Install and integration

1. Install: npm i @juandinella/penny-ds --save
2. Import styles in your index.js: import '@juandinella/penny-ds/index.css'
3. Add provider before router:

Methodologies

Atomic Design

For this project will be using the methodology to create componentes called Atomic Design. The component library will be creating just Atoms and Molecules with the following definitions:

Atoms definition

For this project an atom will be a component that is composed by an unique Atom with or without HTML tags, or just HTML tags.

Molecules definition

For this project a molecule is a component that is composed by at least 2 different atoms or stateful componentes

Organism definition

For this project organisms are assemblies of molecules functioning together as a unit

Components Library Creation Guide

Design Tokens

Design tokens are central and tiny pieces of UI information to store design related information such as colors, fonts, spaces, animations, etc... Their benefits is that they can be transformed and formatted to meet the needs of any platform (Android, iOS, Web, etc…).

We developed a tool that generates design tokens from Figma as a variables. The way it works is having a file config.figma.json with a Figma API Key and Figma ID and running npm run tokens. This will generate JSON files in tokens/json and this works as a single source of truth

Styling

Once Design Tokens are generated we have to create a file in src/styles/theme and import the tokens. This isn't automatically.

We use Styled Components

Creating a component

We have a CLI tool to create automatically a component. Run npm run cc (cc stands for create component)
