Typical scenario

• content of a CMS page isn’t decoupled from styles

• content of a CMS page is large and confusing

• content manager tries to change a CMS page

• the layout is destroyed

• nobody knows why

Possible solutions

Database backups

• hopefully one with the last stable content

• time consuming and complicated to restore

• has to be done by a developer

CMS pages under version control

• has every version of the content

• can be restored in seconds

• can be done by a content manager in the backend

Example - Wordpress

• it’s called revision

• every save creates a new rowin the database

• versions can be compared

• older versions can be restoredeasily

Is that possible with Magento 2?

Installation

• Add the repository to the repositories section of your composer.json file

"repositories": [

{

"type": "vcs",

"url": "git@github.com:GordonLesti/ContentVersion.git"

}

],

• Require the module and install

composer require lesti/module-content-version:dev-master

Example - ContentVersion

• creates version with eventcms page save after

• send Ajax request to compareversion x with y

• sebastian/diff compares xwith y

• send Ajax response with thediff back to client

Find ADDs, REMOVE s and MATCHs

• start at ai ,j

• end at a1,1

• prefer maximum or diagonal if there is more than one maximum value

• every step• left is a ADD• top is a REMOVE• diagonal is a MATCH
