EmailTldValidator

A simple email address validator for Elixir that first checks the address with a regular expression and then checks if the Top-Level Domain of the host is included in ICANN's List of Top-Level Domains. The package is meant for use with Ecto.Changeset.

Installation

If available in Hex, the package can be installed by adding email_tld_validator to your list of dependencies in mix.exs:

def deps do
  [
    {:email_tld_validator, "~> 0.1.0"}
  ]
end

Usage

The features of this library are split into two modules: EmailTldValidator and EmailTldValidator.Ecto.

To just check if an e-mail is valid outside of an Ecto.Changeset, use EmailTldValidator/1:

EmailTldValidator.email_valid?("user@example.com")
# => true

EmailTldValidator.email_valid?("user@example")
# => false (does not match the regular expression)

EmailTldValidator.email_valid?("user@example.foobar")
# => false (non-existent TLD)
