hGet() - Read Value

hGet(key: string, field: string)

First the JavaScript Map Object is read from the database. If the data record (marked with key) does not exist, undefined is returned. If the field (marked with field) does not exist in the "Map Object", undefined is returned.

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.

Inspired by: https://docs.keydb.dev/docs/commands/#hget

key

The key must be a string.

field

The field name must be a string.

Example

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

const store = new BunSqliteKeyValue()

store.hSet("key-1", "field-1", "value-1")

store.hGet("key-1", "field-1") // --> "value-1"
store.hGet("key-1", "field-2") // --> undefined
