DESCRIPTION
At Ally, we used Node.js along with Grunt, Yo and Bower to develop a custom developer toolset for Ally's front-end development teams. The toolset had to be crafted in a way that allowed us to take a forward approach while still supporting the use of some legacy code and not-so legacy code. In the end, we created a toolset that separated new and on-going development tasks, gave living documentation and usage examples, and also allowed us to focus on maintainable and testable code. In this talk, you will get an overview about problems we tackled as well as solutions we found and approaches to creating a more maintainable codebase.

What are we going to talk about?
First, let’s look at a few problems that we faced
Our problems…• Pretty big team (around 30 in development)
• Tightly bound code
• Enhancement work & New Projects going on at the same time; including rolling maintenance
• Support of legacy, kinda-legacy and new code
“How can we create a more maintainable codebase?”
“How can we automate common tasks?”
“How can we make debugging easier?”
“How can we create living documentation?”
Not every tool in the bag, but key parts of the foundation.
Importance of the full-stack being JavaScript…
• Back-end folks under a completely different team and in a different space
• Needed tooling that could be managed by our front-end teams
Grunt.js
Separate your custom tasks & configurations
Organization matters

Solutions!
Creating a more maintainable
codebase
Solution #1
Maintainability
• jQuery UI Widget Factory
• Linting, Testing and Style Guide
• Handlebars templates, Sass & Compass
Component based architecture
Reusability
• HTML Conventions
• Configurable components
• Reusable layouts
Separating concerns
Tooling focused on creating an
efficient workflow
Solution #2
Two Unique Workflows
1. Testing cycle, hot fixes, etc.
2. New and Enhancement efforts
Both workflows use common components but the approach is distinctly different.
Testing cycle, hotfixes, etc.grunt preview
• Reverse proxy against 25+ environments
• Live data sources
• Ability to localize any asset or data response
• Selective compilation
• Source maps to aid in debugging
• Rapid development of components & layouts
• Live previews that can be developed quickly
• Living Style Guide
• Yo for scaffolding
New and Enhancement effortsgrunt local
An intelligent and simple
build system
Solution #3

Intelligent build system
• Selective build for faster build times
• Several steps managed by one main task
• JSHint, QUnit, Uglify, Sass, and image optimization
• Dependencies
• Sass
• JS with Uglify
Automate as much as possible
Node and Grunt have allowed us to rapidly increase efficiency in
every phase of development
Thanks! !
