Nextcloud Chunk File Upload

Upload files to Nextcloud using chunks

Nextcloud offers a chunked upload library, which makes your life a lot easier, if you want to upload large files to your Nextcloud instance over a bad network.

Use this library if you want to build some sort of upload client in node.js and do that with the joy of Promises 🙌.

Installation

This package is published on NPM so you can simply type:

npm install --save nextcloud-chunk-file-upload

or

yarn add nextcloud-chunk-file-upload
