## Install

```bash
pnpm add -D @nozomiishii/tsconfig
```

## Usage

Pick the variant for your setup. Each file is a working `tsconfig` you can `extends`:

- [`@nozomiishii/tsconfig`](./tsconfig.json) — base preset (`module: "preserve"` + strict defaults).
- [`@nozomiishii/tsconfig/tsconfig.bundler.json`](./tsconfig.bundler.json) — for tsup / tsdown / esbuild and other bundlers (`noEmit: true`).
- [`@nozomiishii/tsconfig/tsconfig.tsc.json`](./tsconfig.tsc.json) — for `tsc` transpile (`NodeNext` + `outDir` + sourceMap).
- [`@nozomiishii/tsconfig/tsconfig.lib.json`](./tsconfig.lib.json) — for libraries (`declaration` + `isolatedDeclarations`).
- [`@nozomiishii/tsconfig/tsconfig.nextjs.json`](./tsconfig.nextjs.json) — for Next.js (`jsx` + Next.js plugin, etc.).

After extending, add your own `include` / `exclude` / `baseUrl`:

```json
{
  "$schema": "https://json.schemastore.org/tsconfig",
  "extends": "@nozomiishii/tsconfig/tsconfig.bundler.json",
  "include": ["src/**/*"],
  "exclude": ["node_modules", "dist"]
}
```
