========================
Aseteroid Storage Service
<a name="storage"></a>
## Storage
The `asteroid-storage-service` service is designed to make it easy to upload and download files to various infrastructure providers. **_Special attention has been paid so that methods are streams and pipe-capable._**
To get started with a `asteroid-storage-service` client just create one:
``` js
var client = require('asteroid-storage-service').createClient({
//
// The name of the provider (e.g. "file")
//
provider: 'provider-name',
//
// ... Provider specific credentials
//
});
```
Each compute provider takes different credentials to authenticate; these details about each specific provider can be found below:
* [Azure](docs/providers/azure.md#using-storage)
* [Rackspace](docs/providers/rackspace/storage.md)
* [Amazon](docs/providers/amazon.md#using-storage)
Each instance of `storage.Client` returned from `storage.createClient` has a set of uniform APIs:
<a name="container"></a>
### Container
* `client.getContainers(function (err, containers) { })`
* `client.createContainer(options, function (err, container) { })`
* `client.destroyContainer(containerName, function (err) { })`
* `client.getContainer(containerName, function (err, container) { })`
<a name="file"></a>
### File
* `client.upload(options, function (err) { })`
* `client.download(options, function (err) { })`
* `client.getFiles(container, function (err, files) { })`
* `client.getFile(container, file, function (err, server) { })`
* `client.removeFile(container, file, function (err) { })`
Both the `.upload(options)` and `.download(options)` have had **careful attention paid to make sure they are pipe and stream capable:**
### Upload a File
``` js
var storage = require('asteroid-storage-service'),
fs = require('fs');
var client = storage.createClient({ /* ... */ });
fs.createReadStream('a-file.txt').pipe(client.upload({
container: 'a-container',
remote: 'remote-file-name.txt'
}));
```
### Download a File
``` js
var storage = require('asteroid-storage-service'),
fs = require('fs');
var client = storage.createClient({ /* ... */ });
client.download({
container: 'a-container',
remote: 'remote-file-name.txt'
}).pipe(fs.createWriteStream('a-file.txt'));
```
