As a software consultant, I get to see a lot of interesting code. In this particular instance a client was in the process of transforming their web application to a rich, interactive interface with the help of another company.
The project kicked off using Backbone and things were great. Until they were not great. Pages starting getting more and more involved and blame started being thrown at the technology choice.
A move to Ember.js ensued and the app was rewritten. But architecturally bad decisions don't hide long, and soon the rewrite was preforming even worse. That's when I stepped in, with the help of another consultant, to solve the performance issues once and for all. Our solution used Backbone.js and it was fast. This is that journey.
Javascript Frameworks for Well Architected, Immersive Web Appsdnelson-cs
Immersive web applications involve sophisticated interactivity within the browser, connected to models and data persistence on the server. The structure of the application is clearly delimited between client-side and server-side, but the available tools for building web applications have often blurred this distinction. The result is applications that are difficult to design and maintain.
This presentation is an effort to combine all the cool features present in Angular and provide a basic idea about how it would help a developer overcome some of the common issues faced in client side development.
The document provides an overview of AngularJS, including its core concepts and how it can be used with Java frameworks like Spring, Struts, and Hibernate. AngularJS is an open-source JavaScript framework that assists with building single-page applications using MVC architecture. It allows developers to specify custom HTML tags and directives to control element behavior. The document then discusses key AngularJS concepts like data binding, directives, expressions, filters, controllers, dependency injection, views/routing, and services. It provides examples of how these concepts work and how AngularJS can integrate with Java frameworks in a sample reader application divided into multiple sub-projects.
What is AngularJS
AngularJS main components
View / Controller / Module / Scope
Scope Inheritance.
Two way data binding
$watch / $digest / $apply
Dirty Checking
DI - Dependence Injection
$provider vs $factory vs $service
In a world of emerging JavaScript, is Rails getting left behind? Are server-side MVC applications out and static single page applications in? In this talk I’ll describe how we’ve used webpack(er) and Vue to revitalize our JavaScript approach within an aging Rails application. You can have it both ways.
AngularJS is an open-source JavaScript framework that assists with building single-page applications using Model-View-Controller architecture. It uses two-way data binding between models and views, and its directives and filters help manipulate DOM elements and format data for display. AngularJS implements dependency injection to modularize code and make components reusable. Scopes in AngularJS act as containers for models and facilitate inheritance between parent and child scopes.

Refactoring Large Web Applications with Backbone.jsStacy London
Have you ever starting working on a large, existing web application and jQuery spaghetti-code is all over the place? Your mind swirls as you try to figure out what code belongs to what component on what page. There are no JavaScript unit tests and you're terrified of making a change and breaking everything? I'm going to talk through the real life story of how Backbone.js helped to bring organization/structure, modularity, and testability to a large multi-page web application.
The document describes refactoring a large web application with JavaScript from a messy state to using Backbone.js and a modular structure. It was refactored iteratively over several sprints. Key changes included breaking the JS into separate page-specific files, adding namespacing, using Backbone views to modularize code, moving to a model-view pattern, and finally implementing a module system using RequireJS and Browserify for dependency management and bundling. This resulted in code that was better organized, testable, and maintainable.

Introducing Rendr: Run your Backbone.js apps on the client and serverSpike Brehm
Rendr is a JavaScript library that allows Backbone.js applications to run on both the client and server sides. It provides common classes and logic that can be reused across both environments, such as BaseView, BaseModel, and routers. On the server, it renders the HTML output using the same application logic. On the client, it hydrates the views by attaching them to the corresponding DOM elements. The goal is to write application logic in a way that is agnostic to the environment, avoiding duplicating code or context switching between client and server implementations.

This document discusses the development of rich internet applications with ASP.NET. It provides an overview of technologies like Knockout, ASP.NET Web API, HTML5, and SignalR that enable building single page applications with client-side rendering. Knockout uses data binding and the observer pattern to update the DOM based on view model changes. The ASP.NET Web API builds on MVC to provide RESTful services that return JSON/XML data rather than views. HTML5 features like client-side validation, web storage, and Web Sockets improve the client-side experience. SignalR uses WebSockets for real-time communication between server and client.
1. Backbone.js is a lightweight JavaScript framework that brings structure to client-side code through an MVC pattern.
2. It separates presentation logic from business logic by defining Models, Collections, and Views. Models represent data, Collections hold lists of Models, and Views render the UI and handle events.
3. While Backbone.js allows building single page applications quickly, code can become disorganized without its structure. The framework encourages maintainable, loosely coupled code through its MVC implementation.
1) The document discusses how to build modular web applications using the JavaScript frameworks Backbone.js and RequireJS. It advocates separating an application into reusable components using the Model-View-Controller (MVC) pattern and composing the interface from independent views.
2) RequireJS allows code to be split into bite-sized modules and defines dependencies between modules. This supports large-scale application development and avoids dependency issues.
3) The document provides an example of a fictitious stock trading application called Bullsfirst that demonstrates these techniques and emphasizes the importance of architecture for engaging web applications.
Ember is an open source JavaScript framework that uses a strict MVC pattern. It avoids boilerplate code and creates standard application architecture. Ember follows a pure MVC pattern to improve testability and keep application code modular.

