Description

I created a login page and add form validation functionality.

Note that it doesn't check whether "Node IP" is valid for now. Though I found the regex pattern to check valid IP address or hostname, it looks a bit complicated, but I would like to use this regex pattern for "Node IP" validation if it is ok.

• regex - Regular expression to match DNS hostname or IP Address? - Stack Overflow

How to check

1. npm install to install newly added dependencies.
2. npm run dev
