Using CamanJs in conjunction with Angular 6

Struggling to integrate camanjs with Angular 6? Wondering how to add the JavaScript library and use it within an Angular project when there are no types available on npm? Here are the steps I followed:

First, install Caman using npm.
Next, add it to angular.json as a script by specifying its path in the node modules directory.
Import it into the component like this:

import * as Caman from 'path to Caman in node_modules'

In ngAfterViewInit, you can use it like this:

ngAfterViewInit() {
      Caman('#image-id', function () {
          this.brightness(10);
          this.contrast(20);
        });
   }

However, upon starting the server, I encountered this error:

Answer 1

Answer №1

To incorporate the library caman into your Angular project, you need to follow these steps:

"scripts": [
    "../node_modules/path-to-caman"
],

If you are using Angular 6, make sure to add the path to caman in the scripts array of angular.json:

"scripts": [
    "node_modules/path-to-caman"
],

After adding the script, declare a variable named Caman in your Component:

declare var Caman: any;

Avoid importing using:

import * as Caman from 'path-to-caman'

This will result in an error message like:

Cannot find module 'caman'.

By simply including the script in the scripts array, it will be accessible globally in your components. Remember to interact with it inside the ngAfterViewInit lifecycle hook for proper DOM element access.
