Could Aleph.js be the next big React Framework?


A couple of months ago we covered Deno, a new JavaScript runtime that is attempting to dethrone Node.js as the de facto runtime for executing JavaScript.

Ironically, Deno is being developed by Ryan Dahl, the same developer who made Node.js back in 2009.

Here’s that article if you’re looking to learn more about our take on Deno:

While Deno has a lot to offer, such as built-in TypeScript support and a simpler dependency system, the biggest hurdle to its adoption is the plethora of dev tools and frameworks that are dependent on Node.js. As Deno gains traction, however, developers have begun creating new frameworks that rely on Deno instead of Node.js.

This is where Aleph.js comes in. The two most popular React frameworks for creating production-ready apps are undeniably Next.js and Gatsby; Both of which are dependent on Node.js, Aleph.js attempts to create an equivalent React framework that is fast for users and convenient for developers. In their own words:

Aleph.js gives you the best developer experience for building modern web applications:
TypeScript in Deno, ES module imports, file-system routing, SSR & SSG,
HMR with Fast Refresh, and more. No config needed.

If you’d like to hear about Aleph.js straight from the horse’s mouth, you can check out their documentation here:


How Aleph.js make React Deno-friendly

While it is technically possible to create a React application using Deno instead of Node.js, create-react-app by default is going to use NPM. Aleph.js offers that same sort of quick-start as CRA but allows you to have your React application already set up with Deno.

In fact, all it takes is a few command lines to have your Aleph.js app up and running:deno install — unstable -A -f -n aleph https://deno.land/x/[email protected]/cli.ts

aleph init my-app

cd my-app && aleph dev

In this respect, Aleph.js is paving the way for Deno to become beginner-friendly and not just a niche runtime for early adopters.

Aleph.js is essentially just Next.js built on Deno

In order to make React more SEO-friendly, Next.js was released in 2016 as a React framework that enables server-side rendering(SSR) and static-site generation(SSG). Both of these tools allow pages to be rendered relatively quickly for search engine crawlers meaning your page will rank higher.

Aleph.js seems to be open that they are essentially Next.js for Deno. They say themselves:


Just like Next.js, Aleph provides SSR and SSG out of the box in order to allow developers to create SEO-friendly apps. In addition, Aleph provides some other built-in features that don’t come out of the box in Next.js, such as:

  • Hot Reloading (Using React Fast Refresh)
  • ESM Import Syntax (No need for webpack)
  • TypeScript-Ready

Obviously, the main differentiating factor between Next.js and Aleph.js is Deno. Since Aleph is built on Deno, you have access to all the benefits of the runtime, however, you may not be able to easily use every NPM package that you want. While many packages are compatible (See here how to use them in Aleph), many packages rely on Node-specific functions, meaning they will not work in Aleph.js.

So, What’s Our Verdict?

So, what’s our verdict? Well, Aleph.js seems like a great framework, but you shouldn’t quite bet the farm on it yet. As with any early adoption, there’s going to be a lack of documentation and compatible libraries that is going to make it hard for you to do everything you need to do. Most of these issues we think you’ll encounter however are not because Aleph.js is new, but because Deno is. If Deno succeeds in becoming an industry standard, however, then Aleph.js could be the next big React framework.

In other words, we’re all for giving Aleph.js a try for your next pet project. If you’re deciding on your company’s tech stack, however, Deno probably isn’t where it needs to be yet in order to suit all your needs.
