Consolidate.js

Template engine consolidation library.

Installation

$ npm install consolidate

Supported template engines

NOTE: you must still install the engines you wish to use, add them to your package.json dependencies.

API

All templates supported by this library may be rendered using the signature (path[, locals], callback) as shown below, which happens to be the signature that Express 3.x supports so any of these engines may be used within Express.

NOTE: All this example code uses cons.swig for the swig template engine. Replace swig with whatever templating you are using. For exmaple, use cons.hogan for hogan.js, cons.jade for jade, etc. console.log(cons) for the full list of identifiers.

var cons = require('consolidate');
cons.swig('views/page.html', { user: 'tobi' }, function(err, html){
  if (err) throw err;
  console.log(html);
});

Or without options / local variables:

var cons = require('consolidate');
cons.swig('views/page.html', function(err, html){
  if (err) throw err;
  console.log(html);
});

To dynamically pass the engine, simply use the subscript operator and a variable:

var cons = require('consolidate')
  , name = 'swig';

cons[name]('views/page.html', { user: 'tobi' }, function(err, html){
  if (err) throw err;
  console.log(html);
});

Caching

To enable caching simply pass { cache: true }. Engines may use this option to cache things reading the file contents, compiled Functions etc. Engines which do not support this may simply ignore it. All engines that consolidate.js implements I/O for will cache the file contents, ideal for production environments.

var cons = require('consolidate');
cons.swig('views/page.html', { user: 'tobi' }, function(err, html){
  if (err) throw err;
  console.log(html);
});

Express 3.x example

var express = require('express')
  , cons = require('consolidate')
  , app = express();

// assign the swig engine to .html files
app.engine('html', cons.swig);

// set .html as the default extension 
app.set('view engine', 'html');
app.set('views', __dirname + '/views');

var users = [];
users.push({ name: 'tobi' });
users.push({ name: 'loki' });
users.push({ name: 'jane' });

app.get('/', function(req, res){
  res.render('index', {
    title: 'Consolidate.js'
  });
});

app.get('/users', function(req, res){
  res.render('users', {
    title: 'Users',
    users: users
  });
});

app.listen(3000);
console.log('Express server listening on port 3000');
