Aaron K SaundersThis is a post to support the video I did on the same topic. The video was split into two parts, one covering setting up Ionic Framework in ReactJS to work with the Capacitor Camera Plugin, and the other part was to upload the image captured from the camera to Supabase Storage.
The Video
Uploading the Camera Image
All of the magic happens here
/**
* upload to storage bucket, convert path to blob
* get file name from path
*
* @param path
*/
const uploadImage = async (path: string) => {
const response = await fetch(path);
const blob = await response.blob();
const filename = path.substr(path.lastIndexOf("/") + 1);
const { data, error } = await supabase.storage
.from("image-bucket")
.upload(`${filename}`, blob, {
cacheControl: "3600",
upsert: false,
});
if (error) alert(error?.message);
console.log(data);
getAllImages();
return true;
};
We take the webPath from the Capacitor Camera Plugin and use fetch to get a blob which we then upload to supabase.
Downloading the Image From Supabase
What I do here is create a seperate component RenderImage and in the initial useEffect hook, I make an API call to supabase to get the publicURL of the image and set it to a local state variable, when the variable is set, the image is drawn to the screen.
const RenderImage: React.FC<any> = ({ path }) => {
const [publicUrl, setPublicUrl] = useState<any>("");
useEffect(() => {
(async () => {
const { publicURL } = supabase.storage
.from("image-bucket")
.getPublicUrl(path);
setPublicUrl(publicURL);
})();
},[path]);
return <IonImg src={publicUrl} />;
};
All The Rest...
the rest of the video is a more detailed explanation of the supabase api and how you need to setup the buckets for use.
