output.barrel

Sets the re-export style for barrel files. pluginBarrel takes no arguments. You configure it through output.barrel instead. Set it on defineConfig to control the root barrel and the default every plugin inherits. Set it on a single plugin to override that plugin's barrel.

The type field picks the export style. { type: 'named' } writes export { Foo, Bar } from '...' from each file's named exports. { type: 'all' } writes export * from '...' for every file. false turns off barrel generation.

A plugin's output.barrel also accepts nested. With nested: true the plugin writes an index.ts in every subdirectory, each re-exporting only what sits directly inside it. The root output.barrel has no nested field, so it always stays flat.

Set barrel: false on defineConfig to disable only the root barrel. Each plugin still emits its own. Set barrel: false on a plugin to disable that plugin's barrel and drop its files from the root barrel.

Type:	{ type: 'all' | 'named', nested?: boolean } | false
Required:	false
Default:	{ type: 'named' }

NOTE

nested is plugin-level only and defaults to false. The config-level value drops it, so the root barrel type is { type: 'all' \| 'named' } \| false.

type

Export style for the barrel files.

Type:	'all' | 'named'
Required:	true
Default:	'named'

'named' (default) → src/gen/index.ts

export { getUser, User } from './api/user'
export { getPost, Post } from './api/post'
export { User } from './api/types/User'

'all' → src/gen/index.ts

export * from './api/user'
export * from './api/post'
export * from './api/types/User'

nested

Writes an index.ts in every subdirectory instead of one flat root barrel. Each one re-exports only what sits directly inside it. This field works on a plugin's output.barrel only.

Type:	boolean
Required:	false
Default:	false
