achieved?

javascriptangulartypescriptrequire

Answer №1

To enhance your TypeScript environment, especially when working with Angular, you can easily add the necessary package and types for full functionality:

npm install --save qrcode && npm install --save-dev @types/qrcode

After installing, you can simply import QRCode from 'qrcode' in your component to start utilizing it within your TypeScript setup.

Answer №2

It really varies based on the specific package you're using. However, for the most part, something along these lines should suffice.

import * as QRCode from 'qrcode'
// Otherwise
import QRCode from 'qrcode'

Another option is if you have bundled the library with Angular CLI, you can instruct typescript to overlook packages without typings by:

declare var QRCode: any;
