"Can you tell me more about the purpose of $cacheFactory

Question

I am struggling to find information on the purpose and functionality of $cacheFactory in application development.

According to the Angular Documentation,

"Factory that constructs cache objects and gives access to them." -- $cacheFactory

However, this explanation does not provide much clarity. A search on Google also does not yield helpful results.

If anyone can offer insights into What it is & When it can be useful, I would greatly appreciate it.

Thank you in advance.

Answer 1

Answer №1

The concept of $cacheFactory is actually quite straightforward:

Imagine you have a scenario where you need to fetch static data, such as a list of cities.

It wouldn't make sense to always retrieve this list from the server whenever a user visits a form where they need to select a city!

That's where caching comes in handy, and the cacheFactory feature is designed specifically for this purpose.

If you're using $http instead of $resource, enabling caching is as simple as adding this line of code:

$http.get('myUrl', { cache: true })
