A jQuery to Vue migration starts by untangling what the current pages actually do. A click handler may update the DOM, trigger another plugin and leave shared state behind for the next screen. On a mixed PHP or server-rendered site, that behavior often spans templates and scripts. I map those chains before replacing selected features with tested Vue 3 components.<\/p>\t\t<\/div>\r\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

I start inside the existing stack. First I trace selectors, event listeners, plugin callbacks and shared objects across the current templates. That reveals which jQuery features can move on their own and which still depend on server-rendered markup or another plugin. The migration order comes from those dependencies.<\/p>

The difficult part is rarely the jQuery syntax. It is the chain of side effects around it: one handler changes a class, another plugin reads that class, and a later AJAX response replaces the same element. I add tests around that behavior before the feature moves, so the replacement component has something concrete to match.<\/p>

New components can then mount inside the existing pages one feature at a time. The rest of the site stays on its current stack while each selected area is separated from global state and given a clear boundary. This keeps the backend out of the rewrite unless a feature genuinely needs it, and gives the team reviewable steps instead of one large switch.<\/p>\t\t<\/div>\r\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
