HTTP Trigger\n\n- Create web APIs and endpoints\n- Handle HTTP requests and responses\n- Example structure:\n\n```ts\nexport default async function (req: Request) {\n return new Response(\"Hello World\");\n}\n```\n\nFiles that are HTTP triggers have http in their name like `foobar.http.tsx`\n\n### 2. Cron Triggers\n\n- Run on a schedule\n- Use cron expressions for timing\n- Example structure:\n\n```ts\nexport default async function () {\n // Scheduled task code\n}\n```\n\nFiles that are Cron triggers have cron in their name like `foobar.cron.tsx`\n\n### 3. Email Triggers\n\n- Process incoming emails\n- Handle email-based workflows\n- Example structure:\n\n```ts\nexport default async function (email: Email) {\n // Process email\n}\n```\n\nFiles that are Email triggers have email in their name like `foobar.email.tsx`\n\n\n## Val Town Standard Libraries\n\nVal Town provides several hosted services and utility functions.\n\n### Blob Storage\n\n```ts\nimport { blob } from \"https://esm.town/v/std/blob\";\nawait blob.setJSON(\"myKey\", { hello: \"world\" });\nlet blobDemo = await blob.getJSON(\"myKey\");\nlet appKeys = await blob.list(\"app_\");\nawait blob.delete(\"myKey\");\n```\n\n### SQLite\n\n```ts\nimport { sqlite } from \"https://esm.town/v/stevekrouse/sqlite\";\nconst TABLE_NAME = 'todo_app_users_2';\n// Create table - do this before usage and change table name when modifying schema\nawait sqlite.execute(`CREATE TABLE IF NOT EXISTS ${TABLE_NAME} (\n id INTEGER PRIMARY KEY AUTOINCREMENT,\n name TEXT NOT NULL\n)`);\n// Query data\nconst result = await sqlite.execute(`SELECT * FROM ${TABLE_NAME} WHERE id = ?`, [1]);\n```\n\nNote: When changing a SQLite table's schema, change the table's name (e.g., add _2 or _3) to create a fresh table.\n\n### OpenAI\n\n```ts\nimport { OpenAI } from \"https://esm.town/v/std/openai\";\nconst openai = new OpenAI();\nconst completion = await openai.chat.completions.create({\n messages: [\n { role: \"user\", content: \"Say hello in a creative way\" },\n ],\n model: \"gpt-4o-mini\",\n max_tokens: 30,\n});\n```\n\n### Email\n\n```ts\nimport { email } from \"https://esm.town/v/std/email\";\n// By default emails the owner of the val\nawait email({ \n subject: \"Hi\", \n text: \"Hi\", \n html: \"

