Tus.Net.Client 2.0.0

Tus.Net.Client

A lightweight header for connecting to a server that supports the TUS protocol. This API has two layers, the first layer (included from version 0.0.1) are built using HttpClient and HttpRequestMessage/Response setup.

Packages

Current Nuget packages are available here: https://www.nuget.org/packages/Tus.Net.Client/

Usage

Part 1/4: TusProtocol

You can use the TusProtocol class to access the following requests directly:

Core Functionality

• HEAD: Used to find how much of a file has been uploaded, it returns a header containing the number of bytes that have been uploaded
• PATCH: Used to upload a piece of a file, sequentially, by stating the start byte (used by getting the response from "HEAD") and the number of bytes to upload with this patch. It automatically adjusts for the last patch to the server.
• OPTIONS: Used to find out information about the server, for example, the optional methods that have been implemented and the TUS protocol version supported by the server.

Extension Functionality

• CREATION: Used to initiate an upload to a server, by sending the total amount of bytes that will be uploaded, and the name of a file. It will return a HttpResponseMessage containing the link of the upload as a header.
• TERMINATION: Used to delete a partial or full upload. It will return a HttpRequestMessage with a 204 Status Code if successful.

Part 2/4: TusFile

The TusFile is the class that handles uploading of Files to a server using the TUS protocol

There is a constructor, which is used to create the Tus File, and there is one method:

• UploadAsync: Used to be start or resume an ongoing upload, add any server specific headers here.

There are three events:

        /// <summary>
        /// An error that occurs during file uploading
        /// </summary>
        public EventHandler<TusErrorEventArgs> OnError { get; set; }
        
        /// <summary>
        /// An event which occurs when part of the file is successfully patched to the server
        /// </summary>
        public EventHandler<TusProgressEventArgs> OnProgress { get; set; }
        
        /// <summary>
        /// An event which occurs when the file has completed uploading
        /// </summary>
        public EventHandler<TusSuccessEventArgs> OnSuccess { get; set; }

Part 3/4: TusClient

You can use the wrapped TusClient to have a higher level of abstraction to a TUS server. Supports the following methods:

    //Used to create a URL endpoint to upload to
    CreateEndpointAsync(
            string serverEndPoint,
            FileInfo fileInfo,
            Dictionary<string, string> customHeaders,
            Dictionary<string, string> metadata)....
    
    //Gets the upload offset of a particular endpoint
    GetUploadProgressAsync(string endPoint, Dictionary<string, string> customHeaders)

    //Deletes a file using an endpoint (if supported)
    DeleteFileAsync(string endPoint, Dictionary<string, string> customHeaders)

Part 4/4: TusOptions [New in v2.0.0]

You can now pass in your own HttpClient using the TusOptions, big thank you to https://github.com/drewswiredin for the contributions.

    //Used to set options when configuring the API
    TusOptions tusOptions = new();
    tusOptions.TusVersion = "1.0.0" //Set the tus version here
    tusOptions.Logging = true //turn on logging
    tusOptions.HttpClient = HttpClient   

    //usage:
    TusProtocol tusProtocol = new(tusOptions);
