All methods async.\n\n## Usage\n\n```javascript\nconst table = new SQLiteTable(\"myTable\", {\n id: \"unique primary key\",\n title: \"text\",\n body: \"text\",\n created: \"integer\",\n});\n\nawait table.create();\n```\n\n---\n\n# API\n\n## Basics\n\n#### `new SQLiteTable(name: string, schema: TableScheme, options?)`\n\nStart an instance of SQLiteTable. `schema` is a required object with column\nnames as keys and definitions as values — it is stored on the instance and used\nby `.create()`. See [TableScheme](#tablescheme) below for how to define columns.\n\n`options.scope` controls which SQLite database the table lives in:\n\n| Value | Database | Use when |\n| ------------------ | --------------------------- | --------------------------------------------------------------- |\n| `\"user\"` (default) | Shared across all your vals | Data should persist and be accessible from multiple vals |\n| `\"val\"` | Scoped to this val only | Data is private to this val, or you want isolation between vals |\n\n```javascript\n// User-scoped (default) — table is shared across your account\nconst table = new SQLiteTable(\"posts\", {\n id: \"unique primary key\",\n title: \"text\",\n});\n\n// Val-scoped — table is isolated to this val\nconst table = new SQLiteTable(\"posts\", { id: \"unique primary key\" }, {\n scope: \"val\",\n});\n```\n\n#### `.create()`\n\nCreate this table in your VT SQLite storage using the schema passed to the\nconstructor. Run this only once per table.\n\n#### `.drop()`\n\nDrop this table from your VT SQLite storage.\n\n#### `.exists()`\n\nReturns whether this table exists in storage.\n\n---\n\n## Write operations\n\n### `.insertRow(rowData)`\n\nAdd a new row to your table. `rowData` is a JSON with column names as keys, and\nrow values as values.\n\n```javascript\ntable.insertRow({\n id: 1234,\n title: \"Post title\",\n body: \"Post body\",\n created: 12345678,\n});\n```\n\n### `.deleteRows(conditions?)`\n\nDeletes all rows in the table that match the condition.\n\n### `.updateRow(conditions?, rowData)`\n\nModifies all rows in the table that match the condition. `rowData` is a JSON of\nkey-value pairs to change; it does not affect any columns not mentioned.\n\n```javascript\ntable.updateRow(\n { id: 1234 },\n {\n title:\n \"New title! The existing body text is not mentioned here so it is unaffected\",\n },\n);\n```\n\n---\n\n## Read operations\n\n### `.getInfo()`\n\nReturns metadata about the table:\n\n- `columns`: array of `{ name, type }` for each column\n- `rowCount`: total number of rows\n- `pageSize`, `pageCount`: SQLite page-level storage info\n- `estimatedTableBytes`, `humanReadableSize`: estimated table size on disk\n\n```javascript\nconst info = await table.getInfo();\n// {\n// columns: [{ name: \"id\", type: \"INTEGER\" }, { name: \"title\", type: \"TEXT\" }],\n// rowCount: 42,\n// humanReadableSize: \"4 KB\",\n// ...\n// }\n```\n\n### `.countRows(conditions?)`\n\nReturns a count of all rows in the table that match the condition.\n\nconditions: Either a JSON object of column conditions, or a raw SQL WHERE clause\nas a string. See [Conditions](#conditions) below.\n\n### `.getRow(conditions?, options?)`\n\nReturns the first row matching the given conditions.\n\n`options` is an optional [`SelectOutputOptionsBase`](#selectoutputoptionsbase) object.\n\n```javascript\ntable.getRow({ id: 1234 }, { json: true, columns: [\"id\", \"title\"] });\n```\n\n### `.getRows(conditions?, options?)`\n\nReturns all rows matching the given conditions.\n\n`options` is an optional [`SelectOutputOptions`](#selectoutputoptions) object, which extends `SelectOutputOptionsBase` with ordering.