e-Plan Editor

A local-first electrical network editor for modeling, validating, and documenting electrical networks.

The app treats connectors, splices, nodes, segments, and wires as a graph, computes routes deterministically, and keeps canvas preferences and export outputs aligned with the current workspace state.

Live Demo & Status

• Production: https://e-plan-editor.onrender.com
• Hosting: Render Static Site (Blueprint via render.yaml)
• Current version: 1.14.8
• CI status: see the GitHub Actions badge above

Product

• Electrical modeling for connectors, splices, nodes, segments, and wires, with occupancy rules and wire-side connection / seal references.
• Automatic route computation, forced-route locking, and live wire-length recomputation after segment edits.
• Interactive 2D workspace with drag-and-drop nodes, zoom/pan controls, selectable segments, sub-network filtering, configurable callouts, wire-linked pin highlighting, and quick navigation between Modeling, Analysis, Statistics, Harness, and Settings.
• Connector and splice callouts with tabular wire details, optional wire-name columns, draggable positions, and catalog connector drawings when a physical layout was edited.
• Catalog-backed connector physical layout editor with reusable way geometry, keying features, shell shape controls, and physical connector analysis views.
• Harness assembly workflows for multi-network grouping, master connector references, inter-harness connector links, saved assembly graphs, current-network functional graphs, and contextual assembly help.
• Analysis workflows with targeted Go to actions, including navigation from Node analysis to Segment analysis, from Segment analysis to Wire analysis, and from connector analysis into physical views.
• Statistics workspace for active-network KPIs, manual multi-network comparison, wire-length metrics, section/color distributions, and utilization tables.
• Network-scoped catalog management with catalog-first connector flows, optional splice linkage, seeded starter items, usage analysis, and pricing context settings.
• Home workspace hub with Quick start actions, active-network context, changelog feed, and rich recent-change rows that can navigate back to changed objects when possible.
• Themed toast notifications for important workspace actions, including undo/redo and connector/splice occupancy changes.
• Export tooling for operational handoff:
  • SVG / PNG network-plan export with optional frame and metadata cartouche
  • BOM CSV export with pricing context and a dedicated Wire terminations section
  • wire CSV export with explicit begin/end connection and seal reference columns
• Network metadata authoring for export identity: creation date, author, project code, logo URL, and export notes.
• Local-first persistence so workspace state, settings, and export preferences survive reloads.
• Validation center with grouped issues, issue navigation, and catalog integrity checks.
• Built-in onboarding flow plus contextual help entry points to guide first-time usage.
• Accessibility-oriented interactions across dialogs, tables, keyboard navigation, and assistive-technology semantics.
• Theme, language, canvas, export, and onboarding preferences persisted per workspace.
• PWA support with install prompt, offline shell, and update readiness in production.

Technical Overview

• React 19 + TypeScript in strict mode.
• Vite for dev, preview, and production builds.
• Domain/state split:
  • src/core holds graph, routing, layout, and domain primitives.
  • src/store holds reducers, selectors, and action orchestration.
  • src/app holds screen composition, controller wiring, and UI modules.
• Persistence and portability:
  • local storage uses versioned schema migrations
  • import/export payloads are normalized and guarded against unsupported future versions
  • storage failures surface visible runtime warnings instead of silently corrupting state
• Test and quality stack:
  • Vitest + Testing Library for unit and integration coverage
  • Playwright for E2E smoke coverage
  • ESLint for linting
  • explicit quality gates for UI modularization, timeout governance, store modularization, segmented test ownership, and PWA artifacts
• Delivery workflow:
  • Logics-backed request/backlog/task tracking under logics/
  • CI runs the same blocking validation pipeline locally and in GitHub Actions

AI Agent Workspace

The Modeling AI Agent workspace supports controlled, reversible AI-assisted plan edits. The agent is not allowed to patch raw application state. It receives scoped electrical-plan context, asks the configured provider for a structured plan change, then lets the app derive, validate, preview, and apply bounded operations through the same domain rules as manual Modeling.

Loading

Getting Started

Prerequisites

• Node.js 20+
• npm
• Python 3 with logics-manager available as python3 -m logics_manager

Install

npm ci
python3 -m pip install logics-manager

Run locally

Create local env values from the tracked template:

cp .env.example .env

Supported variables and defaults:

• APP_HOST=127.0.0.1
• APP_PORT=5284
• PREVIEW_PORT=5285
• E2E_BASE_URL=http://127.0.0.1:5284
• VITE_STORAGE_KEY=electrical-plan-editor.state
• optional local maintenance credentials: RENDER_API_KEY, RENDER_SERVICE_ID, OPENAI_API_KEY, GEMINI_API_KEY

Env fallback behavior:

• Invalid/empty APP_PORT or PREVIEW_PORT falls back to documented defaults.
• Invalid/empty E2E_BASE_URL falls back to http://{APP_HOST}:{APP_PORT}.
• Invalid/empty VITE_STORAGE_KEY falls back to electrical-plan-editor.state.
• Keep secrets out of VITE_* variables (they are client-visible at build/runtime).
• Non-VITE_* variables are for local tooling only and are not bundled into the client app.

npm run dev

Then open http://127.0.0.1:5284 (unless overridden).

