Developers struggle with synchronous file I/O in Node.js that blocks event loops under heavy load and browsers filling users' disks with unbounded localStorage data. SyncShield provides an automated runtime layer that rewrites sync calls to non-blocking async patterns and enforces per-domain storage quotas, keeping servers responsive and users' devices from filling up.

Comment on: HTML5 localStorage allows sites to fill up users' hard disks
So synchronous APIs wouldn't be a problem if they were 1. Asynchronous or 2. Guaranteed to be really really fast? You do realize that the problem is that you can't guarantee that spinning rust will be fast, right?
Try to do that on a production server that has to handle 1000 requests readFileSyncing at the same time ...sync apis are just a conveniance for console applications, they are not meant for a web server.So yes node.js DOES impose async programming for everything or node doesnt scale.
