💡 Zod Type Infer-er

A VSCode extension that automatically generates TypeScript types using z.infer from your Zod schema definitions — right from a lightbulb Quick Fix 💡.

✨ Features

• 🔍 Detects z.object({ ... }) schema definitions
• 🧠 Suggests and inserts:

  export type MyType = z.infer<typeof mySchema>;
  

• 🛠 Offers two options:

  • export type
  • non-exported type

• 🔄 Updates existing type aliases if they already exist

⚡ Example

When you write:

const recordSaleRequestSchema = z.object({
  barcode: z.string(),
});

Hover over the line or click the 💡 lightbulb — and choose:

💡 Generate exported type: RecordSaleRequest
💡 Generate internal type: RecordSaleRequest

The extension will insert (or update):

export type RecordSaleRequest = z.infer<typeof recordSaleRequestSchema>;
