 With this approach, you can benefit from streaming and there is no middleman (less complexity).
 
-Alternatively, you can use the independent [view-engine](https://github.com/patrick-steele-idem/view-engine) module to provide an abstraction that allows pluggable view engines and provides full support for streaming. This is shown in the following sample code:
