Cosmos Journeyer is the procedural universe running inside a web page that makes space exploration accessible for everyone.
The main website of the project is online at https://cosmosjourneyer.com/
The main deployment of the procedural universe can be accessed https://barthpaleologue.github.io/CosmosJourneyer/
The documentation is online at https://barthpaleologue.github.io/CosmosJourneyer/docs/
Additionally, the ARCHITECTURE.md file contains a big picture explanation of the architecture of the project.
To build it locally, run npm run docs and then npm run serve:docs to serve it at localhost:8081.
Contributions are welcome! There is too much to do for one person alone.
If you want to contribute, you will find guidelines and ideas here.
Developing Cosmos Journeyer is time-consuming and generates no revenue since it is free and open-source.

Every telluric planet and moon has a surface that can be explored by the player using a spaceship, or by foot!
Cosmos Journeyer allows to travel from one celestial body to another without any loading screen, giving the player a seamless experience while exploring.
Planet surfaces are filled with procedural vegetation and rocks and butterflies to make them feel more alive.
Cosmos Journeyer generates a virtually infinite amount of star systems that all have a star, often planets, and sometimes moons.
First, clone the repository and install the dependencies with pnpm install.
To build the web version of Cosmos Journeyer, run pnpm run build. Everything will be built in the dist folder.
Cosmos Journeyer can be built as a desktop application using Tauri!
First you will need a bazillion dependencies, here is a list of some of them if you are using a Debian base OS:
sudo apt install -y libwebkit2gtk-4.0-dev libgtk-3-dev libsoup2.4-dev libjavascriptcoregtk-4.0-dev librsvg2-dev libwebkit2gtk-4.0-dev libappindicator3-dev patchelfThen you can build the application with pnpm tauri build.
Thank you to all the people who have contributed to Cosmos Journeyer!
