json-file-db

What?

Very simple file wrapper to GET, PUT and DELETE javascript objects to files to use with Node.JS.

Why?

Good in the first spins of your project when you still don't need a real Db and just want to save docs to a file.

Install

npm install json-file-db

API

Save a document

var openDB = require('json-file-db');
var db = openDB('file.json');

db.put({id=12, data="someData"}, function(err){

});

Get all documents

var openDB = require('json-file-db');
var db = openDB('file.json');

db.get(function(err, data){
  console.log(data.length);
});

Get documents matching a query (using _.where())

var openDB = require('json-file-db');
var db = openDB('file.json');

db.get({name:"mike", age:10}, function(err, data){
  console.log(data.length);
});

Get documents matching an Id value

var openDB = require('json-file-db');
var db = openDB('file.json');

db.get(10, function(err, data){
  console.log(data.length);
});

Get a single document

This is a thin wrapper around get() to avoid checking for data.length before accessing data[0].

var openDB = require('json-file-db');
var db = openDB('file.json');

db.getSingle(10, function(err, data){
  console.log(data.name);
});

Delete a document

var openDB = require('json-file-db');
var db = openDB('file.json');

db.delete(10, function(err, data){
  console.log(data.Name);
});

What else?

The module is not optimized. Files are read and written completly on each operation.
It's got unit tests. run mocha to run them
