Component Library Workshop

https://courses.joshwcomeau.com/css-for-js/03-components/17-workshop

(Note to self: Testing Voiceover on Mac? Run storybook http://localhost:6006 on Chrome, not on Firefox.)

In this workshop, we'll build 3 components from scratch:

ProgressBar
Select
IconInput

Most of the pertinent information will be stored in the Figma document (https://www.figma.com/file/u0wCdLXheiN9f2FmAuPsE9/Mini-Component-Library), but this README will contain some additional information to help you on your mission!

Two fully-formed components have already been included, to be used as-needed in your work:

Icon, an icon component that uses react-feather to render various icons
VisuallyHidden, a component that allows us to make text available to screen-reader users, but not to sighted users.

Additionally, all of the colors you'll need are indexed in constants.js.

All components in this project use the Roboto font. This font is already included in the Storybook environment, and is already applied to all elements. It comes in two weights:

400 (default)
700 (bold)

Running Storybook

This project uses Storybook, a component development tool.

First, install dependencies with npm install.

Once dependencies are installed, you can start storybook by running:

npm run start

Once running, you can visit storybook at http://localhost:6006.

The Components

ProgressBar

The figma document mentions that this component should be "accessible". You can learn how to build a semantically-valid, accessible progress-bar component by reading this doc: https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_progressbar_role

This component uses a box shadow. We haven't seen this property yet! For now, you can achieve this effect by copying the following CSS declaration into your component:

box-shadow: inset 0px 2px 4px ${COLORS.transparentGray35};

We'll learn much more about the box-shadow property in future modules =)

Select

The Select component will need a down-arrow icon! You can use the chevron-down ID with the Icon component.

We want to use a native <select> tag in this component, so a bit of precursory HTML has been provided.

This component also includes a function, getDisplayedValue. This component uses some React APIs to work out the text that should be displayed. The value isn't currently used, but you can make use of it if needed, depending on your implementation.

IconInput

This component also uses the Icon component — the specific ID will be provided as a prop.

This component requires bold text. You can achieve this look by using font-weight: 700.
