Phones and tablets

fbadmin works in the browser of a phone or tablet, so you can check on your servers away from a desk. Nothing needs installing or switching on: the layout adapts to the screen size.

Screen	Layout
Phone (narrower than 640 px)	The Object Explorer is a drawer, the toolbar buttons are in a ⋯ menu, one panel at a time, dialogs fill the screen.
Tablet (640–1023 px, and touch screens up to 1366 px such as an iPad in landscape)	The desktop layout with a collapsible Object Explorer and the ⋯ menu.
Desktop (1024 px and wider, with a mouse)	Unchanged.

On a phone

• Start page. If servers are registered, fbadmin opens the multi-server overview. Each database is a card with its status, attachments, transactions, OAT gap, long transactions, last backup and replication. Dashboard and Performance open the database.
• Object Explorer. Tap ☰ to open it. Tap a server, database or object to open it: the drawer closes and its dashboard or properties are shown. Tap the arrow in front of a row to expand it without opening it. To close the drawer, tap outside it, swipe it to the left, tap ×, or press Escape.
• Context menus. Touch and hold a row in the Object Explorer, or tap the ⋮ button on the selected row. The menu opens as a sheet along the bottom of the screen. Tap outside it to close it.
• Toolbar. ▦ Overview stays in the top bar. The other buttons (Query Tool, Add server, Schedules, Alerts, Library, Processes, Preferences, the theme and, in server mode, your user menu with Sign out) are in the ⋯ menu.
• Tabs. Open tabs form a strip that scrolls sideways. One panel is shown at a time, full width.
• Tables. Wide tables such as attachments, transactions and query results scroll sideways inside their own box. The page itself does not.
• Dialogs fill the screen, with labels above the fields and a × button to close them.

Quick actions

These work comfortably with touch:

Task	Where
Health of every server	▦ Overview (the start page)
Attachments, running statements, transactions; Disconnect an attachment, Cancel a statement	database dashboard → Monitor
Long transactions and who holds the OAT	database menu → Transactions & OAT
Live counters and charts	database menu → Performance dashboard
Scheduled jobs, run history, Run now (▶)	⋯ → Schedules
Alert rules and sent alerts	⋯ → Alerts
Replication status	database menu → Replication
Recent firebird.log	server menu → Server log
A quick SELECT	⋯ → Query Tool, or the database menu → Query Tool

In the Query Tool, the toolbar is one row that scrolls sideways and the editor is shorter, so the results stay in view.

The table designer, ERD, visual query builder and other editing tools open on a phone without breaking the page, but they need a bigger screen to be comfortable.

On a tablet

The Object Explorer is a sidebar (260 px wide at first). ☰ hides or shows it, and fbadmin remembers your choice in the browser. Context menus open next to the row, as on a desktop.

On touch screens, tree rows, menu items and toolbar buttons are at least 44 px high, and the selected tree row has a ⋮ button for its context menu. This applies to touch laptops too.

The canvases work with fingers:

• ERD: drag the background to pan, drag a table's header to move it, and pinch with two fingers to zoom around the pinch point. To create a foreign key, drag a column's ● (it has a larger, invisible touch area) onto another column.
• Query builder:
• Drag a table by its header, and pinch or use the zoom buttons (40–150 %).
• One finger still scrolls the canvas.
• Dragging a column onto another column needs a mouse (HTML drag and drop does not work with touch). Instead, tap ⇄ next to a column, then ⇄ next to a column of another table.
• Column rows are 40 px high.
• Table designer: the grids of columns, constraints, indices and triggers scroll sideways instead of squeezing their fields, and checkboxes and buttons are finger-sized.

Add to the home screen

fbadmin has a web app manifest and icons, so you can add it to your home screen. It then opens in its own window without the browser's address bar.

• iPhone and iPad (Safari): tap Share, then Add to Home Screen.
• Android (Chrome): open the browser menu, then Add to Home screen or Install app.

fbadmin has no service worker and no offline mode. This is deliberate: it is a live administration tool, and a cached page or cached numbers could show a database as healthy when it is not. Without a connection to the fbadmin server, the page does not load.

To reach fbadmin from a phone, run it in server mode behind HTTPS (see deployment), and sign in as usual. Two-factor sign-in works on phones as well.

Accessibility

The phone and tablet layouts are checked with axe in the light, dark and high-contrast themes, including the WCAG 2.2 target-size rule. The drawer moves focus into itself when it opens and back to ☰ when it closes, and the rest of the page is inert while it is open. Animations are turned off when the system asks for reduced motion.

Limitations

• Full editing tools (table designer, ERD, query builder canvas, schema diff) are usable but cramped on a phone; use a tablet or desktop for them.
• Dragging from the Object Explorer onto the query builder, and resizing grid columns, need a mouse. On a tablet, add tables with Add table instead.
• On touch screens there are no hover tooltips.
