Render File Upload App

This app lets you upload a file or a folder and get a direct download link.

Example deployed link:

https://your-app.onrender.com/files/abc123

What it does

• Opens a small upload page at /
• Accepts single-file uploads
• Accepts folder uploads from browsers that support folder picking
• Saves uploaded content in uploads/
• Returns a direct download link
• Packs folders into a single .zip file before upload for faster transfer

Run locally

npm install
npm start

Then open:

http://localhost:3000

Change the download path

By default, links use:

/files/:id

To change that on Render, set:

BASE_PATH=myname

Then your links would look like:

https://your-app.onrender.com/myname/abc123

Important

This is a simple starter.

• Uploaded files are stored on the Render instance filesystem
• On many Render setups, uploaded files are not permanent across redeploys or restarts
• Folder uploads are converted in the browser into a single .zip archive, then uploaded as one file

If you want permanent file hosting, the next step is to store uploads in a real object store like S3, Cloudinary, or Uploadcare.
