The CMS

Table of Contents

The CMS object in Tina is a container for attaching and accessing plugins, APIs, and the event bus. On its own, the CMS does very little; however, since it's the central integration point for everything that Tina does, it's extremely important!

Accessing the CMS Object

The CMS object can be retrieved from context via the useCMS hook (from anywhere within the Tina provider). Reference the available core properties to work with.

import * as React from 'react'
import { useCMS } from 'tinacms'

// <SomeComponent /> is assumed to be nested inside of the <TinaProvider> context
export default function SomeComponent() {
  const cms = useCMS()
  //...
}

Disabling / Enabling the CMS

The CMS can be enabled or disabled via methods or configuration on the CMS object. Disabling the CMS prevents the editing UI from rendering and forms from registering.

import * as React from 'react'
import { useCMS } from 'tinacms'

// <ExitButton /> is assumed to be nested inside of the <TinaProvider> context
export default function ExitButton() {
  const cms = useCMS()

  return (
    <button onClick={() => cms.toggle()}>
      {cms.enabled ? `Exit Tina` : `Edit with Tina`}
    </button>
  )
}

CMS Configuration

When instantiating the TinaCMS object, you can pass in a configuration object. This allows you to configure some options for the sidebar, toolbar, and also allows you to configure plugins and APIs declaratively.

interface TinaCMSConfig {
  enabled?: boolean
  plugins?: Plugin[]
  apis?: { [key: string]: any }
  sidebar?: SidebarConfig | boolean
  toolbar?: ToolbarConfig | boolean
  media?: {
    store: MediaStore
  }
  mediaOptions?: {
    pageSize?: number
  }
}

interface SidebarConfig {
  position?: SidebarPosition
  placeholder?: React.FC
  buttons?: {
    save: string
    reset: string
  }
}

interface ToolbarConfig {
  buttons?: {
    save: string
    reset: string
  }
}

key	usage
enabled	Controls whether the CMS is enabled or disabled. Defaults to `false`
plugins	Array of plugins to be added to the CMS object.
apis	Object containing APIs to be registered to the CMS
sidebar	Enables and configures behavior of the sidebar
toolbar	Configures behavior of the toolbar
media	Configures media.
pageSize	Sets how many media objects are displayed at a time in the media manager.

Reference

There are a number of core properties that can be helpful in working with the CMS.

TinaCMS Interface

  enabled: boolean

  registerApi(name: string, api: any): void
