JSON ODM

by Konsultaner, Richard Burkhardt

This Project aims to be provide a json object document mapper.
Why would I need this?
There are many cases where you do not want to have the server query your data. You may also see this mapper as a fancy way to filter your data or prepare a view model. The original use case was an ionic app that was not interactive so providing a server backend was not needed, but structuring my data into joinable collections seemed very helpful.

And if you can use a server you may consider our new WebSocket server project "connectanum" for Publish/Subscribe and RPC communication

If you like the project please support it with a star here on GitHub

If commercial support is needed please contact me.

Docs

You can find the documentation here or compiled to the folder /docs/gen/*.

Road map

Install from NPM-Package

npm install json-odm

Build and run tests, both minified and unminified

npm install json-odm
cd npm_modules/json-odm/
npm install
gulp

Browser Support

Unit test ran successfully under Chrome,iOS7+,IE9+,Firefox,Android 4.4.2+
To be tested: Safari on OSX, IE8(test driver does not run in IE < 9 so it will be hard to test)

Example

This is only a basic example. Find a lot more in the docs, i.e. how to use $geoWithin

<!-- add minified version from https://github.com/konsultaner/jsonOdm/tree/master/bin to the html head -->
<script type="text/javascript" src="js/json.odm.min.js"></script>
// initialize The mapper
var odm = new jsonOdm();
// add a source to the mapper
odm.addSource('people',{
   "Person" : [
       {"id":1,"name":"Richi",jobId:1,hobbyIds:[1,3,4]},
       {"id":2,"name":"Dave",jobId:2,hobbyIds:[2,4]},
       {"id":3,"name":"Tom",jobId:3,hobbyIds:[3,5]},
       {"id":4,"name":"Lisa",jobId:4,hobbyIds:[1,2,3]},
       {"id":5,"name":"Hanni",jobId:3,hobbyIds:[1,5]},
       {"id":6,"name":"Selma",jobId:3,hobbyIds:[1,4]},
       {"id":7,"name":"Ralf",jobId:1,hobbyIds:[4,3]}
   ],
   "Jobs" : [
       {"id":1,"name":"plumber"},
       {"id":2,"name":"programmer"},
       {"id":3,"name":"chef"},
       {"id":4,"name":"hairdresser"}
   ],
   "Hobbies" : [
       {"id":1,"name":"swimming"},
       {"id":2,"name":"cycling"},
       {"id":3,"name":"fishing"},
       {"id":4,"name":"coding"},
       {"id":5,"name":"dancing"}
   ]
});
// instantiate a collection object
var people = new jsonOdm.Collection('Person');
people.$hasOne("jobId","id","Jobs","job");
people.$hasMany("hobbyIds","id","Hobbies","hobbies");

var q = people.query();
// get all hairdresser and plumber
var hairdresser = q.$or(
   q.$branch("jobId").$eq(1)
   q.$branch("jobId").$eq(4)
).$all();

// get all but hairdressers and plumbers
var hairdresser = q.$and(
   q.$branch("jobId").$ne(1)
   q.$branch("jobId").$ne(4)
).$all();

// delete all plumbers
q.$branch("job","name").$eq("plumber").$delete();
