Please refer to the CodePen example (link above).
Overview of the code:
Upload once at the start of your app.uploadFile from your <input onchange="..."> handlers.onProgress to display the upload progress for each input element.onUploaded fires, record the fileUrl from the callback's argument to a local variable.onUploaded has fired for all files, the form is ready to be submitted.Note: file uploads will safely run in parallel, despite using the same Upload instance.
Given an uploaded image URL:
https://upcdn.io/W142hJk/raw/HhVSQ5ZQ5bfqvanQ
Resize with:
https://upcdn.io/W142hJk/thumbnail/HhVSQ5ZQ5bfqvanQ
Auto-crop (to square dimensions) with:
https://upcdn.io/W142hJk/thumbnail-square/HhVSQ5ZQ5bfqvanQ
Tip: for more transformations, please create an account.
To crop images using manually-provided geometry:
<html>
<head>
<script src="https://js.upload.io/upload-js/v2"></script>
<script>
const upload = Upload({
// Get production API keys from Upload.io
apiKey: "free"
});
// Step 1: Upload the original file.
const onOriginalImageUploaded = async (originalImage) => {
// Step 2: Configure crop geometry.
const crop = {
// Type Def: https://github.com/upload-io/upload-image-plugin/blob/main/src/types/ParamsFromFile.ts
inputPath: originalImage.filePath,
pipeline: {
steps: [
{
geometry: {
// Prompt your user for these dimensions...
offset: {
x: 20,
y: 40
},
size: {
// ...and these too...
width: 200,
height: 100,
type: "widthxheight!"
}
},
type: "crop"
}
]
}
}
// Step 3: Upload the crop geometry.
const blob = new Blob([JSON.stringify(crop)], {type: "application/json"});
const croppedImage = await upload.uploadFile(blob);
// Step 4: Done! Here's the cropped image:
return croppedImage;
};
const onFileSelected = async (event) => {
const [ file ] = event.target.files;
const originalImage = await upload.uploadFile(file);
const croppedImage = await onOriginalImageUploaded(originalImage)
alert(`Cropped image:\n${croppedImage.fileUrl.replace("/raw/", "/thumbnail/")}`)
}
</script>
</head>
<body>
<input type="file" onchange="onFileSelected(event)" />
