Based on work done by darkrishabh Local Databse Models for React Native Apps

Getting Started

$ npm i react-native-react-native-database-model --save

----------
Usage
======================

Added better query search results and now it is possible to search any key:value pair independent of tree structure.

The ideal way to use this library is to have a db.js in your applications somewhere. Which will be required.

**DB.js**

var RNDBModel = require('react-native-db-models')

var DB = { "app": new RNDBModel.create_db('app'), "users": new RNDBModel.create_db('users'), }

module.exports = DB

and require it in your code -

var React = require('react-native'); var DB = require('./db.js'); // DB Emitter Initialized

var DBEvents = require('react-native-db-models').DBEvents var { AppRegistry, StyleSheet, Text, View, Image } = React;

// Only "all" event emitter is available

DBEvents.on("all", function(){ console.log("Database changed"); })

var App = React.createClass({ get_users: function(){ DB.users.get_all(function(result){ console.log(result); }) }, render: function(){ return ( Hello ); } });

All methods are async and therefore require a callback method.
======================
You can check all the returned data from the callback. The returned data is more than expected so modify it as per your needs.

----------
**get**

> **get(query_data, callback)**
> query_data: The data to be matched. (eg. {name: "John Doe"})

Example

DB.users.get({first_name: "Rishabh"}, function(results){ console.log(results); })

----------
**get_id**

> **get_id(id, callback)**
> id: ID of the object to be fetched.

Example

DB.users.get_id(10, function(results){ console.log(results); })

----------
**get_all**

> **get_all(callback)**
> Gets the complete table for you.

Example

DB.users.get_all(function(result){ console.log(result); })

----------
**remove**

> **remove(query_data, callback)**
> query_data: The data to be matched. (eg. {name: "John Doe"})

Example

DB.users.remove({first_name: "Rishabh"}, function(removed_data){ console.log(removed_data); })

----------
**remove_id**

> **remove_id(id, callback)**
> id: ID of the object to be deleted.

Example

DB.users.remove({first_name: "Rishabh"}, function(removed_data){ console.log(removed_data); })

----------
**add**

> **add(data, callback)**
> data: The data to be added. (eg. {name: "John Doe", age: 56})

Example

DB.users.add({first_name: "Rishabh", age: 25}, function(added_data){ console.log(added_data); })

----------
**update**

> **update(query_data, new_data, callback)**
> query_data: The data to be matched. (eg. {name: "John Doe"})
> new_data: The data to be updated. (eg. {age: 12})

Example

DB.users.update({first_name: "Rishabh"}, {age: 25}, function(updated_table){ console.log(updated_table); })

----------
**update_id**

> **update_id(id, new_data, callback)**
> id: The id of the data to be matched.
> new_data: The data to be updated. (eg. {name: "Ken"})

Example

DB.users.update_id(3, {name: "Ken", age: 12}, function(updated_table){ console.log(updated_table); })

----------
**erase_db**

> **erase_db(callback)**
> Erases the complete table.

Example

DB.users.erase_db(function(removed_data){ console.log(removed_data); })

 
 
 *More methods and features are gonna be added soon. Such as update, replace, constraints*
