Filter-observable-store

Filter down an observable store https://github.com/flams/observable-store.

A filtered observable-store will:

• Return a count of items that match the filter
• Only loop over items that match the filter
• Only trigger events on items that match the filter

Installation

npm install filter-observable-store

How to use

var Store = require("observable-store");
var Filter = require("filter-observable-store");

var store = new Store([5, 10, 15]);

// Create a new filter around an existing store
var filter = new Filter(store);


// Set a filter function
filter.setFilter(function (value) {
    return value >= 10;
}, scope);

// Get filtered count:
filter.count(); // 2

// Loop over filtered items
filter.loop(function (value) {
    // value... 10, 15...
});

// See if an item is in the filtered model
filter.has(5); // false
filter.has(10); // true

// Clear filter
filter.clearFilter();
