ImageBinDB ✶

Introduction

A a NPM module designed for converting images to binary data, storing them in IndexedDB, and retrieving and converting them back to images. It's an ideal solution for web applications that require efficient image handling and storage using browser technologies.

Transform Your Web App's Image Management

ImageBinDB is a cutting-edge TypeScript NPM module, uniquely designed to revolutionize the way web applications and Progressive Web Apps (PWAs) handle images locally. It's the perfect solution for scenarios where traditional methods fall short.

Why ImageBinDB?

In the landscape of web development, efficiently managing and processing images locally in a browser or PWA has always been challenging. ImageBinDB steps in as a game-changer, offering unparalleled functionalities:

🌟 Key Features

• Effortless Image to Binary Conversion: Seamlessly convert images to binary data, bypassing the usual complexities of local image handling.
• Robust IndexedDB Storage: Leverage the power of IndexedDB for reliable and efficient storage and retrieval of your binary image data.
• Smooth Binary to Image Conversion: Transform binary data back into images effortlessly, maintaining the integrity and quality of your visuals.

Installation

npm install imagebindb

Importing the Module

import {
  imageToBinary,
  storeImage,
  retrieveImage,
  binaryToImageURL,
} from "imagebindb";

Converting an Image to Binary

const imageFile = document.getElementById("input").files[0];
imageToBinary(imageFile).then((binaryData) => {
  // Handle the binary data
});

Storing Binary Data in IndexedDB

storeImage("myDatabase", "myImageKey", binaryData).then(() =>
  console.log("Image stored successfully")
);

Retrieving Binary Data from IndexedDB

retrieveImage("myDatabase", "myImageKey").then((binaryData) => {
  if (binaryData) {
    // Handle the retrieved binary data
  }
});

Converting Binary Data Back to an Image URL

const imageUrl = binaryToImageURL(binaryData);
// Use the image URL (e.g., as the src of an img element)
