Vite Plugin Sexy Declare Type

Zero-config TypeScript declaration file generator for Vite library mode


Features

- ✨ Zero configuration - works out of the box
- 🎯 Automatic entry detection from Vite library config
- ⚡ Fast declaration generation using TypeScript Compiler API

Getting Started

$3

- Vite 7.0.0+
- TypeScript 5.0.0+

$3

``bash
pnpm add -D vite-plugin-sexy-declare-type
`

Quick Start

$3

vite.config.ts

`typescript
import { defineConfig } from 'vite';
import sexyDeclareType from 'vite-plugin-sexy-declare-type';

export default defineConfig({
build: {
lib: {
entry: './src/index.ts',
formats: ['es'],
},
},
plugins: [sexyDeclareType()],
});
`

That's it! When you run vite build, declaration files (.d.ts) will be automatically generated alongside your build output.

$3

This plugin focuses on declaration file generation, not type validation. For production builds, always run type checking first:

`json
{
"scripts": {
"build": "tsc --noEmit && vite build"
}
}
`

This ensures:

- ✅ Type errors are caught before build
- ✅ Clean build output without warnings
- ✅ Production-ready type declarations

Limitations

- Library Mode Only: Only works with Vite's library mode (build.lib)
- No tsconfig Inheritance: Uses hardcoded TypeScript options for maximum compatibility
- May generate declarations even with type errors in your code
- Run tsc --noEmit first for comprehensive type checking

Troubleshooting

$3

Check if library mode is configured:

`typescript
export default defineConfig({
build: {
lib: {
// ← Must have this
entry: './src/index.ts',
},
},
});
`

$3

The plugin uses simplified TypeScript config for broad compatibility. If you need precise type validation:

1. Run type check before build:

`bash
pnpm tsc --noEmit
`

2. Update to build script:

`json
{
"scripts": {
"build": "tsc --noEmit && vite build"
}
}
