Jade Question

Is it considered bad practise to use HTML in Jade?

Jade looks like a cool templating engine and I think I'll be using it for my next project. However, some of the syntax doesn't make sense to me.

What do you get by doing this:

a(href="#book-a") Book A

instead of:

<li><a href="#book-a">Book A</a></li>

I understand you save some typing, but it seems less readable to me. I noticed on Jade's live demo that regular html passes right through the translation. So would it be considered bad practise to do something like this:

<div class="someClass">
<h3> #{book.name} </h3>

Actually jade syntax allows plain HTML (or any other plain text) through the use of 3 syntaxes, as you can see in the reference on the project's site.

dot syntax (also known as "Block in a Tag")

  <li><a href="#book-a">Book A</a></li>
  <li><a href="#book-b">Book B</a></li>

pipe syntax (also known as "Piped Text")

  | <li><a href="#book-a">Book A</a></li>
  | <li><a href="#book-b">Book B</a></li>

tag syntax (also know as "Inline in a Tag"), "Simply place some content after the tag", can also do the trick

  li <a href="#book-a">Book A</a>

which will render

<ul><li><a href="#book-a">Book A</a></li></ul>

The Question

Back to your question, your sample

<div class="someClass">    
  <h3> #{book.name} </h3>

could be written as simple as

  h3= book.name

Which is a lot more readable I think, so in that case you should consider a bad practice writing raw HTML, but not always.


IMO, common sense is the best good practice. Maybe i would consider using a raw chunk of HTML to insert a widget on the page, i.e. a youtube video or a custom google map <iframe>.

<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="https://maps.google.es/maps/ms?msa=0&amp;msid=217708588685721440865.0004d1d4faefdd11adf39&amp;ie=UTF8&amp;ll=43.167638,-7.838262&amp;spn=1.010793,0.991384&amp;t=m&amp;output=embed"></iframe>

<iframe width="420" height="315" src="http://www.youtube.com/embed/_Vkm2nMM3-Q" frameborder="0" allowfullscreen></iframe>

As said above, here doesn't makes sense to use the attribute syntax. The result is nearly the same, and is quicker leaving the raw html.

iframe(width="425", height="350", frameborder="0", scrolling="no", marginheight="0", marginwidth="0" src="https://maps.google.es/maps/ms?msa=0&amp;msid=217708588685721440865.0004d1d4faefdd11adf39&amp;ie=UTF8&amp;ll=43.167638,-7.838262&amp;spn=1.010793,0.991384&amp;t=m&amp;output=embed")

iframe(width="420", height="315", src="http://www.youtube.com/embed/_Vkm2nMM3-Q", frameborder="0", allowfullscreen)