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

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",[153],"96496a08-c320-11f0-b0c3-42dde27851f2",".vtignore","96496b3e-c320-11f0-b0c3-42dde27851f2",218,["D",1763320517603],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[160],"03ede404-c32a-11f0-85c1-42dde27851f2","obplot-dataviz","03ede59e-c32a-11f0-85c1-42dde27851f2",236,["D",1763324567036],"directory",[167],"5dc3b6a8-bd9d-11f0-9644-42dde27851f2","clearspace_screen_time","58c75844-bd9d-11f0-87c0-42dde27851f2",21,["D",1762714402899],1,[174],"5a290edc-bda5-11f0-a35b-42dde27851f2","bay-wheels","56d69024-bda5-11f0-be1c-42dde27851f2",25,["D",1762717832823],[181],"pulls","branches",2,"forks","envVars",{"_194":196,"_197":60},"connections",{"_194":60,"_195":60},"count","unfilledCount",5,"emptyCount",{"_42":180,"_31":181,"_29":182,"_136":-5,"_40":41,"_39":183,"_138":56,"_37":429,"_13":178,"_33":171,"_35":-5,"_23":24,"_141":-5,"_229":430,"_26":431},{"_42":420,"_31":421,"_29":422,"_136":182,"_40":41,"_39":423,"_138":24,"_37":424,"_13":425,"_33":317,"_35":426,"_23":24,"_141":-5,"_229":427,"_26":428},{"_42":412,"_31":413,"_29":414,"_136":182,"_40":41,"_39":415,"_138":24,"_37":416,"_13":176,"_33":34,"_35":417,"_23":24,"_141":-5,"_229":418,"_26":419},{"_42":403,"_31":404,"_29":405,"_136":182,"_40":41,"_39":406,"_138":24,"_37":407,"_13":408,"_33":34,"_35":409,"_23":24,"_141":-5,"_229":410,"_26":411},{"_42":395,"_31":396,"_29":397,"_136":182,"_40":41,"_39":398,"_138":24,"_37":399,"_13":351,"_33":317,"_35":400,"_23":24,"_141":-5,"_229":401,"_26":402},{"_42":387,"_31":388,"_29":389,"_136":182,"_40":41,"_39":390,"_138":56,"_37":391,"_13":188,"_33":34,"_35":392,"_23":24,"_141":-5,"_229":393,"_26":394},{"_42":173,"_31":174,"_29":175,"_136":-5,"_40":41,"_39":176,"_138":56,"_37":384,"_13":178,"_33":171,"_35":-5,"_23":24,"_141":-5,"_229":385,"_26":386},{"_42":376,"_31":377,"_29":378,"_136":175,"_40":41,"_39":379,"_138":24,"_37":380,"_13":178,"_33":20,"_35":381,"_23":24,"_141":-5,"_229":382,"_26":383},{"_42":372,"_31":32,"_29":30,"_136":175,"_40":41,"_39":14,"_138":24,"_37":373,"_13":60,"_33":34,"_35":36,"_23":24,"_141":-5,"_229":374,"_26":375},{"_42":364,"_31":365,"_29":366,"_136":175,"_40":41,"_39":367,"_138":56,"_37":368,"_13":178,"_33":148,"_35":369,"_23":24,"_141":-5,"_229":370,"_26":371},{"_42":355,"_31":356,"_29":357,"_136":175,"_40":41,"_39":358,"_138":24,"_37":359,"_13":360,"_33":148,"_35":361,"_23":24,"_141":-5,"_229":362,"_26":363},{"_42":346,"_31":347,"_29":348,"_136":175,"_40":41,"_39":349,"_138":24,