Caching

Often times data doesn't change that quickly, especially in the case of rolling up corporate news or upcoming events. These types of things can be cached for minutes if not hours. To help make caching easy you just need to insert the usingCaching method in your chain. This only applies to get requests.

Basic example

You can use the method without any additional configuration. We have made some default choices for you and will discuss ways to override them later. The below code will get the items from the list, first checking the cache for the value. You can also use it with OData operators such as top and orderBy. The usingCaching() should always be the last method in the chain before the get() (OR if you are using batching these methods can be transposed, more details below).

pnp.sp.web.lists.getByTitle("Tasks").items.usingCaching().get().then(r => {
    console.log(r)
});

pnp.sp.web.lists.getByTitle("Tasks").items.top(5).orderBy("Modified").usingCaching().get().then(r => {
    console.log(r)
});
