# File System Deployment Handler

Handles the deployment of one or more Deployment Packages to a file system.

A file system is described by a local path on disk, such as:

```
/www/files
/data
/Users/joesmith/files
```

These paths, in turn, may describe mounts that are ephemeral or non-ephemeral (such as Amazon EBS mounted drives or shared network storage).

The contents of the Deployment Packages will be deployed sequentially to the target location. If any of the content within the Deployment Packages fails to copy, it will simply be skipped. Other content objects will be allowed to proceed unabated.

## Configuration

```
{
    "deploymentPath": "{deploymentPath}"
}
```

Where `deploymentPath` is the root path on disk where things should be written.

## Mappings

The File System Deployment handler respects the `f:deployment-config` feature if applied to a node. This feature lets you configure a set of `mappings` that determine how a node's JSON object and any binary attachments should be mapped down and written to disk.

The default mappings are:

```
[{
    "type": "object-to-file",
    "config": {
        "filepath": "/{{dependency.id}}/{{dependency.typeId}}.json"
    }
}, {
    "type": "attachment-to-file",
    "config": {
        "attachmentId": "*",
        "filepath": "/{{dependency.id}}/{{attachment.filename}}"
    }
]
```

These default mappings make it so that your Node's JSON is written to disk along with any of its attachments.

- Nodes are written to disk like this:
    
    {deploymentPath}/{nodeId}/node.json
    
- Node attachments are written as well, like this:
    
    {deploymentPath}/{nodeId}/attachments/{attachmentId}.{ext}
    
- Associations are written to disk like this:
    
    {deploymentPath}/{associationId}/association.json
    
- Association attachments are written as well, like this:
    
    {deploymentPath}/{associationId}/attachments/{attachmentId}.{ext}
    

## Example

```
{
    "deploymentPath": "/www/files"
}
```
