In this post, I will introduce a simple spinner that uses reactjs + styled-components.
Spinner
https://vdxkbn.csb.app/
[props]
interface SpinnerProps {
width?: string;
height?: string;
borderWidth?: string;
borderColor?: string;
duration?: number;
}
Actually, the main part is CSS (styled-components).
Create an animation and passing it to a created style, SpinnerBody.
The structure is quite simple.
width, height, and boarderWidth can be number or string | number. I use string because I would like to pass the value with rem or px.
const spinnerAnimation = keyframes`
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
`;
const SpinnerBody = styled.div<SpinnerProps>`
height: ${(p) => (p.height ? p.height : "4rem")};
width: ${(p) => (p.width ? p.width : "4rem")};
border: ${(p) => (p.borderWidth ? p.borderWidth : "4px")} solid #d1d5db;
border-top-color: ${(p) => (p.borderColor ? p.borderColor : "#3b82f6")};
border-radius: 50%;
animation: ${spinnerAnimation}
${(p) => (p.duration ? `${p.duration}ms` : "800ms")} linear infinite;
`;
export const Spinner = (props: SpinnerProps) => {
return <SpinnerBody {...props} />;
};
