Deno 1.0: What you need to know

Deno version 1.0 is about to land next week. LogRocket walks us through it from A to Z.

💁‍♂️ Deno is a new take on Node, as if it were designed today, by the original author of Node. Here’s a good introductory video.

`deno.town` – A web REPL for experimenting with the Deno API

deno.town is a REPL to play with the aforementioned Deno, a new take on Node as if it were designed today.

Optimizing JavaScript packages for tree shaking

Geoffrey Dhuyvetters from madewithlove on how authors of (open source) JavaScript packages can optimize their builds for tree shaking:

How do we create a package that exposes both CommonJS & ES modules while making sure we don’t break cross-platform support? Publishing 2 separate packages is an option (e.g. lodash/lodash-es). But there is a nicer, more maintainable option that obviates the need to publish twice. We can provide an extra build step that creates an ES version of our package and links it via package.json.

The package.json links both builds like so:

{
  …
  "main": "build/cjs/index.js",
  "module": "build/esm/index.js",
  …
}

Didn’t know you could als provide a module field, similar to name … handy!

Deno, a new way to JavaScript

Ryan Dahl – inventor of Node.js – has been working on Deno, a new take on Node as if it were designed today.

From async-await to ArrayBuffers, the JavaScript language has changed significantly in the decade since Node.js was designed. Deno takes advantage of these developments and incorporate lessons learned in the development of Node to provide a new JavaScript platform built on V8 and Rust. This talk will teach the audience how to get started with Deno.

I especially like the compatibility with ES Modules.
