informa-db.js v5.5.0

Informa-Db.js

Now with browser support

Concept

The concept is to interact with JSON files based databases by using javascript proxies.

How to install it:

npm i --save informa-db.js

How to use it:

Here's a code example on how to use it:

const { Db, DbUtils } = require('informa-db.js');

const players = new Db('players.json');

if (!players[process.env.PLAYER]) players[process.env.PLAYER] = {
  inventory: Array(20),
  equipment: Array(5),
  hp: 20,
  xp: 0,
};

const wordDocument = new Db('calculations.json', { saveOnChange: false, exportThis: true });
// Won't work if you destructure
wordDocument.value.aaa = 123456;
wordDocument.value.bbb = wordDocument.value.aaa ** 2;

wordDocument.value.aaa >>= 2;
wordDocument.value.aaa <<= 3;
wordDocument.value.bbb >>= Math.floor(30 * Math.random());
console.log(wordDocument.value);

wordDocument.update();
wordDocument.value.aaa <<= 3;
wordDocument.value.bbb >>= Math.floor(30 * Math.random());
console.log(wordDocument.value);

All of the following also applies to the browser version
