My Journey

Where I’ve Come From

The Transition From Analogue To Digital

Where I Am Now

It’s still very much a journey

Learning new things on a daily basis

Responsive Web Design

Responsive Web Design Has Created Significant Challenges

A Need For A More ‘Agile’ Approach In Our Design Process

Design & Development Tools Have Changed

Dramatically

Countless Frameworks, Platforms, Content Management Systems, Site Generators etc.

Source code and version control management

Consistent Development Environments

Multi-device testing

Dependency And Package Managers, Preprocessors, Build Tools, And Methodologies

Coding Languages, Coding Style And Methodologies

CSS PreprocessorsLess

Sass (SCSS) Stylus

Huge Increase In EfficiencyMore Like A ‘Proper’ Programming Language

Functions Extends

And so on…

BEMBlock Element Modifier

.block {}

.block__element {}

.block__element--modifier {}

BEM helps us write CSS that…

Easy to scaleIs clear and obvious in its purpose

Is self-documenting

Designer & Front End Architect

–Elyse Holladay

“I want to build systems, architectures. I want my users to be my fellow developer and

designers as much as the end user. I want to make a site where the code on the inside

looks as great as the outside, and make it easy to do things like theme, A/B test, and build

new modules.”

Let’s Do This

Project Structure

Dependency Management

Build System Dependencies

grunt grunt-autoprefixer grunt-concurrent grunt-contrib-clean grunt-contrib-concat grunt-contrib-copy grunt-contrib-cssmin grunt-contrib-imagemin grunt-contrib-jshint grunt-contrib-uglify grunt-contrib-watch grunt-csscss grunt-modernizr grunt-sass grunt-scss-lint grunt-spritesmith grunt-stylestats load-grunt-config jshint-stylish time-grunt

Build System

Task Manager

Gruntfile.js

load-grunt-config - separate out task configsbuild environments - ‘prod’ and ‘dev’

module.exports = function(grunt) {

# Use load-grunt-config require('load-grunt-config')(grunt, {

jitGrunt: true, # Use fast plugin loader init: true, data: {

# $ grunt --env=prod (or) --env=dev env: grunt.option('env') || 'prod',

# src and dynamic dist locations project: { src: 'src', dist: '<% if (env === "prod") { %>tmp<% } else { %>dist<% } %>' } } }); };

Grunt Task Configs In Separate Files

aliases.js

module.exports = function(grunt, data) { var env = data.env || 'prod'; return { default: { # Default build tasks: [env] }, dev: { # Dev build tasks tasks: [ ‘concurrent:devFirst', 'concurrent:devSecond' ] }, prod: { # Production build tasks tasks: [ 'concurrent:prodFirst', 'concurrent:prodSecond' ] } }; };

concurrent.js

module.exports = { options: { limit: 3 }, devFirst: [ # 1st dev target 'clean:dev' ], devSecond: [ # 2nd dev target 'sass:dev', 'uglify:dev' ], prodFirst: [ # 1st production target 'clean:prod' ], prodSecond: [ # 2nd production target 'sass:prod', 'uglify:prod' ] };

Sass Tasks

grunt-sass - Uses fast libsass compiler grunt-scss-lint - Lint your SCSS files

css-min - Efficient CSS minifier

CSS Reporting Tasks

grunt-csscss - Find duplicated declarations grunt-stylestats - Evaluate & report CSS stats

And the rest…

grunt-autoprefixergrunt-modernizr

grunt-contrib-concat grunt-contrib-imagemin

grunt-spritesmithgrunt-contrib-jshintgrunt-contrib-uglifygrunt-contrib-watch

etc…

Gruntbase

https://github.com/gpmd/gruntbase

Git Hooks

post-merge

Runs after a `git merge` or `git pull`

1. Checks for changed files 2. Runs npm install && npm prune 3. Runs bower install && bower prune 4. Runs grunt

pre-commit

Runs before a `git commit`

1. Runs grunt 2. Won’t commit if build fails

git commit -m “My Message” -n

Initial Setup

setup.sh >

1. githooks.sh # Creates Git hook symlinks

2. build.sh # Installs dependencies and runs build
