Style Guides, Pattern Libraries, Design Systems and other amenities.

Style guides and component libraries are the new trend in front-end development.
Everyone is into "Atomic Design" and "Modular CSS" nowadays.
But how did we get to this “hype”, and why? What is a style guide, what is its value and where are the benefits of introducing one in a project? And are them useful only for the web, or can be employed by other platforms too?
I'll try to give an answer to all these questions in this presentation – directed to designers, web developers but also iOS/Android/Win developers – and I'll show how our Mobile Web team in Badoo has developed his first style guide and how is using it to catch bugs and create a shared pattern library.

  26. Nomenclature

  27. Pattern Library This is a library of standardised UI patterns.

    They are the final designs, and can be delivered in the form of a repository of design files, or a symbol library/UI kit. It is the resource for designers to build from. Style Guide This is the documentation resource for the design system. Since the design system is purely code and assets, the style guide is a site to demonstrate the UI patterns with references to aid in implementation and usage. Design System The entirety of the standardised UI patterns, frameworks, assets, and documentation, as well as the processes and people involved. It is the ecosystem that drives and supports the unified evolution of the product(s). Definitions Clarifying our “Style Guide” Nomenclature - Nate Baldwin

  82. Conclusions

  83. Takeaway #1 A design system impacts a whole company,

    only its tech/dev teams.
  84. Takeaway #2 Building a design system is a long process.

    So don’t build a style guide because is cool. 
 Do it if is useful & solves business problems. And while doing it, have clear in mind what are your objectives and top-level goals.
  85. Takeaway #3 A style guide improves the communication between all

    the members of an organisation. It has to create a more cohesive user experience, encourage collaboration, and create efficiencies. A design system is made by artefacts, people, and products. Don’t forget the people. Brad Frost - Clarity Conference writeup
