React Native SVG loading indicator for remote SVGs


I am rendering SVGs from remote URLs:

import { SvgUri } from "react-native-svg";

function RemoteSVG() {
  return (
    <SvgUri
      uri={"https://cdn.orsive.com/avatars/3tYL96SMyBcwUakNphevH-avatar.svg"}
      style={{
        width: 100,
        height: 100,
        backgroundColor: "blue",
      }}
    />
  );
}

I want to show loading indicator/skeleton when the SVG is being fetched and loaded, but SvgUri component from react-native-svg doesn't have onLoad and onLoadEnd props. So, I tried setting backgroundColor, but once the SVG gets loaded, the background of the SVG also gets affected. It kinda looks like this:

avatar

Is there a way to show a loading skeleton when the SVG is being loaded?


Solution

  • Turns out I was using an old version of react-native-svg. I have switched to version 12.4.3 which has the onLoad prop. Here's what I did:

    import { useState } from "react";
    import { View } from "react-native";
    import { SvgUri } from "react-native-svg";
    
    function RemoteSVG() {
      const [loading, setLoading] = useState(true);
      return (
        <>
          <SvgUri
            uri={"https://cdn.orsive.com/avatars/3tYL96SMyBcwUakNphevH-avatar.svg"}
            onLoad={() => setLoading(false)}
            style={{
              width: !loading ? 100 : 0,
              height: !loading ? 100 : 0,
            }}
          />
          {loading && (
            <View
              style={{
                width: 100,
                height: 100,
                backgroundColor: "blue",
              }}
            />
          )}
        </>
      );
    }
