Many developers face the challenge of using external libraries in Angular that are not officially supported, such as Clappr and HashWords. The desire is to integrate these libraries seamlessly into an Angular project, almost treating them like native Angular libraries. So, what strategies can we employ to enable Angular to work with external libraries/modules effectively?
To include the library file in index.html, simply add a script tag referencing it. To access the variables provided by the library within a component, declare them outside of the component class like so: declare var Clappr: any;
If the library is an ES6 module, you can easily import it.
For libraries that are just JS files, you can include them by adding the file path to the scripts array in your angular.json file, as if you were using a <script> tag in index.html.
If there are type definitions available, you can add them to the types array in typescript.json.
Check out this helpful guide on how to do all of this:
If you prefer not to have third party libraries as global variables, you can make them injectable. This process may be more complex, but it's quite neat.
Here's a guide on how to achieve that:
Below are the steps I followed to integrate Clappr into my Angular 9 project:
npm install clapprangular.json: "architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"scripts": [
"node_modules/clappr/dist/clappr.min.js"
],
"styles": [
"./src/styles.css"
]
},
"test": {
"builder": "@angular-devkit/build-angular:karma",
"scripts": [
"node_modules/clappr/dist/clappr.min.js"
],
"styles": [
"./src/styles.css"
]
}
}
index.d.ts and define Clappr as follows:declare module 'clappr';
import * as Clappr from 'clappr';
npm i clapprapp.component.tsWhen using Clappr with Angular CLI, you can start by executing the following command:
npm i clappr
https://www.npmjs.com/package/clappr
After that, proceed with the provided instructions.
