Hi all- CEO of StackBlitz/author of this blog post here. Happy to answer any questions! (Also, thanks for posting this bpierre!)
I dont see any way to set breakpoints. When i use a debugger statement and open inspector it breaks on transpiled/packaged code (its different to the actual file). This is a deal breaker for me at present. Am I doing something wrong?

But you can do that same API emulation in regular browser JavaScript, too. What's the WASM intermediate buying here?
I think it is more complicated to emulate those api in normal browser environment compared to emulating some OS api for running node.js.
I used to teach web development and was always frustrated with just how much effort went into setting up a machine. It would be really nice if a developer could just include a script tag in their project that setup a TypeScript compiler inside service worker. I managed to get the basics down, even fixing relative import statements. Requests like localhost:3000/main.tsx would compile and cache on the fly. There were a…
Yes web developing is so hard... sudo apt install apache2 php libapache2-mod-php; vim /var/www/html/index.php
Most things can be simplified to the raw essentials, doesn't mean you're going to achieve a result that people want or need.

Why? It's literally JavaScript on both sides - what's complicated here?
If that works that means many intranet applications can be server-less. Both the JavaScript app and the "middle-tier" runs in the browser, and the middle-tier talks to MySQL server which is also on the intranet. All you need is a file server to serve the static JS files.

> the direction I'd like to see web development move is having a statically typed language that compiles to VM bytecode. Java… you want Java. And so the cycle continues!
That's a really good point. What we wanted all along was the JVM with a DOM API. We started with Java. It didn't gain any traction for browser scripting. They took "Java" out and called it JavaScript. Now we take the "script" out and call it WebAssembly. If someone in 1995 made Java a DOM-editing thing instead of an applet thing, we could have saved 25 years of running around in circles :) (Going back even further, w…
Overall it's hard to say how Sun could have won here, perhaps acquiring macromedia and using Flash technology to make a browser that ran those cool portals out of the box, and hey scripted first-class in Java too btw ;-)
To demonstrate the potential this needs a demo of a "middle-tier" service implemented in NodeJS. The service needs to talk to a MySQL database, and expose a Rest API to the web application. If that works that means many intranet applications can be server-less. Both the JavaScript app and the "middle-tier" runs in the browser, and the middle-tier talks to MySQL server which is also on the intranet. All you need is a…
Wouldn't it make more sense for the app to send SQL prepared statements to the database (via a tiny standardised wrapper on the server to enforce per-user permissions based on the authenticated session)?
It probably depends on whether other apps are requesting data from the same database, in which case it might make sense to convert from the relational model to JSON objects in a tier which exposes the objects over REST.

> WASM can't even talk to the DOM API directly For now. It's planned.
