Question

Is it possible to load assets conditionally with Assetic?

For example (peusocode):

load resource1.js
load resource2.js

if condition = true
    load resource3.js
endif

output combined.js

Answer 1

No it’s not possible because assetic files are compiled on the server side, so assetic don’t have access to the value of your variable at runtime.

A solution could be to add a second assetic tag

// the first assetic tag

{% if condition %}
    // an other assetic tag
{% endif %}
