# SolaceScan Explorer - Tiered Architecture

## 🚀 Quick Start - Complete Deployment

**Execute this single command to complete all deployment steps:**

```bash
cd ~/projects/proxmox/explorer-monorepo
bash EXECUTE_DEPLOYMENT.sh
```

## What This Does

1. ✅ Tests database connection
2. ✅ Runs migration (if needed)
3. ✅ Stops existing server
4. ✅ Starts server with database
5. ✅ Tests all endpoints
6. ✅ Provides status summary

## Manual Execution

If the script doesn't work, see `START_HERE.md` for step-by-step manual commands.

## Frontend

- **Production (canonical target):** the current **Next.js standalone frontend** in `frontend/src/`, built from `frontend/` with `npm run build` and deployed to VMID 5000 as a Node service behind nginx.
- **Canonical deploy script:** `./scripts/deploy-next-frontend-to-vmid5000.sh`
- **Canonical nginx wiring:** keep `/api`, `/api/config/*`, `/explorer-api/*`, `/token-aggregation/api/v1/*`, `/snap/`, and `/health`; proxy `/` and `/_next/` to the frontend service using `deployment/common/nginx-next-frontend-proxy.conf`.
- **Legacy fallback only:** the static SPA (`frontend/public/index.html` + `explorer-spa.js`) remains in-repo for compatibility/reference, but it is not a supported primary deployment target.
- **Architecture command center:** `frontend/public/chain138-command-center.html` — tabbed Mermaid topology (Chain 138 hub, network, stack, flows, cross-chain, cW Mainnet, off-chain, integrations). Linked from the SPA **More → Explore → Visual Command Center**.
- **Legacy static deploy scripts:** `./scripts/deploy-frontend-to-vmid5000.sh` and `./scripts/deploy.sh` now fail fast with a deprecation message and point to the canonical Next.js deploy path.
- **Frontend review & tasks:** [frontend/FRONTEND_REVIEW.md](frontend/FRONTEND_REVIEW.md), [frontend/FRONTEND_TASKS_AND_REVIEW.md](frontend/FRONTEND_TASKS_AND_REVIEW.md)

## Architecture

- **Track 1 (Public):** RPC Gateway - No authentication required
- **Track 2 (Approved):** Indexed Explorer - Requires authentication
- **Track 3 (Analytics):** Analytics Dashboard - Requires Track 3+
- **Track 4 (Operator):** Operator Tools - Requires Track 4 + IP whitelist

## Configuration

- **Database User:** `explorer`
- **Database Password:** `L@ker$2010`
- **RPC URL:** `http://192.168.11.250:8545`
- **Chain ID:** `138`
- **Port:** `8080`

## Reusable libs (extraction)

Reusable components live under `backend/libs/` and `frontend/libs/` and may be split into separate repos and linked via **git submodules**. Clone with submodules:

```bash
git clone --recurse-submodules <repo-url>
# or after clone:
git submodule update --init --recursive
```

See [docs/REUSABLE_COMPONENTS_EXTRACTION_PLAN.md](docs/REUSABLE_COMPONENTS_EXTRACTION_PLAN.md) for the full plan.

## Testing

- **All unit/lint:** `make test` — backend `go test ./...` and frontend `npm test` (lint + type-check).
- **Backend:** `cd backend && go test ./...` — API tests run without a real DB; health returns 200 or 503, DB-dependent endpoints return 503 when DB is nil.
- **Frontend:** `cd frontend && npm run build` or `npm test` — Next.js build (includes lint) or lint + type-check only.
- **E2E:** `make test-e2e` or `npm run e2e` from repo root — Playwright tests against https://blockscout.defi-oracle.io by default; use `EXPLORER_URL=http://localhost:3000` for local.

## Status

✅ All implementation complete  
✅ All scripts ready  
✅ All documentation complete  
✅ Frontend: C1–C4, M1–M4, H4, H5, L2, L4 done; H1/H2/H3 (escapeHtml/safe href) in place; optional L1, L3 remain  
✅ CI: backend + frontend tests; lint job runs `go vet`, `npm run lint`, `npm run type-check`  
✅ Tests: `make test`, `make test-e2e`, `make build` all pass  

**Ready for deployment!**
