ember-data-store-cache

Provides ability to use a minimum required cache time on Ember Data requests.

Currently works only on findAll type finds. findById already uses the data in the store. findQuery isn't supported yet.

Installation

• ember install:addon ember-data-store-cache
• ember install ember-data-store-cache ( ember cli ^0.2.3 )

Usage

Basic Usage

• Add file store.js to the app directory and extend DS.Store with the ember-data-store-cache mixin.

import DS from 'ember-data';
import CacheMixin from 'ember-data-store-cache/mixins/ember-data-store-cache';

export default DS.Store.extend(CacheMixin, {
});

• Where you want to require a mandatory minumum cache time, use findWithCache instead of find.

// Find all users. Use what's in the store if find has already been done within
// minimum cache time.
model: function() {
    return this.store.findWithCache('user');
}

// Find all users then filter client-side for users with requested company ID.
beforeModel: function() {
    return this.store.findWithCache('user');
},

model: function() {
    var company = this.modelFor('companies.read');
    return this.store.filter('user', function(user) {
        return user.get('company.id') === company.get('id');
    });
}

Customizations

Default Cache Minimum

• Default cache minimum is 10 minutes. To override, set the property cacheSeconds in store.js.

import DS from 'ember-data';
import CacheMixin from 'ember-data-store-cache/mixins/ember-data-store-cache';

export default DS.Store.extend(CacheMixin, {
    cacheSeconds: 120
});

Cache Minimum per Request

• To specify the cache time per request, pass cacheTime parameter to findWithCache as the number of seconds to cache.

model: function() {
    return this.store.findWithCache('user', null, null, 300);
}

Clearing cache

There are 2 methods to clearing the cache.

• clearCache: Remove all entries of typeKey from the store and reset the metadata cache time so the next request via findWithCache will make the request to the server.
• clearCacheTime: Reset the cache time for time to null so the next request via findWithCache will make the request to the server.
