upload.

A tiny clientside uploader for s3 presigned URLs.

Built with SvelteKit+Svelte 5 and compiled into a single zip.

Setup

You'll need a bucket for the uploaded files, with CORS enabled.

$ aws s3api put-bucket-cors --bucket uploads --cors-configuration '{
    "CORSRules": [{
      "AllowedHeaders": ["*"],
      "AllowedMethods": ["PUT"],
      "AllowedOrigins": ["*"]
    }]
  }'

If you want to deploy your own copy of the site, deploy it to your static host of choice (S3?), substituting PREFIX = "https://YOUR_S3_BUCKET/" at the top of every .html file with your S3 bucket's domain.

$ cd $(mktemp -d)
$ curl -LO https://nightly.link/tombl/upload./workflows/build/main/site.zip
$ unzip site.zip
$ rm site.zip
$ find . -name "*.html" -exec sed -i 's/YOUR_S3_BUCKET/your-bucket/g' {} +
$ deploy .

To obtain an S3 presigned PUT URL, you can head to https://your-deployment/sign.

Usage

Navigate to https://your-deployment/#https://your-bucket/example.txt?X-Amz-..., substituting your presigned URL after the #.

The URL will be compressed via a custom compression scheme to ~2x shorter.

Copy the new shortened URL from the address bar and send it to your recipient, who can upload one or more files. If they upload multiple files, they'll be automatically zipped together.

Potential improvements

This is a tiny tool right now, built to meet very slim requirements. Here's a handful of polish/feature ideas:

• A second page to sign URLs in the browser
• An upload speed graph
• Multipart uploads
  • Faster and resumable
  • Likely requires a backend
• Text animations inspired by SwiftUI's .contentTransition(.numericText(value:))
• Picked file preview (thumbnails etc)
