dropbox-streaming-upload

Streaming uploads for dropbox api v2

Official js sdk by dropbox lacks streaming upload feature. This package provide just that missing feature, nothing else.

Installation

npm install --save dropbox-streaming-upload

Supported features

• Simple basic upload
• Upload session for bigger files (dropbox requires upload session for files bigger than 150mb. Though you can choose it with files of any size)
• Ability to cancel upload

Usage

const upload = require('dropbox-streaming-upload').default
upload(options).then(function(successMetadata) {

}, function(error) {

})

Options

• access_token: Dropbox access token.
• readable_stream: Readable stream to upload.
• file_size: Total size of upload in bytes. Since we just have the readable stream we need size information separately.
• destination: Destination path in dropbox where to upload the file (full file path: ie, if you are uploading roses.jpg to /weeds/ folder, then "/weeds/roses.jpg").
• forced_chunked_upload: By default library will use upload session if file_size is greater than 150mb. If you set this to true, then it will force upload session regardless of file_size.
• chunk_size: By default library will use 5mb chunk while using chunked upload. You can override it here (in bytes).
• mute: See dropbox documentation for /upload or /upload_session/finish. Default is false.
• autorename: See dropbox documentation for /upload or /upload_session/finish. Default is true.
• mode: See dropbox documentation for /upload or /upload_session/finish. Default is "add".
• client_modified: See dropbox documentation for /upload or /upload_session/finish.

Cancelling upload

const upload = require('dropbox-streaming-upload').default
const options = {
    access_token: 'token',
    readable_stream: someStream,
    file_size: totalSize,
    destination: '/mypath/myfile.ext',
}
upload(options).then(function(successMetadata) {

}, function(error) {
    if (error.message === 'user_aborted') {
        // you cancelled the upload below
    }
})

// when you want to cancel it (before upload is done/failed)
// cancel function is added to your options object by library
// calling cancel function after upload is done/failed has no effect
options.cancel()

Unit testing

• clone this repository
• run

npm install

• copy ./sample_test_data.json to ./tests/test_data.json
• fill in "access_token"
• fill in "unitTestBaseFolder". Unit test will create a tmp folder in that folder and upload files inside that (tmp folder will be removed in the end)
• update "uploads" array as needed. structure of uploads array item:

{
    "localFilePath": "localfilepath.ext",
    "destination": "./relative/to/tmp/folder/risingearth.jpg",
    "forced_chunked_upload": false,
    "chunk_size": 5e+6
}

• forced_chunked_upload and chunk_size are optional
• run

npm test
