## Metarhia tech stack documentation



Metarhia is the **first** technology stack for Node.js scaled with **threads**, offering ultra-lightweight workload **isolation**.

It is optimized for **high-intensive** data exchange, rapid development, **clean architecture**, and easily understandable domain-specific code.

Metarhia provides an all-in-one solution for a **reliable** and **efficient backend**. It supports network communication with web and mobile clients, offers a protocol-agnostic **API**, run-time type validation, real-time and in-memory data processing, and both **stateful** and **stateless** services.



**Weaknesses**: not suitable as content publishing platforms, including blogs and SEO-focused websites, as well as server-side rendering and serving static content.



**Strengths**: enhanced security and architecture suitable for enterprise-level applications, long-lived WebSocket connections to minimize latency and handshake overhead, and no third-party dependencies.

## Short feature list



- **API auto-routing** calls to `endpoint` for rapid API development (no need to add routes manually)

- **API concurrency**: request execution timeout and execution queue with both timeout and size limitations

- **Schemas** for API contract, data structures validation, and domain models

- **Application server** supports different API styles: RPC over AJAX and over Websocket, REST, and web hooks

- **Multiple protocols** support: HTTP, HTTPS, WS, WSS

- **Auto loader** with `start` hooks, namespace generation for code and dependencies

- **Live reload** of code through filesystem watch

- **Graceful shutdown** with `stop` hooks

- **Minimal dependencies** and reduced code size

- **Layered architecture**: api, domain logic, data access layer, and system code layer (hidden)

- **Code sandboxing** for enhanced security and execution context isolation

- **Code protection**: reference pollution prevention, prototype pollution prevention

- **Multi-threading** for CPU utilization and execution isolation

- **Load balancing** for simple scaling with redirection to multiple ports

- **Caching**: in-memory caching for APIs and static files

- **Configuration**: environment-specific application settings

- **Database access** layer compatible with PostgreSQL with SQL-injection protection

- **Persistent sessions** with authentication, groups, and anonymous sessions

- **Buffered logging** (lazy write) with log rotation (keep logs N days) and console interface

- **Testing**: integrated node.js native test runner and table-test support

- **Inter-process** communication and shared memory used for state management

- **File utilities**: upload, download, support for partial content and streaming

- **Task Management**: scheduled task execution at specific intervals or certain times



## TODO list



Those features will be implemented in nearest future (3-6 months):



- Server health monitoring

- Database migrations

- State synchronization mechanism with transactions and subscription

- Multi-tenancy support
