How do you know when you're using a SPA and when you're not? Seems to me, a well designed SPA is indistinguishable from a regular HTML site unless you're actively looking at the network tab. Could it be that you have a bad im

Technically, in a SPA, the browser isn't waiting. Clicking the link just triggers a function call.

I know, react is pretty big. Preact is great if using Javascript, otherwise Elm is pretty awesome as well.

How hard it is to get things right? It's not hard at all. It's builtin with frameworks like Ember or Angular, and for React you got react-router which does things correctly by default. It's just bad programming. I don't

The original post did not make that claim. It said Elm made you handle errors where they can happen. It said nothing about handling it well. Typescript will not remind you every where an error will happen, and so it is very likely that you

The difference here, is that a lazy programmer, when forced to handle this particular case, would use "Debug.crash 'should not happen'", which causes the Elm application to crash at runtime. The TypeScript program doesn&

It's not different from Elm. My point was that Elm forces you to do it, there's no way around. With Javascript+Flow or TypeScript, you need discipline to end up with code that is as reliable as Elm. Me, personally, I take short-cu

Not sure what you mean. It's normal that different packages have their own version of a given function, like List.map3, Json.map3 etc. But the implementation is different, so it's not copy-paste. It has to be this way in cases whe

Cool! Does it enforce third-party libraries as well? A thing that typescript and/or flow doesn't support, is JSON. What if a JSON object doesn't match the type? This can cause sneaky bugs later :/ I'm not saying tha

json.loads('foo.json') (what is that? python?) requires that the json matches your types exactelly. This, at least for me, is rarely the case. And yes, it is. Here is code from my own project: Json.map3 HintTemplate

Why? Elm has generics.

And Go has an entire book on how to use the database/sql package. Does that mean the database/sql package is hard? Is React difficult because there is online courses? Is Bootstrap? Of course not.

I used several FP languages before coming to Elm, like F# and ClojureScript. I prefer Elm, been using it for about two years, and haven't missed something like interfaces at all. Then again, I'm also one of those wierdos who think

by Skinney 9y ago
I've used both Typescript and Flow, and this breaks down in practice. At least, it did for me. Problem with both Typescript and Flow is that it requires discipline from you, your team, and those who provide third party libraries. If so

Or that the documentation can be improved, or the API could be improved, or a number of other things. But really, JSON encoding/decoding in Elm boils down to specifying what the type of an object's field is. If that is difficult,

> I have yet to see a FRP library that allows you to just use a component without introducing boilerplate. Given all the benefits of Elm, 6 lines of boiler plate (one line added in model, 5 lines added in update) is a small price to pay

1) I don't see a problem with this. If you have stale state, but no one sees it, who cares? Same thing regarding cleaning it up, if no one notices when, who cares? The great thing about storing all the data in a top-level datastructure

Direct use of the storage medium for everything would negate the advantages Datomic offer. The beautiful part of Datomic is that you can perform an expensive query without having any effect on other peers. Since Datomic also stores datoms i

Html.App used to be a namespace, I suspect you mean Program? In any case, how is that any more, or less, magic than Signals? Considering that the compiler has removed syntax in later versions, later versions of Elm has less magic than earli

When targeting an ES6/ES2015 compatible runtime like node or electron (which VS Code runs on), typescript essentially just strips away the type information. It only generates boilerplate when the underlying runtime doesn't support

> The more stuff that becomes compiler magic the worse the language is going to get IMO. Not sure what you mean here. Elm 0.18 has less compiler magic, not more.

Http does allow you to get the raw data and treat it as you will. It also isn't that much code. Check out the custom requests section of the documentation.

Yeah, but it's more difficult to teach others Haskell (what's a monad?) than Go. I know all three languages, I mostly prefer Go for backend work because it's easier for others to join in on. Point is that they all have their

It's compiled to erlang bytecode, yes, but not to machine code. You do have the option of doing that, but I do believe you miss out on live updates? Not sure. Erlang is great though, especially Elixir, but for some use cases Go is bett

by Skinney 10y ago
Erlang isn't necessarily better than Go in this regard. Since Erlang is interpreted and everything has to copied between processes, Go is bound to be faster than Erlang, especially when it comes to parallelism. Go is also statically ty

Here's how I view our conversation thus far. I said "Evan doesn't feel the need to add typeclasses right now." You said "He is thinking about maybe adding it in the future." Then I said "I know, that'
