Sure, you have templates and generate HTML, but sometimes you just need
one more tweak on your pages before they go out the server.
dom-middleware to the rescue.
npm install dom-middleware
var path = ;var express = ;var dom = ;domjquery = true;var app =
This is middleware-middleware, it creates a substream of middleware that
works on a DOM as a response instead of a raw text stream. This allows
you to do complex transformations on the server using client side
technique. When you are all done, the resulting
sent out the response as html.
This has some overhead, you should benchmark yourself to see.
It's about that simple, note that this is using
jsdom, combined with middleware. The
'trick' that makes it work is in intercepting
response objects when the content type is
text/html. The approach is:
endwith a buffering version
end, build up a DOM and hand it to your functions
Becuase this is hooking response, you will likely need to put it high in your middleware chain. Like first.
