Hi

\"\n});\n```\n\n## Val Town Utility Functions\n\nVal Town provides several utility functions to help with common project tasks.\n\n### Importing Utilities\n\nAlways import utilities with version pins to avoid breaking changes:\n\n```ts\nimport { parseProject, readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n```\n\n### Available Utilities\n\n\n#### **serveFile** - Serve project files with proper content types\n\nFor example, in Hono:\n\n```ts\n// serve all files in frontend/ and shared/\napp.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\napp.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n```\n\n#### **readFile** - Read files from within the project:\n\n```ts\n// Read a file from the project\nconst fileContent = await readFile(\"/frontend/index.html\", import.meta.url);\n```\n\n#### **listFiles** - List all files in the project\n\n```ts\nconst files = await listFiles(import.meta.url);\n```\n\n#### **parseProject** - Extract information about the current project from import.meta.url\n\nThis is useful for including info for linking back to a val, ie in \"view source\" urls:\n\n```ts\nconst projectVal = parseProject(import.meta.url);\nconsole.log(projectVal.username); // Owner of the project\nconsole.log(projectVal.name); // Project name\nconsole.log(projectVal.version); // Version number\nconsole.log(projectVal.branch); // Branch name\nconsole.log(projectVal.links.self.project); // URL to the project page\n```\n\nHowever, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.\nIf you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page\nor by making an API request for it.\n\n## Val Town Platform Specifics\n\n- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: \"/place/to/redirect\" }})` instead of `Response.redirect` which is broken\n- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead\n- **AI Image:** To inline generate an AI image use: `

`\n- **Storage:** DO NOT use the Deno KV module for storage\n- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods\n- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified\n- **View Source:** Add a view source link by importing & using `import.meta.url.replace(\"ems.sh\", \"val.town)\"` (or passing this data to the client) and include `target=\"_top\"` attribute\n- **Error Debugging:** Add `` to HTML to capture client-side errors\n- **Error Handling:** Only use try...catch when there's a clear local resolution; Avoid catches that merely log or return 500s. Let errors bubble up with full context\n- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys\n- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser\n- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites\n- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and start the file with `/** @jsxImportSource https://esm.sh/react@18.2.0 */`\n- Ensure all React dependencies and sub-dependencies are pinned to the same version\n- **Styling:** Default to using TailwindCSS via `` unless otherwise specified\n\n## Project Structure and Design Patterns\n\n### Recommended Directory Structure\n```\n├── backend/\n│ ├── database/\n│ │ ├── migrations.ts # Schema definitions\n│ │ ├── queries.ts # DB query functions\n│ │ └── README.md\n│ └── routes/ # Route modules\n│ ├── [route].ts\n│ └── static.ts # Static file serving\n│ ├── index.ts # Main entry point\n│ └── README.md\n├── frontend/\n│ ├── components/\n│ │ ├── App.tsx\n│ │ └── [Component].tsx\n│ ├── favicon.svg\n│ ├── index.html # Main HTML template\n│ ├── index.tsx # Frontend JS entry point\n│ ├── README.md\n│ └── style.css\n├── README.md\n└── shared/\n ├── README.md\n └── utils.ts # Shared types and functions\n```\n\n### Backend (Hono) Best Practices\n\n- Hono is the recommended API framework\n- Main entry point should be `backend/index.ts`\n- **Static asset serving:** Use the utility functions to read and serve project files:\n ```ts\n import { readFile, serveFile } from \"https://esm.town/v/std/utils@85-main/index.ts\";\n \n // serve all files in frontend/ and shared/\n app.get(\"/frontend/*\", c => serveFile(c.req.path, import.meta.url));\n app.get(\"/shared/*\", c => serveFile(c.req.path, import.meta.url));\n \n // For index.html, often you'll want to bootstrap with initial data\n app.get(\"/\", async c => {\n let html = await readFile(\"/frontend/index.html\", import.meta.url);\n \n // Inject data to avoid extra round-trips\n const initialData = await fetchInitialData();\n const dataScript = ``;\n \n html = html.replace(\"\", `${dataScript}`);\n return c.html(html);\n });\n ```\n- Create RESTful API routes for CRUD operations\n- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:\n ```ts\n // Unwrap Hono errors to see original error details\n app.onError((err, c) => {\n throw err;\n });\n ```\n\n### Database Patterns\n- Run migrations on startup or comment out for performance\n- Change table names when modifying schemas rather than altering\n- Export clear query functions with proper TypeScript typing\n\n## Common Gotchas and Solutions\n\n1. **Environment Limitations:** \n - Val Town runs on Deno in a serverless context, not Node.js\n - Code in `shared/` must work in both frontend and backend environments\n - Cannot use `Deno` keyword in shared code\n - Use `https://esm.sh` for imports that work in both environments\n\n2. **SQLite Peculiarities:**\n - Limited support for ALTER TABLE operations\n - Create new tables with updated schemas and copy data when needed\n - Always run table creation before querying\n\n3. **React Configuration:**\n - All React dependencies must be pinned to 18.2.0\n - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files\n - Rendering issues often come from mismatched React versions\n\n4. **File Handling:**\n - Val Town only supports text files, not binary\n - Use the provided