Deno- JavaScript and TypeScript Runtime

Introduction

Almost two years ago, Ryan Dahl, the creator of Node.js, talked about the ten things he regretted about Node.js. At the same time, he introduced DENO, a prototype of a new, security-first, npm-less JavaScript, and typescript runtime. Recently DENO 1.0 released.

Why Deno?

We know that javascript is the battle field-tested Dynamic language for the web, and we cannot imagine the web industry without JavaScript. Through standard organizations like ECMA international, the language has been evolving day by day. It’s easy to explain why is the natural choice for dynamic language tooling, whether in a browser environment or as standalone processes.

NodeJS: open-source, cross-platform, JavaScript runtime environment, invented by the same author almost ten years ago. People have found it useful for web development, tooling, creating a server, and many other use cases. In the presentation, ten things regret nodejs that are discussed in more detail.

Now the changing JavaScript world, and new additions like TypeScript, building Node projects can become a problematic effort, involving managing build systems and another heavy-handed tooling that takes away from the fun of dynamic language scripting. Furthermore, the mechanism for linking to external libraries is fundamentally centralized through the NPM repository, which is not in line with the web’s ideals.

Deno

Deno is a new runtime for executing JavaScript and TypeScript outside of the web browser. Deno attempts to provide a complete solution for quickly scripting complex functionality. [code]

Will it replace NodeJS?

NodeJs is a battle field-tested platform and incredibly well supported that is going to evolve day by day.

Typescript Support

Under the hood, deno built on V8, Rust, and Tokio. The rusty_v8 crate provides high-quality Rust bindings to V8's C++ API. So it is easy to explain written in particular TypeScript means we get a lot of the benefits of TypeScript even if we might choose to write our code in plain JavaScript. So deno does not require typescript compilation setup, deno do it for automatically.

Meet Deno: The New JavaScript/TypeScript Runtime

Deno is Ryan Dahl’s (yeah, you guessed it right, the guy who created Node.js) latest venture.

But it isn’t just another JavaScript Engine. It also supports TypeScript — JavaScript’s strictly typed cousin — out of the box.

Installing Deno

On macOS, you can install Deno using Homebrew — the open-source software package manager for macOS:

brew install deno

Here’s a GIF to give you a better idea:

On Windows, Chocolately serves an alternative to macOS’s Homebrew:

choco install deno

On Linux, good ol’ curl will do the job:

curl -fsSL https://deno.land/x/install/install.sh | sh

Once Deno is installed, one can run the following command to see all the command-line options that are available:

deno --help

The output of the above command will look something like below:

Deno, a Secure Runtime for JavaScript and TypeScript

Deno is a runtime for JavaScript and TypeScript that is based on the V8 JavaScript engine and the Rust programming language. It was created by Ryan Dahl, original creator of Node.js, and is focused on productivity.

Deno: A Modern Runtime for JavaScript and TypeScript

Deno

Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.

Features

  • Secure by default. No file, network, or environment access, unless explicitly enabled.
  • Supports TypeScript out of the box.
  • Ships only a single executable file.
  • Built-in utilities.
  • Set of reviewed standard modules that are guaranteed to work with Deno.

Install

Shell (Mac, Linux):

curl -fsSL https://deno.land/install.sh | sh

PowerShell (Windows):

irm https://deno.land/install.ps1 | iex

Homebrew (Mac):

brew install deno

Chocolatey (Windows):

choco install deno

Scoop (Windows):

scoop install deno

Build and install from source using Cargo:

cargo install deno --locked

See deno_install and releases for other options.

Getting Started

Try running a simple program:

deno run https://deno.land/std/examples/welcome.ts

Or a more complex one:

const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");

for await (const conn of listener) {
  serve(conn);
}

async function serve(conn: Deno.Conn) {
  for await (const { respondWith } of Deno.serveHttp(conn)) {
    respondWith(new Response("Hello world"));
  }
}

You can find a deeper introduction, examples, and environment setup guides in the manual.

The complete API reference is available at the runtime documentation.
