Vue.js Migration Guide | Documentation

Cloudinary's Vue.js SDK is designed to provide a simpler and more enhanced developer experience. This guide explains how to migrate your Vue.js code from the cloudinary-vue library (legacy SDK) to the latest Vue.js SDK, which includes @cloudinary/vue from the frontend-frameworks library together with @cloudinary/url-gen from the js-url-gen library.

Key improvements in the Vue.js SDK:

• A new action-based syntax, designed to make building delivery URLs and transformations more logical and discoverable.
  • When compiled to the final delivery URL, each action (including any action qualifiers) represents a different component (separated by a '/'), for example: /c_scale,w_400/f_auto/q_auto/, rather than /c_scale,f_auto,q_auto,w_400/.
• Newly added autocomplete to list options and parameters and ensure only those that are supported can be used together.
• A smaller bundle size - you only need to import what you want to use.

Things to know before migrating to @cloudinary/vue + @cloudinary/url-gen

The action-based syntax used in the js-url-gen library (@cloudinary/url-gen) may cause URLs to be formed differently from those generated by the cloudinary-vue library.

For example:

• URL generated with the cloudinary-vue library:
  https://res.cloudinary.com/demo/image/upload/c_scale,f_auto,q_auto,w_400/sample.jpg
• URL generated with the js-url-gen library:
  https://res.cloudinary.com/demo/image/upload/c_scale,w_400/f_auto/q_auto/sample.jpg

Even if the delivered media file looks and behaves identically, changes to URLs can have the following implications:

• You may see a one-time increase in transformation counts
• You may see a one-time increase in storage usage for the new derived assets
• You may see a one-time increase in add-on usage when add-on transformation parameters are used in the URL
• CDN caches may need to be warmed with the new derived assets
• If strict transformations are enabled for your product environment (in the Security page of your Console Settings), you need to allow the new transformations
• If you require transformations to be generated eagerly, for example long videos, you need to regenerate these via the latest SDK, using the eager parameter of the explicit method.

To reduce the impact of all of the above, we recommend using the createCloudinaryLegacyURL method for your existing transformation URLs, especially if your existing app delivers a large number of transformed assets. This maintains the formations of the transformations, so the URLs remain the same.

The createCloudinaryLegacyURL function supports only transformation and configuration parameters. It does not help to migrate HTML tags, responsive, placeholder, transparent video or jQuery functionality.

For all new transformation URLs that you add to your application, we recommend using the new action-based SDK syntax offered by the latest version of the SDK.

For full documentation on using the @cloudinary/vue + @cloudinary/url-gen packages in your Vue.js app, see the Vue.js SDK guide.

Cloudinary's Vue.js package (@cloudinary/vue from the frontend-frameworks library) must be used in conjunction with the Cloudinary JavaScript SDK (@cloudinary/url-gen) to provide all of Cloudinary's transformation and optimization functionality. As such, the latest Vue.js SDK is very different from the cloudinary-vue (legacy) library in its architecture and usage, so migration paths depend on your current usage of the Vue.js library.

You can use the cloudinary-vue, @cloudinary/vue and @cloudinary/url-gen packages in your application concurrently, so although not recommended for the long term due to the increased bundle size, you could start by integrating @cloudinary/vue and @cloudinary/url-gen into your application and slowly migrate your functionality piece by piece, until you are able to remove all cloudinary-vue functionality.

Install the required packages using the NPM package manager:

Using the legacy Vue.js SDK, you may be configuring your cloud name and other configuration parameters in a cld-context. This is similar to configuring these parameters in a Cloudinary instance, provided by the @cloudinary/url-gen library, in that the configuration is set once, rather than for each image or video.

For example, setting cloudName and secure in a cld-context element:

is similar to setting cloudName and secure in a Cloudinary instance:

You can also set configuration parameters in cld-image or cld-video elements in the legacy Vue.js SDK. This is similar to setting the parameters on a per asset instance.

For example, setting cloudName in a cld-image element:

is similar to setting cloudName in a CloudinaryImage:

The cld-image component in cloudinary-vue has been replaced by the AdvancedImage component in @cloudinary/vue.

Whereas in the legacy Vue.js SDK you specify transformation parameters in the cld-image component, in the latest SDK they are specified in @cloudinary/url-gen in a CloudinaryImage object that you then pass to the AdvancedImage component.

Here is an example of a cld-image component with configuration and transformation parameters included:

There is no easy migration path from a cld-image component to an AdvancedImage component, but you can use the following process as an intermediate step, to create a URL that you can use as the source for a regular image tag:

1. Convert the cld-image component to JSON. An XML to JSON converter can help with this transition, or you may want to use a script if you have a large number of URLs to convert. The previous example would become:

2. Pass this JSON to the createCloudinaryLegacyURL function, included in the @cloudinary/url-gen library, to return a delivery URL that includes the transformations. Configuration parameters, such as cloud_name, should be included in the function call as this is simply a helper function to build the delivery URL:

3. Use this URL as the source for a regular image tag.

If you have a large number of assets, we recommend you migrate using the

method. If you replace your existing transformations using the new SDK transformation syntax, you may find your URLs are generated in a slightly different way. See

, for the implications of these changes to transformation URLs.

For all new Cloudinary delivery URLs, you should start to use the @cloudinary/url-gen syntax to create a CloudinaryImage that you can use in the AdvancedImage Vue.js component:

The resulting URL is:

The advanced image components (lazy loading, image placeholders and image accessibility) and responsive image settings offered by the legacy Vue.js SDK, are offered as plugins in the latest Vue.js SDK.

When you have migrated your delivery URLs to use the AdvancedImage component, you can use the plugins as follows:

This example shows all four plugins being used, but you can use only one, or any combination, by importing and specifying only those you need.
