A Runescape private server written in JavaScript running on the NodeJS chromium based engine.

I used a number of resources to get this running:

• https://explv.github.io/
• Graham from rune-server.ee: https://www.rune-server.ee/runescape-development/rs2-server/help/691785-player-update-protocol-could-use-little-guidance-p.html
• https://rsps.fandom.com/wiki/Data_Types
• https://rsps.fandom.com/wiki/317_Protocol
• Accidental cycle discovery: https://www.rune-server.ee/runescape-development/rs2-server/help/692079-opcode-decryption-how-approach.html
• Block-flag discovery: https://www.rune-server.ee/runescape-development/rs2-server/help/692068-block-flag-based-updating-0x10-render-failing.html
• Manually going through the client for packet sizes: https://www.rune-server.ee/runescape-development/rs2-server/informative-threads/692158-317-client-server-packet-list.html
• Update list mask consideration: https://www.rune-server.ee/runescape-development/rs2-server/help/692560-player-list-updating-should-consider-masks-loop.html

This project used Jest as the testing framework, coupled with ts-jest to enable strict type checks. Rather than a traditional test of each unit function, you'll notice the tests only apply to critical functions relating to the player. It is designed this way because we cannot test another players end-result.

To run the tests, simply run in node:

npm run test
