sandbox

dav.Sandbox()

Create a request sandbox. There is also a deprecated interface dav.createSandbox(). Add requests to the sandbox like so:

var sandbox = new dav.Sandbox();
// sandbox instanceof Sandbox
dav.createAccount({
  username: 'Yoshi',
  password: 'babybowsersoscaryomg',
  server: 'https://caldav.yoshisstory.com',
  sandbox: sandbox  // <- Insert sandbox here!
})
.then(function(calendars) {
  // etc, etc.
});

And abort sandboxed requests as a group with sandbox.abort().

transport

dav.transport.Basic(credentials)

Create a new dav.transport.Basic object. This sends dav requests using http basic authentication.

@param {dav.Credentials} credentials user authorization.

dav.transport.Basic.send(request, options)

@param {dav.Request} request object with request info.
@return {Promise} a promise that will be resolved with an xhr request after its readyState is 4 or the result of applying an optional request `transformResponse` function to the xhr object after its readyState is 4.

Options:

  (dav.Sandbox) sandbox - optional request sandbox.

dav.transport.OAuth2(credentials)

Create a new dav.transport.OAuth2 object. This sends dav requests authorized via rfc 6749 oauth2.

@param {dav.Credentials} credentials user authorization.

dav.transport.OAuth2.send(request, options)

@param {dav.Request} request object with request info.
@return {Promise} a promise that will be resolved with an xhr request after its readyState is 4 or the result of applying an optional request `transformResponse` function to the xhr object after its readyState is 4.

Options:

  (dav.Sandbox) sandbox - optional request sandbox.

request

dav.request.addressBookQuery(options)

Options:

  (String) depth - optional value for Depth header.
  (Array.<Object>) props - list of props to request.

dav.request.basic(options)

Options:

  (String) data - put request body.

dav.request.calendarQuery(options)

Options:

  (String) depth - optional value for Depth header.

  (Number) syncLevel - indicates scope of the sync report request.
  (String) syncToken - synchronization token provided by the server.

Client

dav.Client(xhr, options)

Create a new dav.Client object. The client interface allows consumers to set their credentials and transport once and then make authorized requests without passing them to each request. Each of the other, public API methods should be available on dav.Client objects.

@param {dav.Transport} xhr - request sender.

Options:

  (String) baseUrl - root url to resolve relative request urls with.

dav.Client.send(req, options)

Send a request using this client's transport (and perhaps baseUrl).

@param {dav.request.Request} req - dav request.
@return {Promise} a promise that will be resolved with an xhr request after its readyState is 4 or the result of applying an optional request `transformResponse` function to the xhr object after its readyState is 4.

Options:

  (dav.Sandbox) sandbox - optional request sandbox.
  (String) url - relative url for request.

etc

dav.ns

Object that holds various xml namespace constants.

Example Usage

var dav = require('dav');

var xhr = new dav.transport.Basic(
  new dav.Credentials({
    username: 'xxx',
    password: 'xxx'
  })
);

dav.createAccount({ server: 'http://dav.example.com', xhr: xhr })
.then(function(account) {
  // account instanceof dav.Account
  account.calendars.forEach(function(calendar) {
    console.log('Found calendar named ' + calendar.displayName);
    // etc.
  });
});

// Or, using the dav.Client interface:

var client = new dav.Client(xhr);
// No transport arg
client.createAccount({
  server: 'http://dav.example.com',
  accountType: 'carddav'
})
.then(function(account) {
  account.addressBooks.forEach(function(addressBook) {
    console.log('Found address book name ' + addressBook.displayName);
    // etc.
  });
});

Using the lower-level webdav request api

Caution: The lower-level request api is undergoing some major reworking with frequent changes which will break consumers upgrading from earlier versions. If you're looking for a stable api and can live with the higher-level CalDAV and/or CardDAV abstractions, I strongly recommend those since that api is largely stable.

var dav = require('dav');

var client = new dav.Client(
  new dav.transport.Basic(
    new dav.Credentials({
      username: 'xxx',
      password: 'xxx'
    })
  ),
  {
    baseUrl: 'https://mail.mozilla.com'
  }
);

var req = dav.request.basic({
  method: 'PUT',
  data: 'BEGIN:VCALENDAR\nEND:VCALENDAR',
  etag: '12345'
});

// req instanceof dav.Request

client.send(req, '/calendars/123.ics')
.then(function(response) {
  // response instanceof XMLHttpRequest
});

Or perhaps without the client:

var dav = require('dav');

var xhr = new dav.transport.Basic(
  new dav.Credentials({
    username: 'xxx',
    password: 'xxx'
  })
);

// xhr instanceof dav.Transport

var req = dav.request.basic({
  method: 'PUT',
  data: 'BEGIN:VCALENDAR\nEND:VCALENDAR',
  etag: '12345'
});

// req instanceof dav.Request

xhr.send(req, 'https://mail.mozilla.com/calendars/123.ics')
.then(function(response) {
  // response instanceof XMLHttpRequest
});

For more example usages, check out the suite of integration tests.

Debugging

As of version 1.8.0, dav can tell you a lot of potentially useful things if you set the DEBUG environment variable to dav:*. You might filter them by setting DEBUG=dav:contacts, DEBUG=dav:xmlhttprequest, etc.
