<@Wendell> I would do it from the server side rather than on the front end, to do it on the frontend you’d need to give the client side credentials to hit the database and they wouldn’t be secret there
2019-04-17T16:09:54.360700
Alicia
elmlang

it is likely CORS preventing it, you have to use `withCredentials` to pass them <https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials> And the server you are connecting to has to return an `Access-Control-Allow-Credentials` header saying that it is OK

Wendell

I’m not familiar with doing it in serverless, but I’m sure something similar to what you can do on AWS is possible, there you’d have an API gateway with some routes set up to call your lambda function, and then the lambda function could run the actual query

Is there a simple way to xor two strings together? I notice that I can convert them to bytes using `elm/bytes`, but then there are no available functions for operations on those bytes
2019-04-17T17:29:11.365000
Isaiah
elmlang

This problem _seems_ simpler than it is. There are multiple ways to represent the same string in bytes - utf8, utf-16, utf-32, ...
2019-04-17T17:34:56.365100
Huong
elmlang
general
so you have to pick a binary representation, and then xor. Then there's the issue that the result may no longer be a valid representation of a string
2019-04-17T17:35:34.365300
Huong
elmlang
general
So what I'd probably do, is, use something like <https://package.elm-lang.org/packages/zwilias/elm-utf-tools/latest>, pick a representation, turn both strings into the same type of bytes, `List.map2 Bitwise.xor` them, and finally try to turn the result into a string again

Is there any way in Elm to detect if on focusout the entire container loses focus? You get this event for child nodes as well if you navigate between child nodes for example. But I would like to know when the entire container loses "focus". In JavaScript people seem to do that by checking if the document.activeElement ...
2019-04-18T03:27:55.373400
Erlene
elmlang

Write an event handler for focusout that stops propagation?
2019-04-18T03:31:42.373800
Earnest
elmlang
general
<@Earnest> the focusout fires only once.
2019-04-18T03:32:05.374200
Erlene
elmlang
general
But if you set it on a container it seems it is also set on the children.
2019-04-18T03:32:25.374500
Erlene
elmlang
general
So when one of the children loses focus, it fires too.
2019-04-18T03:32:41.375000
Erlene
elmlang
general
At the moment I can't seem to distinguish between the case where the focus moves between children, or away from the container.
2019-04-18T03:33:04.375500
Erlene
elmlang

So it's still called on the parent if you stop propagation from the children?
2019-04-18T03:34:04.375900
Earnest

Html events bubble by default, the event object has a `target` field that is the *specific* element that fired the event. In javascript I might do something like: `e.target.matches(‘#myParentNode’)` or `e.target === e.currentTarget`. The second solution should be doable in Elm no problem.
2019-04-18T03:36:41.379100
Danika
elmlang
general
<@Earnest> haven't tried this exactly, but the child has the blur element which does not bubble. Exactly what I need. But there's only one focusout event, not one for the child and then one for the parent.
2019-04-18T03:40:35.380500
Erlene
elmlang
general
<@Danika> the target is always the child node.
2019-04-18T03:40:49.380800
Erlene
elmlang
general
The child node has tabindex="0", so it has focus. If I tab out, the focusout event fires with target this child node.
2019-04-18T03:41:14.381500
Erlene
elmlang
general
But the currentTarget is your parent node, they aren’t the same.
2019-04-18T03:41:53.382300
Danika
elmlang
general
<@Danika> true, but that doesn't help me. If I move between child nodes currentTarget is still the container element.
