Overview
This quick tip demonstrates how to automatically generate TypeScript type interfaces from JavaScript objects using GitHub Copilot Chat.
Requirements
To implement this tip, you’ll need:
- Visual Studio Code Insider’s build
- GitHub Copilot Chat
- Copilot Nightly
Workflow
- Copy an object received from a fetch request
- Open Copilot Chat
- Ask: “Generate a TypeScript interface for this object”
- Copilot generates the corresponding interface
Note: Sometimes the chat interface may display a filtered response message, yet the actual generated code will be correct when pasted into the editor.
Benefits
This technique streamlines TypeScript development by automating interface generation, saving you time when working with API responses.
If you copy the response and paste it in your editor, you’ll notice it’s correct—even when the chat indicates content filtering.
Takeaway
This tip is especially valuable for developers frequently handling external data sources who need rapid type definitions without manual coding.
