I'm afraid the DataMatrix reader was disabled on the demos.

Was this the expected result?

Yupp, and im able to scan my card in the stackblitz demo aswell. issue may be marked as solved.

Is there anything special i need to do to activate it in my own code?

[odahcam]

By default only the QR code decoder comes enabled, there's some options to enable the others, I think the most simple is this one:

<zxing-scanner [formats]="['QR_CODE', 'EAN_13', 'CODE_128', 'DATA_MATRIX']"></zxing-scanner>

As you can see, you can use the formats property to achieve that.

Great!

Could you add that to: https://github.com/zxing-js/ngx-scanner/wiki/Getting-Started and/or https://github.com/zxing-js/ngx-scanner/wiki/Advanced-Usage ??

[odahcam]

Of course: https://github.com/zxing-js/ngx-scanner/wiki/Getting-Started#choosing-what-decoders-to-run

I should've already added that before anyway.

[mattiaskagstrom]

Thats why I thought it didn't work when I added <zxing-scanner></zxing-scanner> to my app ;)

is there a list of all avalible formats?

[odahcam]

Yeah! This feature relies directly on the ZXing's core, so you can find'em here: https://github.com/zxing-js/library/blob/master/src/core/BarcodeFormat.ts
