PreferencesConfigSchema

Auto-generated config schema for the current JBrowse release — see the config guide for concepts. Built into JBrowse core. View source.

admin/embedder defaults for user-facing preferences, found on the root config as configuration.preferences. Individual users override these at runtime (persisted to localStorage) via the session getPreference reader; a runtime override map layered over config defaults, at app scope.

Config slots

Slot types (fileLocation, frozen, ...) are explained in the config slot types reference. Slots a base configuration contributes are listed here too, so this table is the whole surface.

SlotDescription
configuration.preferences.animationMode
stringEnum (system, enabled, disabled) = 'enabled'		controls feature-layout animations: 'enabled' always animates (the default), 'system' respects the OS prefers-reduced-motion setting, 'disabled' never animates
configuration.preferences.scrollZoom
boolean = false		when true, scrolling the mouse wheel over a track zooms in and out without holding Ctrl. Applies globally to all wheel-zoom views.
configuration.preferences.numberGrouping
boolean = true		when true (the default), numbers are displayed with thousand separators — chr1:1,234,567. Turn it off to render them bare, which is what you want if you copy coordinates out of JBrowse into tools that won't accept the commas. Applies to every displayed number, and takes effect on reload.
configuration.preferences.useWorkspaces
boolean = false		when true, views open in the tabbed/tiled workspace layout rather than stacked vertically. Only the default: a session that names useWorkspaces itself (a shared snapshot, or a session spec carrying a layout) still wins, and a user's own toggle overrides it.