utilities to read files across branches and forks\n - For files in the project, use `readFile` helpers\n\n5. **API Design:**\n - `fetch` handler is the entry point for HTTP vals\n - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`\n\n",[],[212],{"_105":219,"_96":220,"_154":221,"_156":-5,"_157":140,"_158":222,"_160":22,"_107":223,"_101":32,"_163":188,"_165":224,"_166":22,"_167":-5,"_168":225,"_99":226},"ff57af06-f0c9-11f0-8caa-42dde27851f2","PLAN.md","ff57afba-f0c9-11f0-8caa-42dde27851f2",26,["D",1768341081095],"# Notion Life Tracker Plan\n\n## What we've built so far\n\n- A Notion database for blood sugar readings\n- A Val Town script that pulls the last 7 days of entries\n- Weekly stats (avg/min/max, completion rate, streak, badges)\n- A friendly email report sent on a schedule\n\n## Why this works well\n\n- We only query Notion for a small time window (fast even as Notion grows)\n- We compute the rollup once per week and send it as a summary\n- We can reuse the same pattern for other life areas (exercise, meals, goals)\n\n## Next step: store rollups in SQLite\n\nWe’ll store weekly rollups (badges, streaks, XP) in Val Town’s SQLite so we can:\n- build monthly and yearly summaries without re-reading Notion\n- compare across categories (e.g., blood sugar vs exercise)\n- keep a long-term history even if we rename Notion pages\n\n## Proposed storage shape\n\n- `weekly_rollups`: one row per category per week\n- `badge_events`: a history of badges earned\n\nEach rollup stores:\n- category (e.g., `blood_sugar`)\n- period start/end (YYYY-MM-DD)\n- streak, completion rate, XP\n- badges as JSON\n- summary stats as JSON\n\n## How new trackers fit in\n\nFor each new Notion database:\n1) Add a small “collector” val that maps entries into a shared event format.\n2) Reuse the rollup logic and write weekly results to SQLite.\n3) Generate emails or dashboards from the stored rollups.\n\nThis keeps the system simple while still scaling to many life areas.\n",[],[220],{"_105":228,"_96":229,"_154":230,"_156":-5,"_157":140,"_158":231,"_160":22,"_107":232,"_101":233,"_163":188,"_165":234,"_166":22,"_167":-5,"_168":235,"_99":236},"1ee4bf9c-f0cc-11f0-ba7d-42dde27851f2","README.md","904dec56-f0bf-11f0-a3c7-42dde27851f2",34,["D",1768341993069],7,"# Notion Blood Sugar Weekly Rollup (Val Town)\n\nThis repo contains a Val Town-ready script that:\n- queries a Notion database for the last 7 days of blood sugar entries (UTC date range)\n- computes simple stats (avg/min/max, count, missing entries, expected 2 per day)\n- emails a weekly rollup to your Val Town account (free tier friendly)\n\n## What this does (plain language)\n\nThink of this as a simple weekly helper:\n- You write down blood sugar readings in Notion.\n- Once a week, the script looks at the last 7 days of entries.\n- It adds up your numbers to give you a quick summary.\n- Then it emails that summary to you automatically.\n\n## A tiny bit of computer science (friendly version)\n\nEven though this feels simple, it uses a few classic CS ideas:\n- **Data modeling:** you define what a “reading” is (date, time, value).\n- **Filtering:** you only look at a specific window of time (last 7 days).\n- **Aggregation:** you summarize many values into a few stats (avg/min/max).\n- **Automation:** a scheduled job runs the same steps every week.\n\nIf you can build or understand this, you’re already practicing real CS thinking—just without the scary jargon.\n\n## Medical disclaimer\n\nThis report is for informational purposes only and is not medical advice.\nHealthy blood sugar ranges referenced here come from:\nhttps://www.ynhhs.org/articles/what-is-healthy-blood-sugar\n\n## 1) Create the Notion database\n\nCreate a new database in Notion (table view is easiest) with these properties:\n\n- **Entry** (Title)\n- **Created Time** (Created time) or **Created Time** (Text)\n- **Measurement Date** (Date) (e.g., `January 13, 2026`)\n- **Blood Sugar Level** (Number)\n- **Notes** (Text) (optional)\n\nYou can name the database anything (e.g., \"Blood Sugar Log\").\n\n## 2) Create a Notion integration\n\n1. Go to https://www.notion.so/my-integrations and create a new integration.\n2. Copy the **Internal Integration Token**.\n3. Open your database in Notion, click **Share**, and invite the integration.\n\n### Database ID\nOpen the database in the browser and copy the 32‑character ID in the URL.\n\n## 3) Configure Val Town\n\nCreate a new Val in Val Town and paste `notion_weekly_report.ts`.\n\nAdd these secrets in Val Town (Settings → Secrets):\n- `NOTION_TOKEN`\n- `NOTION_DATABASE_ID`\n- `REPORT_FROM_EMAIL` (optional, must be `your_username.valname@valtown.email`)\n- `REPORT_FROM_NAME` (optional)\n- `REPORT_REPLY_TO` (optional)\n \nFree tier note: this val emails the account owner by default.\n\n## 4) Schedule the report\n\nIn Val Town, schedule the Val to run weekly at 9:30am on Tuesdays (EST).\n\nSuggested cron (set Val Town timezone to EST):\n```\n30 9 * * 2\n```\n\n### What the cron line means\n\nCron is a simple way to say “run this on a schedule.” It has five fields:\n\n```\nminute hour day-of-month month day-of-week\n```\n\nSo `30 9 * * 2` means:\n- minute = 30\n- hour = 9\n- day-of-month = * (every day of the month)\n- month = * (every month)\n- day-of-week = 2 (Tuesday)\n\nIn other words: every Tuesday at 9:30am.\n\n## 5) Customize\n\n- Adjust the stats, date range, or email formatting in `notion_weekly_report.ts`.\n- If you prefer different property names, update them in the script.\n",[],[229],{"_105":238,"_96":239,"_154":240,"_156":-5,"_157":140,"_158":241,"_160":161,"_107":242,"_101":205,"_163":188,"_165":243,"_166":22,"_167":-5,"_168":244,"_99":245},"af5e30dc-f0ca-11f0-b515-42dde27851f2","deno.json","90417d36-f0bf-11f0-b9cf-42dde27851f2",32,["D",1768341376411],"{\n