"_37":350,"_13":351,"_33":148,"_35":352,"_23":24,"_141":-5,"_229":353,"_26":354},{"_42":338,"_31":339,"_29":340,"_136":175,"_40":41,"_39":341,"_138":56,"_37":342,"_13":60,"_33":34,"_35":343,"_23":24,"_141":-5,"_229":344,"_26":345},{"_42":330,"_31":331,"_29":332,"_136":175,"_40":41,"_39":333,"_138":56,"_37":334,"_13":178,"_33":148,"_35":335,"_23":24,"_141":-5,"_229":336,"_26":337},{"_42":321,"_31":322,"_29":323,"_136":175,"_40":41,"_39":324,"_138":24,"_37":325,"_13":326,"_33":148,"_35":327,"_23":24,"_141":-5,"_229":328,"_26":329},{"_42":311,"_31":312,"_29":313,"_136":175,"_40":41,"_39":314,"_138":56,"_37":315,"_13":316,"_33":317,"_35":318,"_23":24,"_141":-5,"_229":319,"_26":320},{"_42":302,"_31":303,"_29":304,"_136":175,"_40":41,"_39":305,"_138":56,"_37":306,"_13":307,"_33":34,"_35":308,"_23":24,"_141":-5,"_229":309,"_26":310},{"_42":293,"_31":294,"_29":295,"_136":175,"_40":41,"_39":296,"_138":56,"_37":297,"_13":298,"_33":34,"_35":299,"_23":24,"_141":-5,"_229":300,"_26":301},{"_42":285,"_31":286,"_29":287,"_136":175,"_40":41,"_39":288,"_138":56,"_37":289,"_13":178,"_33":148,"_35":290,"_23":24,"_141":-5,"_229":291,"_26":292},{"_42":166,"_31":167,"_29":168,"_136":-5,"_40":41,"_39":169,"_138":24,"_37":282,"_13":60,"_33":171,"_35":-5,"_23":24,"_141":-5,"_229":283,"_26":284},{"_42":277,"_31":250,"_29":244,"_136":168,"_40":41,"_39":278,"_138":24,"_37":279,"_13":60,"_33":171,"_35":-5,"_23":24,"_141":-5,"_229":280,"_26":281},{"_42":271,"_31":160,"_29":272,"_136":244,"_40":41,"_39":273,"_138":24,"_37":274,"_13":188,"_33":20,"_35":164,"_23":24,"_141":-5,"_229":275,"_26":276},{"_42":265,"_31":153,"_29":266,"_136":244,"_40":41,"_39":267,"_138":24,"_37":268,"_13":188,"_33":20,"_35":157,"_23":24,"_141":-5,"_229":269,"_26":270},{"_42":259,"_31":134,"_29":260,"_136":244,"_40":41,"_39":261,"_138":24,"_37":262,"_13":60,"_33":20,"_35":140,"_23":24,"_141":-5,"_229":263,"_26":264},{"_42":251,"_31":252,"_29":253,"_136":244,"_40":41,"_39":254,"_138":24,"_37":255,"_13":60,"_33":148,"_35":256,"_23":24,"_141":-5,"_229":257,"_26":258},{"_42":241,"_31":242,"_29":243,"_136":244,"_40":41,"_39":245,"_138":24,"_37":246,"_13":60,"_33":34,"_35":247,"_23":24,"_141":-5,"_229":248,"_26":249},{"_42":159,"_31":160,"_29":161,"_136":-5,"_40":41,"_39":162,"_138":56,"_37":238,"_13":60,"_33":20,"_35":164,"_23":24,"_141":-5,"_229":239,"_26":240},{"_42":152,"_31":153,"_29":154,"_136":-5,"_40":41,"_39":155,"_138":56,"_37":235,"_13":60,"_33":20,"_35":157,"_23":24,"_141":-5,"_229":236,"_26":237},{"_42":143,"_31":144,"_29":124,"_136":-5,"_40":41,"_

