Bun KVStore

KVStore is a simple key-value store implementation using bun SQLite, designed for easy storage and retrieval of data in a structured format.

To install the KVStore package, you can use npm or yarn. Run the following command in your project directory:

bun install bun-kvstore

First, import the KVStore class into your project:

import { KVStore } from 'bun-kvstore';

Create an instance of the KVStore by providing a database name: If empty, the database will be created in the memory.

const store = new KVStore('my-database.db');

You can set a key-value pair using the set method:

await store.set('myKey', { name: 'John Doe', age: 30 });

To retrieve a value by its key, use the get method:

const value = await store.get('myKey');
console.log(value); // Output: { name: 'John Doe', age: 30 }

To delete a key-value pair, use the delete method:

await store.delete('myKey');

You can list all key-value pairs stored in the database:

const allEntries = await store.list();
console.log(allEntries); // Output: [{ key: 'myKey', value: { name: 'John Doe', age: 30 } }, ...]

To clear all entries in the store, use the clear method:

await store.clear();

You can set multiple key-value pairs at once using batchSet:

await store.batchSet([
  { key: 'key1', value: 'value1' },
  { key: 'key2', value: { data: 'value2' } },
]);

And delete multiple keys using batchDelete:

await store.batchDelete(['key1', 'key2']);

constructor(dbName: string): Initializes a new instance of the KVStore with the specified database name.

set(key: string, value: KVStoreValue): Promise<void>: Sets a key-value pair in the store.
get(key: string): Promise<KVStoreValue | null>: Retrieves the value associated with the specified key.
delete(key: string): Promise<void>: Deletes the key-value pair associated with the specified key.
list(): Promise<{ key: string; value: KVStoreValue }[]>: Returns an array of all key-value pairs in the store.
clear(): Promise<void>: Clears all key-value pairs from the store.
batchSet(entries: { key: string; value: KVStoreValue }[]): Promise<void>: Sets multiple key-value pairs in the store.
batchDelete(keys: string[]): Promise<void>: Deletes multiple key-value pairs from the store.
