Type Alias: BlobInput¶

type BlobInput:
  | BlobData
  | BlobUri
  | object
  | object
  | object
  | null
  | undefined;

A value accepted for a lance.blob.v2 column (see blob).

Either inline bytes, a URI pointing at external bytes, or a struct that sets exactly one of data or uri. null and undefined write a null blob. External byte ranges require both position (non-negative) and size (positive). Use safe integer numbers or bigint values for these unsigned 64-bit byte counts.

Example¶

import { pathToFileURL } from "node:url";
import type { BlobInput } from "@lancedb/lancedb";

const rows: { id: bigint; image: BlobInput }[] = [
  { id: 1n, image: await (await fetch(url)).arrayBuffer() },
  { id: 2n, image: pathToFileURL("/data/cat.png") },
  { id: 3n, image: { data: new Blob(["hello"]) } },
];
await table.add(rows);
