webdav

A WebDAV client written in JavaScript for NodeJS and the browser.

About

WebDAV is a well-known, stable and highly flexible protocol for interacting with remote filesystems via an API. Being that it is so widespread, many file hosting services such as Box, ownCloud/Nextcloud and Yandex use it as a fallback to their other interfaces.

This library provides a WebDAV client interface that makes interacting with WebDAV enabled services easy. The API returns promises and resolve with the results. It parses and prepares directory-contents requests for easy consumption, as well as providing methods for fetching things like file stats and quotas.

This library is compatibale with NodeJS version 6 and above (for version 4 support, use versions in the range of 1.*). Version 1.x is now in maintenance mode and will receive no further feature additions. It will receive the odd bug fix when necessary.

Please read the contribution guide if you plan on making an issue or PR.

Installation

Simple install as a dependency using npm:

npm install webdav --save

Usage

Usage entails creating a client adapter instance by calling the factory function createClient:

const { createClient } = require("webdav");

const client = createClient(
    "https://webdav.example.com/marie123",
    {
        username: "marie",
        password: "myS3curePa$$w0rd"
    }
);

// Get directory contents
const directoryItems = await client.getDirectoryContents("/");
// Outputs a structure like:
// [{
//     filename: "/my-file.txt",
//     basename: "my-file.txt",
//     lastmod: "Mon, 10 Oct 2018 23:24:11 GMT",
//     size: 371,
//     type: "file"
// }]

Make sure to read the API documentation for more information on the available adapter methods.

Authentication & Connection

webdav uses Basic authentication by default, if username and password are provided (if none are provided, no Authorization header is specified). It also supports OAuth tokens - simply pass the token data to the token field:

createClient(
    "https://address.com",
    {
        token: {
            "access_token": "2YotnFZFEjr1zCsicMWpAA",
            "token_type": "example",
            "expires_in": 3600,
            "refresh_token": "tGzv3JOkF0XG5Qx2TlKWIA",
            "example_parameter": "example_value"
        }
    }
);

webdav also allows for overriding the built in HTTP and HTTPS agents by setting the properties httpAgent & httpsAgent accordingly. These should be instances of node's http.Agent and https.Agent respectively.

Returned data structures

Detailed responses

Requests that return results, such as getDirectoryContents, getFileContents, getQuota and stat, can be configured to return more detailed information, such as response headers. Pass { details: true } to their options argument to receive an object like the following:

Property	Type	Description
data	*	The data returned by the procedure. Will be whatever type is returned by calling without { details: true }
headers	Object	The response headers.

Item stat

Item stats are objects with properties that descibe a file or directory. They resemble the following:

{
    "filename": "/test",
    "basename": "test",
    "lastmod": "Tue, 05 Apr 2016 14:39:18 GMT",
    "size": 0,
    "type": "directory"
}

or:

{
    "filename": "/image.jpg",
    "basename": "image.jpg",
    "lastmod": "Sun, 13 Mar 2016 04:23:32 GMT",
    "size": 42497,
    "type": "file",
    "mime": "image/jpeg"
}

Properties:

Property name	Type	Present	Description
filename	String	Always	File path of the remote item
basename	String	Always	Base filename of the remote item, no path
lastmod	String	Always	Last modification date of the item
size	Number	Always	File size - 0 for directories
type	String	Always	Item type - "file" or "directory"
mime	String	Files only	Mime type - for file items only

Compatibility

This library has been tested to work with the following WebDAV servers or applications:

• ownCloud
• Nextcloud
• Yandex.ru
• jsDAV
• webdav-server

Changelog

v2.0.0

2018-11-20

• Major version update!
  • Fetch has been replaced with Axios! tl;dr fetch is horrible when looking to make webdav-client compatible cross-platform. Axios is a great alternative.
  • Detailed responses now available on some methods (providing response headers, for example)
