About digital signature availability in Angular5

Is there a version of the component that is compatible with Angular 5?

Hi, @Lilit

Thank you for your interest with GroupDocs Signature.

The main Signature product implements as standalone server side (back-end) library.
For the Front-End solutions you may use any API oriented services you prefer

The only thing this requires exact behavior when working with the API, like

  • upload document on storage
  • request some operation (adding Digital Signature, verify or search)
  • receive signed document

Please share if it helps you or you are looking for other solutions?

Thank you!

Hi @yuriy.mazurchuk

Thank you, for your response!

And what about your viewer product? Is there front-end library for this one?

Hi @Lilit
you see, each these product (Signature/Viewer) supports working with the many document formats. so from the front-end perspective it would be extremely big weight client-side library. All GroupDocs products at this moment are the back-end library and for front-end there’s ability to use cloud API or implement own client-side gateway to call back-end
more similar examples here

so like you may try using on back-end Signature/Viewer and organize calls from your front-end to custom back-end API ( like having on the server Signature library to handle your requests)
I hope I did not mess the things up to you))
Please feel free to ask if there’s some unclear points.
Thank you!
