Convert a Joomla website to an app

Joomla sites are often community, membership or organisation sites — exactly the kind people revisit, which makes them good app candidates.

Key takeawayUse your Joomla home page (or the member dashboard) as the start URL. Joomla 4 and 5's Cassiopeia template is responsive; older templates may need work. Users stay logged in through Joomla's session, stores built with VirtueMart or HikaShop check out as on mobile, and you can add the in-app class through the template's custom code fields.

Template

Cassiopeia (Joomla 4/5) is responsive. Joomla 3 templates vary — test at 360px and check menus, modules in side positions (they stack below content on phones) and tables.

Joomla menus collapse into a toggle on mobile. Add native bottom tabs for the 3–5 most visited menu items.

Logins and members

Joomla user accounts work and persist between app launches. Social login extensions relying on Google won't work inside a WebView.

Stores

VirtueMart and HikaShop carts and checkout work; test payment plugins that redirect to external gateways.

Caching

Joomla's page cache is for guests; logged-in pages aren't cached. If a CDN caches pages, make sure it respects session cookies.

Custom code

Many templates have a custom code or custom CSS field; Cassiopeia supports user CSS/JS files. Use them to add the in-app class and hide web-only modules.
