<@Tamra> Thank you for the fast response. This miss placed and too simple question was part of my presentation on :elm: . I asked the question in the middle of the presentation. The point of the question was to point out how polite the elm-community is and how fast you can get help even with stupid questions that would normally almost anywhere else get a response like "did you try to google it".

And where does your `Main.elm` live <@Antonette>? The one, you are trying to `require` I mean
2019-02-15T08:47:16.442600
Lynne
elmlang

Do I understand correctly that you have single `Main.elm` per page? Meaning, there is basically an Elm app per page (this follows from your original post if I got it right)
2019-02-15T08:48:35.443200
Lynne
elmlang

That's the problem: I don't have a `Main.elm`. I have *many* such files in my `webpack/client/Pages` directory.
2019-02-15T08:48:37.443400
Antonette
elmlang

I see
2019-02-15T08:48:42.443700
Lynne
elmlang

So you have to require and `init` each of them separately
2019-02-15T08:48:53.444100
Lynne
elmlang

The problem is that I don't have an SPA (yet) and the cost of migrating all those separate pages to an SPA is too high for now.

Webpack simply follows your `require` statements and when it discovers an Elm file, it hands over its processing to `elm-webpack-loader`

What is everyone's opinion on calling update within update to reuse behaviour? I've found it very useful as it creates less indirection than moving the return value in a function and reusing that function.
2019-02-15T08:50:16.446100
Dayna

