Requirements
VS Code version 1.60.0 or higher
GitHub Copilot extension (recommended) OR
An API key from OpenAI or any OpenAI-compatible provider for fallback
Setup
Install the extension from the VS Code marketplace
Primary Setup (Recommended):
Install GitHub Copilot extension
Sign in to GitHub Copilot
The extension will automatically use Copilot for error explanations
Fallback Setup (Optional):
Open the command palette (Cmd/Ctrl + Shift + P)
Search for "TypeScript Error Wand: Set OpenAI Compatible API Key"
Enter your API key when prompted
(Optional) Set a custom base URL if using an alternative provider
Extension Settings
This extension contributes the following settings:
typescriptErrorWand.preferCopilot: Toggle whether to prefer GitHub Copilot over custom AI providers (default: true)
typescriptErrorWand.openai.model: The fallback AI model to use when Copilot is unavailable
typescriptErrorWand.openai.baseUrl: Custom API base URL for fallback provider
How It Works
When you hover over a TypeScript error in your code, the extension captures the error message and code
If GitHub Copilot is available, it uses Copilot's API to generate explanations
If Copilot isn't available, it falls back to the configured custom AI provider
The response is displayed in a hover card with:
A clear explanation of what caused the error
Step-by-step suggestions on how to fix it
Privacy & Security
Your code is never stored or logged
Uses GitHub Copilot's secure authentication when available
Fallback API calls use your personal API key
All processing happens on your machine and the respective AI provider's servers
