Is it possible to attach image in vcard of your code?, If any, where should I add that image?

Thanks for the code! Is it possible to create custom labels, for instance for the Work phone currently it just generates "phone:", how would i make it generate "office:" or "mobile:"?

@Ayyub-Kolsawala

Thanks for this. 👍

This works well. The helper methods are cleverly created in the Card object.

Yes. I could achieve this by using version 3.0 instead of 4.0. I could then construct it like so

tel: [
        { value: '555-555-555', type: 'Group office' },
        { value: '111-111-2222', type: 'General Office' },
        { value: '111-223-2222', type: 'Another department' }
    ],

Check this "https://www.geeksforgeeks.org/how-to-convert-image-into-base64-string-using-javascript/" to convert the image to base64 string then add it to vcf card with PHOTO;TYPE=PNG;ENCODING=b:
example
BEGIN:VCARD
VERSION:4.0
N:SMITH;John;;
FN:John Smith
NICKNAME:js
TITLE:Missing man too
TEL;TYPE=CELL:555-555-555
EMAIL;TYPE=WORK:john.smith@work.com
EMAIL;TYPE=HOME:john.smith@home.com
PHOTO;TYPE=PNG;ENCODING=b:base64 string
END:VCARD
