using default value with an ejs filter

If item.description is undefined or empty, I want to default to 'No description':

I've tried the following:

  <%-: ( item.description | markdown ) || '<p>No description</p>' %>
  <%-: ( item.description || 'No description' ) | markdown %>

What else can I do?

I'm wondering the code with your question, why the pre-tag with ejs template expression is "<%-" not the "<%=" (the output or value assignment output) or the "<%=:" (the filter output) signature?

BTW, the filter invoke signature is the single vertical bar not double, and you can invoke any times with what you want...

Not sure if you can mix || with the | of EJS' filters, but you can add a filter to accomplish it:

ejs.filters.or = function (arg, sub) {
  return arg || sub;
};

<%-: item.description | or:'No description' | markdown %>
