Node.js vs. Deno: Which is better?
Compare Deno and Node.js to see which is better for your next project, the purpose of this article is to introduce you to Deno and Node.js, their differences, and how to choose the right one for your upcoming project.
What is Node.js?
In order to fix many of the design flaws mentioned at the talk, Ryan decided to introduce Deno, which ends support for legacy applications.
What is Deno?
Can we use Node.js and Deno together?
The first thing to note is that Node packages from Deno often work just fine. Fortunately, there are workarounds for most of the common stumbling blocks. In addition, Deno standard library modules can be used to “polyfill” the built-in modules of Node; CDNs can be used to access npm packages in Deno-compatible ways, and import maps can be used. Additionally, Deno supports Node compatibility mode since version 1.15.
However, Node’s plugin system does not work with Deno; Deno’s Node compatibility mode does not support TypeScript, and a few Node modules (such as VM) do not work with Deno.
Which to choose: Node.js or Deno?
Choosing the right technology for your use case depends on a variety of factors. Don’t fix an existing Node.js deployment if it’s not broken. My recommendation would be to strongly consider Deno if you intend to write a new TypeScript project. It’s pretty hard to predict whether you’re going to be successful without a proof-of-concept: Node.js packages are difficult to integrate with Deno without trying them out.
