Cache Plugin

This plugin injects a caching dynamic in a RocketJump.

The cache works in the following way

• when you instantiate a RocketJump, the cache is empty
• when you first call the load function, result is extracted and copied in the cache
• subsequent calls do not run the asynchronous effect, but directly resolve on the cached value
• you can force the cache to refresh by leveraging an ad-hoc action: loadForce

Use cases

You can use this plugin whenever your data are not expected to change or changes are very unfrequent with respect to the number of calls to the load action. The usage of a cache in this context greatly helps with performance by removing delays due to asynchronous jobs

Example

import rjCache from 'redux-rocketjump/plugins/cache'
// other code here...
const {
    actions: {
        load,
        loadForce,
    },
    reducer,
    selectors: {
        isLoading: isMyDataLoading,
        getData: getMyData,
        getError: getMyDataError
    },
    saga,
} = rj(
        rjCache,
        {
            type: 'MY_DATA',
            state: 'myData',
            api: fetchMyDataApi,
        }
    )()
