What owopserver does

OWOP Server is a custom backend implementation designed specifically for the Ourworldofpixels (OWOP) client. Written entirely in Node.js, it was developed to solve the severe lag and performance issues commonly found in the official server and other JavaScript-based alternatives. The project focuses heavily on optimizing critical pathways, such as chunk loading and network communication, to handle large numbers of concurrent pixel updates efficiently. It aims to achieve performance parity with C++ implementations while providing support for all client tools, moderator commands, world properties, and HTTP API integrations.

This server is intended for community managers, server operators, and JavaScript developers looking to host or modify an Ourworldofpixels environment. Users should be comfortable configuring Node.js applications and managing environment variables.

  • Node.js architecture: Built entirely in Node.js, providing an accessible codebase for web developers to modify and extend.
  • Performance optimization: specifically engineered and benchmarked to handle high-frequency chunk loading and pixel updates without stuttering.
  • Complete feature parity: Supports all standard OWOP tools, user commands, admin actions, and world properties out of the box.
  • Integrated moderation tools: Includes built-in support for banning, captcha verification, and moderator-specific commands.
  • HTTP API support: Exposes a functional HTTP API for external integrations, mirroring the official server's capabilities without the secret messages.

Where teams use it

Private community hosting

Community leaders deploy the server to host private, lag-free pixel art canvases for dedicated groups or events.

High-traffic pixel events

Administrators utilize the optimized chunk loading to support hundreds of users drawing simultaneously during viral internet events.

Custom gameplay modification

JavaScript developers fork the repository to easily inject custom rules, tools, or bots into the OWOP ecosystem.

Moderated public servers

Operators leverage the built-in captcha and banning tools to maintain clean, troll-free public pixel worlds.

Getting started: yarn install && yarn start

README

main branch

OWOP Server

This is a server for https://ourworldofpixels.com. It's written in Node.js and designed to be more performant than other js OWOP servers out there.

How to use

  1. Install Node.js and Yarn (recommended to use Node 18.17.0, and the latest version of Yarn, 1.22.19 as I'm writing this)
  2. Clone or download this repo
  3. Rename .env.example to .env, then configure the variables inside of it according to the comments
  4. If you wish, configure some other server properties in config.json
  5. Run yarn install from a command prompt in the server directory
  6. Run yarn start to start the server
  7. If using some weird fucked up server config u can specify a location to symlink commands to relative to repo src dir in config.json

(7a) - in config.json do this:

"cmdPathOverride": {
	"src": "path/to/repo/src/dir"
}

About

I made this mostly as a fun project to see if I could. I've coded in OWOP for a decent amount of time, but only ever from the client's side. Seeing that the official server often had issues with lag and other OWOP servers I've found also did, I set out to write a better server that would have a lot less of those issues. A decent amount of benchmarking went into this to optimize some of the more heavily used parts of the server, such as chunk loading. Of course, being in an interpreted language, there is going to be some slowdown compared to the official server which is in C++. Hopefully other optimizations I've made can make up for that difference, or at least get close.

This includes: support for all tools, all user and moderator commands, most world properties, banning, captcha, HTTP api without some of the secret messages, and a good portion of the admin commands.
