Algorithm to register all handlebars partials at once on an express server.

app.js

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var routes = require('./routes/index');
var users = require('./routes/users');
var hbs = require('hbs');
var fs = require('fs');

// ... stuff omitted for brevity


// Register Handlebars Partials
var partialsDir = __dirname + '/views/partials';
var filenames = fs.readdirSync(partialsDir);

filenames.forEach(function(filename) {
    var matches = /^([^.]+).hbs$/.exec(filename);
    if (!matches) {
        return;
    }
    var name = matches[1];
    var template = fs.readFileSync(partialsDir + '/' + filename, 'utf8');
    hbs.registerPartial(name, template);
});
