I want to pass my variables into that template, let it render, and then get the resulting HTML as a string.
How can I do that in Express?
Depending on the ejs version the following should work.
var ejs = require('ejs'),
fs = require('fs'),
file = fs.readFileSync(__dirname + '/template.ejs', 'ascii'),
rendered = ejs.render(file, { locals: { items:[1,2,3] } });
console.log(rendered);
You may need to install ejs if it isn't already installed.
cd;npm install ejs
