Re: Should I use Django-Rest-Framework for performance reasons, despite not needing an externally-consumable API?

Hi,

Using DRF can help when there is a need for decoupling the presentation layer from the logic one, for instance if the logic is planned to be used in other scenarios that the interactive Web app.

One can argue that structuring the logic as a Python package can do it, but this will not work if the deployment involves splitting front-end and logic back-end in distinct nodes (f.i. in a Docker multi-container based deployment).

Introducing DRF adds for sure a level of complexity and you'll loose some potential caching benefits, but it lets the path opened if ever the above mentioned evolution of the application appears in the future. You will not have to refactor anything then.

The bottom line is that there is no absolute answer to the question. It depends on what can be the plans for the application evolutions in the future.

Regards

Eric

Hi,

I really don't get why you would want to do that? If you are doing only a "standard" website - you don't want or NEED the extra complexity of running DRF. It's not that DRF is hard to setup - but for example if you want to present a list of items - in "standard" django, you create the list and add it to the context data. In DRF - you need to create the list, serialize it into json (or xml if you want to go that route), on the frontend you then need to deserialize the list and present it.

You add a lot of complexity and need to write a lot of frontend code.

Working with "standard" django - you can cache a lot of things in different places. You can for example cache an entire response with template, or just cache the database calls and present them in a template. This is not hard to cache or to setup. 

I think I would need to know more about your use case to understand it better :-)

Regards,

Andréas

I have no need for an externally consumable API, but I am interested in using Django-Rest-Framework simply for performance reasons. 

I'm led to believe that by decoupling my front and back end and then simply consuming the DRF api within views, that I can setup a better caching system? Does this make sense? Using DRF from an architectural standpoint (with the goal of optimizing caching & performance) despite not needing an externally used API? Or am I totally off base and confused? Any advice would be much appreciated.
