UrsaMU is a MUSH-like server written in Typescript. It is designed to be a modern, and extensible MUSH-like server.

A MUSH is a text-based, multi-user, real-time virtual environment. It is a descendant of MUDs, which were the precursors to modern MMORPGs. MUSHes are designed to be highly extensible, and are often used for role-playing games, or social environments.

A MUSH-like is a server that is similar to a MUSH, but is not a MUSH. UrsaMU is a MUSH-like because it is not a MUSH, but it is similar to a MUSH.

To start the server in 'production' mode, make sure you have node installed, I suggest NVM, and then from the ursamu folder run:

git clone https://github.com/ursamu/ursamu.git
cd ursamu
./pup

To start the Ursamu server, you can use the following command:

./pup

To stop the Ursamu server, you can use the following command:

./pup terminate

It is easy to run the game under docker:

git clone https://github.com/ursamu/ursamu.git
cd ursamu
sudo docker-compose up -d

The game database will be exported to the data/ directory on the host filesystem, for easy backups.

Deno on ARM can be finicky right now. Here's a workaround:

git clone https://github.com/LukeChannings/deno-arm64.git deno-arm
cd deno-arm
sudo docker build -t deno-arm
cd ..
git clone https://github.com/ursamu/ursamu.git
cd ursamu
echo "BASE=deno-arm" > .env
sudo docker-compose up -d
