A middleware that will use the views path and the view engine string that are stored against an Express app object to generate a key-value object that identifies and makes accessible the file paths of partial templates against res.locals.partials on execution.
npm install [--save] express-partial-templates;
var app = require('express')();
app.set('view engine', 'html');
app.set('views', path.join(__dirname, '/views'));
app.use(require('express-partial-templates')(app));
app.use(function (req, res, next) {
// res.locals.partials has been set.
next();
});
