A FLAME analysis is a container that travels to the data. Institutions each run a node; Hub is the centre that decides what runs where — it builds the analysis image, ships it to the nodes that joined a project, and collects the results, without ever seeing a row of the underlying data.

This monorepo is the central half: five backend services, a Nuxt frontend, 19 shared TypeScript libraries, and the documentation site.

Quick start

Requires Node.js 24, npm, and Docker. Running the backend locally also expects Authup (OAuth2), Redis, RabbitMQ, and MySQL or PostgreSQL.

npm ci # install
npm run build # build all packages (Nx, dependency-aware)
npm run test# run the test matrix
npm run lint # lint

docker compose up -d # MySQL + Postgres
npm run dev --workspace=apps/server-core # Core API
npm run dev --workspace=apps/client-ui # Nuxt frontend
npm run dev --workspace=docs # Documentation site

Every entity endpoint answers with a { data, meta } envelope, and every query-capable GET publishes the vocabulary it accepts under meta.schema — so a client never has to read server source to build a valid query.

Services

Each backend service follows the same hexagonal (ports & adapters) architecture and ships in the shared privateaim/hub Docker image, selected at startup with SERVICE=<name>.

Service	Responsibility
server-core	Main REST API — analyses, projects, nodes, registries
server-core-worker	Background worker — Docker image build & distribution
server-storage	File and object storage, on MinIO / S3 or the filesystem
server-telemetry	Log aggregation and events, backed by VictoriaLogs
server-messenger	Durable store-and-forward message broker
client-ui	Nuxt 4 web application

Packages

Shared libraries, published to npm as @privateaim/*.

Foundation

Package	Responsibility	Version
kit	Crypto, domain events, permissions, realms
errors	HubError, typed subclasses, code → HTTP-status mapping

Domain kits

Models, contracts and typed clients, one set per service area.

Package	Responsibility	Version
core-kit	Domain models and types for the core service
core-http-kit	HTTP client for the core API
core-realtime-kit	WebSocket event contracts for the core API
storage-kit	Storage domain types and HTTP client
telemetry-kit	Telemetry domain types and validators
messenger-kit	Messenger contracts and crypto types
messenger-http-kit	HTTP client for the messenger broker

Server kits

Building blocks shared across the backend services.

Package	Responsibility	Version
server-kit	Logging, auth, AMQP, Redis, dependency injection
server-db-kit	TypeORM utilities and migration support
server-http-kit	HTTP middleware and OpenAPI generation
server-realtime-kit	Socket.io server helpers
server-storage-kit	Storage service components
server-telemetry-kit	Telemetry components and Winston transport
server-core-worker-kit	Worker task definitions
server-test-kit	Shared test fakes and helpers

Client

Package	Responsibility	Version
client-vue	Vue 3 component library
client-vue-theme	vuecs-based theme — design tokens and chrome

Built with

FLAME Hub runs on a stack of open-source libraries maintained by the same author: Authup (identity and access), Routup (HTTP routing), Hapic (HTTP clients), validup (validation), ilingo (i18n), and vuecs (Vue components and theming).
