Answer 1

Here's a very simple example on how app.locals can be used to expose variables to (EJS) templates:

// app.js
var express = require('express');
var app     = express();
var server  = app.listen(3000);

app.locals.myVar = 1;

app.get('/', function(req, res) {
  res.render('index.ejs');
});

// views/index.ejs
<% if (myVar) { %>
  
myVar is here!
<% } else { %>
  
Boohiss no myVar!
<% } %>
