Tech Library

Tech Library is a modular, source-backed reference for modern web, app, and systems development. The Danish PWA serves layered English technical entries for readers at every experience level. Official-source monitoring proposes changes; a human editor always reviews them before publication.

Included

32 curated starter topics across web, frontend, backend, data, mobile/desktop, DevOps, testing/observability, and security
faceted browsing and SQLite FTS5 search
immutable revisions, publication pointers, rollback, and claim-level provenance
integrated editorial workspace with secure session and CSRF protection
idempotent monitoring of official sources with a daily scheduler and manual trigger
installable React/Vite PWA, Fastify API, SQLite/Drizzle data layer, and independent worker
Docker Compose deployment, health checks, persistent data, backup and restore guidance

Quick start

Requirements: Node.js 22+ and npm 10+.

npm install
npm run db:migrate
npm run db:seed
$env:ADMIN_PASSWORD_HASH = npm run --silent password:hash -w @tech-library/api -- "development password"
$env:SESSION_SECRET = "replace-this-with-a-long-random-development-secret"
npm run dev

Open http://localhost:5173. The API runs on port 3001. Local content is stored under data/ and is intentionally ignored by Git.

Commands

Command	Purpose
`npm run dev`	Run web, API, and source worker
`npm run check`	Type-check, test, and build every workspace
`npm run db:migrate`	Apply idempotent SQLite migrations
`npm run db:seed`	Add the curated starter catalog
`docker compose up -d --build`	Build and run the production topology

Repository structure

apps/web       React, Vite, Radix UI, TanStack Query, Zustand, PWA
apps/api       Fastify REST API, editorial policy, authentication
apps/worker    Official-source monitoring and structured findings
packages/contracts  Shared Zod schemas and public TypeScript types
packages/database   Drizzle schema, migrations, seed catalog
deploy         Reverse-proxy configuration
docs           Architecture decisions and operations
scripts        Backup and restore helpers

See architecture and operations for system boundaries and production guidance.

Editorial flow

The worker fetches enabled official sources and normalizes volatile page content.
A new fingerprint produces one deduplicated finding; failures only update source health.
An administrator reviews the source and creates an immutable draft revision.
A revision must be approved before it can be published.
Publication updates the active pointer and search index in one transaction; rollback selects a prior approved revision.

Development policy

Use short feature branches and focused Conventional Commits. Tests and documentation belong in the same change as the behavior they describe. Comments should explain decisions or non-obvious constraints rather than restating code.
