underpost

Underpost Platform

Underpost is an platform for application delivery, from infrastructure to runtime. The underpost npm package is its CLI toolchain surface.

The project covers:

• Bare metal provisioning on Rocky Linux 9.
• Kubernetes / K3s / kubeadm / LXD workflows for production, edge, and isolated workloads.
• GitHub OSS repository flow — clone, pull, push, commit, release, and CI integrations as first-class CLI subcommands.
• CI/CD orchestration — GitHub Actions integrations, container builds, multi-environment deployments.
• Static build + PWA delivery — every deploy ships as an installable Progressive Web App with Workbox-based offline support.
• Cloudinary-backed static asset flow for image/asset delivery.
• ERP/CRM-style PWA base applications as the default workload.
• Cyberia — a dedicated MMO extension built on top of the platform, with its own content backend (engine-cyberia), authoritative simulation runtime (cyberia-server), and presentation runtime (cyberia-client).

See Detailed platform doc.

Architectural roles (Cyberia stack)

When the platform is hosting the Cyberia MMO extension, three independent runtime processes participate. Their boundaries are non-overlapping.

Process	Role
engine-cyberia (Node.js)	Content authority: maps, object layers, atlas/asset metadata, world configuration, persistence, validation, gRPC + REST data services, editor backend, asset distribution.
cyberia-server (Go)	Authoritative simulation runtime: tick advancement, AOI replication, input command processing, snapshot generation.
cyberia-client (C → WebAssembly)	Presentation runtime: rendering, UI, input capture, prediction, reconciliation, interpolation, client-side presentation defaults.

The ecosystem is playable only when all three are running and healthy. Each service is supervised independently and owns its own monitor/reconnector. If any one is unhealthy, the game enters standby and resumes automatically once all three are healthy again.

See detailed Cyberia architecture.
