JADE: Sirviendo recursos específicos de la ruta

Question

En mi ./inc/footer.jade, tengo un montón de etiquetas de script.Me gustaría servir script adicional solo en una ruta específica. ¿Cómo lograr esto?

en los controladores que podría hacer:

res.render('someTemplate', {
  extraScript: true
});

y en footer.jade

- if (extraScript)
  <script src="/script.js"></script>

Pero entonces tendría que incluir esta variable 'extrascript' en cada ruta (se establece en falso).

Answer 1

You can use typeof to check whether a variable exists.

- if (typeof extraScript !== 'undefined')
  <script src="/script.js"></script>

In this way, for all the routes that do not need the additional script, you simply don't pass in extraScript, and then in the template, typeof extraScript !== undefined will be evaluated to false.

Answer 2

The extraScript solution works, but I believe a better solution would be to use template inheritance (block and extends keywords) . This way you don't have to add logic and a local variable to your templates, and you can still keep things DRY in your jade markup.
