light-json-database v1.0.0

Installation

npm install light-json-database

Introduction

This is very simple and extremely light database for server side NodeJS applications. It stores the data in json file generated in the current working directory.

Example

1. Creating a database

const { JsonDatabase } = require("simple-json-database");

const db = new JsonDatabase("example"); // example is database name

console.log(db.getAll()); // output: {}

2. Inserting data in database

const { JsonDatabase } = require("simple-json-database");

const db = new JsonDatabase("example"); // example is database name

db.set("name", "Jon Doe"); // db.set(key, value)

console.log(db.get("name")); // output: "Jon Doe"

console.log(db.getAll()); // output: { name: "Jon Doe" }

3. Updating data in database

const { JsonDatabase } = require("simple-json-database");

const db = new JsonDatabase("example"); // example is database name

db.set("name", "Jon Doe"); // db.set(key, value)

console.log(db.get("name")); // output: "Jon Doe"

db.set("name", "Another name"); // updating value of key "name"

console.log(db.get("name")); // output: "Another name"

4. Deleting data from database

const { JsonDatabase } = require("simple-json-database");

const db = new JsonDatabase("example"); // example is database name

db.set("name", "Jon Doe"); // db.set(key, value)

console.log(db.getAll()); // output: { name: "Jon Doe" }

db.remove("name"); // removing data of key "name"

console.log(db.get("name")); // output: {}

5. All methods

db.get(key); // return value assigned for given key

db.getAll(); // return all the data in the database

db.set(key, value); // set the value for given key
// also can be used for updating value any key that already exists in database then it will overwrite/update it.

db.setAll(data); // set/overwrite all data of database

db.remove(key); // delete the data with given key

db.removeAll(); // delete all the data in the database
