Deno, Rust and WebAssembly

How to extend Deno with Rust and WebAssembly functions

This page is outdated. Please visit here to how to extend Deno with Rust and WebAssembly functions.

Deno is a JavaScript / Typescript runtime written in Rust. It is based on Google V8 engine (same as Node.js) and created by Ryan Dahl -- the creator and original developer of Node.js.

Q: Is Deno going to replace Node.js?

A: It could. If it does, it will be one of the coming-to-age events for the Rust language for server-side applications. The same way Twitter made the Ruby language a legitimate choice for web apps almost 15 years ago.

Q: One of the great selling point of Deno is that it is written in Rust. Can I use Rust to enhance and extend Deno for my apps?

A: Yes. You can.

👉 Use WebAssembly to run Rust functions in Deno

👉 Use the Deno feat native extension (similar to Node.js NAPI)

Q: Are server-side WebAssembly runtimes, such as the Second State VM, going to be available for Deno?

A: Yes, we are working on it!

Q: Can you run Deno in a serverless environment?

A: Yes.

  • AWS Lambda: https://github.com/hayd/deno-lambda/tree/master/example

  • Azure Function: https://deno.land/x/azure_functions/

Q: Is there a Deno-based serverless environment to run high performance Rust functions as services?

A: We are working on that!
