Lately I've been doing some restructuring on a site to improve
performance and was wondering if there is any overhead involved when
dynamically constructing a page from many smaller dynamic components
using 'includes' as opposed to having all the code in the same page.
(For example, a product list page has the product summary component
as an 'include' inside a loop).
There is overhead of course whenever you do an include. I usually stay
away from doing includes in a loop. In such cases I tend to put the
code in a library method. But if you don't expect many iterations of
the loop, don't worry too much about the overhead.
I've been using the fusebox naming conventions and structuring the
site as much as possible into fuseactions, circuits, fuses, display
code and layout code
My current convention is to have three subfolders within each circuit:
controller, model, and view. Business logic and non-DB actions go in
controller, database access goes in model, and display code goes in
view.
I thought that maybe Active 4D doesn't cache the included modules
(say, the way it does libraries) and so it might be slower for the
moment than a monolithic page where there are many iterations.
That is correct.
Also, what is the recommended way to pass properties set by a
fuseaction to a display component ? (for example, the
fuseaction . . . 'act_DoaQuery.a4d' . . . sets some properties and
the display component 'dsp_showCatalog' wants to read these
properties and modify it's own logic based on them. Is a collection
the way to do this ? Where is best to initialise it ?
It depends on what the properties are. If the data comes from the DB,
use a RowSet. If you have single properties, local variables are fine.
If you have a lot of data of various types, a collection is the
cleanest way.
