EJS2
EJS2 is a reimplementation of visionmedia's EJS node module. A fair amount of code is copied straight over, but improvements have been made.
It's built to use async functions (as in, readFile with callbacks rather than readFileSync) and to have more maintainable code. It also makes it more extensible as async functions can be added in (which will help with rendering in serenity).
Usage
Pretty much the same as the original, one or two changes.
var EJS = require('ejs2');
var ejs = new EJS({ cache: true }); // cache is enabled by default, equivalent is just `var ejs = new EJS();`
ejs.render('i am an EJS string', {opts: 'go here'}, function(err, html) {
// you have html!
});
ejs.renderFile('/my/ejs/file.ejs', {opts: 'still go here'}, function(err, html) {
// you have more html!
});
Benchmarks
For some strange reason, the original EJS is faster with the cache disabled (I assume readFileSync is slightly faster, but of course it's bad practise and blocks the process). EJS2 is slightly faster with the cache enabled. The differences are up to a couple of hundredths of a millisecond. Running the benchmarks on different file types would help, as I believe EJS2 will be quicker when there are includes in the file.
