INTRO TO WEBCOMPONENTS
ABOUT ME ▸ Miguel Laginha ▸ Apereo Foundation ▸ Open
Academic Environment (OAE) ▸ ESUP-Portail
2018 WAS A LEAP YEAR FOR THE WEB.
YET NO ONE NOTICED. WHY?
WE'VE BEEN TOO BUSY DISCUSSING WHICH FRAMEWORK IS BEST
WHAT HAPPENED? FIREFOX 63
None
WE CAN ALL BE BFFS AND LEVERAGE EACH OTHER'S WITHOUT
ADOPTING EVERY ASPECT OT EACH OTHER'S WORK
ENTER WEB COMPONENTS =)
WHAT IS THAT?
1ST ANSWER IT'S NOT ANOTHER FRAMEWORK
2ND ANSWER IT'S A SET OF W3C STANDARDS
3RD ANSWER YES, IT'S AVAILABLE TODAY, EVERYWHERE
None
4TH ANSWER IT'S NOT EVEN A NEW IDEA! THERE'S PROOF
5TH ANSWER (FAV) THE WEB AS THE PLATFORM
<your-tag></your-tag> <!-- - Custom, reusable, encapsulated HTML tags - For
use in web pages and web apps - Work in all major browsers - JS agnostic -->
HTML TEMPLATE <template> CUSTOM ELEMENTS <your-tag/> ES MODULES <script type="module">
SHADOW DOM <slot>
ALRIGHT, BUT HOW?
LIBRARY DIFFERENCES EXAMPLE
HELLO WORLD EXAMPLE // taken from https://lit-element.polymer-project.org/ import { LitElement,
html } from 'lit-element'; class SimpleGreeting extends LitElement { static get properties() { return { name: { type: String } }; } constructor() { super(); this.name = 'World'; } render() { return html`<p>Hello, ${this.name}!</p>`; } } customElements.define('simple-greeting', SimpleGreeting);
WHAT'S IN IT FOR DEVS? ▸ CSS is scoped ▸
Custom HTML is semantic ▸ JS scoping is simpler ▸ Re-usable code ▸ Accessibility becomes manageable ▸ WC keeps design intentional
WHAT'S IN IT FOR MANAGERS? ▸ Lower maintenance costs ▸
Cost of development collapses ▸ Lower boilerplate and churn for future projects ▸ Extensibility ▸ It's a W3C standard, no legacy
I'M SOLD, LET'S TRY IT
A GLIMPSE INTO THE FUTURE!
A GLIMPSE INTO THE FUTURE ▸ video players ▸ dropdown
menus ▸ timelines ▸ animations ▸ all sorts of visual and non visual components
ADVANTAGES IN A NUTSHELL ▸ 100% re-usable components (style, business
logic or mixed) ▸ Split work among teams ▸ CDN served components ▸ No need for greenfield projects, upgrade step by step! ▸ No need for a framework ▸ Avoid (platform) lock-in
BARRIERS TO ADOPTION ▸ Lots of libraries already (litElement, skateJs,
Stencil, slimJS, etc) ▸ Requires proper JS knowledge ▸ Requires tooling (webpack, lerna, rollup, npm, git, etc...) ▸ Deployment ▸ Documentation
WHO'S USING? ▸ Youtube: https://www.youtube.com/ ▸ EA: https://www.ea.com/en-gb ▸ https://www.webcomponents.org/
▸ https://www.byu.edu/
COMMUNITY RESOURCES ▸ OpenWC ▸ WebComponents.org ▸ Try litElement ▸
Polymer ▸ Compatibility ▸ dev.to
THANK YOU. Q&A TIME
