We encourage you to make use of Jetstream wherever you may consider using the `com.atproto.sync.subscribeRepos` firehose if you don't need the features of the full sync protocol.\n\nBecause cursors for Jetstream are time-based (unix microseconds), you can use the same cursor for multiple instances to get roughly the same data.\n\nWhen switching between instances, it may be prudent to rewind your cursor a few seconds for gapless playback if you process events idempotently.\n\n## Running Jetstream\n\nTo run Jetstream, make sure you have docker and docker compose installed and run `make up` in the repo root.\n\nThis will pull the latest built image from GHCR and start a Jetstream instance at `http://localhost:6008`\n\n- To build Jetstream from source via Docker and start it up, run `make rebuild`\n\nOnce started, you can connect to the event stream at: `ws://localhost:6008/subscribe`\n\nPrometheus metrics are exposed at `http://localhost:6009/metrics`\n\nA [Grafana Dashboard](#dashboard-preview) for Jetstream is available at `./grafana-dashboard.json` and should be easy to copy/paste into Grafana's dashboard import prompt.\n\n- This dashboard has a few device-specific graphs for disk and network usage that require NodeExporter and may need to be tuned to your setup.\n\n## Consuming Jetstream\n\nTo consume Jetstream you can use any websocket client\n\nConnect to `ws://localhost:6008/subscribe` to start the stream\n\nThe following Query Parameters are supported:\n\n- `wantedCollections` - An array of [Collection NSIDs](https://atproto.com/specs/nsid) to filter which records you receive on your stream (default empty = all collections)\n - `wantedCollections` supports NSID path prefixes i.e. `app.bsky.graph.*`, or `app.bsky.*`. The prefix before the `.*` must pass NSID validation and Jetstream **does not** support incomplete prefixes i.e. `app.bsky.graph.fo*`.\n - Regardless of desired collections, all subscribers receive Account and Identity events.\n - You can specify at most 100 wanted collections/prefixes.\n- `wantedDids` - An array of Repo DIDs to filter which records you receive on your stream (Default empty = all repos)\n - You can specify at most 10,000 wanted DIDs.\n- `maxMessageSizeBytes` - The maximum size of a payload that this client would like to receive. Zero means no limit, negative values are treated as zero. (Default \"0\" or empty = no maximum size)\n- `cursor` - A unix microseconds timestamp cursor to begin playback from\n - An absent cursor or a cursor from the future will result in live-tail operation\n - When reconnecting, use the `time_us` from your most recently processed event and maybe provide a negative buffer (i.e. subtract a few seconds) to ensure gapless playback\n- `compress` - Set to `true` to enable `zstd` [compression](#compression)\n- `requireHello` - Set to `true` to pause replay/live-tail until the server receives a [`SubscriberOptionsUpdatePayload`](#options-updates) over the socket in a [Subscriber Sourced Message](#subscriber-sourced-messages)\n\n### Examples\n\nA simple example that hits the public instance looks like:\n\n```bash\n$ websocat wss://jetstream2.us-east.bsky.network/subscribe\\?wantedCollections=app.bsky.feed.post\n```\n\nA maximal example using all parameters looks like:\n\n```bash\n$ websocat \"ws://localhost:6008/subscribe?wantedCollections=app.bsky.feed.post&wantedCollections=app.bsky.feed.like&wantedCollections=app.bsky.graph.follow&wantedDids=did:plc:q6gjnaw2blty4crticxkmujt&cursor=1725519626134432\"\n```\n\n### Example events:\n\nJetstream events have 3 `kinds`s (so far):\n\n- `commit`: a Commit to a repo which involves either a create, update, or delete of a record\n- `identity`: an Identity update for a DID which indicates that you may want to purge an identity cache and revalidate the DID doc and handle\n- `account`: an Account event that indicates a change in account status i.e. from `active` to `deactivated`, or to `takendown` if the PDS has taken down the repo.