blob-to-url

A lightweight utility for generating blob URLs and data URIs with ESM, CJS, and UMD support.

Features

• Supports ESM, CommonJS, and UMD module systems
• Generate blob URLs
• Convert blobs to data URIs
• No external dependencies
• TypeScript definitions included

API

• toBlobURL(_blob: File | Blob): Creates a blob URL
  • Returns { url: string, revoke: () => void }
• toDataURI(_blob: File | Blob): Converts blob to base64 encoded URL
  • Returns string

Usage Examples

// ESM Import
import { toBlobURL, toDataURI } from "blob-to-url";

// CommonJS Require
const { toBlobURL, toDataURI } = require("blob-to-url");

// Browser (UMD)
<script src="https://unpkg.com/blob-to-url"></script>
<script>
  const { toBlobURL, toDataURI } = window.blobToUrl;
</script>

// Blob URL Example
const { url, revoke } = toBlobURL(myBlob);
console.log(url);  // Blob URL
revoke();  // Clean up resource

// Data URI Example
const dataURI = toDataURI(myBlob);
console.log(dataURI);  // Base64 encoded URL

Build System

This package uses pkgroll for ESM and CJS build, and Rollup for UMD build.
