SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Decouple the object that invokes an operation from the object that performs it, enabling flexible command execution, undo/redo support, and easier maintenance.

Core Features & Use Cases

  • Decouples invocation from execution to simplify code changes and testing.
  • Supports queued or time-bound commands, unlocks undo/redo workflows, and enables pluggable behavior via command objects.
  • Common use cases include orchestrating domain operations, UI workflows, or any scenario needing pluggable command execution.

Quick Start

Create a Command class with an execute method and use an OrderManager.execute to run specific command objects.

FAQPage Schema
How do I implement undo and redo workflows in JavaScript applications?

Implement undo and redo workflows by wrapping actions in Command objects with execute methods and routing them through a central executor manager that tracks history for reversible operations.

What is the command pattern and when should I use it in TypeScript?

The command pattern decouples operations from their initiators by encapsulating actions in command objects. Use it in TypeScript when you need queuing, configurable lifespans, or pluggable execution interfaces.

How do I decouple UI actions from business logic execution in JavaScript?

Decouple UI actions from business logic by wrapping operations in concrete command classes and delegating execution to an OrderManager, allowing invokers to trigger commands without knowing execution details.

Can I queue or schedule time-bound operations using the command pattern?

Yes, the command pattern supports queued or time-bound commands by wrapping actions in command objects, enabling a central executor to manage delayed execution and orchestrate domain operations.

Does the command pattern require external dependencies to manage operations?

No, the command pattern requires no external dependencies. It relies on a pluggable execute interface, concrete command implementations, and a manager class built natively in JavaScript or TypeScript.
