Informa-Db.js

Concept

The concept is to interact with storage units (such as Dbs or JSON files) by defining variables.

How to install it:

npm i informa-db.js

How to use it:

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

const Db = require('informa-db.js'); // Require the package

(async ()=>{
  const players = await new Db("players.json"); // Uses data.json to store data
  // I implemented these functions but they're boring:
  if (!players.exist(process.env.PLAYER))
    players.add(process.env.PLAYER,{
      inventory: Array(20),
      equipment: Array(5),
      temporaryData: {
        hp: 20,
        xp: 0
      }
    });
  // Instead, use this more elegant way of doing it:
  if(!players.value[process.env.PLAYER])
    players[process.env.PLAYER]={
      inventory: Array(20),
      equipment: Array(5),
      temporaryData: {
        hp: 20,
        xp: 0
      }
    };
})()

Before you ask, those all work.

Db function and properties

Db.readOnlyValue

File/collection content

Db.value<Proxy>

Proxy to this.readOnlyValue

Db.saveOnChange

If is true, runs this.update() everytime a change is made (this.add(), this.addOverwrite(), this.remove() and changing this.value )

Db.exist(index<Number, String>)

Checks if this.readOnlyValue[index] exists

Db.add(index<Number, String>, value)<Boolean, Any>

Defines this.readOnlyValue[index] to value. If this.readOnlyValue[index] already exists, will ignore and return false.

Db.addOverwrite(index<Number, String>, value)

Defines this.readOnlyValue[index] to value.

Db.remove(index<Number, String>)

Splices out/deletes this.readOnlyValue[index]

Db.update()
