Copilot Tips: Sync/Async

Overview

This article provides guidance on using GitHub Copilot Chat to efficiently refactor TypeScript function signatures between synchronous and asynchronous patterns.

Requirements

• Visual Studio Code 1.80.1 or newer
• GitHub Copilot extension
• Copilot Chat extension installed

The Technique

The process involves three straightforward steps:

1. Highlight the code block containing the function
2. Press cmd + i to launch the inline chat interface
3. Request that Copilot convert the function between async and sync formats

Bidirectional Capability

The approach works in both directions—you can transform asynchronous functions into synchronous ones, or vice versa, making it adaptable to various refactoring scenarios.

Example

To make async:

Hit cmd + i and ask: "Make this function async"

To make sync:

Hit cmd + i and ask: "Make this function synchronous"

Target Audience

This tip specifically addresses TypeScript developers seeking efficient ways to manage function signature updates within their development workflow.
