@brucel

@brucel Holy Web Wars • IE vs Netscape • Tables
vs CSS • jQuery vs vanilla JS • Angular vs Ember vs React

@brucel

@brucel • Something about being convinced by component-based architecture

@brucel

@brucel Because of • Re-usability • Composability • Testability •
Shareability

@brucel

@brucel Why is CSS for components a PITA? • Everything
is global • Order aﬀects cascade • Dependency system - @import • Relies on markup structure • Breaks silently

@brucel CSS-in-JS

@brucel document.tags.H1.fontSize = "20pt";

@brucel Warning: OPINION AHEAD

@brucel

@brucel Legal notice: Other opinions are available. (But wrong)

@brucel Good old CSS: • IDE support • syntax highlighting
• code completions • validations • CSS generators • huge community

@brucel Designers, designers, designers, designers

@brucel CSS-in-JS costs us! • Loading JS library to handle
CSS creation at runtime • Creating / modifying stylesheets at runtime • Server-Side Rendering = CSS × 2

@brucel

@brucel Ido’s dream • Modular • Dynamic • Performant •
CSS capabilities • Tooling • Customization

@brucel Introducing Stylable is a CSS preprocessor for styling components
with typed CSS.

@brucel Abstraction - custom states .gallery:loading::navBtn { visibility:hidden; }

@brucel Abstraction - inner parts .gallery::navBtn::icon { color:green; }

@brucel Typed CSS • CSS Superset • Inner parts as
Pseudo-Elements • Create custom Pseudo-Classes • Type aware dependencies • IDE & Build support • Optimization - "ruleset shaking"

@brucel .gallery:loading::navBtn {} page.st.css :import { -st-from: "./gallery.st.css"; -st-default: Gallery;
} .gallery { -st-extends: Gallery; background-color: gold; }

@brucel Styling inside the gallery :import { -st-from: "./gallery.st.css"; -st-default:
Gallery;} .gallery { -st-extends: Gallery; background-color: gold;} .gallery:loading::navBtn { visibility: hidden;}

@brucel Deﬁning Gallery internals .root { … } Gallery:loading gallery.st.css:

@brucel Deﬁning Gallery internals .root { -st-states: loading, empty; }
Gallery:loading gallery.st.css:

@brucel :import { -st-from: "./icon-button.st.css"; -st-default: IconButton;} .root { -st-states:
loading, empty;} .navBtn { -st-extends: IconButton;} Gallery::navBtn::icon gallery.st.css: Deﬁning Gallery inner navBtn

@brucel Status of Stylable • Pseudo Elements & Classes •
Imports • Mixins • Theming • VSCode Extension • Integration - React, Webpack

@brucel W.I.P. • Pseudo-Classes with parameters: .grid::column:name("email") {color:goldenrod;} • Formatters:
.item {color: darker(red);} • Declaration Interfaces • MOAR Integrations • Dogfooding and battle-testing • Web Components Compatibility, Houdini

@brucel World Bank: Landlocked countries generally pay higher prices for
bandwidth than coastal countries. In Africa, for instance, being landlocked adds an average of US$232 to the monthly price for fixed broadband access. World Bank. 2016.

@brucel for mobile broadband too, the range is more than
100-fold between Pakistan (US$1.48 for a GB of data a month, downloaded to a mobile handset) and São Tomé and Príncipe (US$169.38). “

@brucel Paradox The employment rate in connected areas relative to
unconnected areas increased by between 4.2% and 10% when fast internet became available. Fast internet and employment in Africa http://voxdev.org/topic/technology-innovation/fast-internet-and-employment-africa “

@brucel In most countries in our sample, the increase in
skilled employment was biggest for workers with secondary or tertiary education, but those who only completed primary school were also more likely to hold a job. “

@brucel Despite the fact that Africa has the lowest income
per capita of any region, affordability was only identified as the most important barrier in one out of 13 markets in our survey.   “ Africa: not just affordability - GSMA Consumer barriers to mobile internet adoption in Africa - July 2016

@brucel Network coverage was not perceived as an issue in
most countries, reflecting the increasing availability of mobile networks. However, mobile broadband (3G or 4G) coverage remains low in most parts of Africa.   “ Africa: not just networks - GSMA Consumer barriers to mobile internet adoption in Africa - July 2016

