Simplify APDU's commands?

[jarodium]

Hello there

Is there any way we can simplify APDU sending and retrieving?
Working with the buffers seems to have quite a steep learning curve for folks who don't understand very much of the subject.

Hopefully a higher level API would be enough and more time saving for those who want this library to work.

The attached file below is an eID Belgian SDK doc, for example on how the APi could be structured

Below is an APDU.js file taken from the Open Smart Card Development Platform ( http://www.openscdp.org/index.html)

Hi!

Thanks for the comments. Answers inline

What's the difficulty when using Buffer? Can you more specific?. You can always initialize the Buffer with an Array, which looks quite simple to me.

If you could outline an specific API we could discuss it. By skimming through the document I'm not sure what you're exactly proposing.
On the other hand, I would argue that having a Sync API would help: #20. At the moment, I'm not in the need of a Sync API, but would certainly entertain a PR with that functionality.

Hello @santigimeno

Thank you for your reply.

Using buffer, may look simple, but from a first timer's pov, when using this lib and using APDU, I had a hard time figuring where the parameters for APDU should be entered, and I am still battling to figure out how to use all the cases in the spec.

About the API, I figure a Sync API would help, but I really don't mind like it is up untill now.
I can describe a small API specifically for general use.

Do you mind if I put the proposal in another issue?

Best regards

Please do! Looking forward to reading it.
