HmrModuleHandler

Reloads THandler and optional TMiddleware modules on HMR updates.

Call handle() from your HmrAware.onHmr() for standard reload behavior, or write a fully custom onHmr() and skip this class.

This is only useful during development.

class HmrModuleHandler<
    THandler,
    TMiddleware = void,
    TArtifacts = unknown
>

Unloads or reloads the modules affected by an HmrUpdateEvent, scoped to the handler and middleware directories.

public async handle(event: HmrUpdateEvent): Promise<void>

Links the handler to its source file so a later update can unload it.

public trackHandler(
    file: string,
    handler: THandler
): void

Links the middleware to its source file so a later update can unload it.

public trackMiddleware(
    file: string,
    middleware: TMiddleware
): void
