skills last updated apr 23 2025 introduction cloudinary s latest javascript sdk is designed to provide a simpler and more enhanced developer experience than the legacy javascript sdk this guide explains how to migrate your javascript code from the cloudinary core library legacy javascript sdk to the js url gen library key improvements in the js url gen library 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 the js url gen library the action based syntax used in the js url gen library may cause urls to be formed differently from those generated by the cloudinary core legacy library for example url generated with the cloudinary core legacy 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 js url gen library see the javascript sdk guide on this page introduction key considerations installation migrating cloudinary instance configuration migrating asset instance configuration migrating delivery urls migrating responsive functionality key considerations the cloudinary core library is very different from the cloudinary url gen library in its architecture and usage so migration paths depend on your current usage of the cloudinary core library you can use both the cloudinary core 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 url gen into your application and slowly migrate your functionality piece by piece until you are able to remove all cloudinary core functionality the instructions in this guide assume you are using javascript within a modular environment installation install the cloudinary url gen package using migrating cloudinary instance configuration using the legacy javascript sdk you may be configuring your cloud name and other configuration parameters in a cloudinary instance there is an equivalent cloudinary object in cloudinary url gen for example this cloudinary core code is similar to this cloudinary url gen code migrating asset instance configuration you can also set configuration parameters in the imagetag or url methods in the javascript sdk v1 this is similar to setting the parameters on a per asset instance in cloudinary url gen for example setting cloud_name in a url is similar to setting cloudname in a cloudinaryimage note if you use the cloudinary instance configuration you don t need to add configuration parameters to your asset instances migrating delivery urls using cloudinary core configuration and transformation parameters are specified in json syntax for example using cloudinary url gen you can use the createcloudinarylegacyurl function to pass in the same json and return the same url which you can then use as the source for your image tag 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 for objects such as layer textlayer fetchlayer and transformation you need to import the relevant classes from cloudinary url gen backwards caution if you have a large number of assets we recommend you migrate using the createcloudinarylegacyurl 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 things to know before migrating to the js url gen library 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 which for the above example is the resulting url is migrating responsive functionality if you are using the responsive functionality offered in cloudinary core you will have to replace this code entirely when using the latest javascript sdk for this you need to install the cloudinary html package from frontend frameworks then use the respons...
