NestLensConfig

ViewWatcher

Methods​

onModuleDestroy()​

onModuleDestroy(): void

Defined in: watchers/view.watcher.ts:93

Gives the engine its render method back.

The engine belongs to the application and outlives this module, so without this the host renders through a watcher whose collector is gone — and a process that builds the module more than once against the same engine, as tests and nest start --hmr do, wraps each round on top of the last: measured at three lifecycles, one render recorded three entries.

Returns​

void
