I save data on local storage, but I might change the structure of the data or how I use it, which might break the users that is keeping the old data structure in their local storage. What is the best way to handle this update of local data.

Show a dialog asking the user to backup their current data, just export the localstorage value as a file for backup and then just update the value, if anything goes wrong give them the option to restore

ok I am not doing any of that, how do I make this automatic smoothless and non intrusive

You can skip the backup and restore step

can you just write me an infrastructure for handling this step.
acoustic viper
you can version the data and write migrations
there are probably libs for it but it's not so difficult to write your own: https://levelup.gitconnected.com/an-approach-to-javascript-object-schema-migration-ae1bd9f0ce78
