@nextcloud/files

Nextcloud Files helpers for Nextcloud apps and libraries.

This library provides three kinds of utils:

1. WebDAV helper functions to work with the Nextcloud WebDAV interface. Those functions are available in @nextcloud/files/dav
2. Geneal purpose function related to files or folders, like filename validation.
3. Functions and classes to interact with the Nextcloud files app, like registering a new view or a file action.

Compatibility

4.x	✅	33+
3.x	✅	26-32
2.x	❌	23-25
1.x	❌	20-22

Usage examples

Files app

Register a "New"-menu entry

The "New"-menu allows to create new entries or upload files, it is also possible for other apps to register their own actions here.

import type { Entry } from '@nextcloud/files'
import { addNewFileMenuEntry } from '@nextcloud/files'
import { t } from '@nextcloud/l10n'

const myEntry: Entry = {
	// unique ID of the entry
	id: 'my-app',
	// The display name in the menu
	displayName: t('my-app', 'New something'),
	// optionally pass an SVG (string) to be used as the menu entry icon
	iconSvgInline: importedSVGFile,
	handler(context: Folder, content: Node[]): void {
		// `context` is the current active folder
		// `content` is the content of the currently active folder
		// You can add new files here e.g. use the WebDAV functions to create files.
		// If new content is added, ensure to emit the event-bus signals so the files app can update the list.
	}
}

addNewFileMenuEntry(myEntry)
Copy

Register a sidebar tab

It is possible to provide your own sidebar tabs for the files app. For this you need to create a custom web component, which can either be done without any framework by using vanilla JavaScript but is also possible with Vue.

This example will make use of the Vue framework for building a sidebar tab as this is the official UI framework for Nextcloud apps.

The sidebar tab consists of two parts:

1. The web component which will be rendered within the sidebar.
2. A definition object that provides all information needed by the files app.

SidebarTab definition object

This object provides the requires information such as:

• The order (to ensure a consistent tabs order)
• The display name for the tab navigation
• An icon, to be used in the tab navigation
• A callback to check if the sidebar tab is enabled for the current node shown in the sidebar.
• The web component tag name

The registration must happen in an initScript.

import type { ISidebarTab } from '@nextcloud/files'

import { getSidebar } from '@nextcloud/files'
import { t } from '@nextcloud/l10n'

const MyTab: ISidebarTab = {
	// Unique ID of the tab
	id: 'my_app',

	// The display name in the tab list
	displayName: t('my_app', 'Sharing'),

	// Pass an SVG (string) to be used as the tab button icon
	iconSvgInline: '<svg>...</svg>',

	// Lower values mean a more prominent position
	order: 50,

	// The tag name of the web component
	tagName: 'my_app-files_sidebar_tab',

	// Optional callback to check if the tab should be shown
	enabled({ node, folder, view }) {  
		// you can disable this tab for some cased based on:  
		// - node: The node the sidebar was opened for  
		// - folder: The folder currently shown in the files app  
		// - view: The currently active files view  
		return true  
	},

	// Optional, recommended to large tabs  
	async onInit() {
		// This is called when the tab is about to be activated the first time.  
		// So this can be used to do some initialization or even to define the web component.  
	},
}

// the you need to register it in the sidebar
getSidebar()
	.registerTab(MyTab)
Copy

SidebarTab web component

The web component needs to have those properties:

• node of type INode
• folder of type IFolder
• view of type IView
• active of type boolean

When using Vue you need to first create the Vue component:

Copy

Which then can be wrapped in a web component and registered.

import { getSidebar } from '@nextcloud/files'
import { defineAsyncComponent, defineCustomElement } from 'vue'

getSidebar().registerTab({
	// ...

	tagName: `my_app-files_sidebar_tab`,

	onInit() {
		const MySidebarTab = defineAsyncComponent(() => import('./views/MySidebarTab.vue'))
		// make sure to disable the shadow root to allow theming with Nextcloud provided global styles.
		const MySidebarTabWebComponent = defineCustomElement(MySidebarTab, { shadowRoot: false })
		customElements.define('my_app-files_sidebar_tab', MySidebarTabWebComponent)
	},
})
Copy

WebDAV

The getClient exported function returns a webDAV client that's a wrapper around webdav's webDAV client. All its methods are available here.

Using WebDAV to query favorite nodes

import { getClient, defaultRootPath, getFavoriteNodes } from '@nextcloud/files/dav'

const client = getClient()
// query favorites for the root folder (meaning all favorites)
const favorites = await getFavoriteNodes(client)
// which is the same as writing:
const favorites = await getFavoriteNodes(client, '/', defaultRootPath)
Copy

Using WebDAV to list all nodes in directory

import {
    getClient,
    getDefaultPropfind,
    resultToNode,
    defaultRootPath,
    defaultRemoteURL
} from '@nextcloud/files/dav'

// Get the DAV client for the default remote
const client = getClient()
// which is the same as writing
const client = getClient(defaultRemoteURL)
// of cause you can also configure another WebDAV remote
const client = getClient('https://example.com/dav')

const path = '/my-folder/' // the directory you want to list

// Query the directory content using the webdav library
// `davRootPath` is the files root, for Nextcloud this is '/files/USERID', by default the current user is used
const results = client.getDirectoryContents(`${defaultRootPath}${path}`, {
    details: true,
    // Query all required properties for a Node
    data: getDefaultPropfind()
})

// Convert the result to an array of Node
const nodes = results.data.map((result) => resultToNode(r))
// If you specified a different root in the `getDirectoryContents` you must add this also on the `resultToNode` call:
const nodes = results.data.map((result) => resultToNode(r, myRoot))
// Same if you used a different remote URL:
const nodes = results.data.map((result) => resultToNode(r, myRoot, myRemoteURL))

Copy

Using WebDAV to get a Node from a file's name

	import { getClient, davGetDefaultPropfind, resultToNode, davRootPath } from '@nextcloud/files'
	import { emit } from '@nextcloud/event-bus'
	const client = getClient()
	client.stat(`${davRootPath}${filename}`, {
		details: true,
		data: davGetDefaultPropfind(),
	}).then((result) => {
		const node = resultToNode(result.data)
		emit('files:node:updated', node)
	})
