tus-js-client

tus is a protocol based on HTTP for resumable file uploads. Resumable means that an upload can be interrupted at any moment and can be resumed without re-uploading the previous data again. An interruption may happen willingly, if the user wants to pause, or by accident in case of an network issue or server outage.

tus-js-client is a pure JavaScript client for the tus resumable upload protocol and can be used inside browsers, Node.js, React Native and Apache Cordova applications.

Protocol version: 1.0.0

This branch contains tus-js-client v3. If you are looking for the previous major release, after which breaking changes have been introduced, please look at the v2.3.2 tag.

Example

input.addEventListener("change", function(e) {
    // Get the selected file from the input element
    var file = e.target.files[0]

    // Create a new tus upload
    var upload = new tus.Upload(file, {
        endpoint: "http://localhost:1080/files/",
        retryDelays: [0, 3000, 5000, 10000, 20000],
        metadata: {
            filename: file.name,
            filetype: file.type
        },
        onError: function(error) {
            console.log("Failed because: " + error)
        },
        onProgress: function(bytesUploaded, bytesTotal) {
            var percentage = (bytesUploaded / bytesTotal * 100).toFixed(2)
            console.log(bytesUploaded, bytesTotal, percentage + "%")
        },
        onSuccess: function() {
            console.log("Download %s from %s", upload.file.name, upload.url)
        }
    })

    // Check if there are any previous uploads to continue.
    upload.findPreviousUploads().then(function (previousUploads) {
        // Found previous uploads so we select the first one. 
        if (previousUploads.length) {
            upload.resumeFromPreviousUpload(previousUploads[0])
        }

        // Start the upload
        upload.start()
    })
})
