How I work with unfamiliar libraries

When working with libraries I haven’t worked with before, examples help me the most. Using Sourcegraph, I can search millions of public repositories for where they are importing or using the same library as me. Usually, you’ll find someone doing what you want to do!

For example, I tried to use Astro’s <Picture /> component for my blog but didn’t know how to use the sizes attribute. Using Sourcegraph, I found a test doing exactly what I needed.

<Picture
  src={heroImage}
  width={720}
  height={360}
  alt=""
  sizes="100vw"
  widths={[720]}
  aspectRatio={720 / 360}
  formats={["avif", "webp"]}
  loading={"eager"}
/>
