Squirrelly is a modern, configurable, and blazing fast template engine implemented in JavaScript. It works out of the box with ExpressJS and weighs only 2.6KB gzipped.

Why Squirrelly?


  • Custom helpers
  • Custom filters
  • Conditionals
  • Loops
  • Custom delimeters
  • Precompilation
  • Partials
  • Writing JavaScript inside the template
  • Comments
  • Caching
  • Just look at the performance benchmarks here


We know nobody reads through the long and boring documentation in the ReadMe anyway, so head over to the documentation website:


Simple Template

var myTemplate = "<p>My favorite kind of cake is: {{favoriteCake}}</p>"
Sqrl.Render(myTemplate, {favoriteCake: 'Chocolate!'})
// Returns: '<p>My favorite kind of cake is: Chocolate!</p>


{{if(options.somevalue === 1)}}
Display this
Display this


Display this
The current array element is {{@this}}
The current index is {{@index}}


The default test can be run with npm test, and it just checks that compiling and rendering a simple template results in the correct string.
