Question 1

How do I include partials from different directories in Clostache?

Accepted Answer

Clostache supports partials via the optional third argument in render functions, but it relies on classpath resources. You need to ensure partial templates are accessible on the classpath, typically by placing them in resource directories and using `render-resource` for file-based templates.

Question 2

Clostache or Hiccup for Clojure web development?

Accepted Answer

Clostache is better for logic-less, specification-compliant templates that separate presentation from logic, while Hiccup uses Clojure data structures for HTML generation with more inline logic. Choose Clostache for cross-language templates or when strict logic separation is critical; Hiccup for more Clojure-native, programmatic approaches.

Question 3

How to escape JSON or other non-HTML content in Clostache templates?

Accepted Answer

Clostache automatically escapes HTML entities by default. For JSON or other formats, use unescaped tags like {{{ }}} or {{& }}, but you may need to pre-process data manually since it lacks built-in escaping for non-HTML contexts.

Question 4

Can I use Clostache with ClojureScript for front-end templating?

Accepted Answer

No, Clostache is designed for Clojure JVM and not compatible with ClojureScript. For front-end templating in ClojureScript, consider libraries like sablono or use JavaScript Mustache implementations directly.

Question 5

What's the performance impact for large datasets in Clostache?

Accepted Answer

Clostache renders templates efficiently for typical use cases, but for very large datasets or complex nested sections, performance might degrade due to lack of built-in caching. Optimizing data structures or preprocessing can help mitigate this.

Question 6

How to handle nested or deep data structures in Clostache?

Accepted Answer

Use dotted names (e.g., {{user.profile.name}}) to access nested variables directly, as shown in the README examples. This simplifies template syntax without requiring complex data flattening in Clojure code.
