const Format prettifier = true

In case of any breaking change or bug caused by this, set this to false and the whitespace addition in schema generated/consumed would be removed(will go back to default behavior)

Variables

var ComponentTypesSingleton = ComponentTypes{
	Names:                     make(map[string]bool),
	LatestVersionForComponent: make(map[string]string),
}

ComponentTypesSingleton is initialized per meshery instance and acts as a helper middleware between client facing API and capability registry. Examples of names stored in this struct are: core,kubernetes,istio,linkerd
