Would it benefit to pre-compile jade templates on production in express

Question

When using jade-lang on production, would I benefit from having some form of a middleware that pre-compiles all the .jade views and then uses them in res.render? Or does tha

Answer 1

When Jade compiles the template, the template is cached. In production environment if you warm up the cache, then there is no need to pre-compile template. Even if you don't, the template will be cached after its first compilation.

I recommend you to have a look Jade's source code to better understand how it works.

exports.render = function(str, options, fn){
  // ...
  var path = options.filename;
  var tmpl = options.cache
    ? exports.cache[path] || (exports.cache[path] = exports.compile(str, options))
    : exports.compile(str, options);
  return tmpl(options);
};

exports.renderFile = function(path, options, fn){
  // ...
  options.filename = path;
  var str = options.cache
    ? exports.cache[key] || (exports.cache[key] = fs.readFileSync(path, 'utf8'))
    : fs.readFileSync(path, 'utf8');
  return exports.render(str, options);
};
