[TYPO3-mvc] eID, extbase, ajaxDispatcher, template not found

Tue Jul 1 14:50:49 CEST 2014

Hey there.

I completely agree with Helmut.
eID can be really fast if you skip almost everything except e.g. database.

But as soon you need a tiny TYPO3 core feature, chances are that you end up with booting a nearly complete TYPO3 environment.

Think about e.g. TypoLink. There is no TypoLink without current TypoScript configuration and TSFE with loaded TSFE->id. There are many reasons for this, an obvious one is mount points.

TypoScript itself. It depends on various things, like e.g. frontend users and calculated user groups of frontend users. Just go through every available condition TypoScript has, like treelevel, TSFE:*, PidInRootline or usergroup. Everything needs to be calculated and available, just to even decide if the TypoScript is already available as cached array or needs to be parsed entirely.

Or any output for different languages. Language overlay records, overlay xlif or ll-xml files. It's a real paint to consider all of that yourself, so you most likely end up starting TSFE with an L argument.

Again: eID can be superfast and is awesome if it's a real low level task you want to do.
But as soon as you need a slightly advanced core feature you need to initialize just as much of TYPO3 as you get when using a dedicated page type or Helmuts extension.

Hi!

But it comes from cache after the first hit.

If the action itself isn't cachable, it does not mean that the rest cannot be cached.

Did you measure the overhead here? It was pretty low during my tests.

Same here. Instantiating classes is pretty cheap.

Will be cached after first hit.

Well, if you need to call an Exbase action via Ajax, then this is of course a price you have to pay.

Same here.

I know :)

Well, yes of course.

True. If you need to optimize that much or have a simple case where you do not need anything but a DB connection or a simple FE user, eID is the way to go; sure!

But *if* you need a page (TSFE) or even TypoScript, bootstrapping all this in your eID script is hard to get right. You end up with C&P almost all of the code in TSFE, which at best slows down your request to a regular page request level which never will be cached (so it is slow for every request), at worst you end up with broken code that will also break regular requests (as wrong things could get cached for your page).

Summary:
* Easy code with no dependencies: eID
* "Normal" code with dependencies to TypoScript: typoscript_rendering[1]

:)

Kind regards,
Helmut
