    TUS Sender

    An Uploady sender implementation of the TUS protocol.

    Supports version 1.0.0 of the TUS protocol

    Under the hood, the tus-sender uses the @rpldy/chunked-sender to upload the files as chunks


      $ yarn add @rpldy/tus-sender
      $ npm i @rpldy/tus-sender

    TUS Protocol

    On top of the Core Protocol, Uploady supports the following extensions:

    It also supports the Upload-Metadata header and will turn the destination/upload options params prop into the metadata key/value.


    Name (* = mandatory) Type Default Description
    version string "1.0.0" The tus server version
    featureDetection boolean false whether to query the server for supported extensions
    featureDetectionUrl string null URL to query for TUS server feature detection, in case it's different from upload URL
    onFeaturesDetected (string[]) => ?TusOptions void callback to handle the extensions the server broadcasts
    resume boolean true whether to store information locally on files being uploaded to support resuming
    deferLength boolean false defer sending file length to server (protocol)
    overrideMethod boolean false whether to use X-HTTP-Method-Override header instead of PATCH
    sendDataOnCreate boolean false send first chunk with create request (protocol)
    storagePrefix string "rpldy-tus" the key prefix to use for persisting resumable info about files
    lockedRetryDelay number 2000 milliseconds to wait before retrying a locked (423) resumable file
    forgetOnSuccess boolean false whether to remove URL from localStorage when upload finishes successfully
    ignoreModifiedDateInStorage boolean false ignore File's modified date when creating key for storage

    All of the chunked-sender options are supported with this sender

    When the chunked-sender parallel param is set to > 1, the Concatenation tus extension will be used. It will send the chunks as different parallel requests that are finalized once done.

    Params prop that is set on the Destination or upload options is serialized (encoded according to Tus protocol) and sent as the value of the Upload-Metadata header.

    Custom headers set on the Destination will be sent (and override existing headers) with the Creation request

    Feature Detection

    When the featureDetection option is enabled, the tus-sender will request the supported extensions' info from the server.

    In case there are options that aren't supported by the extensions list the server provides, they will be turned off.

    These options are:

    • parallel: requiring the concatenation extension
    • sendDataOnCreate: requiring the creation_with_upload extension
    • deferLength: requiring the creation_defer_length extension

    When onFeaturesDetected callback is provided, the responsibility to turn off options that aren't supported is handed over to the callback. The object returned by the callback will be merged with options being used, overriding them as needed.

    For feature detection to work, when the TUS server is served from a different origin than the page making the request, the server must allow these headers: Tus-Extension and Tus-Version to be read over CORS. Otherwise, it will not work and feature detection will be skipped.
