webdav-sync/lib/client.js

Basic local sync to WebDAV servers

/**
 * This small webdav client is meant to replace the dependency from curl
 *
 * Example usage:
 *
 *    var client = require("./client.js");
 *    client.put("./path/to/file", "http://foo.bar/path/to/file", function (err) {
 *      if (err) { return console.log(err); }
 *      console.log("done");
 *    });
