Bulbat

The name is from random generated Pokémon, between Bulbasaur and Golbat.

This is in-memory quick storage that could be synced to the disk if neaded inside an encrypted file.

WARNING

The current implementation is pretty basic in terms of encryption. So don't put any sensitive data

Usage

Install the package with

npm install --save bulbat

Import and use

import { Database } from 'bulbat';

const db = new Database();

const post = {
  id: 42,
  title: 'Welcome to my blog!',
  content: '...'
};

db.collection('posts').insert(post);

db.collection('posts').data.map((post) => {
  console.log(post);
});

You could use the Collection only without the need of the Database instance:

import { Collection } from 'bulbat'

const posts = new Collection('posts');

posts.insert(/* data */);

posts.data.map((post) => {
  console.log(post)
});

The collection provide an reduce method that could be used to sort or change the content of the collection, internal state. Right now the only way to make bulk actions to the storage.

import { Collection } from 'bulbat';

const col = new Collection('posts');

// insert some data into the collection

col.reduce((result, post) => {
  if (post.status !== 'deleted') {
    result.push(post);
  }
  return result;
});

col.data
// => only posts that are not `deleted`

Collection require to have name as first argument - this is the minimum requirment. CollectionProps could be passed to all collections when using the Database and overwrite/extend for each collections from the Collection constructor or as second argument to Database#add method.

const db = Database({ path: `./db` });
db.add('posts', { path: './posts' });

Encryption, every collection by default will try to store it's state to the disk inside a encrypted file.The file is locked with default password of '<empty-string>'. You could change this by passing password to all collections or per collection - you will need to set CollectionProps.password. Created collection could not change there password (for now).

const db = Database({ password: 'not-qwerty' });
db.add('posts', { password: 'qwerty' }); // will use 'qwerty' for password
db.add('images'); // will use 'not-qwerty' as password
