How Keystatic organises your content

Keystatic gives you a lot of control and flexibility with where your content gets generated, both at the collection/singleton level, and at the field level for certain field types, like images.

Let’s start with the collection/singleton options.

Collections & Singletons output

You can define where Keystatic should store collection entries and singletons via the path property in the collection/singleton top-level options.

// Keystatic config
export default config({
  collections: {
    posts: collection({
      label: 'Posts',
      path: 'content/posts/*/',
      // ...
    })
  },
  singletons: {
    settings: singleton({
      label: 'Settings',
      path: 'content/posts/',
      // ...
   })
  }
})

The optional trailing slash / on that path has an impact on the content structure - read below for more details on collection paths and singleton paths.

Collections

The path property for collections is a string that contains a * wildcard representing the slug of an entry.

If not specified, the default path value will be {collection-name}/*/.

⚡️

Why a*symbol?

The * wildcard in the path is useful when you want to collocate Keystatic’s output with your existing source code, that may be nested a few levels deep inside an entry you’re writing content for.

For example, you may be writing documentation for Design System components.

Say you want Keystatic to output your documentation entries in packages/design-system/{component-name}/docs/.

You can use path: ‘packages/design-system/*/docs/’ to do just that 👍

Paths ending with a trailing slash /

If the path ends with a trailing slash /, each entry will be created in its own directory named after the slug:

collection-name
  slug
    index.yaml
    other.mdoc

Say you create two entries in the posts collection, where the path is set to 'content/posts/*/'.

Since there is a trailing slash in the path, the generated output will look like so:

content
  posts
    my-first-post
      index.yaml
      other.mdoc
    my-second-post
      index.yaml
      other.mdoc

Paths ending without a trailing slash

If the path does not end with a trailing slash, entries’ index files will be created immediately inside the collection directory:

collection-name
  slug.yaml
  slug
    other.mdoc

Say you create two entries in the posts collection, where the path is set to 'content/posts/*'.

Since there is no trailing slash in the path, the generated output will look like so:

content
  my-first-post.yaml
  my-first-post
    other.mdoc
  my-second-post.yaml
  my-second-post
    other.mdoc

Singletons

The path property for singletons does not contain a * wildcard.

If not specified, the default path value for singletons will be {singleton-name}/.

Paths ending with a trailing slash /

If the path ends with a trailing slash /, the singleton’s content ill be created in its own directory named after the slug:

singleton-name
  slug
    index.yaml
    other.mdoc

Paths ending without a trailing slash

If the path does not end with a trailing slash, the singleton’s index file will be created immediately inside the singleton directory:

singleton-name
  slug.yaml
  slug
    other.mdoc

Individual fields output

Right now, only images allow you to decide where content should be generated, independently of the collection/singleton level path settings.

⚡️

The reason for this is certain frameworks (like Next.js) need your images to be in a specific directory (like /public) to be easily accessible.

Instead of generating all your content inside the public directory to satisfy this requirement, Keystatic lets you define a specific path for your images only.

Here’s how you define where an image gets generated for a given collection or singleton:

// In the context of a `posts` collection...
coverImage: fields.image({
  label: "Cover Image",
  directory: "public/images/posts",
}),

Regardless of where the posts entries are created, the coverImage image will be generated in public/images/posts/{post-slug}.
