Hi, i Make a project called Evekarma.com, in less than 10 hours (not much code anyway). This is not pretty but have some interesting features. For cookies and debugging reasons, i am using two domains for manage it. Evepanel.com for create and auth your characters, and evekarma.com for checking your dashboard.
I suggest you dont use hotmail /live / outllok mails or you dont receive the code for your account. I suggest you use firefox, i dont test in chrome or edge yet. You MUST WAIT when is retrieveing the esi information from evepanel.com when you authorize your char.
This is a migration of part of my personal character manager. I suggest stringly try with six charactersat least ( 2 accounts ) and authorize the six chars and crete two eve panels (my terminology for three slots in your account)
Please remember i do it in less than 10 hours and is aprox 3000 lines of code (must of it is the panels, 500 for the auth and saving).
