Develop Preview Ship For The Best Frontend Teams

Our built-in CI/CD system triggers for every code change. Reliable live-editing experience for your UI components. There are a number of bindings available today to existing frameworks, but those looking for a mature, easy to use, and completely Rust-based solution will most likely find themselves out of luck. Let’s push those servers to the edge while we’re at it.

rust for FrontEnd Development

As a low level language, Rust is perfectly suitable for making user interfaces the old fashioned way, with native APIs. However, competing in today’s world typically means supporting many platforms, and that makes using native APIs an unattractive option for many. Reading data out of Redis is a very similar process, just inverted.


However, in order to do this, NodeGui requires some adjustments to your application code in order for it to translate your components into Qt components. While I’m sure this certainly would have worked, I wasn’t interested in this solution because I wanted to use exactly what I already knew, without requiring any adjustments to my Svelte files. By contrast, Tauri achieves its savings by wrapping the operating system’s native webviewer — for example, Cocoa/WebKit on macOS, gtk-webkit2 on Linux, and Webkit via Edge on Windows. Webviewers are effectively browsers, which Tauri uses because they already exist on your system, and this means that our applications can remain pure web development products.

At Cloudflare, we have a great product called Workers KV which is a key-value storage layer that replicates globally. It can handle millions of keys, each of which is accessible from within a Worker script at exceptionally low latencies, no matter where in the world a request is received. Workers KV is amazing — and so is its pricing, which includes a generous free tier. Then we declare all the possible routes of our application. A hard and fast introduction to Rust-to-WASM compilation and using web-sys to write Rust that runs in the browser. For more information about Rust and WebAssembly, check out the Rust and WebAssembly Book.

So now it’s Thursday and I still haven’t written any Redis code, but at least I know how to connect the two halves of my application’s brain together. It was time to comb back through the client-side code and replace all TODOs inside event handlers and connect them to the real deal. However, that’s not exactly what I had in mind for my desktop application’s use case. The distDir relates to where the built production-ready assets are located. This value is resolved from the tauri.conf.json file location, hence the ../ prefix. Vercel combines the best developer experience with an obsessive focus on end-user performance.

A tour of a few libraries and frameworks to use that make application development generally easier . This means that you can take advantage of the amazing Rust ecosystem on the browser! Rust and WebAssembly integrate with existing Javascript tooling like NPM, Webpack, and ECMAScript modules!

With these savings, the bare minimum Tauri application is less than 4MB, with average applications weighing less than 20MB. In my testing, the bare minimum NodeGui application weighed about 16MB. Test from the perspective of your users, on every platform. Developers love Next.js, the open source React framework Vercel built together with Google and Facebook.

rust for FrontEnd Development

Many existing apps are in the process of migrating to GraphQL. The Seed templating system uses a macro syntax that makes Rustaceans feel right at home. This means linting, formatting, and commenting will work, and it’s all in Rust. This is opposed to a JSX-like syntax that relies on IDE extensions to improve the developer experience. I built one of the first big SPAs (remember Grooveshark?), but I’ve shied away from them ever since. With an SPA, the entire site or app lives in a single HTML file.

Frontend Predictions For 2021

This was great because Redis already treats keys as a first-class citizen and offers the sorting and filtering behaviors I wanted (aka, I can pass along the work instead of implementing it myself!). And then, of course, Redis is easy to install and run either locally or in a container, and there are many hosted-Redis-as-service providers out there if someone chooses to go that route. SvelteKit uses app.html as a default base template, but old habits die hard. Well, recently, I was lucky enough to join Cloudflare! Even more so, I joined just before the quarter’s “Quick Wins Week” — aka, their week-long hackathon. And given that I hadn’t been around long enough to accumulate a backlog , you best believe I jumped on the opportunity to fulfill my own wish.

There are some awesome Rust and WebAssembly projects out there. For example, Yew and Seed let you create front-end web apps with Rust in a way that feels almost like React.js. And, of course, SvelteKit certainly made this timeline possible. Not only did it save me a half-day-slog configuring my toolbelt, but the instant, HMR development server probably saved me a few hours of manually refreshing the browser — and then the Tauri viewer.

