Plugins

Plugins for stash-it are things that can influence the data that flows through cache instance's methods. Plugins can also add new functionality (extend the API).

A plugin is an object that consists of, at least, one property: hooks and / or createExtensions. Here is an example of full grown plugin (without the body):
{
    hooks: [],
    createExtensions: ({ cacheInstance, getPreData, getPostData }) => {}
}
How to use a plugin? What do I get from it?
If you take for example stash-it-plugin-debug you gain two things (read more on this plugin's repo page):
Data that flows in, through and out of each cache's method is going to be tracked (using passed callback, e.g. console.log).
Adds new method runDiangnostics().
Here's how you use it:
import createDebugPlugin from 'stash-it-plugin-debug';
​
// assuming that you already have cache instance
const debugPlugin = createDebugPlugin(console.log);
const cacheWithPlugins = cache.registerPlugins([ debugPlugin ]);
​
// without the plugin, this method would not be here
cacheWithPlugins.runDiagnostics(); // runs the diagnostics
​
cache.runDiagnostics(); // error, runDiagnostics is not a function
