I can't use definenuxtconfig hooks as shown in the docs
import fs from 'node:fs'
import path from 'node:path'
export default {
hooks: {
build: {
done(builder) {
const extraFilePath = path.join(
builder.nuxt.options.buildDir,
'extra-file'
)
fs.writeFileSync(extraFilePath, 'Something extra')
}
}
}
I can't use the hooks option like that because there is no hooks.build.done typescript how can I do that? It only has hooks."build:done"

Hi @zigglearner1235. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
----------------------
You're correct: in Nuxt 3/4, the recommended and type-safe way to define hooks in your
Use the flat string syntax (
nuxt.config.ts is to use the flat, colon-separated string syntax (e.g., "build:done") rather than the nested object syntax (e.g., build: { done() {} }). The nested object style is shown for convenience in some places, but TypeScript types and most documentation expect the flat string keys.
Here's how you should write your hook in nuxt.config.ts for full TypeScript support:
This approach is fully supported and type-safe. The flat string keys (like 'build:done') are the canonical way to register hooks in Nuxt 3/4, as confirmed in the official documentation and API references Nuxt Configuration: hooks.
If you use the nested object syntax, TypeScript will not recognize the types, and you may lose autocompletion and type checking. Always prefer the flat string syntax for hooks in your nuxt.config.ts for best compatibility and type safety Migration: Configuration.
If you need to see all available hooks and their string keys, refer to the Lifecycle Hooks documentation.
Summary:Use the flat string syntax (
'build:done') in your hooks object for TypeScript support. The nested object style is not type-safe in Nuxt 3/4.

@kapa.ai how can I enable nested types
Let me check the knowledge base for you again. One moment! :books:
----------------------
I'm sorry, but the knowledge sources do not contain explicit information about enabling "nested types" in the context of Nuxt or its TypeScript configuration. If you are referring to nested object syntax for hooks (e.g.,
hooks: { build: { done() {} } }), the documentation indicates that the flat, colon-separated string syntax (e.g., hooks: { 'build:done'() {} }) is the supported and type-safe approach in Nuxt 3/4 Nuxt Configuration: hooks.
If you meant something else by "nested types," please clarify your question or provide more context, and I'll do my best to assist you.
