I have develop a signature using Html and java script where user can perform a signature,.
help will be appreciated :)
Thanks.
It all depends on what sort of DB you want to use to store the signature.
If you're using Rails and Amazon's S3 service you can use Active_Storage to assign the signature to a user.

I'm using https://github.com/szimek/signature_pad on the front end for capturing the user's input.