Deployment

Render (Blueprint)

This repository includes a ready-to-use render.yaml for static hosting on Render.

1. Push your latest changes to GitHub.
2. In Render, create a new service with Blueprint from this repository.
3. Render will build with npm ci && npm run build and publish dist/.

Any static server

The app is a SPA and can be hosted from dist/ on any static server/CDN.

• Build: npm run build
• Serve over HTTPS in production (required for full PWA behavior).
• Configure SPA fallback rewrite to /index.html.

Logics Workflow

This repository uses the standalone logics-manager CLI for Logics workflow operations.

• python3 -m logics_manager flow ... creates, promotes, and finishes workflow docs.
• python3 -m logics_manager lint --require-status validates Logics document structure.
• python3 -m logics_manager audit ... checks workflow consistency.

Persistence Versioning

The app uses explicit versioned payload contracts for both local storage and network export files.

• Current schema versions:

  • local persistence: 3
  • network import/export file: 3

• Local workspace persistence:

  • primary key: configured VITE_STORAGE_KEY (default electrical-plan-editor.state)
  • backup key: <storage-key>.backup (written before destructive migration replacement or unsupported/failed payload fallback)
  • payload includes:
    • payloadKind
    • schemaVersion
    • appVersion
    • appSchemaVersion
    • timestamps + serialized state

• Network export/import files:

  • include explicit file schemaVersion + source metadata (appVersion, appSchemaVersion)
  • legacy file payloads are normalized on import
  • unsupported future file versions are rejected safely (no workspace mutation)

Migration authoring workflow (future schema evolution):

1. Add/adjust payload shape support in src/adapters/persistence/migrations.ts (local storage) and/or src/adapters/portability/networkFile.ts (file import/export).
2. Keep migration steps incremental and deterministic (vN -> vN+1), with a single entry point for runtime hydration/import.
3. Add regression fixtures/tests for:
   • legacy/unversioned payload
   • current payload
   • unsupported future version
   • malformed payload
4. Run the full validation pipeline (npm run ci:local).

Quality and CI

Primary validation commands:

npm run ci:blocking

Equivalent expanded command list:

python3 -m logics_manager lint --require-status
python3 -m logics_manager sync close-eligible-requests
git diff --exit-code -- logics/request
python3 -m logics_manager audit --legacy-cutoff-version 1.1.0 --group-by-doc --skip-ac-traceability
npm run lint
npm run typecheck
npm run quality:dependency-audit
npm run test:ci:segmentation:check
npm run quality:ui-modularization
npm run quality:ui-timeout-governance
npm run quality:store-modularization
npm run quality:exceljs-boundary
npm run test:ci:fast -- --coverage
npm run test:ci:ui
npm run test:e2e
npm run build
npm run quality:pwa

CI runs the same main blocking pipeline in .github/workflows/ci.yml on push and pull_request.

Additional non-blocking CI observability:

• coverage:ui:report for src/app/** coverage visibility
• test:ci:ui:slow-top for top-N slow UI test reporting
• bundle:metrics:report for main-chunk and total-gzip size visibility
• these signals are informational and do not replace blocking CI gates
• in CI, coverage:ui:report and test:ci:ui:slow-top are configured with if: success() so they run only when prior blocking steps pass
• in CI, bundle:metrics:report stays informational and runs only when the production build step succeeds

Segmented test contract:

• explicit lane ownership is defined in scripts/quality/run-vitest-segmented.mjs
• test:ci:segmentation:check verifies the lane contract and fails on drift
• CI uses test:ci:fast + test:ci:ui as required lanes; test:ci remains available as a full-suite local command

Form validation doctrine (current targeted scope):

• native HTML validation guards simple required/number constraints first (catalog, wire)
• inline custom errors remain for business and cross-field rules (catalog URL policy, uniqueness, endpoint/business integrity)

UI reliability note:

• explicit per-test UI timeout overrides are disallowed by default and enforced by npm run quality:ui-timeout-governance
• temporary exceptions, if strictly necessary, must be explicitly allowlisted in scripts/quality/check-ui-timeout-governance.mjs with rationale and retirement plan

Local E2E note:

• npm run test:e2e requires a Playwright browser install first (CI runs npx playwright install --with-deps chromium).

PWA caveats:

• Service worker registration is production-only (build/preview) and remains disabled during normal npm run dev.
• Install prompt availability depends on browser capability and secure context (https or localhost).
• Offline behavior is guaranteed after the first successful online load of production assets.