\n\n```javascript\n// Basic fetch\ntable.getRows({ status: \"active\" }, { json: true });\n\n// Sorted descending, limited\ntable.getRows({ status: \"active\" }, { json: true, descendBy: \"created\", limit: 10 });\n\n// Ascending, specific columns only\ntable.getRows(undefined, { json: true, ascendBy: \"score\", columns: [\"id\", \"score\"] });\n```\n\n---\n\n## Output options\n\n### `SelectOutputOptionsBase`\n\nShared options accepted by both `.getRow()` and `.getRows()`:\n\n| Field | Type | Default | Description |\n| --------- | ---------- | ------- | -------------------------------------------------------- |\n| `json` | `boolean` | `false` | Return plain JS objects instead of raw DB output |\n| `columns` | `string[]` | — | Limit which columns are returned (defaults to all) |\n\n### `SelectOutputOptions`\n\nExtends `SelectOutputOptionsBase` with ordering options, accepted by `.getRows()`. `ascendBy` and `descendBy` are mutually exclusive.\n\n| Field | Type | Default | Description |\n| ----------- | -------- | ------- | ---------------------------------------------- |\n| `ascendBy` | `string` | — | Column name to sort by, ascending (`ASC`) |\n| `descendBy` | `string` | — | Column name to sort by, descending (`DESC`) |\n| `limit` | `number` | — | Maximum number of rows to return |\n\n### `.streamRowBatches(onBatch: Function)`\n\nIterate over all rows in batches of 1000, passing each batch to onBatch.\n\n```javascript\nawait table.streamRowBatches((batch) => {\n for (const row of batch) {\n console.log(row);\n }\n});\n```\n\n---\n\n## Indices\n\n### `.getIndices()`\n\nReturns all indices on the table as an array of `{ name, sql }` objects.\n\n```javascript\nconst indices = await table.getIndices();\n// [{ name: \"idx_title\", sql: \"CREATE INDEX idx_title ON posts (title)\" }]\n```\n\n### `.addIndex({ name, column })`\n\nCreates an index on a single column. Note: there is no `IF NOT EXISTS` guard —\ncalling this twice with the same `name` will throw.\n\n```javascript\nawait table.addIndex({ name: \"idx_title\", column: \"title\" });\n```\n\n---\n\n## Web access\n\n### `.http(req: Request): Promise`\n\nExposes read operations (`getRow`, `getRows`, `countRows`, `getInfo`) as an HTTP\nhandler, so your table can be queried directly over the network. Useful for\nbuilding lightweight read APIs on top of your SQLite data without writing custom\nrouting logic.\n\nPass it as the handler in an HTTP val, bound to the table instance:\n\n```typescript\nimport { SQLiteTable } from \"https://esm.town/v/peterqliu/SQLiteTable/main.tsx\";\n\nconst table = new SQLiteTable(\"posts\", {\n id: \"unique primary key\",\n title: \"text\",\n});\n\nexport default (req: Request) => table.http(req);\n```\n\nThen query it via URL. The last path segment selects the operation, and query\nparams become row conditions:\n\n```\nGET /getRows?title=Hello\nGET /getRow?id=1234\nGET /countRows?created=12345678\n```\n\nUse `_columns` to limit which columns are returned:\n\n```\nGET /getRows?_columns=id,title\n```\n\n**Note:** Operators in object form are not available when using `.http()`. HTTP\nquery params only support simple equality conditions.\n\nUtilities\n\n### `.AISuggestCmd(plainText: string): Promise`\n\nUse AI to generate a suggested SQLite command for a given text description of\nyour intent.