What is a design system?
A collection of reusable components, guided by clear standards, that
can be assembled together to build any number of applications.
None
A design system is a combination of style, components, and
voice.
It is scalable at any level
Provides consistency between different pages and applications
With the set of rules and guides, increases the efficiency
Enhances the teamwork and eases the on-boarding of new members

Components
Components support levels of abstraction in an application. It is
layered and feature-based.
Individual components provide decoupling which leads to better unit testings
and stability.
Design system and Components combine mostly in UI layer where
your presentation occurs
Besides, components can also communicate with the data layer while
rendering our content.
…and with the standardisation, it improves quality.

How Popular Libraries Think?
Build encapsulated components that manage their own state, then compose
them to make complex UIs.
Components define areas of responsibility in your UI that let
you reuse these sets of UI functionality.
It’s an abstraction that allows us to build large-scale applications
composed of small, self-contained, and often reusable components.
But the mainly, they should have a responsibility over a
single part.
None
How to Organise?
Define your folder structure based on their functionalities
Think of everything is sort-of a pluggable component. In most
cases, when you remove it, you should expect no traces left.
// DON’T . !"" controllers | !"" cart.js | #""
checkout.js !"" models | !"" cart.js | #"" checkout.js #"" views !"" cart.pug #"" checkout.pug // DO . !"" cart | !"" index.js | #"" template.pug #"" checkout !"" index.js #"" template.pug
…and tests are a part of your components.
// add test specs . !"" cart | !"" index.js
| !"" test.spec.js | #"" template.pug #"" checkout !"" index.js !"" test.spec.js #"" template.pug
Separate config and scripts away from your components.
. !"" config | !"" index.js | #"" server.js !""
scripts | !"" build.sh | #"" post-install.sh !"" test | !"" index.js | #"" setup.spec.js !"" cart | !"" index.js | !"" test.spec.js | #"" template.pug #"" checkout !"" index.js !"" test.spec.js #"" template.pug
Keep HTML and CSS separate in your source code and
never inline manually
// DON’T <p style="margin: 10px 0; padding: 0;">Hello World! </p>
// DO .content-text { margin: 10px 0; padding: 0; } <p class="content- text">Hello World!</p>
Always think about specificity in CSS, try to avoid creating
specific selectors
// DON’T #main .article .title span { font-size: 32px; font-weight:
bold; } // DO .main-article-title { font-size: 32px; font-weight: bold; }
Do not write the code you are going to overwrite
// DON’T .content { display: flex; max-width: 1280px; margin: 0
auto; } .article { width: 900px; } .supplementary { width: 380px; } @media screen and (min-width: 48.0625em) and (max-width: 64em) { .article { width: 644px; } } @media screen and (max-width: 48em) { .content { flex-direction: column; } .article, .supplementary { width: 100%; } } // DO .content { max-width: 1280px; margin: 0 auto; } @media screen and (min-width: 48.0625em) { .content { display: flex; } .article { flex: 1; } .supplementary { width: 380px; } }
A way to unify different frameworks?
Web components are a set of web platform APIs that
allow you to create new custom, reusable, encapsulated HTML tags to use in web pages and web apps.
Custom components and widgets build on the Web Component standards,
will work across modern browsers, and can be used with any JavaScript library or framework that works with HTML.
<script type="module" src=“components/nav/app- drawer“></script> <app-drawer raised class=“indigo">raised</app-drawer>
<script> class AppDrawer extends HTMLElement {...} window.customElements.define('app-drawer', AppDrawer); </script> <app-drawer></app-drawer>
Good part, all JS frameworks outputs to HTML. Theoretically, we
can use any popular JS library to create Web Components
What is more?
Having self-contained, reusable components helps to turn you app to
micro frontends
… that can have independent deployment, build, coding
… leads to autonomous teams
… and you can have a shell that orchestrates which
micro frontend to load
… with the “Best Friend of Frontend"
Your components should not know what the dependencies are in
behind the curtains you are using.
It should only aware of which functions are available for
a particular action.
Every dependency comes with a technical debt for the future.
Thank you @bcinarli
