Progress
The Progress component is an element that displays the progress status for a task that takes a long time or consists of several steps.
Installation
yarn add @bianic-ui/progress
# or
npm i @bianic-ui/progress
Import Components
import {
Progress,
ProgressLabel
CircularProgress,
CircularProgressLabel,
} from "@bianic-ui/progress"
Usage
<Progress value={50} />
Linear Progress
<Progress value={50} />
Color
Pass the color
prop to apply any color that exists in the theme to the
progress
<Progress color="pink" value={20} />
Sizes
Pass the size
prop to increase the height of the progress
<Progress size="sm" value={20} />
<Progress size="lg" value={20} />
Indeterminate
Pass the value
for the progress as undefined
to put the progress component
in the indeterminate state
<Progress margin="20px" size="xs" value={undefined} />
With stripe
Pass the hasStripe
prop to have a beautiful gradient to create a striped
effect on the progress
<Progress color="green" hasStripe value={20} />
With animation
Pass the isAnimated
prop combined with the hasStrip
prop to get a
beautifully animated progress
<Progress hasStripe isAnimated value={20} />
With label
Use the ProgressLabel
utility component to have a label for the progress
component
<Progress value={60}>
<ProgressLabel>60%</ProgressLabel>
</Progress>
Circular progress
<CircularProgress value={50} />
Circular progress size
Pass the size
prop to change the size of the circular progress. You can also
pass the thickness
prop to change the thickness of the circular progress. The
thickness
prop is a fractional value whose actual value is determined by the
size
of the circular progress. In this example the circular progress will have
a thickness of 30px. 50% of size (120px) => 30px
<CircularProgress size="120px" thickness={0.5} value={60} />
Circular progress color
Pass the color
prop to apply any color that exists in the theme
<CircularProgress color="pink" value={20} />
Circular progress with label
Use the CircularProgressLabel
utility component to have a label for the
circular progress
<CircularProgress value={60}>
<CircularProgressLabel>60%</CircularProgressLabel>
</CircularProgress>
Accessibility
- Progress has a role set to progressbar to denote that it's a progress bar
- Progress has aria-valuenow set to the percentage completion value passed to the component, to ensure the progress percent is visible to screen readers.
Note
The CircularProgress and the Spinner may seem to serve the same purpose, but
semantically, they don't. In the indeterminate
state the have the following
difference.
CircularProgress
It's used to denote the progress of a determinate operation. Take for example an image upload operation:
- Before upload begins, the upload progress is indeterminate (at this point, it’s just spinning),
- Once we know the size of the image and begin upload (using axios) then we update the progress value of the CircularProgress (at this point, it shows the progress). CircularProgress also comes with the aria-* attributes to make its progress value accessible to screenreaders.

Spinner
It's more of a “presentational” loading indicator you can use on a page or a component, while it’s loading or before it renders. It doesn’t have any semantic meaning.
To give meaning to a Spinner/loading indicator, ARIA standards require that you
mark the area of the component/page that’s loading with aria-busy=true
.
