# empower-permission

Given a permission set and a request return a permission token.

it will look in the `PermissionMap` for for a url that matches the given URL.

If found, then it will return the token string associated with that path.

Otherwise, it will return the `GeneralAccessToken` or  _'*'_.  

Paths will be parsed using the `pathToRegexp` module.

## PermissionToken

Example Token Strings:

```javascript

'token:entity:create'

'token:entity:update'

'token:entity:sub-entity:read'

```

## PermissionMap

This is a map of path strings to `PermissionTokens`

Example Map:

```json

{

  "/url/token/entity/:entityId": "url:token:entity",

  "/url/token/:tokenId": "url:token",

  "/url/token": "url:token:list",

  "/url/token/:tokenId/action": "url:token:action"

}

```

## Usage

### Building the Map from JSON

```javascript

var PermissionMap = require('empower-permission');

var map = PermissionMap.fromJson({

  "/url/token/entity/:entityId": "url:token:entity",

  "/url/token/:tokenId": "url:token",

  "/url/token": "url:token:list",

  "/url/token/:tokenId/action": "url:token:action"

}}

var token = map.getToken("/url/token/entity/1234");

console.log(token); // will output "url:token:entity"

```

### Building the Map Programmatically

```javascript

var PermissionMap = require('empower-permission');

var map = PermissionMap();

map

  .addToken("/url/token/entity/:entityId", "url:token:entity")

  .addToken("/url/token/:tokenId", "url:token")

  .addToken("/url/token", "url:token:list")

  .addToken("/url/token/:tokenId/action", "url:token:action")

var token = map.getToken("/url/token");

console.log(token); // will output "url:token:list"

```
