Class: TempDB

A temporary superfast in-memory key-value store with automatic invalidation.

Constructor

new TempDB(lifeTime: number, invalidationTime: number = 1)

Creates an instance of TempDB.

• Parameters:

  • lifeTime (number): The lifetime of each entry in minutes.

  • invalidationTime (number, optional): The interval for invalidation checks in minutes. Defaults to 1.

Methods

set(key: string, value: any): void

Sets a key-value pair in the TempDB with the current timestamp.

• Parameters:

  • key (string): The key for the entry.

  • value (any): The value to be stored.

get(key: string): { data: any; time: number } | undefined

Retrieves a value from the TempDB by key.

• Parameters:

  • key (string): The key for the entry to retrieve.

• Returns:

  • { data: any; time: number } | undefined: The value associated with the key, or undefined if not found.

Usage Example

import TempDB from "@riasat/tempdb";

// Create a TempDB instance with a lifetime of 1 minute for each entry
const db = new TempDB(1);

// Set a key-value pair in the database
db.set("riasatsk", 1256);

// Retrieve the value by key
console.log(db.get("riasatsk")); // Output: { data: 1256, time: 1628159995000 }

// Periodically log the entire database to the console
setInterval(() => {
  console.log(db);
}, 5000);

Notes

• The set method associates a value with a key and records the current timestamp.

• The get method retrieves the value and timestamp for a given key.

• Entries in the database are automatically invalidated and removed based on the specified lifeTime.