Tauri allows us to send messages across this bridge so that the two worlds can communicate with one another. Before Wednesday ended, I had to get my Svelte to talk to my Redis. After poking around a bit, I noticed that all the important stuff seemed to be happening inside the src-tauri/ file.

This starts to matter when dealing with millions of keys which, as mentioned, is not uncommon with Workers KV. So, with the intro out of the way, let me tell you how I built Workers KV GUI, a cross-platform desktop application using Svelte, Redis, and Rust. In this post, I go into details about building a real production app with Hotwire and what we learnt as a team, plus some of the things we don’t like and the problems we bumped into. There’s lots of info out there about building a simple app with Turbo, but there’s very limited content about architecting apps, scaling or building anything that’s not simply a blog. This time we’re arguing whether or not single-page apps were a big mistake. This premise was inspired by Chris Ferdinandi’s SPAs were a mistake post.

Basically the “…but it works on my machine” problem went away because all of the users were running the exact same localhost setup. Through the Node.js layer, you could interact with the filesystem, run servers on multiple ports, or include a bunch of node_modules to — and I’m just spit-balling here — connect to a Redis instance. Luckily, there are a few alternatives Buttons or Dropdowns in FrontEnd Development — I evaluated Svelte NodeGui and Tauri. Both choices offered significant application size and utilization savings by relying on native renderers the operating system offers, instead of embedding a copy of Chrome to do the same work. NodeGui does this by relying on Qt, which is another Desktop/GUI application framework that compiles to native views.

  • Rust does not have a dominant framework at the level of Django or Rails.
  • It was time to comb back through the client-side code and replace all TODOs inside event handlers and connect them to the real deal.
  • For more information about Rust and WebAssembly, check out the Rust and WebAssembly Book.
  • This is where all Tauri-specific files live, which is nice for organization.
  • Our built-in CI/CD system triggers for every code change.
  • Developers love Next.js, the open source React framework Vercel built together with Google and Facebook.

For example, when the /viewer started up, all the keys should be listed and ready to go. In Svelte terms, that means I need to dispatch a Tauri command when the /viewer component mounts. Additionally, clicking on a key name in the sidebar reveals additional “details” about the key, including its expiration , its metadata , and its actual value .

Next.js powers the biggest websites like Patreon, for use cases in e-commerce, travel, news, and marketing. Our platform enables frontend teams to do their best work. With performance and security at the center, Rust is the language for the next generation of apps. This is a lengthy, sprawling piece on the evolution of frontend development by someone who really gets the web. It also has its own art-direction and design so you’ll want to read it onsite vs in an Instapaper-alike.

A Solid Option For Building Uis

Connect your pages to any data source, headless CMS, or API and make it work in everyone’s dev environment. Vercel is the best place to deploy any frontend app. Start by deploying with zero configuration to our global edge network.


But I digress… read this post it’s a good one for sure. My app is basically a browser tab running Svelte, right? Having thought about it for a bit, I decided to use Redis as my backing store because it also is a key-value store.

Digging into and/or adding Rust parts was “bonus material” and is only required if my app requires it. The above defines the redis crate as a dependency and opts into the “tokio-native-tls-comp” feature, which the documentation says is required for TLS support. This creates a src-tauri directory alongside the src directory . This is where all Tauri-specific files live, which is nice for organization.

Native Notifications

At a high-level, once a Redis connection is established using the given details, a SYNC button is accessible in the /viewer route. When this button is clicked (and only then — because of costs) a JavaScript function is called, which is responsible for connecting to the Cloudflare REST API and dispatching a “redis_set” command for each key. This redis_set command is defined in the Rust layer — as are all Redis-based commands — and is responsible for actually writing the key-value pair to Redis. Current approaches to building GUIs in Rust include interfacing with Electron and building GUIs with HTML , while others have taken to using graphics APIs and various wrappers to emulate classical widgets. At this point, it’s Wednesday afternoon of Quick Wins week, and — to be honest — I’m starting to get nervous about finishing before the team presentation on Friday. Because I’m already halfway through the week, and even though I have a good-looking SPA inside a working desktop application, it still doesn’t do anything.