Alluxio Webinar | 10x Faster Trino Queries on Your Data PlatformAlluxio, Inc.
Alluxio Webinar
June. 18, 2024
For more Alluxio Events: https://www.alluxio.io/events/
Speaker:
- Jianjian Xie (Staff Software Engineer, Alluxio)
As Trino users increasingly rely on cloud object storage for retrieving data, speed and cloud cost have become major challenges. The separation of compute and storage creates latency challenges when querying datasets; scanning data between storage and compute tiers becomes I/O bound. On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache
- Real-world cases, including a large online payment firm and a top ridesharing company
- The future roadmap of Trino file system cache and Trino-Alluxio integration

33. : Issues
• very opinionated, very large codebase
• does black magic with Handlebars
• assumes you need the big guns
• two-way data binding by default
• easy to shoot yourself in the foot
42. People Problem
• lack of knowledge in front-end technologies
• not enough pairing and information sharing
• team skill level was not adequate to pick up where
Vendor Co. left off
• amount of documentation was lacking
43. Our Solution
• focus on knowledge sharing
• pair programming / technical side projects
• build what the client understands
• built JS workflow with the client’s help
• explicit code, no magic
• uses CommonJS and Browserify
• use technologies with little change and a wealth of
documentation

53. My Challenge
• build apps with
production data in
mind
• consider non-technical
needs of project
• show love for all
technology choices,
but be hesitant to
adopt new libraries
Time Machine: my cohort, Eric Browning, is talking about “No More Static Comps: Design Process in the Modern World” at 11am in Salon D.
I’m a consultant that gets to work with lots of different clients and I get to write (and see) a lot of different code. To keep it professional, no names in presentation or during questions besides my own.
Most programmers get paid to write code. They work on different projects.
I get paid to work on MANY different projects. Get to see a lot of good/bad practices, work in different languages, solve different problems. I can bring unique perspective to projects.
Client = Widget Factory
if you haven’t guessed, no real names please
Widget Factory hired Vendor Co to build a web application. A dashboard. Many moving pieces / parts. We will focus on front-end UI.
* show latest numbers from server
* chart shows historical numbers over past X hours
* data loaded when app loads and polls every X seconds
data from API server was in bloated format
adding features felt like it was taking too much time
there was some code pairing and information sharing to help bridge gap
everyone had best intentions in mind
best intentions in mind
Ember has easy data binding, easily update views when data updates
I used Backbone in many projects before, comfortable
laughable, does not provide much in terms of “structure”
organizes jQuery spaghetti code (still useful)
the “M” in MVC, organization of data
JS Objects and Arrays with enumeration management methods
utilize events for having app adapt to changes in state
uniform way to manage DOM events and create custom events
logic to map data and state changes to what the user sees and interacts with
ends up doing most of the work
* views have events as well, no biggie nowadays but useful for separation of responsibility
pushes JSON out of the box
can be customized, but it can be painful and require a lot of custom code
opinionated collection of “best practices”
does a lot of the grunt work for you
* created to tackle complicated web applications
(highlight parts of the definition giving a real explanation of what that means for the developer)
* same as Backbone and most front-end “frameworks”
this is where Ember truly shines
directional team very interested in providing best of breed, open to changing technologies
start to build relationships between data
separate library called Ember.data that handles async data retrieval
Backbone all manual, Ember is automatic
router gets quite a bit of praise
much more powerful than Backbones, handles tiers of triggered controllers (nice if your app plays well with well structured urls)
I’m not used to it yet
surprised to see conversations of Rails bloat, but flocking to Ember
two way data binding by default produces unnecessary overhead
follows Rails, easy to write code, also easy to not know what you wrote (how much computation behind the scenes?)
app still suffered from two big issues
* original app looked great with 10 - 20 items
* needed to show more than 500, also limited by other architecture choices
load all the dataz!
write less code, bind more things
render it all
Comparing Backbone w/Marionette to Vendor Co’s
took TodoMVC app and “productionized” assets to take performance numbers
I downloaded TodoMVC examples and got line counts
what I believe was the biggest issue with Vendor Co’s app
Widget Factory can’t maintain something they don’t understand
they would have been disappointed in any solution they received
* technical solution delivered that did not account for non-technical project needs
* how often things broke in lib or architectural decisions
* keyword is “our”, built entire structure with assistance from Widget Factory employees
* discuss how our solution addressed non-technical needs of project
* team uplift / pairing
* designing a workflow together
* explicit code rather than implicit magic
* amount (and quality) of documentation for js libs and css framework (bootstrap)
abstracted JS workflow into common Grunt library
abstracted common application system and code into common UI library
this will create a Layout based on your application’s main layout
you “export” what you want other files to be able to require
all dependencies must be required
Browserify handles dependency management
all source is concatenated into one js file (automatically skips unused source code)
built upon Backbone and
Backbone.Wreqr (messaging patterns for Backbone apps)
Backbone.BabySitter (manage child views)
* Wreqr changing to Backbone Radio in upcoming release of Marionette
removes the copy/paste boilerplate for view rendering from Backbone
bringing design patterns into Backbone:
Application singleton
module loader
view hierarchies
view behaviors (sectioned responsibilities for a single view)
template caching
view regions / region managers
view hierarchies
ItemView, LayoutView, CollectionView, CompositeView
Regions and RegionManagers
Backbone.Wreqr / Radio that uses channels (ex: “global”)
commands (do something, don’t care about response)
event aggregator (custom events attached to your application)
request / response (return data from request)
My challege to all of you
consider non-technical needs or else miss expectations on delivery
hesitate to introduce new technologies to solve the problem
think about the REAL problems and what it takes to solve them, do not focus on only technical problems
