Upgrade from 1.x to 3.x

Mailchecker public API has been normalized, here are the changes:

  • NodeJS/JavaScript: MailChecker(email) -> MailChecker.isValid(email)
  • PHP: MailChecker($email) -> MailChecker::isValid($email)
  • Python
import MailChecker
m = MailChecker.MailChecker()
if not m.is_valid('bla@example.com'):
  # ... 

became:

import MailChecker
if not MailChecker.is_valid('bla@example.com'):
  # ... 

MailChecker currently supports:


var MailChecker = require('mailchecker');
 
if(!MailChecker.isValid('myemail@yopmail.com')){
  console.error('O RLY !');
  process.exit(1);
}
 
if(!MailChecker.isValid('myemail.com')){
  console.error('O RLY !');
  process.exit(1);
}
<script type="text/javascript" src="MailChecker/platform/javascript/MailChecker.js"></script>
<script type="text/javascript">
if(!MailChecker.isValid('myemail@yopmail.com')){
  console.error('O RLY !');
}
 
if(!MailChecker.isValid('myemail.com')){
  console.error('O RLY !');
}
</script> 
include __DIR__."/MailChecker/platform/php/MailChecker.php";
 
if(!MailChecker::isValid('myemail@yopmail.com')){
  die('O RLY !');
}
 
if(!MailChecker::isValid('myemail.com')){
  die('O RLY !');
}
Code.require_file("mail_checker.ex", "mailchecker/platform/elixir/")
 
unless MailChecker.valid?("myemail@yopmail.com") do
  raise "O RLY !"
end
 
unless MailChecker.valid?("myemail.com") do
  raise "O RLY !"
end
# no package yet; just drop in MailChecker.py where you want to use it. 
import MailChecker
 
if not MailChecker.is_valid('bla@example.com'):
    print "O RLY !"

Ruby

require 'mail_checker'
 
unless MailChecker('myemail@yopmail.com')
  fail('O RLY!')
end
 
unless MailChecker.valid?('myemail@yopmail.com')
  fail('O RLY!')
end
; no package yet; just drop in mailchecker.clj where you want to use it.
(load-file "platform/clojure/mailchecker.clj") 
 
(if (not (mailchecker/valid"myemail@yopmail.com"))
