Okay I have a mostly static homepage but I wanted to have partial views that for navigation, footer ect. I\'m using ejs and it looks like this:
my controller: home.j
Partial was removed in 3.x. It's now up to the templating engine to provide partials.
As @Pickels said, Partial was removed in 3.x. However, the most recent version of EJS provides a mechanism for including "partials", called "include":
https://github.com/visionmedia/ejs#includes
Includes are relative to the template with the include statement, for example if you have "./views/users.ejs" and "./views/user/show.ejs" you would use <% include user/show %>. The included file(s) are literally included into the template, no IO is performed after compilation, thus local variables are available to these included templates.
The following will work as a replacement for your old partial() function. You'll need to make tweaks elsewhere to support Express 3.x completely, but for the most part this seems to work well (better actually - less code and more performant).
<% include nav.ejs %> <!-- replaces your old <%- partial('nav') %> -->