\n\n```javascript\nconst cmd = await table.AISuggestCmd(\n \"show me all active users sorted by join date\",\n);\n```\n\n---\n\n## TableScheme\n\nA `TableScheme` is a plain object where each key is a column name and each value\nis a column definition. Definitions can be provided in two forms:\n\n### String form\n\nPass a raw SQLite column definition string. The value is used verbatim, so you\nhave full control over type and constraints.\n\n```javascript\n{\n id: \"integer primary key\",\n title: \"text not null\",\n score: \"real default 0\",\n}\n```\n\n### Object form\n\nPass an object with the following optional fields:\n\n| Field | Type | Description |\n| ------------ | --------------------------------------------------- | ---------------------------------- |\n| `type` | `\"text\"` \\| `\"integer\"` \\| `\"number\"` \\| `\"string\"` | Column type (defaults to `\"text\"`) |\n| `primaryKey` | `boolean` | Adds `PRIMARY KEY` constraint |\n| `unique` | `boolean` | Adds `UNIQUE` constraint |\n\n```javascript\n{\n id: { type: \"integer\", primaryKey: true },\n email: { type: \"text\", unique: true },\n score: { type: \"number\" },\n bio: {}, // defaults to TEXT, no constraints\n}\n```\n\nBoth forms can be mixed freely in the same schema:\n\n```javascript\nconst table = new SQLiteTable(\"users\", {\n id: { type: \"integer\", primaryKey: true },\n email: { type: \"text\", unique: true },\n created: \"integer not null\",\n});\n```\n\n---\n\n## Conditions\n\nSome methods use a `conditions` argument to filter which rows are matched.\nConditions can be provided in two forms:\n\n### Object form (recommended)\n\nPass a plain JS object where each key is a column name. Multiple keys are joined\nwith `AND`.\n\n**Equality** (primitive value): matches rows where the column equals the value.\nA `null` value uses `IS NULL`.\n\n```javascript\ntable.getRows({ status: \"active\", score: 42 });\n// WHERE status = 'active' AND score = 42\n\ntable.getRows({ deleted_at: null });\n// WHERE deleted_at IS NULL\n```\n\n**Operator object**: for non-equality comparisons, set the value to an object\nwith one or more of the following operators. Multiple operators on the same key\nare also joined with `AND`.\n\n| Operator | SQL equivalent | Example |\n| ------------- | -------------- | ------------------------------------ |\n| `greaterThan` | `>` | `{ score: { greaterThan: 10 } }` |\n| `atLeast` | `>=` | `{ score: { atLeast: 10 } }` |\n| `lessThan` | `<` | `{ score: { lessThan: 100 } }` |\n| `atMost` | `<=` | `{ score: { atMost: 100 } }` |\n| `notEqual` | `!=` | `{ status: { notEqual: \"banned\" } }` |\n| `like` | `LIKE` | `{ title: { like: \"%hello%\" } }` |\n| `in` | `IN (...)` | `{ id: { in: [1, 2, 3] } }` |\n\n```javascript\n// Rows where score is between 10 and 100 (inclusive), and status is not \"banned\"\ntable.getRows({\n score: { atLeast: 10, atMost: 100 },\n status: { notEqual: \"banned\" },\n});\n\n// Rows where title contains \"hello\" (case-insensitive depends on collation)\ntable.getRows({ title: { like: \"%hello%\" } });\n\n// Rows where id is one of a set of values\ntable.getRows({ id: { in: [1, 2, 3] } });\n```\n\n### Raw SQL form\n\nPass a string to use a raw SQL `WHERE` clause directly. This gives you full\nSQLite expressiveness, but you are responsible for safe formatting.\n\n```javascript\ntable.getRows(\"created > 1700000000 OR pinned = 1\");\n```",[181],"173e166a-1752-11f1-b042-42dde27851f2","AGENTS.md","173e173c-1752-11f1-b042-42dde27851f2",424,["D",1772577676981],"You are an advanced assistant specialized in generating Val Town code.