Collections represent a type of content (EX, blog post, page, author, etc). We recommend using singular naming in a collection (Ex: use post and not posts).

Overview

Note: Must provide only one of fields or templates but never both

Name

The name of the collection that is used in the GraphQL schema. A name can only be used once and an error will occur if two or more collections have the same name. This name cannot have spaces, dashes, or special characters. It must be a valid GraphQL name. We recommend using singular naming in a collection (Ex: use post and not posts).

Path

The path to a folder where the content is stored. By default, the path is relative to where the CLI is running but this can be changed by using the --rootPath CLI flag. Paths do not have to be unique across collections as long as a different format or match is specified. The CLI will print a warning if there are overlapping documents.

Format

The file extension of all the documents in this collection. (Default extension is "md"). Must be one of "md", "markdown", "mdx","json", "toml", or "yaml".

The format is used to determine the parser that will be used to parse the document. The format is also used to determine the extension of the file when a new document is created. We do not support more then one format per collection but you can work around this by doing the following:

// Fields for all posts
const fields = [
  // an array of fields
]
export const defineConfig({
  schema: {
    collections: [
      {
        name: 'posts',
        label: 'Blog Posts',
        path: 'content/posts',
        format: 'mdx',
        fields,
      },
      {
        name: 'posts-json',
        label: 'Blog Posts',
        path: 'content/posts',
        format: 'json',
        fields,
      },
    ],
  },
})

match.include

A glob pattern that will be used to match a subset of the files in the path directory.

The provided pattern does not have to include the file extension. The extension will be added automatically based on the format of the collection. The final pattern that is used will be determined by match, format and path.

<path>/<match.include>.<format>

For example, if you have a collection with the following:

{
  path: 'content/posts',
  match: {
    include: '*',
  },
  format: 'md'
}

The final pattern used would be content/posts/*.md

Basic Syntax

• ? matches a single character
• * matches any number of any characters (except /)
• [abc] matches any one character in the given set
• [a-z] matches a range.
• {foo,bar} matches any whole word in the given set

Some common glob patterns

Don't match subdirectories *

Example:

{
  path: 'content/posts',
  match: {
    include: '*',
  },
  format: 'md'
}

Matches all files in content/posts folder but does not match subdirectories. It would match content/posts/hello-world.md but not content/posts/subfolder/foo.md

Match on a single file

Example:

{
  path: 'content/config',
  match: {
    include: 'index',
  },
  format: 'json'
}

This matches a single file content/config/index.json. It will not match on anything else.

Match on a set of files

Example:

{
  path: 'content/config',
  match: {
    include: '{foo,bar}',
  },
  format: 'json'
}

This matches on content/config/foo.json and content/config/bar.json. It will not match on anything else.

Match on a set of files with a prefix

Example:

{
  path: 'content/config',
  match: {
    include:'foo-{bar,baz}',
  },
  format: 'json'
}

This will match on content/config/foo-bar.json and content/config/foo-baz.json. It will not match on anything else.

match.exclude

This works the same as match.include but will exclude any files that match the pattern. This is useful for excluding files that you don't want to be editable or that are a part of a different collection.

The resulting pattern is the same except that it is prefixed with !

!(<path>/<match.exclude>.<format>)

Example with match.exclude

{
  path: 'content/posts',
  match: {
    exclude: '**/index',
  },
  format: 'md'
}

This will exclude all index.md files from your collection.

defaultItem

The default item that will be used when a new document is created. This is useful for setting default values for fields. The default item can be a function that takes in the collection and returns the default item. This is useful for setting default values that are based on the collection.

Note: This will not update existing documents. It will only be used when a new document is created.

Default Item Example

export default defineConfig({
  //...
  schema: {
    collections: [
      {
        name: 'posts',
        label: 'Blog Posts',
        path: 'content/posts',
        format: 'mdx',
        defaultItem: () => {
          return {
            title: 'New Post',
            date: new Date().toISOString(),
          }
        },
        fields: [
          {
            name: 'title',
            type: 'string',
          },
          {
            name: 'date',
            type: 'datetime',
          },
        ],
      },
    ],
  },
})

Now when a new document is created the name and date fields will have default values.

Examples

Basic Example

export default defineConfig({
  //...
  schema: {
    collections: [
      {
        name: 'posts',
        label: 'Blog Posts',
        path: 'content/posts',
        format: 'mdx',
        fields: [
          // An array of fields
        ],
      },
    ],
  },
})

Example with router and global

export default defineConfig({
  //...
  schema: {
    collections: [
      {
        name: 'posts',
        label: 'Blog Posts',
        path: 'content/posts',
        format: 'mdx',
        ui: {
          router: ({ document }) => {
            // navigate to the post that was clicked
            return `/post/${document._sys.filename}`
          },
        },
        fields: [
          // An array of fields
        ],
      },
      {
        label: 'Global',
        name: 'global',
        path: 'content/global',
        ui: {
          global: true,
        },
        format: 'json',
        fields: [
          // An array of fields
        ],
      },
    ],
  },
})

Example with default item

export default defineConfig({
  //...
  schema: {
    collections: [
      {
        name: 'posts',
        label: 'Blog Posts',
        path: 'content/posts',
        format: 'mdx',
        defaultItem: () => {
          return {
            // Return a default title and the current date as the default date
            title: 'new post',
            date: new Date().toISOString(),
          }
        },
        fields: [
          {
            label: 'Title',
            name: 'title',
            type: 'string',
          },
          {
            label: 'Date',
            name: 'date',
            type: 'datetime',
          },
        ],
      },
    ],
  },
})

Example with allowed actions

export default defineConfig({
  //...
  schema: {
    collections: [
      {
        label: 'Navigation',
        name: 'navigation',
        path: 'content/navigation',
        ui: {
          // Don't allow editors to create new navigation items
          allowedActions: {
            create: false,
            delete: false,
            createNestedFolder: false,
          },
        },
        format: 'json',
        fields: [
          // An array of fields
        ],
      },
    ],
  },
})
