Logga Documentation Overview

Shared documentation for the Logga product, codebase, API surface, and operating model.

Logga is a real-time event tracking product with three main surfaces:

  • a TypeScript backend that ingests events and drives sessions, rules, notifications, and reports
  • a Next.js dashboard for operators and workspace members
  • a native SwiftUI iOS app for the personal, on-device control room experience

This documentation is designed to be:

  • modular: each topic lives in its own Markdown file
  • reusable: the same source files can be read in raw .md form or rendered as HTML
  • maintainable: navigation is explicit and every page can be updated independently
  • shareable: the docs are written for both internal maintainers and adjacent projects

Core Product Concepts

Concept Meaning
Workspace Top-level customer container. Owns environments, projects, API keys, rules, reports, and memberships.
Environment Deployment slice inside a workspace. Current code guarantees at least production and sandbox.
Project Product or app slice inside an environment. Events and sessions are attached to a project.
Channel Named stream inside a project, such as payments, auth, or system.
Event Immutable telemetry record sent by API clients.
Session Multi-step process that can be updated over time and eventually completed, failed, or closed.
Rule Alert definition that evaluates event or absence conditions.
Notification Outbound alert generated from rules.
Report Scheduled aggregate over past events, optionally grouped or filtered.

Documentation Principles

1. Write for future maintainers

The target reader is someone who did not build the feature last week. Prefer naming things exactly as they exist in code and linking to the relevant docs page instead of hand-waving.

2. Keep pages focused

Do not turn one document into a dumping ground. If a topic grows into its own system, create a dedicated page and add it to docs/navigation.json.

3. Use examples aggressively

Logga is an API-driven product. Examples make docs useful. Prefer real payload shapes, real route names, and real workflow steps.

4. Update docs in the same change window

If a route, model, or workflow changes, update the relevant Markdown page before the context fades. The docs system is intentionally simple so updates are cheap.

Source Of Truth

These docs intentionally follow the code that exists today:

  • backend routes are registered in logga-backend/src/index.ts
  • core persistence models live in logga-backend/prisma/schema.prisma
  • the dashboard runs from logga-frontend
  • the iOS app lives in logga-app/logga/logga

If you notice drift between docs and code, fix the docs or explicitly note the mismatch in the page that is closest to the source.
