Features

---

One can host the server on any device, and can create as many servers as they want just from a single file.

Getting started

---

The Main class is ZotDB, to initiate the class please use init() method.

Usage

---

Example available at /test folder.

To initiate:-

  ZotDB zotDB = ZotDB.init("ws://<serverip>:<port>/<dbid>");
//dbid is the root name of your json, for more details please see server logs

To navigate to some path:-

//there are server ways to navigate through your db like:- 
ZotDB zotDB = ZotDB.init("ws://<serverip>/dbid").child("abc/xyz/xyz1");

// or
zotDB.child("abc/xyz/xyz1");
// or 
zotDB.child("abc").child("xyz").child("xyz1");

//note that the above path reference will be reset everytime
// you called method to listen values or set/update values.

To Listen to Single Value:-

// snap returns an object, which you can cast to Array, String, 
// etc according to your need.
  zotDB.addSingleValueEventListener((snap) {
    print(snap);
  });

To update some value:-

//let's say we have JSON:- 
//{
//
//     "ssdd": {
//         "abc": {
//             "xyz": {
//                 "xyz1": "ayo"
//             }
//         }
//     }
//
// }

//so setValue will set (or update value if exists) some value to "hie".
  zotDB.child("abc/xyz/xyz1").setValue("hie");
//in this case the json will become:- 
//{
//
//     "ssdd": {
//         "abc": {
//             "xyz": {
//                 "xyz1": "hie"
//             }
//         }
//     }
//
// }

To remove Value:-

zotDB.child("abc/xyz/xyz1").removeValue();
//this will remove value at 'abc/xyz/xyz1'

To get unique key:-

String uid = zotDB.getPushKey();
//please check test folder for more details
