No validation of Country Code.

Whatsapp Dynamic Link (wa.me) requires a country code in the beginning. Currently, no such validation is preventing it from redirecting.

Is this up for grabs?

Sure go ahead @cryptus-neoxys

What would be the best approach for this?

• IP address lookup to get user's location (probably overkill)
• GeoLocation API? (poor UX, possibly)

[iamyajat]

If I'm not wrong, for geolocation, the user will have to grant location access which I think will harm the simplicity of the app.

Maybe this can be used to get the country.

$.get("http://ipinfo.io", function(response) {
    console.log(response.city, response.country);
}, "jsonp");

One more thing, if the user pastes the number directly with a country code then, modify the selected country automatically.

Yeah, similar issues regarding geolocation API requesting permission.

Here's what I could think of as a better alternative: Use geolocation-db's ultimate free service to get the Country data and map that to country Phone code Country Code to Phone Code-JSON
This can then be cached on the user's device for a seamless exp (PWA and whatnot xD)

Looks good!
