# Migrating from version `2.x` to `3.x`

The only breaking changes from `2.x` to `3.x` are listed in the [changelog](https://github.com/google/google-api-nodejs-client/blob/master/CHANGELOG.md#300---14-march-2016).

Everything else should continue to work.

# Migrating from version `1.x` to `2.x`

Code written against a `1.x` version of this library should continue to work with the `2.x` 
version. However, you may need to update any direct links in your code to
ensure better forward compatibility.

In the 2.0 version of this library, the authentication and authorization code was moved
to the new [google-nodejs-auth-library][googleauth], and a dependency was taken from 
this library to the new auth module. The list of files which were moved from this library to the 
new auth module are:

```
lib/auth/authclient.js
lib/auth/computeclient.js
lib/auth/jwtclient.js
lib/auth/loginticket.js
lib/auth/oauth2client/js
lib/pemverifier.js
lib/transporters.js
lib/utils.js
```

In each case, a stub file has been left behind in this library, forwarding the link to the
new version of the file in the [google-nodejs-auth-library][googleauth] module. If your code 
directly requires any of these files, you should add a dependency on the 
[google-nodejs-auth-library][googleauth]
module, and update your requires statement to link to the version of the file within that library.

# Migrating from version `0.x.x` to `1.x`

Many changes and improvements have been made to the `google-api-nodejs-client`
library to bring it to `1.x`. If you are starting a new project or haven't used
this library before version `1.x`, see the [README][readme] to get started
as you won't need to migrate anything.

## Discovery

In `0.x.x` the library would "discover" APIs on the fly, introducing
additional network calls and instability. That has been fixed in `1.0`.

To get the `drive` client in `0.x.x` required this:

``` js
var google = require('googleapis');
google.discover('drive', 'v2').execute(function(err, client) {
  if(err) {
    // handle error
  } else {
    // client.drive.files.insert...
  }
});
```

In `1.0` the same thing can be accomplished like this:

``` js
var google = require('googleapis');
var drive = google.drive('v2'); // no network call! :)
// drive.files.insert...
```

All APIs are immediately accessible without requiring discovery.

## Moved `resource`

We moved `resource` object from the second parameter to the `resource` property
in the first parameter object:

In `0.x.x`, a resource was specified this way:

``` js
var resourceObj = { title: 'updated title' };
client.drive.files.update({ fileId: 'abc' }, resourceObj).execute();
```

New way in `1.0`:

``` js
var resourceObj = { title: 'updated title' };
drive.files.update({ fileId: 'abc', resource: resourceObj })
```

## Removed `.execute` everywhere

Now callbacks are specified in the second parameter and `.execute` is always
implied.

The `0.x.x` way to specify a callback:

``` js
client.drive.files.get({ fileId: 'abc' }).execute(function(err, resp) {
  // handle err, resp
});
```

How to specify callback in `1.0` (in the second parameter):

``` js
drive.files.get({ fileId: 'abc' }, function(err, resp) {
  // handle err, resp
});
```

**Note:** Prior to `1.0`, the library would not execute your requests until you
specifically called `.execute`. Because this was removed in `1.0`, all requests
now immediately execute, even if a callback is not specified.

## Media uploads

Media data is now specified in a `media` parameter instead of in `withMedia()`.

The old `0.x.x` way of uploading media:

``` js
client.drive.files.insert({ title: 'Test', mimeType: 'text/plain' })
  .withMedia('text/plain', 'Hello World')
  .execute(callback);
```

The fancy new way in `1.0` using `resource` and `media` parameters:

``` js
drive.files.insert({
  resource: {
    title: 'Test',
    mimeType: 'text/plain'
  },
  media: {
    mimeType: 'text/plain',
    body: 'Hello World'
  }
}, callback);
```

**Bonus:** Media uploads now also support readable streams. Simply specify `media` as a
readable stream like this:

``` js
var fs = require('fs');

drive.files.insert({
  resource: {
    title: 'Test',
    mimeType: 'text/plain'
  },
  media: {
    mimeType: 'text/plain',
    body: fs.createReadStream('hello.txt')
  }
}, callback);
```

## Authentication

In `1.0` the ability to auth with `.withAuthClient()` and
`.withApiKey(API_KEY)` is removed.  Now just simply specify your `OAuth2`
client or API key in the `auth` parameter of any API call.
You can additionally specify it in global or service specific options to set
it as a default. See [here][options] for more information.

In `0.x.x` an OAuth2 client was specified like this:

``` js
var googleapis = require('googleapis');
var OAuth2Client = googleapis.OAuth2Client;

var oauth2Client = new OAuth2Client(/* .. */);

// ... discover plus api and get client object here ...

client
  .plus.people.get({ userId: 'me' })
  .withAuthClient(oauth2Client)
  .execute(callback);
```

In `1.0`, OAuth2Client is now available at `google.auth.OAuth2` and now you can
just put your `oauth2Client` right in the `auth` parameter. It's as easy as:

``` js
var google = require('googleapis');
var OAuth2 = google.auth.OAuth2; // changed from google.OAuth2Client
var plus = google.plus('v1');

var oauth2Client = new OAuth2(/* .. */); // initialized the same way
plus.people.get({ userId: 'me', auth: oauth2Client }, callback);
```

You can also specify an API key instead:

``` js
plus.people.get({ userId: 'me', auth: 'api key here' }, callback);
```

## Batch Requests

Batch requests were experimental before `1.0`. We have removed support for batch
requests in `1.0` due to their unpopularity and instability.
