preducs

Tiny library to manage your application state. It supports interceptors(modifiers) to handle and modify data on the fly.

How to use it

Check out the tests folder for usages, but this is the common usage.

import createStore from 'preducs';
 
// Create the store
let store = createStore({
    loading: true // Your data
});
 
// Subscribe to updates
let unsubscribe = store.subscribeToUpdates((state) => {
    console.log('I got updated', state);
    
    // Unsubscribe the current listener
    unsubscribe();
});
 
// Update the store, with a call to a api
store.update({
    loading: false
}, (currentState, newState) => {
    return fetch('/api/endpoint')
        .then(res => {
            return {
                ...newState,
                ...res.json()
            }
        });
});
 

And that's about it!
