The Node.js specific rules for Eslint were deprecated in favour of the
node plugin for Eslint. Add node plugin for eslint and switch over to
using its rules, fixing any issues detected.
Move the depenedncies needed to run the tests into test/package.json and
manage it using lerna. This should make it easier to selectively
install only what's needed to run the software.
Simplify the the way markdown files are formatted to make them easier to
author without editors that do auto line breaking, and make the diffs
from them simpler to read.
Add authentication plugin that does a simple challenge response protocol
to verify that the player trying to log in is who they claim to be. The
process goes as follows:
1. A player code is generated for a player that wants to log in and is
displayed in-game.
2. The player code is input into the web interface and the master
generates a verification code as a challenge back along with a token.
3. The player inputs the verification code in-game and is logged in to
the web interface in doing so.
To do the actual login the web interface polls a verify endpoint every 2
seconds until the code has either been verified or expired. The
challenge comes from being unable to control the verification code and
having to input it as a player logging into one of the servers in order
to login.
Some additional steps are taken in order to increase the difficulty for
an attacker to subvert the challenge:
- The login process must be started from in-game.
- Generated codes are only valid for a limited timespan which is
configurable and 2 minutes by default.
- The verification code comes with a token that only works with one
player code and verification code combo and must be provided to pass
validation.
