A small React web app for visualizing a personal daily-habit scoring system tracked in a Google Sheet.

SECCEWLMMS is an acronym for the ten things scored each day — Sleep, Eat, Clean, Curtail (internet), Exercise, Work, Laugh, Meditate, Music, Socialize. Each gets a 0–10 score with a weight, producing a single weighted daily percentage. The sheet also records which sports/exercises were done that day.

Turn a habit-tracking spreadsheet into a browsable dashboard:

• See every day's raw scores in a sortable / filterable table.
• Watch trends over time (day / week / month / year) for the overall score and any individual metric.
• See which sports you do most, sliceable by date range and weekday.

The Google Sheet stays the single source of truth — the app only reads from it.

• /rawdata — the full SCORES table. Click any header to sort; filter the text columns (date, weekday, sports, comment).
• /analytics
  • Score timegraph — a thick black line for the overall score (plotted on a 0–10 scale), with optional dotted colored lines per metric. Switch the x-axis between day/week/month/year, filter by date range and weekday/weekend.
  • Sport barchart — one bar per sport, ordered most→least frequent. Filter by date range and toggle specific weekdays (e.g. "all Mondays and Tuesdays in a range").
• /definitions — the list of sport categories plus the ten scoring metrics and their weights.
• Pastel / retro styling; current page highlighted in blue.

Browser (React + Vite)  →  GET /api/scores , /api/selector  →  Local Node API (Vite middleware)
                                                                  │ Sheets API v4 + service account (JWT, read-only)
                                                                  ▼
                                                        Google Sheet (PRIVATE)

Google service accounts authenticate by signing a JWT with a private key. That must happen server-side, so a tiny Vite middleware plugin (vite.config.js + server/sheets.mjs) does the auth and proxies read-only sheet data to the frontend. The private key never reaches the browser, and the sheet can stay fully private (shared only with the service account). The auth is dependency-free — it uses Node's built-in crypto and fetch.

Create a Google Sheet with two tabs:

• SCORES — columns in this order: Date, Wkd (weekday abbreviation like Mon), then the 10 metric scores, then % (weighted total like 82.14%), then X1, X2, X3 (sports done that day), and an optional Comment. See example.txt and explanation.txt.
• Selector — a single column with header VALUES listing the valid sport names. See selector_eaxmples.txt.

If your layout differs, adjust the column mapping in src/lib/transform.js and the metric list in src/lib/metrics.js.

1. In the Google Cloud Console, create (or pick) a project.
2. Enable the Google Sheets API.
3. Create a service account, then create a JSON key for it and download it.
4. Save that file as useraccount.json in the project root. (It is git-ignored — see useraccount.example.json for its shape.)
5. Share your Google Sheet with the service account's email (the client_email field in the JSON) as a Viewer. The sheet does not need to be public.

cp .env.example .env
# edit .env and set SHEET_URL to your sheet's URL

npm install
npm run dev

Open http://localhost:5173. Vite serves the app and the /api/* endpoints together — one process, no separate backend to run.

React, Vite, React Router, Recharts, date-fns. Node 18+ recommended (uses global fetch).

• useraccount.json (your private key) and .env (your sheet URL) are git-ignored — never commit them.
• The sample data in example.txt, explanation.txt, and selector_eaxmples.txt is illustrative; replace it with your own or remove it.
• The app is read-only and intended to run locally.
