Tooling for Modern Web App Developer

Front-end development workflow is becoming increasingly demanding as the complexity of the environment grows. Thankfully, there are many tools that can make your life as a front-end developer easier and perhaps, more rewarding.

The primary objective of this session is to get an idea about end-to-end front-end workflow and useful tools. We will discuss hot tools like Yeoman, Grunt and Bower. But the session is not limited to these tools - we will touch each phase of front-end development like boiler-plating, preprocessors, performance, documentation, code quality, reporting and architecture etc.

16. Scaling backbone apps
17. Backbone never tell how to create reusable modules and load it on demand
18. Asynchronous Module Definition (AMD) Modular Javascript
19. Modular Javascript Purpose Module? Highly decoupled, distinct pieces of functionality stored in modules Dependency References
20. Modular Javascript Two Steps 1. Define module 2. Require it
21. Modular Javascript
22. Modular Javascript Configuration Require module Define module & its dependencies 1 2
23. Modular Javascript Combine related scripts together Minifies it via UglifyJS/ Closure Compiler Optimize CSS r.js optimizer $ node r.js -o baseUrl=. paths. jquery=some/other/jquery name=main out=main- built.js
24. Modular Javascript AMD loaders curljs ES6 Module
25. Test Driven Development TDD / BDD
26. TDD / BDD Why TDD? Design your code well Build confidence to use your code Don’t let same bug popup twice Seamless change requests adaption Automatic Documentation Continuous Integration
27. Fail Pass Refactor TDD / BDD PROCESS
28. TDD / BDD Qunit Fixture Source file Tests
29. TDD / BDD Qunit Group test Test cases
30. TDD / BDD Qunit

34. Performance tuning & Optimization
35. Javascript lint Code Quality Tools for detecting potential problem in your javascript
36. Chrome dev tool Timeline
37. Chrome dev tool Profiling
38. Chrome dev tool Tracing chrome://tracing/
39. JavaScript performance http://jsperf.com/ http://dromaeo.com/
40. Documentation YUI Natural Docs Docco
41. Documentation
42. Continuous Integration & Code coverage
43. Code coverage http://jsoverson.github.io/plato/examples/jquery/ Plato
44. Code coverage plato istanbul jscover blanket.js jscomplexity.org Tools
45. Continuous Integration Continuous integration – the practice of frequently integrating one's new or changed code with the existing code repository – should occur frequently enough that no intervening window remains between commit and build, and such that no errors can arise without developers noticing them and correcting them immediately CI -wikipedia
46. Travis-ci.org Tests Git push
47. Session Summary Structure your app Optimise it Document it Continuous integration
48. CSS
49. CSS Libraries Bootstrap Pure Foundation Topcoat inuit
50. CSS Preprocessors
51. What is CSS Preprocessors Stylesheet meta language that is interpreted into CSS $basecolor: #f1f1f1; body{ background: $basecolor } body { background: #f1f1f1; } SC SS C SS
52. CSS is Awesome! but Maintaining :) :(
53. S C S S
54. S C S S partials @import @extend @include @if @for %placeholder
55. Compiling Deployment Server Client Local Compile as part of deployment process (Capistrano, Fabric). Compile and cache up on request. Compile using javascript at browser end (not recommended) Compile using tools.
56. Tools Prepros
57. Online Tool
58. Preprocessors don't output bad code, bad developers do
59. Structure your CSS
60. Repetition Maintainability Decoupling Specificity
61. OOCSS BEM SMACSS Methodologies
62. OOCSS Purpose of OOCSS is to identify common pattern & encourage code reuse Main principles Separate structure and skin Separate container and content
63. BEM Block : A block is an independent entity. Element : An element is a part of a block that performs a certain function. Blocks and elements constitute page content. Modifier : Similar block with slightly altered its appearance or behavior..
64. SMACSS Base : Base rules are the defaults. Layout : Divide the page into sections. Layouts hold one or more modules together. Module : are the reusable, modular parts of our design. State : are ways to describe how our modules or layouts will look when in a particular state. Is it hidden or expanded? Theme : are similar to state rules in that they describe how modules or layouts might look.
65. Living Style guide Create style guide as you code!!
66. Github style guide https://github.com/styleguide/css
67. KSS style guide /* A button suitable for giving stars to someone. :hover - Subtle hover highlight. .stars-given - A highlight indicating you've already given a star. .stars-given:hover - Subtle hover highlight on top of stars-given styling. .disabled - Dims the button to indicate it cannot be used. Styleguide 2.1.3. */ a.button.star{ ... } a.button.star.stars-given{ ... } a.button.star.disabled{ ... }
