tinydb

Purpose

TinyDB is a tiny json file based database for NodeJS.
Normally, it's better to use it for your little project.

Features

• auto save data in memory to local fild after add/delete item;
• all APIs have a callback function for data handling;
• name API refering to Mongoose;
• no third-party dependencies.

Usage

var TinyDB = require('tinydb');
test_db = new TinyDB('./test.db');

test_db.onReady = function() {
  console.log('database is ready for operating');

  // set info to DB
  test_db.setInfo('title', 'Test DB', function(err, key, value) {
    if (err) {
      console.log(err);
      return;
    }
    
    console.log('[setInfo] ' + key + ' : ' + value);
  });
  
  // get info from DB
  test_db.getInfo('title', function(err, key, value) {
    if (err) {
      console.log(err);
      return;
    }
    
    console.log('[getInfo] ' + key + ' : ' + value);
  });
  
  // do other things below
  test_db.forEach(function (err, item) {
    if (err) {
      console.log(err);
      return;
    }

    for (var key in item) {
      console.log(key + ' : ' + item[key]);
    }
  });
}
