blog-it-dao

blog-it-doa is a nodejs module to create services in order to perform standard CRUD operation on a mongodb collection. The whole API returns promises

Getting started

You will need a connected db instance. Then simply use the factory like this:

//assuming you have a connected db in the 'db' variable
var daoFactory=require('blog-it-dao');
var service=daoFactory(db,'a collection');

//now you can use your service
service.findOne('id').then(function(item){

});

API

Refer to the mongodb nodejs driver documentation for further details. The main difference is that blog-it-dao API does not take a callback but return a promise which will be resolve with the expected result or rejected with the error if any

collection.findOne(selector, options, function(err, item){
    if(err){
        console.log(err);
        throw err;
    }
    //do something with the item
});

will be

daoService.findOne(selector, options).then(function(item){
        //do something with the item
    },
    function(err){
        console.log(err);
    }
);

The supported method are

• findOne
• find
• insert
• remove
• save
• update

additionally, blog-it-dao expose some method "by id":

• findById(id, options): equivalent to findOne with selector {_id:id}
• removeById(id, options): equivalent to remove with selector {_id:id}
• updateById(id, options): equivalent to update with selector {_id:id}

running test

simply run npm test in a command shell
