What is the best way to bring npm packages into an Angular project?

Is there a way to import a package called cssdom into Angular successfully?

For example, I tried importing it like this:

import * as CssDom from "cssdom";

However, I encountered the following error:

https://i.sstatic.net/LzZwQ.png

When attempting to create a new instance of CssDom using the code below:

const css = '.container { background-color: white; }';
const cssdom = new CssDom(css)

I also tried another method like this:

import {CssDom} from 'cssdom'

Is there a specific approach to importing third-party packages into Angular? Vue.js makes it simple, but it seems more challenging with TypeScript/Angular!

Answer №1

To begin, make sure to install cssdom by running the following command:

$ npm i cssdom

One way to solve the issue is to add the script to your angular.json file:

  "scripts": [
     ...
    "../node_modules/cssdom/cssdom.js"
     ...
],

Then, you can utilize cssdom in your project like this:

declare const CssDom:any;

...

const css = '.container { background-color: white; }';
const cssdom = new CssDom(css)

Alternatively, you can implement the solution like this:

declare var CssDom:any;

import "cssdom";
