ts-auto-types for VS Code

Generate TypeScript types from JSON without leaving the editor.

A VS Code extension for ts-auto-types, the smart TypeScript type generator. Select JSON, generate types in seconds — no configuration required.

Features

✨ Smart Type Generation — Automatically detects optional fields, nullable unions, string-literal unions, and more.

🔧 No Configuration by Default — Works perfectly on real-world JSON without setup.

🎯 Fast and Local — Instant results, your data never leaves your machine.

Commands

ts-auto-types: Generate from Selection

• Select JSON text in any file (or use the whole document if nothing is selected)
• Run from the Command Palette (Ctrl+Shift+P) or right-click in the editor
• Generated TypeScript opens in a new, unsaved document beside your JSON

ts-auto-types: Generate from JSON File

• Right-click a .json file in the Explorer
• Generates a sibling <name>.ts file automatically
• You'll be prompted to confirm before overwriting existing files

Requirements

• VS Code 1.85+
• That's all! The generator is bundled with the extension.

Features Inherited from ts-auto-types

• ✅ Union & Optional Detection — Handles string | null and optional fields perfectly
• ✅ Smart Deduplication — Reuses identical structures, no redundant interfaces
• ✅ Deep Nesting Support — Works with complex nested objects
• ✅ Real-World Data — Designed for actual API responses, databases, and configs

See the ts-auto-types documentation for more details.

Known Limitations

• Configuration overrides (literalFields, freeformFields, etc.) are only available via the CLI or programmatic API — not exposed in the extension UI yet
• Zod schema generation is planned but not yet available in the extension
