![]() ![]() ![]() We really hope this changes the way developers look at building not just Backbone applications but web applications overall. This allows business logic to lay in more places than one. This is also much more extensible since any client or server can listen to the events and manipulate them as they need to. Instead, with PubNub integration, your users will get data right when it happens. Your users will not have to click a refresh button to constantly synchronize their Backbone client data with a server. A collection listens to the events fired. We here at PubNub truly believe that real-time is the way of the future. A collection includes functionality to add, remove, sort, and filter models, and save to or fetch data from the server. backbone Best JavaScript code snippets using backbone.Collection(Showing top 10 results out of 315) Most used backbone. You can use these endpoints as-is to read, update, create and delete items using standard Backbone methods (fetch, sync, save & destroy for models, sync for. This is just one easy way to use the framework but be sure to check out the repository for more examples! Wrapping Up Backbone Although nodejs was an obvious choice for the demo, this code will work with any type of back end too. You can even add other business logic for validations and more. Now you can listen for all the changes to the collection and either store them in memory or even a database such as MongoDB. This is made even simpler when using the backbone npm module for nodejs: Then the client can ask for the current set of data every time the application loads. A great way of accomplishing this is by listening to the PubNub based events with a server and replicating the data store. The next step is to implement a way to get the current set of data when the collection first loads so every client is using the same data set. You can listen for add and remove events just like usual when something gets added or removed in real time. Parameters: models: This parameter is used to specify the models to be removed from the collection. ![]() Now your Backbone collection will update in real time. JS Remove() collection method removes a model or array of models from a collection. This is the object that comes back after calling PUBNUB.init. The “pubnub” property is the globally referenced connection to the PubNub network. It uses this to generate a PubNub channel that is unique to the collection in the form of “backbone-collection-”. Think of this as a namespace so you can have multiple types of collections all updating in real time. The “name” key allows PubNub to distinguish this collection, so it connects this collections to only collections of the same type. This will look and act just like a normal Backbone collection with two extra keys. Now that we have a connection to PubNub, we can feed that connection into our custom Backbone collection: Once you have, clone the GitHub repository, and enter your unique PubNub keys on the PubNub initialization: Once you sign up, you can get your unique PubNub keys in the PubNub Developer Portal. This will automatically propagate all create, update, and delete methods across all other clients in real time. You’ll first need to sign up for a PubNub account. The easiest way to get started using the library is by creating a PubNub based collection. Now you can include this and the base PubNub library found at like so: You can also clone the repository and copy the built javascript files. The easiest way to get started is by using bower via “bower install pubnub-backbone”. You’ll first need to sign up for a PubNub account. Want to see it in action? A full working tutorial and all the code you need is available here. It works by taking all of the create, update, and delete methods that are spawned by Backbone and propagating them across the PubNub Data Stream Network. This will give any Backbone application a better user experience when working with collaborative, social, or any type of multi-user interface. Our integration allows developers to create a Backbone model or collection and have them synchronize with every other client instance of those models or collections in real time. ![]() Instead of having to constantly synchronize data between your client and server though, why not have all the data there when it happens? Users should not have to wait to see updates to their model’s data so we decided to tackle this problem by integrating Backbone.js with PubNub. It is a simple yet powerful way to create interactive JavaScript applications with data bindings to a back-end server. I tried people.Backbone is one of the most popular JavaScript based frameworks to date. How do I remove remove a model in collection and make the remove event fire. ![]()
