I try to optimize the bundles of magento with the information from devdocs . I try to do it on Magento 2.2.6 but the main issue is that after generating the bundles I get an error from the customer-data regarding

TypeError: $.cookieStorage is undefined; can't access its "setConf" property

Did anyone had this error?

EDIT: After some more investigation looks like this error comes from jquery/jquery.storageapi.min strange think is that only when trying to do it as suggested on Magento Devdocs https://devdocs.magento.com/guides/v2.3/performance-best-practices/advanced-js-bundling.html

  • check if merge js is on then it suggest to make enable only one at a time eigher bundling js or js merge.it would be create problem if both are enable at the same time.

Found the issue, main problem was that the guide in the devdocs has some mistakes in it. To fix this I had to find in my build.js "jquery/jquery-migrate": ["jquery" in the shim section and replace it with "jquery/jquery-migrate": ["jquery", "jquery/jquery.cookie"] so just adding jquery.cookie to the deps fixed it

  • hi vlad, did you succeed to do the buding on 2.2.6? because i saw that the documentation is only for 2.3 version Commented Jan 31, 2019 at 10:24

  • I get error after adding code from step 4 of part 2 of the guide. The code that should configure requirejs to use bundles. After i rerun the r.js -o command i get Error: TypeError [ERR_INVALID_CALLBACK]: Callback must be a function at maybeCallback (fs.js:128:9) Commented May 17, 2019 at 19:07
  • @Vlad Patru, hi could you please share your skype so I can get your help in advanced JS bundling? The only issue is that all my advanced JS bundles load on the catalog page which should only load default and catalog.js bundles. Commented Apr 24, 2020 at 11:43
