问题
I have a nodejs express 2.0 application and I want to use express 3.0 within it. Tell me please which is state of express 3.0 at now and is there examples of express 3.0 applications?
I saw connect 2.0 has been released, so can I use it with express 2.0 ?
回答1:
I have had the same issue myself with my applications after doing npm install express .
TJ has upgraded version 3 and added/removed some features (better or for worse Im still ascertaining :P )
But the 2 things you need to MAKE sure to change on a default application is change:
app.register..
to:
app.engine
And to know that dynamicHelpers and helpers are no longer there. You have to use
app.locals.use
Strongly recommend reading his migration guide:

TJ has had some of his examples updated (and in the process of updating others) which I found a good helper to picking it back up
