Create an Avatar Component in Gatsby with TypeScript Part 1

In this series we're going to take a look at creating a simple avatar component that is typed with TypeScript and has some special goodies in Gatsby land.

Let's start by identifying what our needs are for our avatar component.

  • Should show an image
  • Should be round
  • Should accept an image url
  • Should display an image based on a name (for small sets)

Cool, now we can start building our avatar. Start with an img element using a placeholder image as src. Add a little bit of styling to make it round and give it a size.

function Avatar(props) {
const { url, altText, title } = props;
const styles = {
width: '75px',
height: '75px',
borderRadius: '50%',
};
return <img style={styles} src={url} alt={altText} title={title} />;
}
export default Avatar;

Then we can pass it the image url and alt text. We can see that the component is working in its basic implementation now.

<Avatar url="https://res.cloudinary.com/joelmturner/monster-01.png" alText="Monster P. Whittington portrait" title="Monster P. Whittington" />
  • Should show an image
  • Should be round
  • Should accept an image url
  • Should display an image based on a name (for small sets)

Looks good. We've met our first three criteria for this component. In step 2 we'll make it more powerful with Gatsby Image.
