Basic questions about FF

[Ben]

Hello,

I have some basic questions concerning this interesting framework:

- Can it be used as an API to return responses in JSON format ?

- How slower is it to use the built in template engine, instead of PHP templates ?

Hello,

Hi there!

 

- Can it be used as an API to return responses in JSON format ?

Sure can! See ReST routing info here and a xml template example here (You can use the same method for json by changing the mime type if you really want to go the template route for json)

 

- How slower is it to use the built in template engine, instead of PHP templates ?

Probably a few microseconds slower as expected for each new layer of abstraction.

Also, if you're just outputting json, you can always just do something like this from your controller or afterroute:

header('Content-Type: application/json');
echo json_encode($myapidata);

And skip templating entirely.

I hate seeing these questions "How slower is it..."

Performance should be an after thought until the project actually gets done. Especially with a framework like F3 that is already crazy fast.

Since F3 is converting its own templates to pure PHP templates, you won’t feel any difference in my opinion. If you care about database related benchmarks though check out
