File Upload Configuration

Used to configure upload limits and attachment deletion callbacks in Umo Editor Mobile.

Compared with Umo Editor and Umo Editor Next, mobile places more emphasis on “previewing or playing the uploaded resource inside the current container”, and does not support the generic third-party URL-based preview approach described in the desktop documentation. Different on Mobile

Default Configuration

{
  file: {
    allowedMimeTypes: [],
    maxSize: 1024 * 1024 * 100,
  },
}

Configuration Items

file.allowedMimeTypes

Description: the list of allowed MIME types for upload. An empty array means no type restriction.

Type: Array

Default: []

Optional values: valid MIME types

Additional notes:

To allow an entire category of files, you can use values such as image/*, audio/*, and video/*.
Whether mobile file nodes, images, audio, or video uploads ultimately succeed also depends on the business implementation of onFileUpload.

file.maxSize

Description: the maximum allowed upload size, in bytes (B).

Type: Number

Default: 1024 * 1024 * 100 (100M)

file.preview

Description: file preview configuration.

Type: Array

Default: no built-in default value

file.preview can still be configured, but the mobile default configuration does not include the desktop third-party document-preview URL templates. Preview fallback for document attachments must currently be handled by business code. Support for file.preview-based preview on mobile may be considered in the future. Different on Mobile

Key Differences from Desktop

file.preview Different on Mobile: mobile currently does not support the desktop-style third-party URL-based preview capability.

File-related configuration ultimately works together with the following callbacks:

onFileUpload(file): uploads a file and returns the server result
onFileDelete(id, url, type): deletes a file or attachment resource
