hGetCount() - Count Fields

hGetCount(key: string)

Returns the number of fields contained in the hash stored at key.

Do not use the hash functions with several very large amounts (megabytes) of data or blobs. This is because the entire data record with all fields is always read and written. It is better to use setValues() and getValues() for large amounts of data.

key

The key must be a string.

Example

import { BunSqliteKeyValue } from "bun-sqlite-key-value"

const store = new BunSqliteKeyValue()

store.hGetCount("key-1") // --> undefined
store.hSet("key-1", "field-1", "value-1")
store.hGetCount("key-1") // --> 1
