After July 2021, the 2.3.x release line will no longer receive quality updates, or user guide updates. PHP 7.3 reaches end of support in December 2021 and Adobe Commerce 2.3.x reaches end of support in September 2022. We strongly recommend planning your upgrade now to Adobe Commerce 2.4.x to help maintain PCI compliance.

Merging JavaScript Files

The information on this page is intended for Adobe Commerce 2.3 customers who are on an extended support contract. The Adobe Commerce Merchant Documentation for current releases is published on the Adobe Experience League.

Multiple JavaScript files can be merged into a single, condensed file to reduce page load time. If you open a merged JavaScript file, you will find one continuous stream of text, with line breaks removed. If you are finished with the development process and the code contains no errors, you might consider merging the files.

JavaScript files can be merged only when working in Developer Mode.

Merge your JavaScript files

  1. On the Admin sidebar, go to Stores > Settings > Configuration.

  2. In the left panel, expand Advanced and choose Developer.

  3. Expand the JavaScript Settings section.
