    WebDAV client

    A WebDAV client written in JavaScript for NodeJS.

    Build Status



    This client was branched from webdav-fs as the core functionality deserved its own repository. As webdav-fs' API was designed to resemble NodeJS' fs API, little could be done to improve the adapter interface for regular use.

    This WebDAV client library is designed to provide an improved API for low-level WebDAV integration. This client uses window.fetch when available in the browser.


    Usage is very simple (API) - the main exported object is a factory to create adapter instances:

    var createClient = require("webdav");
    var client = createClient(
        .then(function(contents) {
            console.log(JSON.stringify(contents, undefined, 4));

    Each method returns a Promise.

    Adapter methods

    These methods can be called on the object returned from the main factory.

    createDirectory(remotePath [, options])

    Create a new directory at the remote path.

    createReadStream(remotePath [, options])

    Creates a readable stream on the remote path.

    Returns a readable stream instance.

    createWriteStream(remotePath [, options])

    Creates a writeable stream to a remote path.

    Returns a writeable stream instance.

    deleteFile(remotePath [, options])

    Delete a file or directory at remotePath.

    getDirectoryContents(remotePath [, options])

    Get an array of items within a directory. remotePath is a string that begins with a forward-slash and indicates the remote directory to get the contents of.

        .then(function(contents) {
            console.log(JSON.stringify(contents, undefined, 2));

    The returned value is a Promise, which resolves with an array of item stat objects.

    getFileContents(remotePath [, options])

    Get the contents of the file at remotePath as a Buffer or String. format can either be "binary" or "text", where "binary" is default.

    var fs = require("fs");
        .then(function(imageData) {
            fs.writeFileSync("./myImage.jpg", imageData);

    Or with text:

        .getFileContents("/doc.txt", "text")
        .then(function(text) {

    getFileStream(remotePath [, options])

    Get a readable stream on a remote file. Returns a Promise that resolves with a readable stream instance.

    This is the underlying method to createReadStream (uses a PassThrough stream to delay the data). Due to the requirement of waiting on the request to complete before being able to get the true read stream, a Promise is returned that resolves when it becomes available. createReadStream simply creates and returns a PassThrough stream immediately and writes to it once this method resolves.

    var fs = require("fs");
        .then(function(imageStream) {

    options is an object that may look like the following:

        "headers": {}

    Optionally request part of the remote file by specifying the start and end byte positions. The end byte position is optional and the rest of the file from start onwards will be streamed.

    var stream = client.getFileStream("/test/image.png", {
        range: { start: 0, end: 499 } // first 500 bytes


    Get quota information. Returns null upon failure or an object like so:

        "used": "12842",
        "available": "512482001"

    Both values are provided in bytes in string form. available may also be one of the following:

    • unknown: The available space is unknown or not yet calculated
    • unlimited: The space available is not limited by quotas

    moveFile(remotePath, targetPath [, options])

    Move a file or directory from remotePath to targetPath.

    // Move a directory
    client.moveFile("/some-dir", "/storage/moved-dir");
    // Rename a file
    client.moveFile("/images/pic.jpg", "/images/profile.jpg");

    putFileContents(remotePath, data [, options])

    Put some data in a remote file at remotePath from a Buffer or String. data is a Buffer or a String. options has a property called format which can be "binary" (default) or "text".

    var fs = require("fs");
    var imageData = fs.readFileSync("someImage.jpg");
    client.putFileContents("/folder/myImage.jpg", imageData, { format: "binary" });
    client.putFileContents("/example.txt", "some text", { format: "text" });

    options, which is optional, can be set to an object like the following:

        "format": "binary",
        "headers": {
            "Content-Type": "application/octet-stream"
        "overwrite": true

    options.overwrite (default: true), if set to false, will add an additional header which tells the server to abort writing if the target already exists.

    stat(remotePath [, options])

    Get the stat properties of a remote file or directory at remotePath. Resolved object is a item stat object.

    Overriding the built-in fetch function

    Under the hood, webdav-client uses node-fetch to perform requests. This can be overridden by running the following:

    // For example, use the `fetch` method in the browser:
    const createWebDAVClient = require("webdav");

    Returned data structures

    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"


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


    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