Maybe we messed up on that front.
2019-02-15T08:50:31.446200
Antonette
elmlang

We factored the part which requires the files.
2019-02-15T08:50:39.446400
Antonette
elmlang
general
So if you `require('./Pages/MySuperPage/Main')` (or whatever your page entry module is called) you should be able to call `init` on the required object

``` function withNodeAndPage(nodeId, pageName, doStuffWith) { const node = document.getElementById(nodeId); if (node) { const pages = require("./Pages/" + pageName + ".elm").Elm.Pages; const page = pageName .split("/") .reduce( function(accumulator, property) { return accumulator[property]; }, pages ); doStuffWith(node, page); } }; ```

(before I attempted to add the configuration for webpack that is)
2019-02-15T08:53:29.448600
Antonette
elmlang
general
Just so we're on the same page: - my initial problem is that every time a file is touched, webpack recompiles every page which takes a lot of time ; I'd rather it only recompiled only the pages that are concerned - in order to attempt to solve the problem, I modified my configuration following the advice given to use the `files` option and attempting to load only one file (the `elm/Main`) ; apparently that does not work since there is no `elm/Main` in my project
2019-02-15T08:56:11.448900
Antonette
elmlang

Aha, so we can drop the second part and only focus on the first one
2019-02-15T08:57:04.449100

Sure.
2019-02-15T08:57:11.449300

So, I stashed all the changes, and it compiles just fine (if unbearably slowly).

I had this idea for building a page from the contents of a database and building the DOM elements on the fly, but my model would have included something like `thePage: List (Html msg)` which is disallowed. Am I barking up the wrong tree?

`Browser.document` is what you want
2019-02-15T09:26:08.453700
Danika
elmlang
general
The view function now has the following signature: `view : model -&gt; Document msg` where document is: ```type alias Document msg = { title : String , body : List (Html msg) }```
2019-02-15T09:27:01.454400
Danika
elmlang
general
<@Carmon> storing `Html msg` in your model it generally a bad idea, it's better to keep your `Html msg` in your `view` and store a value in your model that you can calculate that `Html msg` from.

Storing html in the model kind of breaks the whole reactive/declarative UI idea

Yup. An answer in a minute or less. That was great :grinning:
2019-02-15T09:41:42.457200
Logan

Plus I'm guessing maybe there could be serialization issues depending on the internal implementation of the html lib?
2019-02-15T09:42:06.457400
Nana
elmlang
general
Not all UI needs to be reactive.
2019-02-15T09:44:04.457600
Danika
elmlang
general
I think really the point is to not store _functions_ in the model, not so much html in particular
2019-02-15T09:45:44.457900
Danika
elmlang
general
But then you're no longer following the Elm Architecture
2019-02-15T09:46:59.458100
Nana
elmlang

Although maybe some clever stuff could be achieved by storing html :thinking_face: could be worth exploring
2019-02-15T09:48:39.458300
Nana
elmlang

But if it's for performance reasons, `Html.lazy` would usually be a better (and faster) solution

Well a normal module with the pages exposed, but I think it would depend if the compiler supports it
2019-02-15T09:55:11.459100
Agustin
elmlang
general
compiler needs a `main`. <@Antonette> I assume you've tried the `files` approach pointing at all files that have a `main`?
2019-02-15T09:56:08.459400
Huong
elmlang
general
You mean using the `files` option in `webpack.config.js`? When I did just try what I explained that did not work with it (and I did not have a special main file but multiple page files).
2019-02-15T09:59:02.459700
Antonette
elmlang

<@Agustin> I don't quite know what the normal module with the pages exposed would look like ; if you can point to an example I'd be happy to try :)
2019-02-15T10:00:46.460000
Antonette
elmlang
general
Yeah, I think the core issue is that you want elm-webpack-load to understand that `require("./Pages/App1.elm")` should be resolved to the same bundle as `require("./Pages/App2.elm")`. I don't know if `elm-webpack-loader` has some magic around that :thinking_face:

you don't need to `require` them separately

Huong
elmlang

<https://github.com/elm-community/elm-webpack-loader#files-default---path-to-required-file> So if I follow that, having `files` with a list of the actual Elm modules that expose a `Main`, you can import any one of those and the resulting `Elm` export should have all the modules in it
2019-02-15T10:05:49.460800

Cool, thanks <@Huong> :) trying that right away.
2019-02-15T10:14:19.461000
Antonette

Ok, so I did something similar to what I had done last time: ``` // in webpack.config.js { test: /\.elm$/, exclude: [/elm-stuff/, /node_modules/], loader: 'elm-webpack-loader', options: { cwd: 'webpack/client', files: [ path.resolve(__dirname, "webpack/client/Pages/SomeIndex.elm"), path.resolve(__dirname, "webpack/client/Pages/OtherIndex.elm") ] } } // in my index.js const SomeIndex = require("./Pages/SomeIndex.elm").Elm.Pages.SomeIndex; const OtherIndex = require("./Pages/OtherIndex.elm").Elm.Pages.OtherIndex; ... ```
2019-02-15T10:27:52.461300

Good thing: it compiles and it works.
2019-02-15T10:28:40.461600
Antonette
elmlang

Less good thing: it re-compiles everything every time I change one file, even the modules I don't need re-compiled :confused:
2019-02-15T10:29:21.461800
Antonette
elmlang
general
(so it's just more configuration that seems to have no impact on what I'm trying to achieve as far as I can tell)
2019-02-15T10:29:49.462000
Antonette
elmlang
general
Nota bene: it still works even if I give an empty array to the `files` option in `webpack.config.js`. Is this option even doing anything relevant?
2019-02-15T10:33:55.462200
Antonette
elmlang

Quick check: Are you still `require`ing them separately, or do you have one single `require`, whose value is reused?
2019-02-15T10:35:04.462400
Huong
elmlang

I am still requireing them separately. I don't know how to do all in one require.
2019-02-15T10:35:33.462600
Antonette
elmlang
general
(because I don't know what the string I should give this special one-time require should be ; I tried `"elm/Main"`, `"elm/Main.elm"`, `"Main.elm"` `"Main"`, `"./elm/Main.elm"`, `"./elm/Main"`, `"./Main.elm"`, `"./Main"`, all to no avail)
2019-02-15T10:37:14.462800
Antonette
elmlang

```const Pages = require("./Pages/SomeIndex.elm").Elm.Pages; SomeIndex = Pages.SomeIndex; OtherIndex = Pages.OtherIndex; ``` I think something like this
2019-02-15T10:42:26.463100
Huong
elmlang

Yep. Nope. I only have `SomeIndex` in `Pages` and not `OtherIndex`.
2019-02-15T10:43:12.463300
Antonette
elmlang

Hm it _should_ have both :thinking_face: (at least, according to the `elm-webpack-loader` docs)

2019-02-15T10:46:19.464000

Since it still works (albeit needing multiple require) when I empty the `files` option array, maybe the paths I was giving it are failing silently?

Does anyone know if there’s a zip/unzip package yet? I wasn’t finding anything in the packages list. Since I couldn’t find one I started looking into making one but got a little stuck on how to got about implementing <https://en.wikipedia.org/wiki/DEFLATE> as it says to look at the individual bits but `elm/bytes` seems to only handle bytes. Sorry if I’m misunderstanding anything.

added `Other.elm` (which just has `module Other exposing (main)` and `main = Html.text "foo"`)
