Pergamum

JSON database through the use of SODB and file watchers.

Pergamum allows you to have multiple clients connected to the same folder all receive updated data as soon as another writes it.

Install

Install Pergamum from NPM

npm install --save pergamum

Usage

const Pergamum = require('pergamum')

const path = require('path')

var db = new Pergamum({
  dir: path.join(__dirname, 'data'),
  create: true, // If the folder does not exist create it
  callback: function(){
    db.createStore('tasks', function(){
      db.addEntry('tasks', {task: 'learn pergamum', complete: false}, function(record){
        // Your database folder will now have a tasks.json with this task in.
      })
    })
  }
})

From here you can use SODBs methods with an additional argument for the store.

var incompleteTasks = db.where('tasks', {complete: false}, function(tasks){
  // tasks is an array of SODB entries.
})

Warning

Pergamum is very early in development. There will be edge cases where it fails. If you use it in production ensure that there is regular backups of your data.
