applyConfigChanges()

Applies given changes to the project config.

View source

Arguments

applyYamlChanges()

Applies changes in project.yaml to the project config.

View source

areChangesPending()

Returns whether project.yaml has any pending changes that need to be applied to the project config.

View source

Arguments

  • $path (string, null) – A specific config path that should be checked for pending changes. If this is null, then true will be returned if there are any pending changes in project.yaml..

Returns

boolean

defer()

Defers an event until all other project config changes have been processed.

View source

Arguments

get()

Returns a config item value value by its path.

View source

Arguments