\n\n## Core Guidelines\n\n- Ask clarifying questions when requirements are ambiguous\n- Provide complete, functional solutions rather than skeleton implementations\n- Test your logic against edge cases before presenting the final solution\n- Ensure all code follows Val Town's specific platform requirements\n- If a section of code that you're working on is getting too complex, consider refactoring it into subcomponents\n\n## Code Standards\n\n- Generate code in TypeScript or TSX\n- Add appropriate TypeScript types and interfaces for all data structures\n- Prefer official SDKs or libraries than writing API calls directly\n- Ask the user to supply API or library documentation if you are at all unsure about it\n- **Never bake in secrets into the code** - always use environment variables\n- Include comments explaining complex logic (avoid commenting obvious operations)\n- Follow modern ES6+ conventions and functional programming practices if possible\n\n## Types of triggers\n\n### 1. 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

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

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",[189],"174b0a1e-1752-11f1-b042-42dde27851f2",".vtignore","174b0ac8-1752-11f1-b042-42dde27851f2",426,["D",1772577677068],".git\n.vscode\n.cursorrules\n.DS_Store\nnode_modules\nvendor",[196],"01db1fe6-1768-11f1-aed8-42dde27851f2","tests","01db20b8-1768-11f1-aed8-42dde27851f2",435,["D",1772587090024],"directory",[203],"pulls","branches","forks","envVars",{"_216":70,"_218":70},"connections",{"_216":70,"_217":70},"count","unfilledCount","emptyCount",{"_42":202,"_31":203,"_29":204,"_140":-5,"_40":41,"_39":205,"_142":48,"_37":276,"_13":70,"_33":207,"_35":-5,"_23":24,"_146":-5,"_232":277,"_26":278},{"_42":272,"_31":32,"_29":30,"_140":204,"_40":41,"_39":14,"_142":48,"_37":273,"_13":70,"_33":34,"_35":36,"_23":24,"_146":-5,"_232":274,"_26":275},{"_42":264,"_31":265,"_29":266,"_140":204,"_40":41,"_39":267,"_142":24,"_37":268,"_13":70,"_33":34,"_35":269,"_23":24,"_146":-5,"_232":270,"_26":271},{"_42":256,"_31":257,"_29":258,"_140":204,"_40":41,"_39":259,"_142":48,"_37":260,"_13":70,"_33":34,"_35":261,"_23":24,"_146":-5,"_232":262,"_26":263},{"_42":195,"_31":196,"_29":197,"_140":-5,"_40":41,"_39":198,"_142":48,"_37":253,"_13":70,"_33":20,"_35":200,"_23":24,"_146":-5,"_232":254,"_26":255},{"_42":188,"_31":189,"_29":190,"_140":-5,"_40":41,"_39":191,"_142":48,"_37":250,"_13":70,"_33":20,"_35":193,"_23":24,"_146":-5,"_232":251,"_26":252},{"_42":180,"_31":181,"_29":182,"_140":-5,"_40":41,"_39":183,"_142":24,"_37":247,"_13":185,"_33":20,"_35":186,"_23":24,"_146":-5,"_232":248,"_26":249},{"_42":173,"_31":174,"_29":175,"_140":-5,"_40":41,"_39":176,"_142":48,"_37":244,"_13":70,"_33":20,"_35":178,"_23":24,"_146":-5,"_232":245,"_26":246},{"_42":164,"_31":165,"_29":166,"_140":-5,"_40":41,"_39":167,"_142":48,"_37":241,"_13":169,"_33":170,"_35":171,"_23":24,"_146":-5,"_232":242,"_26":243},{"_42":156,"_31":157,"_29":158,"_140":-5,"_40":41,"_39":159,"_142":24,"_37":238,"_13":161,"_33":34,"_35":162,"_23":24,"_146":-5,"_232":239,"_26":240},{"_42":148,"_31":149,"_29":150,"_140":-5,"_40":41,"_39":151,"_142":24,"_37":235,"_13":153,"_33":34,"_35":154,"_23":24,"_146":-5,"_232":236,"_26":237},{"_42":137,"_31":138,"_29":139,"_140":-5,"_40":41,"_39":141,"_142":24,"_37":231,"_13":144,"_33":34,"_35":145,"_23":24,"_146":-5,"_232":233,"_26":234},["D",1772481061338],"children",[],[138],["D",1772586842947],[],[149],["D",1772586634026],[],[157],["D",1771726668666],[],[165],["D",1772577677006],[],[174],["D",1772479764165],[],[181],["D",1772577676981],[],[189],["D",1772577677068],[],[196],"01fac97c-1768-11f1-aed8-42dde27851f2","helpers.ts","01faca1c-1768-11f1-aed8-42dde27851f2",436,["D",1772587090234],"//
