# command-pattern-queue [![npm version](https://badge.fury.io/js/command-pattern-queue.svg)](https://badge.fury.io/js/command-pattern-queue)

### Basic implementation of command-pattern queue

## Usage:

```

npm i command-pattern-queue

```

```typescript

// command interface

export interface ICommand {

    execute(): void

    unexecute(): void

}

const commandQueue = new CommandQueue(); // create queue

// execute ICommand-s

await commandQueue.executeCommand(Command1);

await commandQueue.executeCommand(Command2);

await commandQueue.executeCommands([Command3, Command4, Command5, Command6]);

// undo command

await commandQueue.undoCommand() // undo 1 command

await commandQueue.undoCommand(3) // undo 3 command

// redo commands

await commandQueue.redoCommand(); // redo 1 command

await commandQueue.redoCommand(2); // redo 2 command

```
