@lindorm/monorepo

A TypeScript library ecosystem for building secure, scalable Node.js services — covering cryptography, persistence, messaging, event sourcing, HTTP/WebSocket, and the small utilities that hold them together.

The monorepo is ESM-only and targets Node.js >= 24.13.0. Every package ships native ESM, native (TC39 stage 3) decorators where applicable, and is published independently to npm under the @lindorm scope.

Disclaimer

This is a monorepo I primarily use to learn new technologies and test ideas. Programming (and especially TypeScript on Node.js) is my special interest — my passion. I hold every package to the highest possible quality standards, because that's how I am as a person. However, there are only so many hours in a day, so while some packages are production ready (forks of pylon, logger, conduit, proteus, and amphora are running in production), not all of them are.

Highlights

• Cryptography suite — JOSE tokens (JWT / JWS / JWE), AKP / EC / OKP / RSA / oct signing kits (including post-quantum ML-DSA / FIPS 204), AES, Argon2id passwords, and an Amphora key vault with JWKS + OIDC discovery.
• One ORM, six drivers — Proteus models run unchanged against PostgreSQL, MySQL, SQLite, MongoDB, Redis, or an in-memory store, with field-level encryption via Amphora.
• One messaging API, five brokers — Iris speaks memory, RabbitMQ, Kafka, NATS, and Redis Streams behind a single decorator-driven contract.
• Event sourcing & CQRS — Hermes ties Proteus and Iris together for aggregates, sagas, views, queries, timeouts, GDPR-friendly @Forgettable() event-payload encryption, and event-stream checksum verification.
• HTTP & WebSocket — Pylon for servers (Koa + Socket.IO), Conduit for middleware-based HTTP clients on Axios (retries, circuit breaking, rate limiting, request deduplication, response caching, OAuth2 client credentials, DPoP, Zod validation), and Zephyr for type-safe Socket.IO clients in Node.js and React.
• Production-grade plumbing — circuit breakers, retry/back-off, interval workers, structured Winston-backed logging, Zod-validated runtime config, and Docker-Compose-aware test orchestration.
• Modular & tree-shakeable — every package is independently published, ESM-only, and shipped with full TypeScript types and TC39 stage-3 decorators where they apply.

Installation

Pick the packages you need — each is published independently:

npm install @lindorm/aegis @lindorm/amphora @lindorm/logger
npm install @lindorm/proteus pg
npm install @lindorm/iris kafkajs
npm install @lindorm/pylon
npm install @lindorm/hermes

Driver and feature peers (databases, brokers, encryption helpers) are listed in each package's README and only need to be installed for the drivers / features you use.

Working in the monorepo

Prerequisites

• Node.js >= 24.13.0
• npm 10+ (workspaces)
• Docker + Docker Compose (only for integration suites in iris and proteus)

Setup

git clone https://github.com/lindorm-io/monorepo.git
cd monorepo
npm install
npm run build

Common scripts

Script	What it does
npm run build	Build every package via Lerna.
npm run typecheck	Loose typecheck across all packages.
npm run lint	ESLint on packages/*/src/ plus the cadence-script audit.
npm test	Unit suites everywhere, then integration suites under composed (boots Docker services).
npm run test:unit	Unit suites only (no Docker).
npm run test:integration	Integration suites only (boots Docker services).
npm run test:weekly	Long-running suites that only run on the weekly schedule.
npm run sync:peers	syncpack lint — verify peer-dep ranges across packages.
npm run release	lerna publish (maintainer use).

Tests are powered by Vitest 4 with cadence-driven configs (unit, integration, weekly). Only iris and proteus ship integration suites — everything else is pure unit tests. Run a single package's tests by cd packages/<name> && npm test.
