AttachmentConfigurationService

The AttachmentConfigurationService provides customization for certain attributes of attachments displayed inside the message component. If you’re using your own CDN, you can integrate resizing features of it by providing your own handlers.

Type parameters

Name	Type
`T`	extends `DefaultStreamChatGenerics` = `DefaultStreamChatGenerics`

Properties

customGiphyAttachmentConfigurationHandler

Optional customGiphyAttachmentConfigurationHandler: (a: Attachment<T>) => AttachmentConfigration

A custom handler can be provided to override the default giphy attachment (GIFs sent with the /giphy command) configuration. By default the SDK uses fixed height (a size that’s known before the GIF is loaded), if you override that with dynamic height (for example: height: 100%) the scrolling logic inside the message list can break.

Type declaration

(a): AttachmentConfigration

Parameters

Name	Type
`a`	`Attachment`<`T`>

Returns

AttachmentConfigration

Optional customImageAttachmentConfigurationHandler: (a: Attachment<T>, type: "gallery" | "single" | "carousel", containerElement: HTMLElement) => ImageAttachmentConfiguration

A custom handler can be provided to override the default image attachment (images uploaded from files) configuration. By default the SDK uses fixed image height (a size that’s known before image is loaded), if you override that with dynamic image height (for example: height: 100%) the scrolling logic inside the message list can break.

Type declaration

customScrapedImageAttachmentConfigurationHandler

Optional customScrapedImageAttachmentConfigurationHandler: (a: Attachment<T>) => AttachmentConfigration

A custom handler can be provided to override the default scraped image attachment (images found in links inside messages) configuration. By default the SDK uses fixed height (a size that’s known before image is loaded), if you override that with dynamic height (for example: height: 100%) the scrolling logic inside the message list can break.

Type declaration

(a): AttachmentConfigration
