Restizr

Restizr is a lightweight REST layer for NodeJS+ExpressJS+Sequelize: given a Sequelize model, automatically creates the REST end points (GET,PUT,POST,DELETE) at specific URL.

Example

For example, given the model

	id: { 
		type: Sequelize.INTEGER, 
		autoIncrement: true, 
		primaryKey: true
		},	
  username: { 
		type: Sequelize.STRING
		},
  password: { 
		type: Sequelize.STRING
		}
	});```

These simple commands:
```var Restizr = require('restizr');
var rest = new Restizr(app);  // ExpressJS app
rest.map(User);```

will create the following REST endpoints:
- **GET /api/user**: list first 10 records of the table "user". Accepts parameters: 
		- limit: the number of records to retrieve
		- offset: zero based index of the starting record
		- sort: field used for sorting
		- direction: could be 'asc' or 'desc'
		- filter: field used for filtering
	-	query: query used to filter
Example: /api/user?limit=20&offset=10
To override this values, just insert a onBefore middleware and add or modify keys to the object request.queryString
- GET /api/user/<id>: get the record with primary key <id> from the table "user"
- POST /api/user: create a new entry in the table "user", returns the primary key of the new record
- DELETE /api/user/<id>: delete the record with primary key <id> from the table "user"
- PUT /api/user/<id>: update the record with primary key <id> from the table "user"

Where *id* is the primary key in the MySQL  table.

## Options

- basepath(default: '/api'): change here to attach the resource REST API to a specific end point
- engine(default: 'sequelize'): the engine used for the storage, currently only Sequelize in supported
- limit(default: 10): number of records returned while listing
- onBefore,onAfter: middlewares executed at the before each request, this is a good place to check session for securing the calls to APIs
- onBeforeAll,onAfterAll: middlewares execute before and after the listing of the records
- onBeforeGet,onAfterGet:
- onBeforePost,onAfterPost:
- onBeforePut,onAfterPut
- onBeforeDelete,onAfterDelete: 

## Using middlewares

Restizr accepts a number of middlewares to be executed before or after the sigle REST operation in order to perform basic operation, for example check credentials of the client or format the output.

## Known issues
Currently the module it's in an alpha stage. Error handling is not well supported.
