The runtime components for the jade templating language

Build Status Dependency Status NPM version


npm install jade-runtime


You can call runtime methods directly using runtime.method. This is particularly useful when compiling to deal with things that are already known at compile time.

var runtime = require('jade-runtime');
assert(runtime.attr('foo', 'bar', true, true) === ' foo="bar"');

You can also build a string with a given list of functions available as jade_method by calling build(arrayOfMethods). This is useful for inlining runtime functions within the compiled templates.

var build = require('jade-runtime/build');
var src = build(['attr']);
var attr = Function('', src + ';return jade_attr;')();
assert(attr('foo', 'bar', true, true) === ' foo="bar"');

When testing code compiled for the browser in Node.js, it is necessary to make the runtime available. To do so, one can use require('jade-runtime/wrap'):

var jade = require('jade');
var wrap = require('jade-runtime/wrap');
var jadeSrc = 'p= content';
// By default compileClient automatically embeds the needed runtime functions, 
// rendering this module useless. 
var compiledCode = jade.compileClient(jadeSrc, {
  externalRuntime: true
//=> 'function template (locals) { ... jade.escape() ... }' 
var templateFunc = wrap(compiledCode);
templateFunc({content: 'Hey!'});
//=> '<p>Hey!</p>' 
// Change template function name to 'heyTemplate' 
compiledCode = jade.compileClient(jadeSrc, {
  externalRuntime: true,
  name: 'heyTemplate'
//=> 'function heyTemplate (locals) { ... }' 
templateFunc = wrap(compiledCode, 'heyTemplate');
templateFunc({content: 'Hey!'});
//=> '<p>Hey!</p>'
