U

Parameters#

Name

Type

Description

token

Token<U>

The token for the service type of interest.

Returns#

Promise<null | U>

A promise which resolves to an instance of the requested service, or null if it cannot be resolved.

Notes#

Services are singletons. The same instance will be returned each time a given service token is resolved.

If the plugin which provides the service has not been activated, resolving the service will automatically activate the plugin.

User code will not typically call this method directly. Instead, the optional services for the user’s plugins will be resolved automatically when the plugin is activated.

Inherited from#

Application.resolveOptionalService

Defined in#

node_modules/@lumino/application/types/index.d.ts:267

Type

Description

token

Token<U>

The token for the service type of interest.

Returns#

Promise<U>

A promise which resolves to an instance of the requested service, or rejects with an error if it cannot be resolved.

Notes#

Services are singletons. The same instance will be returned each time a given service token is resolved.

If the plugin which provides the service has not been activated, resolving the service will automatically activate the plugin.

User code will not typically call this method directly. Instead, the required services for the user’s plugins will be resolved automatically when the plugin is activated.

Inherited from#

Application.resolveRequiredService

node_modules/@lumino/application/types/index.d.ts:247

start#

start(options?): Promise<void>

Start the application.

Parameters#

Name

Type

Description

options?

IStartOptions

The options for starting the application.

Returns#

Promise<void>

A promise which resolves when all bootstrapping work is complete and the shell is mounted to the DOM.

Notes#

This should be called once by the application creator after all initial plugins have been registered.

If a plugin fails to the load, the error will be logged and the other valid plugins will continue to be loaded.

Bootstrapping the application consists of the following steps:

  1. Activate the startup plugins

  2. Wait for those plugins to activate

  3. Attach the shell widget to the DOM

  4. Add the application event listeners
