Create Robust Web Apps with Gleam and Lustre
Рет қаралды 29,773
Күн бұрынSoftware is becoming more type-safe, but web technologies are falling behind. TypeScript alleviates some of the JavaScript woes, but it's still not enough. So what do we do?
In this video, I'll show you how to build a completely type-safe web app in Gleam using the Lustre framework.

Learned a few things about state management and effects, thanks! If you’re open to feedback, I had a couple thoughts: - The intro before coding was a bit too abstract for me. Would’ve liked slower-paced visuals or to jump straight into code - Take a breather between segments! You have a great problem-> solution structure, but I needed beats in between

Appreciate the feedback, thanks! Yeah, I agree the explanation of TEA could've perhaps been a little more concrete. As for the rest, that's just kinda my style 😅 it's polarising at times, but I do get lots of people say they enjoy not having to watch at 2x speed. Thanks again, and keep up the good work on Astro 😉

I would disagree that it's close to TypeScript at all. Gleam's type system is much more robust, and TEA is not something most TypeScript apps use.
@IsaacHarrisHolt Ай бұрын
Gleam is getting popular because it's genuinely a joy to write. It's a really good intro to FP for people who aren't familiar with it, it's really simple, it's got a great type system, the community is lovely, and the multiple compilation targets are very useful. Most of the other langs that compile to JS don't also compile to a BEAM VM language. When I do later videos in this series, you'll see how beneficial that is - you'll get full stack type safety while being able to make use of the BEAM's amazing scalability and fault tolerance.

Nice. The problem, though, is that with all these languages offering an alternative development experience (F#, Elm, PureScript, etc.), the ecosystem and libraries are so far behind modern-day frontend development that there's literally no good argument for using them other than for fun side projects in your spare time. I will try gleam for my next toy frontend app though 🍻
@IsaacHarrisHolt Ай бұрын
In some ways yes, and in others no. I agree that the ecosystem is larger in other langs, but I don't necessarily agree that there's no good argument to use them. Elm has been used in production sites just fine, and if you don't need a mega-interactive site (which is 99% of projects, to be honest), something like Lustre is probably one of the more robust ways to get there.

Please do! Let me know what you think :) in my experience, the JS output is probably slightly less performant than vanilla JS, but the type guarantees you get outweigh that tenfold.
@user-jx8uz6tb6k Ай бұрын
Does it transpile into JS? Then what stops runtime code in JS (which have weak typing) to create runtime errors? What about external data, eg from API? At least, WebAssembly is typesafe
@IsaacHarrisHolt Ай бұрын
External data can be a source of errors regardless of the language. Thankfully, Gleam decoders prevent it from crashing your code and provide a nice way to handle it. And yes, it does transpile to JS, but the type guarantees you get from Gleam's type system work really nicely, and Gleam code won't throw exceptions (unless you FFI to JS code that throws)

@IsaacHarrisHolt Ай бұрын
Fair point. It's something that's come to my mind too, honestly. You CAN break things out into components, so I imagine for things that need animations you'd do that, but you could also just write the animations in CSS (which is mostly what Svelte does anyway)

I'm an Elm orphan, I love ELM but I'm really disappointed by the fact it's more or less abandoned. I'm glad Gleam and Lustre are here to make SPA development joyful again. The difference with Elm is, as I understand, Gleam is not a pure functional language, any function can be non deterministic and have a side effect, so it's up to the developer's discipline to write pure function and managed effects while using Lustre. I think encouraging purity without imposing it is a good trade off though, especially for a language that targets mainly the BEAM and is meant for backend dev.
@IsaacHarrisHolt Ай бұрын
Gleam is wonderful, honestly. And you're right, Gleam functions can have side effects. As you said though, it's discouraged outside of a managed effect when using Lustre. Especially IO, as that'll have a performance impact and will probably block your UI updates.

@nightmare_js Ай бұрын
Yeah that’s a great point, I wonder how would it look like to build a reusable search-box component with autocomplete, multi-selection and accessibility. How many messages and update functions would be needed, it also seems like all component’s state is managed at the application level which can be overwhelming. On the other hand this seems very interesting specially for simple UIs that may not need a whole JS Framework. I definitely would love to see more of Lustre and Gleam.
@IsaacHarrisHolt Ай бұрын
For stuff like this, Lustre DOES support a component model, so you can delegate to that when you need to. You just wouldn't store your entire application's state in such a model
