Meteor persistent minimongo

It seems that frozeman/meteor-persistent-minimongo2 is unmaintained.

Simple client-side observer class that provides persistence for Meteor Collections using browser storage via localforage.

localforage uses the browsers indexedDB, if not available tries webSQL and as last option uses localstorage.

Documentation

Constructor

new PersistentMinimongo2(collection, 'myAppName');

collection is the Meteor Collection to be persisted.

The last parameter is the apps name and should be used to identifiy your persisted collections inside your storage. Default is minimongo

Methods:

var myPersistentCollection = new PersistentMinimongo2(collection, 'myAppName', afterInitialisationCallback);

// Refreshes the collections from the storage
myPersistentCollection.refresh()

// If you ever need to clear you storage use
localforage.clear();

// The below is only interesting if your brower doesn't support indexedDB or webSQL:
// Gets the current size of the localstorage in MB
myPersistentCollection.localStorageSize()

// Will check if the current size of the localstorage is larger then 4.8 MB, if so it will remove the 50 latest entries of the collection.
myPersistentCollection.capCollection()

Example:

Implement a simple shopping cart as a local collection.

if (Meteor.isClient) {
    // create a local collection,
    var shoppingCart = new Meteor.Collection('shopping-cart', null);

    // create a local persistence observer
    var shoppingCartObserver = new PersistentMinimongo2(shoppingCart, 'myShoppingApp');

    // create a handlebars helper to fetch the data
    Template.registerHelper("shoppingCartItems", function () {
      return shoppingCart.find();
    });

    // that's it. just use the collection normally and the observer
    // will keep it sync'd to browser storage. the data will be stored
    // back into the collection when returning to the app (depending,
    // of course, on availability of localStorage in the browser).

    shoppingCart.insert({ item: 'DMB-01', desc: 'Discover Meteor Book', quantity: 1 });
  });
}
