Vercel Blob Integration FAQs

Question 1

Can I use this with non-Vercel hosting?

Accepted Answer

Yes, it provides the required callbackUrl configurations and v2.0.0+ patterns needed for onUploadCompleted to function correctly when the app is hosted outside of the Vercel environment.

Question 2

Does this skill prevent security leaks?

Accepted Answer

Question 3

How does this skill help with the 4.5MB Vercel limit?

It identifies when server-side uploads will fail due to Vercel's serverless function constraints and provides the necessary client-side handleUpload patterns to bypass those limits.

Question 4

Can I use this for files larger than 500MB?

Accepted Answer

Yes, the skill includes specific implementation patterns and rules for multipart uploads to handle very large assets efficiently while adhering to minimum chunk size requirements.

Question 5

Is Firefox supported for file streams?

Accepted Answer

Yes, it includes a specific fix for the Firefox ReadableStream fetch bug by providing patterns to convert streams to Blobs or ArrayBuffers for cross-browser support.