Most people sleep about seven or eight hours a night. That leaves 16 or 17 hours awake each day. Or about 1,000 minutes.

Let’s think about those 1,000 minutes as 100 10-minute blocks. That’s what you wake up with every day.

Throughout the day, you spend 10 minutes of your life on each block, until you eventually run out of blocks and it’s time to go to sleep.

It’s always good to step back and think about how we’re using those 100 blocks we get each day:

How many of them are put towards making your future better, and how many of them are just there to be enjoyed?
How many of them are spent with other people, and how many are for time by yourself?
How many are used to create something, and how many are used to consume something?
How many of the blocks are focused on your body, how many on your mind, and how many on neither one in particular?
Which are your favorite blocks of the day, and which are your least favorite?

Scenario:

At 8:30 AM, the cron job reports 100 minutes of screen time, but the previous reading at 8:20 AM was 0 minutes. This means 100 minutes of usage appeared in a 10-minute window - an overflow situation.

Solution: Instead of clamping to 10 minutes and losing 90 minutes, we backfill the previous empty blocks (7:00-8:20 AM) to distribute the usage.

This occurred when the cron job (running every 10 minutes) reported screen time increases greater than 10 minutes in a single interval.\n\n### Example Scenario\n- Record at 9:55 AM: 0 minutes\n- Record at 10:00 AM: 100 minutes\n- **Problem**: 100 minutes appeared in a 5-minute gap\n- **Old behavior**: Clamp to 10 minutes, lose 90 minutes to \"Artifacts\"\n- **New behavior**: Distribute 100 minutes backwards into empty blocks\n\n## Solution: Backfill Algorithm\n\n### Algorithm Steps\n\n1. **Iterate through time blocks sequentially** (7:00 AM - 11:40 PM, 100 blocks of 10 minutes each)\n\n2. **Calculate raw usage** for each block based on cumulative screen time data\n\n3. **Handle overflow**:\n - If usage ≤ 10 minutes: Use actual usage\n - If usage > 10 minutes: \n - Fill current block with 10 minutes\n - Add remainder to backlog\n\n4. **Backfill process**:\n - When backlog exists, work backwards from current block\n - Fill previous empty blocks until backlog is exhausted\n - Each block can hold maximum 10 minutes\n\n5. **Volume grid synchronization**:\n - Volume grid now uses timeline's active block count instead of simple `totalMinutes/10`\n - This ensures both grids always match in number of filled blocks\n\n### Implementation Details\n\n```typescript\n// Three-pass algorithm:\n// 1. Calculate raw usage for each block\n// 2. Apply backfill algorithm with backlog management\n// 3. Generate HTML and calculate statistics\n\n// Volume grid now syncs with timeline:\nconst actualActiveBlocks = timelineStats?.visibleBlocksCount || numFilled;\n```\n\n### Key Features\n\n- **Volume Preservation**: All screen time minutes are represented in the grid\n- **Timeline Approximation**: Usage is distributed backwards from sync points\n- **Visual Clarity**: No single \"exploded\" blocks with impossible usage\n- **Grid Synchronization**: Volume and timeline grids always show same number of active blocks\n- **Enhanced Tooltips**: Show backfilled vs. direct usage\n- **Statistics Tracking**: New \"Backfilled\" metric in blue\n\n## Results\n\n### Before (Clamping)\n- ❌ Lost minutes to \"Artifacts/Bursts\"\n- ❌ Timeline grid didn't match volume grid\n- ❌ Poor visual representation of actual usage\n- ❌ Volume showed 38 blocks, timeline showed 41 blocks\n\n### After (Backfill)\n- ✅ **Volume**: Total red blocks match total screen time\n- ✅ **Timeline**: Better approximation of when usage occurred\n- ✅ **Synchronization**: Both grids show identical number of active blocks\n- ✅ **Statistics**: Clear breakdown of backfilled vs. direct usage\n- ✅ **Tooltips**: Enhanced information about block contents\n\n## The Mismatch Issue & Fix\n\n### Why the Mismatch Occurred\nThe original volume grid used simple math: `Math.ceil(totalMinutes / 10)` to determine filled blocks. However, the backfill algorithm can create **more active blocks** than this simple calculation suggests.\n\n**Example**: \n- 380 minutes ÷ 10 = 38 blocks (volume grid)\n- But with overflow backfill: 41 blocks become active (timeline grid)\n- **Reason**: Overflow gets distributed backwards, activating additional blocks\n\n### The Fix\nThe volume grid now uses the timeline's actual active block count:\n```typescript\nconst actualActiveBlocks = timelineStats?.visibleBlocksCount || numFilled;\n```\n\nThis ensures **perfect synchronization** between both grids.