\n\nJetstream Commits have 3 `operations`:\n\n- `create`: Create a new record with the contents provided\n- `update`: Update an existing record and replace it with the contents provided\n- `delete`: Delete an existing record with the DID, Collection, and RKey provided\n\n#### A like committed to a repo\n\n```json\n{\n \"did\": \"did:plc:eygmaihciaxprqvxpfvl6flk\",\n \"time_us\": 1725911162329308,\n \"kind\": \"commit\",\n \"commit\": {\n \"rev\": \"3l3qo2vutsw2b\",\n \"operation\": \"create\",\n \"collection\": \"app.bsky.feed.like\",\n \"rkey\": \"3l3qo2vuowo2b\",\n \"record\": {\n \"$type\": \"app.bsky.feed.like\",\n \"createdAt\": \"2024-09-09T19:46:02.102Z\",\n \"subject\": {\n \"cid\": \"bafyreidc6sydkkbchcyg62v77wbhzvb2mvytlmsychqgwf2xojjtirmzj4\",\n \"uri\": \"at://did:plc:wa7b35aakoll7hugkrjtf3xf/app.bsky.feed.post/3l3pte3p2e325\"\n }\n },\n \"cid\": \"bafyreidwaivazkwu67xztlmuobx35hs2lnfh3kolmgfmucldvhd3sgzcqi\"\n }\n}\n```\n\n#### A deleted follow record\n\n```json\n{\n \"did\": \"did:plc:rfov6bpyztcnedeyyzgfq42k\",\n \"time_us\": 1725516666833633,\n \"kind\": \"commit\",\n \"commit\": {\n \"rev\": \"3l3f6nzl3cv2s\",\n \"operation\": \"delete\",\n \"collection\": \"app.bsky.graph.follow\",\n \"rkey\": \"3l3dn7tku762u\"\n }\n}\n```\n\n#### An identity update\n\n```json\n{\n \"did\": \"did:plc:ufbl4k27gp6kzas5glhz7fim\",\n \"time_us\": 1725516665234703,\n \"kind\": \"identity\",\n \"identity\": {\n \"did\": \"did:plc:ufbl4k27gp6kzas5glhz7fim\",\n \"handle\": \"yohenrique.bsky.social\",\n \"seq\": 1409752997,\n \"time\": \"2024-09-05T06:11:04.870Z\"\n }\n}\n```\n\n#### An account becoming active\n\n```json\n{\n \"did\": \"did:plc:ufbl4k27gp6kzas5glhz7fim\",\n \"time_us\": 1725516665333808,\n \"kind\": \"account\",\n \"account\": {\n \"active\": true,\n \"did\": \"did:plc:ufbl4k27gp6kzas5glhz7fim\",\n \"seq\": 1409753013,\n \"time\": \"2024-09-05T06:11:04.870Z\"\n }\n}\n```\n\n### Compression\n\nJetstream supports `zstd`-based compression of messages. Jetstream uses a custom dictionary for compression that can be found in `pkg/models/zstd_dictionary` and is required to decode compressed messages from the server.\n\n`zstd` compressed Jetstream messages are ~56% smaller on average than the raw JSON version of the Jetstream firehose.\n\nThe provided client library uses compression by default, using an embedded copy of the Dictionary from the `models` package.\n\nTo request a compressed stream, pass the `Socket-Encoding: zstd` header through when initiating the websocket _or_ pass `compress=true` in the query string.\n\n### Subscriber Sourced messages\n\nSubscribers can send Text messages to Jetstream over the websocket using the `SubscriberSourcedMessage` framing below:\n\n```go\ntype SubscriberSourcedMessage struct {\n\tType string `json:\"type\"`\n\tPayload json.RawMessage `json:\"payload\"`\n}\n```\n\nThe supported message types are as follows:\n\n- `options_update`\n\n#### Options Updates\n\nA client can update their `wantedCollections` and `wantedDids` after connecting to the socket by sending a Subscriber Sourced Message.\n\nTo send an Options Update, provide the string `options_update` in the `type` field and a `SubscriberOptionsUpdatePayload` in the `payload` field.\n\nThe shape for a `SubscriberOptionsUpdatePayload` is as follows:\n\n```go\ntype SubscriberOptionsUpdateMsg struct {\n\tWantedCollections []string `json:\"wantedCollections\"`\n\tWantedDIDs []string `json:\"wantedDids\"`\n\tMaxMessageSizeBytes int `json:\"maxMessageSizeBytes\"`\n}\n```\n\nIf either array is empty, the relevant filter will be disabled (i.e. sending empty `wantedDids` will mean a client gets messages for all DIDs again).\n\nSome limitations apply around the size of the message: right now the message can be at most 10MB in size and can contain up to 100 collection filters _and_ up to 10,000 DID filters.\n\nAdditionally, a client can connect with `?requireHello=true` in the query params to pause replay/live-tail until the first Options Update message is sent by the client over the socket.\n\nInvalid Options Updates in `requireHello` mode or normal operating mode will result in the client being disconnected.\n\nAn example Subscriber Sourced Message with an Options Update payload is as follows:\n\n```json\n{\n \"type\": \"options_update\",\n \"payload\": {\n \"wantedCollections\": [\"app.bsky.feed.post\"],\n \"wantedDids\": [\"did:plc:q6gjnaw2blty4crticxkmujt\"],\n \"maxMessageSizeBytes\": 1000000\n }\n}\n```\n\nThe above payload will filter such that a client receives only posts, and only from a the specified DID.\n\n### Dashboard Preview\n\n![A screenshot of the Jetstream Grafana

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: \"

\"\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│ │ └──

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",[],[290],{"_103":298,"_95":299,"_152":300,"_154":-5,"_155":137,"_156":192,"_158":159,"_105":301,"_100":32,"_161":257,"_163":302,"_164":22,"_165":-5,"_166":303,"_98":304},"b3c85bfc-a3f4-11f0-87d5-0224a6c84d84","deno.json","b3c85cec-a3f4-11f0-87d5-0224a6c84d84",["D",1759893183199],"{\n
