This pull request introduces a production-grade, security-hardened Docker Staging environment configuration for **NexusReader**, prepared directly from the `develop` branch. ### 🚀 Key Additions 1. **`docker-compose.stage.yml`**: - Deploys five isolated containers (`nexus-web-stage`, `nexus-db-stage`, `nexus-qdrant-stage`, `nexus-neo4j-stage`) inside a dedicated `nexus-stage` bridge network. - Sets non-conflicting port mappings to allow staging to run concurrently with other environments on the same host (e.g., Web on `5080`, Postgres on `5438`, Neo4j HTTP on `7488`). - Configures robust container healthchecks (`curl` for Qdrant, `wget` for Neo4j, `pg_isready` for Postgres). - Maps dedicated named persistent volumes for databases (`pgdata_stage`, `qdrant_stage_data`, `neo4j_stage_data`) to prevent data loss. - Maps separate persistent volumes specifically for dynamic web uploads (`stage_www_uploads` for EPUBs, `stage_www_covers` for covers) without overriding the compiled static web client files. 2. **`.env.stage.template`**: - A clean deployment environment template providing a blueprint of all variables. - Copied to `.env.stage` locally during deployment to inject secrets securely. - Mandates a secure `NEXUS_ADMIN_PASSWORD` (checked by `DbInitializer` for staging/production builds). 3. **`.gitignore`**: - Explicitly ignores local environment configurations (such as `.env.stage`) to prevent accidentally committing credentials, while keeping the `.env.stage.template` tracked. --- ### 🧪 Verification Performed - **Docker Compose Validation**: Ran `docker compose -f docker-compose.stage.yml --env-file .env.stage config` successfully with zero configuration or parsing errors. - **Solution Compilation**: Ran `dotnet build NexusReader.slnx --no-restore` from root — **SUCCESS** with `0` compile errors. - **Automated Tests**: Ran `dotnet test --no-restore` — **SUCCESS** (all 20/20 unit tests passed). --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #67 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
📖 Nexus Reader
Nexus Reader is a state-of-the-art, cross-platform Blazor .NET 10 immersive e-book reader, powered by Native AOT, Clean Architecture, CQRS, and interactive D3.js Relationship Graphs built on vector-based AI semantics.
✨ Features & Architecture Highlights
📁 Ingestion & Description persistence
- Extracted and persistent book descriptions from EPUB package metadata during book ingestion.
- The
Descriptionfield propagates cleanly from theEbookentity through Mapster toLastReadBookDtoandUserProfileDto.
🔗 Deep-Link Routing
- Implemented deep-link route activation:
/reader/{bookId}?chapter=N. - Allows instant resume of reading session coordinates and loads the specific chapter chapter directly via URL query parameters.
🛡️ Downstream AI Resilience
- Standard resilience engine in
DependencyInjection.csutilizing the Polly package (ai-retry). - Automatically intercepts, handles, and retries on both rate-limits (
429 Too Many Requests) and downstream capacity overloads (503 ServiceUnavailable/high demand).
⚙️ Concurrent Request Deduplication
- Multi-client InteractiveAuto Blazor circuit synchronization is backed by a thread-safe active task registry in
KnowledgeServicewhich ensures that identical concurrent requests await a single shared task instance, eliminating redundant LLM queries.
🛠️ Build & Verification Gate
Ensure the dotnet workload matches the active SDK, and compile the full solution utilizing:
dotnet build NexusReader.slnx --no-restore
Run test suite:
dotnet test --no-restore
