nodata

node-odata
==========

An odata client module for Node

Installation

``bash
npm install nodata
`




Usage

This module generates endpoints based from odata service urls

`javascript
var odata = require('nodata');

odata.createServices([{name: 'name', url: 'url1', {name: 'name2', url: 'url2']);
`

This will return a promise containing the potential generated endpoints for each service queried

`javascript
odata([{name: 'serviceOne', url: 'url1'}])
.then(function (services) {

// use services
});
`

If passed a 'authUrl', it will generate a login endpoint which can be used
to obtain a cookie for subsequent requests.
`javascript
services.login('username', 'password', function (error, cookie) {

// I Have a cookie now
});
`


Each endpoint has a get function
`javascript
var Oquery = require('nodata').Oquery;

services.someService.someEndpoint
.get(new Oquery(1).expand('someNavProp'), cookie, function (error, data) {

// check for errors and do something with data
});

// Or with a composite key
services.someService.someEndpoint
.get(new Oquery({key1: 1, key2: 2}), cookie, funciton (error, data) {

// do stuff
});
`

An insert function
`javascript
services.someService.someEndpoint
.insert(someJsonItem, cookie, function (err, data) {

// check for errors and celebrate success
});
`

An update function
`javascript
services.someService.someEndpoint
.update(1, someJsonItem, cookie, function (err, data) {

// check for errors and celebrate success
});
`

And a delete function
`javascript
services.someService.someEndpoint
.delete(1, cookie, function (err, data) {

// check for errors and celebrate success
});;
`

$3


An Oquery is built from an optional id
followed by orderby, filter, expand, skip, top, inlinecount, and select
`javascript
var Oqeury = require('nodata').Oquery;

var query = new Oquery(1).orderby('id')
.filter('state eq 2').expand('someNavProp')
.skip(5).top(10).select('someNavProp').inlinecount();

endpoint.get(query, cookie, function () {});
