Hi communicty,

is there a better solution as this barcode scanner extension from wisej?

https://docs.wisej.com/extensions/extensions/barcode

the problem with the extension is, that the image is transfering first to server, then zxing decodes it and then transfer back the barcode.

this makes the scan process very slow. it would be better if the barcode scan recogination is done in browser it self.

something like this:

https://github.com/serratus/quaggaJS

or this:

https://zxing-js.github.io/library/

how would I implement js-based barcode scanner in wisej?

thanks for helping me.

Call the javascript. Use Eval or EvalAsync. It’s very simple. Load the js files, the call the js functions. Just like you would do in any html/js app following the github sample.

It’s better if you first create a blank web application without wisej to learn how to use the js extensions you linked. Once you have it working then use the same code with the wisej server side code calling it using Eval/EvalAsync as you did in the plain javascript application - just like the github sample.

ok great, thank you very much for fast answer! I will try it. But there is no own solution from wisej which works this way, right?

The only already created wisej solution is the barcode one that you already linked.
