Question 1

How to add new geography game modes to Posio?

Accepted Answer

You need to extend the Django models and views using GeoDjango, update the database with spatial data, and modify HTMX templates for the frontend. The existing code structure for cities and flags can serve as a reference, but it requires Python and web development expertise.

Question 2

Can Posio be deployed on AWS or Heroku?

Accepted Answer

Yes, but it requires additional configuration. On AWS, use EC2 with Elasticache for Redis and ensure spatial database support like PostGIS on RDS. Heroku might need buildpacks for GeoDjango and Redis, with careful handling of WebSocket connections.

Question 3

What are the system requirements for self-hosting Posio?

Accepted Answer

You need a server with Python 3.12+, Redis installed and running, and a spatial database such as Spatialite or PostGIS. For moderate player loads, a VPS with at least 1GB RAM should suffice, but scaling up requires more resources.

Question 4

How does Posio handle real-time updates compared to using Socket.io?

Accepted Answer

Posio uses Django Channels, which is Django-native and integrates well with the ORM, but it may have different scalability patterns than Node.js-based Socket.io. Channels is easier for Django developers but might require more tuning for high concurrency.

Question 5

Is Posio suitable for large-scale classroom use with hundreds of students?

Accepted Answer

For small to medium groups, it works well, but for hundreds of concurrent players, you'd need to optimize Redis connections and database queries. The out-of-the-box setup isn't designed for massive scale without performance adjustments.

Question 6

Posio vs other open-source geography games like Seterra?

Accepted Answer

Posio focuses on real-time multiplayer and self-hosting with a modern tech stack, while Seterra is primarily single-player and web-based with simpler setup. Posio offers more customization for developers but requires more maintenance.

Question 7

How to customize the map styles in Posio?

Accepted Answer

Map styles are controlled by Leaflet; you can modify the frontend JavaScript or CSS to change tilesets or visuals. However, the README doesn't provide specific instructions, so you might need to explore the codebase or Leaflet documentation.
