Shameless plug for my web-based Zint frontend: https://barcode.new (in-browser WASM)
I wrote it specifically because most online barcode generators don’t support vector output or suck in some other way: ads, signup necessary, code payload exposed to server-side processing etc.
Aside from obfuscating the source code to sell licenses, how does this benefit from WASM?
Barcodes have been generated for decades on low-resource embedded devices. Even what would have been a modest-to-low-end machine 25 years ago would have no problem handling the compute needed for this job.
On this end, it just looks like the user has to deal with the penalty of dealing with 1 MB of resources when hitting the main page.
The benefit of WASM in this case is that you can wrap a mature library written in C/C++ (in this case, Zint), and run it in a runtime that supports WASM, e.g. the browser. There's plenty of people who occasionally need to create barcodes, and not in some industrial, automated way, and a browser is just an easy way to accomplish that. Yes, you have 1MB loaded when you load the page, but hopefully that will be served from a cache.
One MEGAbyte?? How could you!?
