Deno vs PDF.js: What are the differences?

Introduction

Deno and PDF.js are two popular technologies used in web development. While Deno is a secure runtime for JavaScript and TypeScript, PDF.js is a JavaScript library for rendering PDF documents in the browser. In this article, we will discuss the key differences between Deno and PDF.js.

  1. Language Supported:

    • Deno supports both JavaScript and TypeScript, allowing developers to write code in either language.
    • PDF.js is primarily focused on JavaScript and is specifically designed to work with PDF documents.
  2. Runtime Environment:

    • Deno provides a secure runtime environment for executing JavaScript and TypeScript code. It has security features like permissions-based access to resources and sandboxed execution.
    • PDF.js, on the other hand, is a library that runs within the browser environment. It does not provide a separate runtime environment like Deno.
  3. Functionality:

    • Deno offers a wide range of functionalities beyond just executing scripts, including built-in module system, file system access, HTTP/HTTPS requests, and more.
    • PDF.js is specifically designed to render PDF documents in the browser. It provides features like text extraction, search functionality, annotation support, and page rendering.
  4. Security Model:

    • Deno has a security model that allows or restricts access to resources based on permissions. It provides fine-grained control over file system access, network access, and other resources.
    • PDF.js, being a library running within the browser, operates under the security model enforced by the browser itself. It does not have the same level of control over resource access as Deno.
  5. Development Community:

    • The Deno community is still growing and has a smaller user base compared to PDF.js.
    • PDF.js has been around for a longer time and has a large and active community of developers. It has been widely adopted and is used in various applications.
  6. Use Cases:

    • Deno can be used for building various types of applications, ranging from simple scripts to complex web servers and APIs.
    • PDF.js is primarily used for handling PDF documents in web applications, allowing developers to render, manipulate, and interact with PDF files.

In summary, Deno and PDF.js differ in terms of the supported languages, runtime environment, functionality, security model, development community, and use cases. Deno offers a secure runtime for executing JavaScript and TypeScript code with advanced features, while PDF.js is a JavaScript library designed specifically for working with PDF documents in the browser.
