# passport-strategy
[](http://travis-ci.org/jaredhanson/passport-strategy)

An abstract class implementing [Passport](http://passportjs.org/)'s strategy
API.
## Install
$ npm install passport-strategy
## Usage
This module exports an abstract `Strategy` class that is intended to be
subclassed when implementing concrete authentication strategies. Once
implemented, such strategies can be used by applications that utilize Passport
middleware for authentication.
#### Subclass Strategy
Create a new `CustomStrategy` constructor which inherits from `Strategy`:
```javascript
var util = require('util')
, Strategy = require('passport-strategy');
function CustomStrategy(...) {
Strategy.call(this);
}
util.inherits(CustomStrategy, Strategy);
```
#### Implement Authentication
Implement `autheticate()`, performing the necessary operations required by the
authentication scheme or protocol being implemented.
```javascript
CustomStrategy.prototype.authenticate = function(req, options) {
// TODO: authenticate request
}
```
## Tests
$ npm install
$ npm test
