SQLiteKV
SQLiteKV is a key-value store built on top of SQLite3. This project allows you to perform basic key-value operations with the additional power of SQLite3, making it suitable for applications requiring persistent, lightweight, and reliable storage.
Features
- Basic key-value operations: set, get, delete, exists, keys
- Support for expiry times on keys
- JSON export of the database
- Loop operations for repetitive tasks
- Transaction management
- Flexible journal modes (WAL, DELETE, etc.)
- In-memory, temporary, and disk-based storage options
- Logger mode to track executed SQL queries
Installation
You can install the package by running the following command with npm
:
npm install sqlitekv
Or with pnpm
:
pnpm install sqlitekv
Usage
Basic Setup
Here is an example of how to set up and use the SQLiteKV store:
import SQLiteKV from "sqlitekv";
(async () => {
try {
// Initialize the database with configuration
const db = new SQLiteKV("example.sqlite", {
tableName: "example_table",
autoCommit: true,
journalMode: "WAL",
enableLoopOperations: true,
logQueries: true
});
// Perform some operations
await db.set("key1", "value1");
const value = await db.get("key1");
console.log(`Retrieved value for key1: ${value}`);
// Check if a key exists
const exists = await db.exists("key1");
console.log(`Key1 exists: ${exists}`);
// Delete a key
await db.delete("key1");
console.log(`Key1 deleted`);
// Export the database to JSON
await db.convertToJson("export.json");
console.log("Database exported to export.json");
} catch (error) {
console.error("Error initializing database:", error);
}
})();
You can also initialize the database without passing the configuration object:
import SQLiteKV from "sqlitekv";
(async () => {
try {
// Initialize the database with default settings
const db = new SQLiteKV("example.sqlite");
// Perform some operations
await db.set("key1", "value1");
const value = await db.get("key1");
console.log(`Retrieved value for key1: ${value}`);
// Check if a key exists
const exists = await db.exists("key1");
console.log(`Key1 exists: ${exists}`);
// Delete a key
await db.delete("key1");
console.log(`Key1 deleted`);
// Export the database to JSON
await db.convertToJson("export.json");
console.log("Database exported to export.json");
} catch (error) {
console.error("Error initializing database:", error);
}
})();
Loop Operations
If you need to perform a set of operations repeatedly, you can use the loop operations feature:
const operations = async () => {
const timestamp = new Date().toISOString();
await db.set(`test_key_${timestamp}`, `test_value_${timestamp}`);
console.log(
`Set key: test_key_${timestamp} with value: test_value_${timestamp}`
);
};
const iterations = 10;
await db.performLoopOperations(operations, iterations);
Configuration Options
You can customize the behavior of SQLiteKV using the following configuration options:
tableName
: The name of the table used for storing key-value pairs.autoCommit
: Whether to automatically commit transactions.journalMode
: The journal mode for SQLite (e.g., WAL, DELETE).sqliteMode
: The storage mode for SQLite (disk, memory, temp).logQueries
: Whether to log executed SQL queries.enableLoopOperations
: Whether to enable loop operations.
Viewing the SQLite Database
You can view and interact with the SQLite database using an online viewer such as SQLite Viewer.
