Assert zero snapshot requests in server mode.

🌐 Web query:
postgres.js version 3.4 how are JavaScript array parameters serialized, and how do you pass a JSON value to a json parameter?
💡 Result:
In postgres.js (version 3.4 and other 3.x versions), parameter serialization is handled automatically by the library using tagged template literals, which process query parameters before they are sent to the PostgreSQL database [1][2]. JavaScript Array Serialization Postgres.js automatically infers types for generic values, including JavaScript arrays [1][2]. When you pass a standard JavaScript array into a tagged template, the driver handles the serialization to the PostgreSQL array format [3]. If you encounter issues with automatic inference or need to explicitly specify an array type, you can use the sql.array helper [4][5]. For example: await sqlINSERT INTO my_table (my_array_col) VALUES (${sql.array(['value1', 'value2'])}); Passing JSON Values To pass a JSON or JSONB value to a PostgreSQL parameter, you should avoid using JSON.stringify manually, as this will double-serialize the data, resulting in a JSON string stored inside your JSONB column rather than a structured JSON object [3][6]. Instead, use the sql.json helper [7][3]. This tells the driver to serialize the value as JSON once, ensuring it is correctly stored as a JSON/JSONB object in the database [3]: await sqlINSERT INTO my_table (my_json_col) VALUES (${sql.json({ foo: 'bar', num: 1 })}); Using sql.json is the recommended, safe way to ensure data is handled as a structured JSON object rather than a literal string [3].

site:github.com/porsager/postgres v3.4.8 src/types.js array json sql.json parameter serialization
💡 Result:
In the postgres.js library (porsager/postgres), version 3.4.8 introduced specific internal updates to type handling and definitions [1][2]. Regarding the specific components mentioned: src/types.js and Parameter Serialization: The library's core mechanism for parameter serialization leverages PostgreSQL's ParameterDescription protocol to infer data types directly from the database, which usually eliminates the need for manual JSON serialization [3][4]. The library internally maps JavaScript types to their corresponding PostgreSQL counterparts [5]. If specific JSON/JSONB behavior is required—such as when calling functions that do not perform implicit type casting—the sql.json() helper can be used to explicitly identify a value as JSON, ensuring the correct OID (Object Identifier) is used by the driver during transmission [6][7][5]. Array and JSON Handling: - Array Serialization: The library provides an array() method (and corresponding ArrayParameter interface) to explicitly define parameters as arrays, which is particularly useful when the library cannot automatically infer the precise type from the database context [8][2]. - JSON Serialization: While sql.json() is available, it is often unnecessary in standard queries because the library automatically stringifies JavaScript objects to JSON when the database expects a JSON/JSONB type [3][4]. Using sql.json() is primarily reserved for edge cases, such as bypassing incorrect type inference or when using JSON-specific operators/functions where the driver might otherwise misidentify the parameter type [9][6][5]. Version 3.4.8 Notes: Version 3.4.8 included updates to types/index.d.ts and internal connection logic [1][2]. It notably introduced a regression in TypeScript support for TransactionSql due to the use of Omit in its interface definition, which stripped essential call signatures required for tagged template literals [2][10]. This was subsequently identified by the community as a breaking change for transaction-based queries [10]. For detailed usage, refer to the following sources: [8] Library TypeScript definitions (types/index.d.ts). [2] Discussion on the 3.4.8 regression. [10] Issue report detailing the fix for TransactionSql signatures in 3.4.8. [3] Discussion on the role of sql.json in v3+.

Serialize the JSON payload before binding it to $1::json.
For these arrays of objects, postgres@3.4.8 infers type 0 and converts each parameter with '' + x. This produces a comma-separated string such as [object Object],[object Object], which PostgreSQL rejects as $1::json. The zones insert fails before importing rows, and the trips batches have the same issue.

Exclude input.borough from borough facet counts.
conditions(input, 'all', 'borough') skips only the grid filter with ID borough. It still applies input.borough. When a visitor selects a borough, boroughFacets contains only that borough, so the other options disappear from ColumnFilter.
Add a context that skips the top-level borough clause.

In `@src/components/dashboard/server/queries.ts` at line 106, Update the borough
facet query around conditions so it excludes the top-level input.borough filter
while retaining the intended grid-filter exclusion. Ensure boroughFacets are
computed across all borough options, even when input.borough is selected, before
they are passed to ColumnFilter.

🌐 Web query:
Firefox anchor download attribute requires element appended to document click
💡 Result:
In Firefox, calling the.click method on an element that is not present in the document's DOM has historically been a no-op [1][2][3][4]. While this behavior is not strictly required by the modern HTML specification [5][6], Firefox has long required the anchor element to be appended to the document (e.g., to document.body) for the.click event to successfully initiate a download when using the download attribute [1][3][4][7]. To ensure cross-browser compatibility when programmatically triggering downloads, the standard practice is to: 1. Create the element. 2. Set the href (e.g., to a Blob URL or data URL) and download attributes [3][8][7]. 3. Append the element to the document.body [3][4][7]. 4. Call.click on the element [3][4][7]. 5. Remove the element from the document [3][4][7]. Example: const link = document.createElement('a'); link.href = '...'; link.download = 'filename.ext'; document.body.appendChild(link); // Required for Firefox link.click; document.body.removeChild(link); // Cleanup

Attach the link before clicking it and defer object URL revocation.
When remote is false, the client export clicks a detached anchor and revokes its object URL immediately. Firefox may not start the download, and early revocation can invalidate it.
🐛 Proposed fix for the client-mode CSV download
const url = URL.createObjectURL(blob)
const link = document.createElement('a')
link.href = url
link.download = selection ? 'selected-trips.csv' : 'filtered-trips.csv'
+ document.body.append(link)
link.click()
- URL.revokeObjectURL(url)
+ link.remove()
+ setTimeout(() => URL.revokeObjectURL(url), 0)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

kind of a weird pattern for demo purposes?

/examples/dashboard, a public taxi-data dashboard backed by a dedicated Neon project and Cloudflare Hyperdrive. Shared immutable results and the full CSV use R2; filtering, sorting, grouping, pagination, and selected exports run on the server. A client mode and native, Material UI, and shadcn/Base UI skins share the same data contract.Includes the full-featured TanStack Table grid, Query loading and recovery behavior, shared chart motion defaults, a Redact ref-ordering fix for Material controls, and scripts and documentation for extracting the example.
Validation: production build, 524 passing tests with one skipped, and hosted preview regression coverage across all six component/data combinations. Verified the 8,936-row R2 CSV and persistent response cache. Neon uses separate compute fixed at 0.25 CU with five-minute autosuspend and a read-only runtime role.
