# JBrowseRootConfig

Auto-generated config schema for the current JBrowse release — see the
[config guide](https://jbrowse.org/jb2-staging/docs/config_guide) for concepts. Built into JBrowse core.
[View source](https://github.com/GMOD/jbrowse-components/blob/main/packages/app-core/src/JBrowseConfig/index.ts).

this is a config model representing a config.json (for jbrowse-web) or
somefile.jbrowse (for jbrowse-desktop, where configs have the .jbrowse
extension)

also includes any pluginManager.pluginConfigurationSchemas(), so plugins that
have a configurationSchema field on their class are mixed into this object

## Config slots

Slot types (`fileLocation`, `frozen`, ...) are explained in the
[config slot types reference](https://jbrowse.org/jb2-staging/docs/config_guides/slot_types). Slots a base
configuration contributes are listed here too, so this table is the whole
surface.

<!-- prettier-ignore -->
| Slot | Description |
| --- | --- |
| <span id="slot-plugins">**plugins**</span><br><code>types.array(types.frozen&lt;PluginDefinition&gt;())</code> | defines plugins of the format ```typescript type PluginDefinition= { umdUrl: string, name:string } \| { url: string, name: string } \| { esmUrl: string } \| { cjsUrl: string } \| { umdLoc: { uri: string } } \| { esmLoc: { uri: string } } \| ``` |
| <span id="slot-assemblies">**assemblies**</span><br><code>types.array(assemblyConfigSchema)</code> | configuration of the assemblies in the instance, see BaseAssembly |

Always uses frozen for performance - editing creates temporary MST models. |

| <span id="slot-defaultsession">**defaultSession**</span><br><code>types.optional(types.frozen(), { name: 'New Session', })</code> | the session loaded when no session is otherwise specified, e.g. the initial view shown on first load |
| <span id="slot-preconfiguredsessions">**preConfiguredSessions**</span><br><code>types.array(types.frozen())</code> | named sessions bundled with the config that a user can open from the session selector |
