## EasyLite - Easy Embedded Nosql Database

[![Build Status](https://travis-ci.org/symisc/unqlite.svg?branch=master)](https://github.com/kuaikuaikim) [![Maintenance](https://img.shields.io/badge/Maintained%3F-yes-green.svg)](https://github.com/kuaikuaikim) [![GitHub license](https://img.shields.io/pypi/l/Django.svg)](https://github.com/kuaikuaikim) 

**EasyLite** is an open source embedded nosql database based on unqlite. We wrapper couples of easy CURD API for reading/writting a single file only nosql databse. EasyLite dont need any dependent library, it can run any devices easily.

## Installation

```shell

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE=Release ..

make install

```

## Usage

c++ wrapper api:  

```c++

    //set environment variables

    export LD_LIBRARY_PATH=/libeasylite.so path/

    #include "easylite_api.h"

    EasyLite* easydb = load_easylite();

    easydb->openDB("easy.db");

    StaticJsonBuffer<200> jsonBuffer;

    JsonObject& root = jsonBuffer.createObject();

    root["test"] = 100.52;

    std::string jstr;

    root.printTo(jstr);

    std::string collection_name = "user";

    int last_id_2 = fdb->insert(collection_name, jstr);

    std::string out_str;

    int count = fdb->fetchById(collection_name, last_id_2, out_str);

```

java wrapper api:  

```java

    System.loadLibrary("easylitejni");

    EasyLite easyDB = new EasyLite();

    easyDB.initLoad();

    easyDB.openDB("easy.db");

    

    //create user object

    User user=new User();

    user.setUsername("kylin");

    user.setPassword("123456");

    //object to json object

    JSONObject jsonObject=JSONObject.fromObject(user);

    //json object to json string

    String jsonStr=jsonObject.toString();

    int lastid = easyDB.insert("user", jsonStr);

    

    //select user json string by user id

    String userJsonStr = easyDB.fetchById(lastid);