@brucel A lack of awareness and locally relevant content was
considered the most important barrier to internet adoption in North Africa and the second biggest barrier in Sub-Saharan Africa.   “ Lack of awareness/ content. - GSMA Consumer barriers to mobile internet adoption in Africa - July 2016

@brucel A lack of digital skills was identified as the
biggest barrier to internet adoption in Sub-Saharan Africa and the second biggest in North Africa.   “ Lack of digital skills - GSMA Consumer barriers to mobile internet adoption in Africa - July 2016

@brucel A lack of awareness and locally relevant content was
the most commonly cited barrier to internet adoption: 72% of non-internet users across the six survey markets felt this was a barrier.   “ Asia - GSMA Consumer barriers to mobile internet adoption in Asia - January 2016

@brucel 50% of websites worldwide are in English, a language
spoken by only 10% of speakers in the survey countries. By way of contrast, only 2% of websites worldwide are in Mandarin and less than 0.1% are in Hindi.   “ Asia - GSMA Consumer barriers to mobile internet adoption in Asia - January 2016

@brucel In Africa, 7 in 10 people who do not
use the internet say they just don’t know how to use it, and almost 4 in 10 say they do not know what the internet is.   In high-income Poland and the Slovak Republic, one- fifth of adults cannot use a computer. “ Digital illiteracy? - World Bank

@brucel 41% do not use the internet at all, 53%
do not have broadband access at home, and 23% do not use cell phones. “ American seniors - Older Adults and Technology Use (Pew Research Centre, April 2014)

@brucel Rural mobile internet users grew by a staggering 93%
between December 2014-Dec 2015, yet only nine per cent of the hinterland has access to the technology. In comparison, 53% of urban areas had mobile internet connectivity and grew at 71% during the same period. “ Digital Divide (India) - Times of India, 3 Feb 1016

@brucel Making the internet universally accessible and affordable should be
a global priority. “ World Bank

@brucel In Nigeria, the data needed to watch just 2
minutes of online video a day can cost more than sending a child to school for a month. “ Nigeria - How To Make Internet Affordable

@brucel

@brucel • Settle on fair and transparent ICT taxes. •
Get governments and donors to step up efforts. • Agree on “affordability”: 1 GB for 2% • Invest in public access solutions. • Make getting women online a top priority. Fast Africa

@brucel Online work can prove particularly beneficial for women, youth,
older workers, and the disabled, who may prefer the flexibility of working from home or working flexible hours. “ Online work

@brucel In India… women are 62% less likely to use
the internet than men. Many of the underlying reasons for this – affordability, skills and content – are the same as for men; they are simply felt more acutely by women. “ Gender divide - GSMA Consumer barriers to mobile internet adoption in Africa - July 2016

up the Kudumbashree project to outsource information technology services to cooperatives of women from poor families; 90 percent of the women had not previously worked outside the home. “ “Prosperity of the family”

Early progressive web apps in Asia & Africa @brucel

@brucel Downloading a typical app with 20 MB APK can
take more than 30 minutes on a 2G network, and the download is likely to fail before completion, due to the flaky nature of the network. “ - How we built Facebook Lite for every Android phone and network

@brucel Warning: Liberal handwringing ahead

@brucel Guard the web as you work on it Someone
or something or some combination of people and things is using YouTube to systematically frighten, traumatise, and abuse children, automatically and at scale, and it forces me to question my own beliefs about the internet, at every level. https://medium.com/@jamesbridle/something-is-wrong-on-the-internet-c39c471271d2

@brucel Access to the internet is critical, but not sufﬁcient
“ World Bank:

@brucel the full benefits of the information and communications transformation
will not be realized unless countries continue to improve their business climate, invest in people’s education and health, and promote good governance. “

offline population. “ - State of Connectivity 2014, internet.org

@brucel

@brucel an increase in Internet maturity similar to the one
experienced in mature countries over the past 5 years creates an increase in real GDP per capita of $500 on average during this period. “ Internet matters - The Net’s sweeping impact on growth, jobs, and prosperity (McKinsey Global Institute)
