Angular SDK v2 (Beta)

Important
The Angular frontend framework library is currently in BETA. There may be minor changes to parameter names or other implementation details before the general access release. We invite you to try it out. We would appreciate any feedback via our support team.

  • Video rendering is not supported in this release.

Quick start

If you're ready to get coding, jump straight to our Quickstart guide. Otherwise, keep reading to get a more in-depth understanding of the Angular frontend framework library.

Overview

Cloudinary's Angular frontend framework library provides image rendering capabilities and plugins that you can implement using code that integrates seamlessly with your existing Angular application.

Related topics
This guide relates to the latest released version of the Cloudinary Angular library, released from the frontend-frameworks GitHub repository.

  • For details on all new features and fixes from previous versions, see the CHANGELOG.
  • See the Angular migration guide for information on migrating to Cloudinary's Angular SDK v2.

Architecture

The Angular frontend framework library must be used in conjunction with the Cloudinary JavaScript SDK to provide all of Cloudinary's transformation and optimization functionality.

Two GitHub repositories provide all the functionality:

  • js-url-gen contains all the functionality required to create delivery URLs for your Cloudinary assets based on the configuration and transformation actions that you specify. All the js-url-gen functionality is installed through the @cloudinary/url-gen package.
  • frontend-frameworks contains the framework libraries and plugins that can be used to render images and videos on your site. There are different installation packages for each framework, so for example, React is installed through @cloudinary/react, and Angular is installed through @cloudinary/angular.

Full example

This example shows a transformation URL being created using the @cloudinary/url-gen package, and rendered using Angular. It demonstrates the use of tree shaking to reduce the bundle size, which explains why there are so many import statements.

sample transformation

This code creates the URL required to deliver the front_face.jpg image with the following transformations applied:

  • Crop to a 150x150 thumbnail using face-detection gravity to automatically determine the location for the crop
  • Round the corners with a 20 pixel radius
  • Apply a sepia effect
  • Overlay the Cloudinary logo on the southeast corner of the image (with a slight offset). The logo is scaled down to a 50 pixel width, with increased brightness and partial transparency (opacity = 60%)
  • Rotate the resulting image (including the overlay) by 10 degrees
  • Convert and deliver the image in PNG format (the originally uploaded image was a JPG)

And here's the URL that is generated from the above code:

Installation

Install Cloudinary's JavaScript and Angular packages using the NPM package manager:

Copy to clipboard
npm i @cloudinary/url-gen @cloudinary/angular --save

Configuration

You can specify the configuration parameters that are used to create the delivery URLs, either using a Cloudinary instance or per image/video.

Note
Specify the configuration parameters in camelCase, for example cloudName.

Cloudinary instance configuration

If you want to use the same configuration to deliver all your media assets, it's best to set up the configuration through a Cloudinary instance, for example:

Copy to clipboard
// In your app.module.ts inject the library:
import {CloudinaryModule} from '@cloudinary/angular';

imports: [
  ...,
  CloudinaryModule
],
...
Copy to clipboard
// In your component.ts use `@cloudinary/url-gen` to set your configuration.

import {Component, OnInit} from '@angular/core';
import {Cloudinary, CloudinaryImage} from '@cloudinary/url-gen';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
})

export class AppComponent implements OnInit{
  img: CloudinaryImage;

  ngOnInit() {

    // Create a Cloudinary instance, setting some Cloud and URL configuration parameters.
    const cld = new Cloudinary({
      cloud: {
        cloudName: 'demo'
      }
    });

    // cld.image returns a CloudinaryImage with the configuration set.
    this.img = cld.image('sample');

    // The URL of the image is: https://res.cloudinary.com/demo/image/upload/sample
  }
}
Copy to clipboard
<!-- In your view add the advanced-image component and pass your Cloudinary image. -->
<advanced-image [cldImg]="img"></advanced-image>

You can set other configuration parameters related to your cloud and URL as required, for example, if you have your own custom domain name, and want to generate a secure URL (HTTPS):

Copy to clipboard
// Create a Cloudinary instance, setting some Cloud and URL configuration parameters.
const cld = new Cloudinary({
  cloud: {
    cloudName: 'demo'
  },
  url: {
    secureDistribution: 'www.example.com', 
    secure: true 
  }
});

// This creates a URL of the form: https://www.example.com/demo/image/upload/sample

Asset instance configuration

If you need to specify different configurations to deliver your media assets, you can specify the configuration per image/video instance, for example:

Copy to clipboard
// In your app.module.ts inject the library:
import {CloudinaryModule} from '@cloudinary/angular';

imports: [
  ...,
  CloudinaryModule
],
...
Copy to clipboard
// In your component.ts use `@cloudinary/url-gen` to set your configuration.

import {Component, OnInit} from '@angular/core';
import {CloudinaryImage} from '@cloudinary/url-gen/assets/CloudinaryImage';
import URLConfig from '@cloudinary/url-gen/config/URLConfig';
import CloudConfig from '@cloudinary/url-gen/config/CloudConfig';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
})

export class AppComponent implements OnInit{
  img: CloudinaryImage;

  ngOnInit() {

    // Set the Cloud configuration and URL configuration
    const cloudConfig = new CloudConfig({cloudName: 'demo'});
    const urlConfig = new URLConfig({secure: true});

    // Instantiate and configure a CloudinaryImage object.
    this.img = new CloudinaryImage('docs/shoes', cloudConfig, urlConfig);

    // The URL of the image is: https://res.cloudinary.com/demo/image/upload/docs/shoes
  }
}
Copy to clipboard
<!-- In your view add the advanced-image component and pass your Cloudinary image.-->
<advanced-image [cldImg]="img"></advanced-image>

Transformations

The @cloudinary/url-gen package simplifies the generation of transformation URLs, and includes special components and directives for easy embedding of assets in your Angular application.
