@filerobot/core

@filerobot/core

The core module of the Filerobot Media Asset Widget (FMAW). This module contains all common settings shared across all FMAW plugins and can be used standalone in your upload workflows to interact with Filerobot DAM.

Usage

From NPM

The module can be installed from NPM as @filerobot/core

npm install --save @filerobot/core

then

import Filerobot from '@filerobot/core'
...
...
...
const filerobot = Filerobot(optionsObject)

From CDN

If installed via the CDN link, the plugin is inside the Filerobot global object as Filerobot.Core

const FilerobotCore = window.Filerobot.Core
...
...
...
const filerobot = FilerobotCore(optionsObject)

Module's styles

import '@filerobot/core/dist/style.css'

or via the minified versions

import '@filerobot/core/dist/style.min.css'

The Core's styles must be imported before the filerobot's plugins' styles.

Options

The Explorer supports multiple options to customize the plugin according to your needs. Required attributes are marked with (required).

An example configuration is provided below:

{
  id: 'filerobot',
  dev: false,
  container: 'try',
  securityTemplateID: '...',
  autoProceed: false,
  allowMultipleUploads: true,
  debug: false,
  logger: justErrorsLogger,
  restrictions: {
    maxFileSize: null,
    maxNumberOfFiles: null,
    minNumberOfFiles: null,
    allowedFileTypes: null
  },
  onBeforeFileAdded: (currentFile, files) => currentFile,
  onBeforeUpload: (files) => files,
}

container: string (required)

default: undefined

The container token (Filerobot token) that will be used in all the widget's modes & plugins in the whole widget ex. (listing files/folders, uploading, renaming, deleting...etc.). Register for an account at filerobot.com to obtain a token.

securityTemplateID: string (required)

default: undefined

The Security Template ID used for the the FMAW to request session-specific API access keys, also known as SASS key. Security Templates are created in the Filerobot Asset Hub and define permissions and validity for SASS keys. They work similar to oAuth2 tokens.

id: string (optional)

default: 'filerobot'

The unique indentifier used for identifying the widget's instance (# in HTML selector).

dev: boolean (optional)

default: false

Enables the development mode which sends all requests to development server if provided with true value, otherwise all the endpoints used would refer to the production server.

autoProceed: boolean (optional)

default: false

If set to true, the upload process of one or multiple assets will start automatically after drag and drop in the upload area or selection from the user's local explorer. If set to false, the pre-upload features will be available to the user before starting the upload via the Upload button.

allowMultipleUploads: boolean (optional)

default: true

If set to false, only one upload will be possible simulateneously.

debug: boolean (optional)

default: false

Turns on the debug mode by exposing the plugin's debug information to the global window object and turns on the logger.

logger: object (optional)

default: errors only logger

errorsLogger = {
  debug: (...args) => {},
  warn: (...args) => {},
  error: (...args) => console.error(`[Filerobot] [${getTimeStamp()}]`, ...args)
}

restrictions: object (optional)

default:

{
  maxFileSize: null,
  maxNumberOfFiles: null,
  minNumberOfFiles: null,
  allowedFileTypes: null
}

Upload restrictions:

• maxFileSize (integer | null - optional): maximum file size in bytes.

• minNumberOfFiles (number | null - optional): minimum number of files before upload can start.
• allowedFileTypes (array | null - optional): accepted file types or extensions, eg. ['image/*', 'image/jpeg', '.jpg'].

Upload restrictions can also be governed in the backend by the Security Template configured.

onBeforeFileAdded: (currentFile, files) => ... (optional)

default: (currentFile, files) => currentFile

Gives the possibility to do some checks before adding the file to the state's object,

• if the function returns true, the file is added to the state.
• if the function returns a modified file object the returned object would be added to the state.
• if the function returns false, the file is not added to the state.

onBeforeUpload: (files) => ... (optional)

default: onBeforeUpload: (files) => files

Gives the possibility to do some checks before starting the upload process

• if the function returned true the upload would start.
• if returned files object the returned object would be processed.
• if returned false the uploading process won't start.

locale: object (optional)

default: default locales inside lib/defaultLocale.js

You can override the default labels and translations by specifying an alternative locale file path here. You could pass any object/translation file from @filerobot/locale.
