Liquid-Node is a promise-based template language which is useful to create templates after async database calls (amongst other things). There isn't in-built support for ExpressJS.
What is the best way of getting Express to use Liquid-Node as its view engine?
The best I've come up with uses vow-fs for fs promises (in Livescript), and assumes views are called with the extension '.liquid':
vowfs = require \vow-fs
Liquid = require \liquid-node
app.engine \.liquid, (filename, options, fn) ->
vowfs.read filename
.then (res) ->
content = res.toString!
template = Liquid.Template.parse content
template.render options
.then (res) -> fn null, res
