## sharedb-hooks

The way to hook db-interactions on the server

### Usage

First you should require the package and init it:

server.js

```js

  

  // Add 'hook' and 'onQuery' functions to the backend 

  require('sharedb-hooks')(backend);

  

  // ...

```

then you can use the function to hook model events, for example:

```js

  

  backend.hook('create', 'todos', function(docId, value, session, backend) {

    model = backend.createModel();

    model.fetch ('todos.'+docId, function(err){

      var time = +new Date();

      model.set('todos.'+docId+'.ctime', time);

    })

  });

  

  backend.hook('change', 'users.*.location', function(docId, value, op, session, backend){

    model = backend.createModel()

    console.log('User change location HOOK');

    

    // ....

    

  });

  

  backend.hook('del', 'todos', function(docId, value, session, backend) {

    model = backend.createModel();

    

    // ....

    

  });

  

  

```