\n\n## Files Modified\n\n- `clearspace-100-blocks.ts`: Main implementation with backfill algorithm and grid synchronization\n- `backfill-demo.ts`: Demonstration endpoint showing algorithm in action\n- `debug-mismatch.ts`: Debug tool for investigating volume/timeline discrepancies\n\n## Statistics Added\n\n- **Backfilled**: Minutes distributed backwards (shown in blue)\n- **Artifacts/Bursts**: Only unresolved overflow (should be minimal now)\n\n## Demo\n\nVisit `/clearspace_screen_time/backfill-demo.ts` to see a step-by-step demonstration of the algorithm with sample overflow data.",[],[174,377],["D",1762714402899],[205,206,207,208,209,210,211,212,213,214,215,216],[174],"476ff6b0-c274-11f0-9f81-42dde27851f2","snooze-utils.ts","d2509ef2-c273-11f0-9bd8-42dde27851f2",160,["D",1763246511892],"import { blob } from \"https://esm.town/v/std/blob\";\n\nconst SNOOZE_KEY = \"snoozed_today\";\n\nexport async function getSnoozedToday(): Promise {\n try {\n const snoozed = await blob.getJSON(SNOOZE_KEY);\n return snoozed === true;\n } catch (error) {\n // If key doesn't exist, default to false\n return false;\n }\n}\n\nexport async function setSnoozedToday(snoozed: boolean): Promise {\n await blob.setJSON(SNOOZE_KEY, snoozed);\n}\n\n/**\n * Helper function to check if emails should be sent today.\n * Returns true if emails should be sent, false if they're snoozed.\n */\nexport async function shouldSendEmails(): Promise {\n const snoozed = await getSnoozedToday();\n return !snoozed;\n}",[],[181,388],"10506c62-c28f-11f0-96c7-42dde27851f2","reset-snooze-cron.ts","e4b40e9e-c273-11f0-9fc4-42dde27851f2",214,["D",1763258015818],"// NOTE: val town defaults to UTC time, which is why this cron is scheduled for 9am (that's 1am in PT)\n\nimport { setSnoozedToday } from \"./snooze-utils.ts\";\n\nexport default async function () {\n try {\n // Reset snooze status to false at midnight PT\n await setSnoozedToday(false);\n console.log(\n `[${new Date().toISOString()}] Successfully reset snooze status to false`,\n );\n } catch (error) {\n console.error(\n `[${new Date().toISOString()}] Failed to reset snooze status:`,\n error,\n );\n throw error;\n }\n}",[],[181,396],"15fafa8c-c277-11f0-962f-42dde27851f2","panhandle-stations-data.ts","f3860cbc-bda8-11f0-b0ec-42dde27851f2",197,["D",1763247717402],27,"import getBayWheelsData from \"./bay-wheels-data.ts\";\n\n/**\n * Filters the merged GBFS station data for specific stations.\n * @param {Array} mergedData - Array of station objects (merged info + status).\n * @returns {Array} Filtered station data.\n */\nexport default async function getPanhandleStationsData() {\n // Define the target stations\n const TARGET_STATIONS = [\n { name: \"Broderick at Oak\", short_name: \"SF-K18\" },\n { name: \"Grove at Divisadero\", short_name: \"SF-J18\" },\n { name: \"Page at Scott\", short_name: \"SF-K19\" },\n { name: \"Pierce at Haight\", short_name: \"SF-K20\" },\n ];\n\n const mergedData = await getBayWheelsData();\n\n const panhandleData = mergedData.filter((station) =>\n TARGET_STATIONS.some((target) =>\n station.short_name === target.short_name ||\n (station.name && station.name.toLowerCase() === target.name.toLowerCase())\n )\n );\n console.log(panhandleData);\n\n return panhandleData;\n}",[],[181,404],"9650d8b0-c320-11f0-a641-42dde27851f2","bay-wheels-data.ts","5e1f5898-bda5-11f0-ade4-42dde27851f2",219,["D",1763320517650],"export default async function getBayWheelsData() {\n // Bay Wheels GBFS feed URLs\n const STATION_INFO_URL =\n \"https://gbfs.baywheels.com/gbfs/2.3/en/station_information.json\";\n const STATION_STATUS_URL =\n \"https://gbfs.baywheels.com/gbfs/2.3/en/station_status.json\";\n\n // Fetch both feeds concurrently\n const [infoRes, statusRes] = await Promise.all([\n fetch(STATION_INFO_URL),\n fetch(STATION_STATUS_URL),\n ]);\n\n const infoJson = await infoRes.json();\n const statusJson = await statusRes.json();\n\n type StationInfo = {\n name: string;\n short_name: string | null;\n address: string | null;\n capacity: number | null;\n };\n\n // Build a map of static station info keyed by station_id\n const infoMap = new Map(\n infoJson.data.stations.map((s: any) => [\n s.station_id,\n {\n name: s.name,\n short_name: s.short_name ??
