Basically, I have a model where I want to decode `buildNumber` but it might be in Json as `build` or `buildNumber` and I'm struggling to figure out how to do that.

string or null. basically I'm hitting an API that has versioned and not all data has updated. what we had before when it was just `buildNumber` was this:

`|> Json.Decode.Pipeline.optional "buildNumber" (Decode.nullable Decode.string) Nothing`

You can build a decoder that uses the first location that works:
```
oldOrNewBuildNumber : Decoder String
oldOrNewBuildNumber =
Decode.oneOf
[ Decode.field "buildNumber" Decode.string
, Decode.field "build" Decode.string
]
```
|
2019-02-13T16:50:27.254500
|
Carman

You can then plug this into a pipeline using `Json.Decode.Pipeline.custom`

If the log in is success, you have a CMD that communicates to the port that is defined in the html/index.js (elm initialization)

That port sends back the session through a port. And the Login page is subscribed to listen to those changes

Morning Everyone. I'm implementing a kind of i18n into an elm application. I have a question that could seems dumb. I am storing the formatting for a currency in the main Elm object. Now everytime someone wants to use CurrencyFormat needs to pass the main model. Is there a best practise to avoid passing the main model around ?

2019-02-14T04:32:33.281300

You don't have to pass the whole model to functions which need only currency format. Write functions accepting your CurrencyFormat record and pass only that field when calling them
|
2019-02-14T04:38:24.281400
|
Lynne

Something like:
```
displayCurrency : CurrencyFormat -> Float -> String
displayCurrency = ...

displayCurrency model.currencyFormat value
```

Well, it depends on your app structure. The point is you can structure it the way when you pass only relevant data to helper functions
|
2019-02-14T04:42:56.282900
|
Lynne

elmlang

You can't have global variables, so properly structuring your app is the only way to avoid passing the complete model everywhere

2019-02-14T04:44:09.283100
|
Lynne
|
elmlang

Unless your format is constant, of course. Then you can just have another module with function returning it

I understand that, and, I believe, it is not a super good practice to pass it everywhere as it complicates refactoring

there is a structure that goes by various names but in essence implies that there is a Context in which things happen. This context data is held in a record or some Custom Type and is passed around.

that's was really interesting! thanks! And I believe you can create multiple different sharedState based on the module you are in.

2019-02-14T05:02:59.287500

Anderson

so you only have the dependencies you need in the right place

I think the point of SharedState is that it is shared between all modules
|
2019-02-14T05:03:49.287900
|
Lynne
|
elmlang
|
general
|
So you should not need different shared states
|
2019-02-14T05:04:12.288100
|
Lynne
|
elmlang
|
general
|
Only if your app is split into groups of modules but that's most likely an overkill
|
2019-02-14T05:04:35.288300
|
Lynne
|
elmlang
|

|
Yes, the idea of the SharedState is that it acts like a context for all the places of the app. You can have partitions within this state that handle various aspects.

Howdy everyone!
I wanted to inspect the VirtualDom Kernel code because I am getting it to crash. I would like to make some modifications to it locally in order to fix it.
The problem is - I can not find the source code that actually gets compiled. I am using `elm/[email protected]`. In the chromium inspector it shows me the line that crashed to be right below
```
// tag must be 1 or 2 at this point
var vKids = vNode.e;```

But in the source code of virtualDominside `~/.elm/___/virtual-dom/1.0.2/` it says
```
// tag must be __2_NODE or __2_KEYED_NODE at this point
var vKids = vNode.__kids;
```
And when I try modifying this file it does not arrive in the browser when using elm-make.
