# @google-cloud/bigtable | ||
> Google Cloud Bigtable Client Library for Node.js | ||
*Looking for more Google APIs than just Bigtable? You might want to check out [`google-cloud`][google-cloud].* | ||
|
||
- [API Documentation][gcloud-bigtable-docs] | ||
- [Official Documentation][cloud-bigtable-docs] | ||
|
||
*You may need to [create a cluster][cloud-bigtable-cluster] to use the Google Cloud Bigtable API with your project.* | ||
|
||
|
||
```sh | ||
$ npm install --save @google-cloud/bigtable | ||
``` | ||
```js | ||
var bigtable = require('@google-cloud/bigtable')({ | ||
projectId: 'grape-spaceship-123', | ||
keyFilename: '/path/to/keyfile.json', | ||
zone: 'my-zone', | ||
cluster: 'my-cluster' | ||
}); | ||
|
||
var table = bigtable.table('prezzy'); | ||
|
||
table.getRows(function(err, rows) {}); | ||
|
||
// Update a row in your table. | ||
var row = table.row('alincoln'); | ||
|
||
row.save('follows:gwashington', 1, function(err) { | ||
if (err) { | ||
// Error handling omitted. | ||
} | ||
|
||
row.get('follows:gwashington', function(err, data) { | ||
if (err) { | ||
// Error handling omitted. | ||
} | ||
|
||
// data = { | ||
// follows: { | ||
// gwashington: [ | ||

## Authentication | ||
|
||
It's incredibly easy to get authenticated and start using Google's APIs. You can set your credentials on a global basis as well as on a per-API basis. See each individual API section below to see how you can auth on a per-API-basis. This is useful if you want to use different accounts for different Google Cloud services. | ||
|
||
### On Google Compute Engine | ||
|
||
If you are running this client on Google Compute Engine, we handle authentication for you with no configuration. You just need to make sure that when you [set up the GCE instance][gce-how-to], you add the correct scopes for the APIs you want to access. | ||
|
||
``` js | ||
// Authenticating on a global basis. | ||
var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123' | ||
|
||
var bigtable = require('@google-cloud/bigtable')({ | ||
projectId: projectId | ||
}); | ||
|
||
// ...you're good to go! See the next section to get started using the API. | ||
``` | ||
|
||
### Elsewhere | ||
|
||
If you are not running this client on Google Compute Engine, you need a Google Developers service account. To create a service account: | ||
|
||
1. Visit the [Google Developers Console][dev-console]. | ||
2. Create a new project or click on an existing project. | ||
3. Navigate to **APIs & auth** > **APIs section** and turn on the following APIs (you may need to enable billing in order to use these services): | ||
* Cloud Bigtable API | ||
* Cloud Bigtable Admin API | ||
* Cloud Bigtable Table Admin API | ||
4. Navigate to **APIs & auth** > **Credentials** and then: | ||
* If you want to use a new service account, click on **Create new Client ID** and select **Service account**. After the account is created, you will be prompted to download the JSON key file that the library uses to authenticate your requests. | ||
* If you want to generate a new key for an existing service account, click on **Generate new JSON key** and download the JSON key file. | ||
|
||
``` js | ||
var projectId = process.env.GCLOUD_PROJECT; // E.g. 'grape-spaceship-123' | ||
|
||
var bigtable = require('@google-cloud/bigtable')({ | ||
projectId: projectId, | ||
|
||
// The path to your key file: | ||
keyFilename: '/path/to/keyfile.json' | ||
|
||
// Or the contents of the key file: | ||
credentials: require('./path/to/keyfile.json') | ||
}); | ||
|
||
// ...you're good to go! See the next section to get started using the APIs. | ||
``` | ||
