Question 1

How do I use JavaScript Templates with Node.js?

Accepted Answer

Install via npm (blueimp-tmpl), require the module, and override tmpl.load to read template files. The README provides a full server example with HTTP response rendering.

Question 2

JavaScript Templates vs Handlebars: which is better?

Accepted Answer

JavaScript Templates is lighter and faster with zero dependencies, but Handlebars offers a more declarative syntax and richer helpers. Choose based on whether you prioritize minimalism or expressive templates.

Question 3

How can I precompile templates for better performance?

Accepted Answer

Use the included Node.js tool (tmpl.js) to compile templates into optimized JavaScript code. Run it via command line, and it outputs a combined file with cached templates for faster rendering.

Question 4

Is JavaScript Templates safe from XSS attacks?

Accepted Answer

Yes, by default it escapes HTML special characters with tmpl.encode, but you can customize encoding via tmpl.encReg and tmpl.encMap. Always use interpolation ({%=...%}) for untrusted data.

Question 5

How to include one template inside another?

Accepted Answer

Use the include() helper function within templates, passing the template id and data object. The API section shows how to define and use helper variables for this purpose.

Question 6

Can I change the data parameter from 'o' to something else?

Accepted Answer

Yes, override tmpl.arg to rename the parameter. For example, set tmpl.arg = 'data' to use {%=data.title%} instead, as documented in the template function argument section.
