QUESTION
Just starting out with Fable / Elmish / F#, but getting stuck getting a basic concept done...
The goal of the code is to execute a simple HTTP GET request and, thereafter, to post the results of the GET request to the user on a web page.
The idea was to use Fable Promise
or async
to execute the GET request and return the result, thereafter the result can be displayed on a web page using Elmish and Fable.
I expected that the web page (localhost) will output a text string containing the response of of the GET request, instead I only got "[object Promise]" on the web page. The desired response of the GET request is however logged on the Browser console. If I issue a printfn command with the txt
in the body of the promise (before the return
) I can also see the result of the GET request in the browser console.
Thus: I have no idea how to access the results of the promise. Please help, what am I missing? The sample apps from [Fable][1] , there is a image "container" created and an image placed based on the results of the HTTP get, but I need to work with text (json string).
Here is my code:

Use mkProgram because it gives you flexibility to specify Cmd callbacks

QUESTION
Sorry, but I'm a newbie with Fable and F#. I started a boilerplate from SAFE project, and I created a SPA with two pages. However, all the logic is inside a single file. My question is. How can I implement a router putting each view in one file?
I would something like that:
...ANSWER
Answered 2019-Mar-27 at 10:23in general, all the Elmish "components" (you can understand it as "file") have:
- a
Model
representing their state - a
Msg
representing the possible action supported in the component - an
update
function reacting to aMsg
and generating a newModel
from the previousModel
state - a
view
function to generate the view from the currentModel
state
In my application, I use the following structure which allows me to scale (indefinitely) the application.
A Router.fs
file responsible to handle to represents the different routes and the parsing
function.

I have the same code on the button1, but changing label1_DragDrop
to button1_DragDrop
How can I do this?

Answered 2019-Mar-23 at 14:03If you have the same error, I explain my answer:
You need to have an DragEnter
configured for the button you use.
Using the DragDrop isn't enough.
QUESTION
I am creating a Homebrew formula:
...ANSWER
Answered 2018-Dec-26 at 23:30This is a combination of two issues:
- There is an error in your formula.
- Homebrew's error reporting was accidentally broken three days ago.
So, Homebrew tries to report the error in your formula, but then runs into a bug in its own error reporting.
It seems that your SHA-256 checksum is not matching. Therefore, Homebrew tries to report the error, but then runs into this bug which was introduced three days before you wrote your question and was fixed three hours after.
To fix this,
- You need to fix the error in your formula (correct the SHA-256 checksum, or figure out why the checksum does not match the downloaded file)
- Wait until the bug is fixed and update Homebrew, to get proper error reporting back.

QUESTION
I am trying to upload a file using Fable-Elmish and the React Helpers. However, I can't work out how to convert the form event when a file is selected into something that I can send off to the server using Fetch. This is the view:
...ANSWER
Answered 2017-Apr-24 at 13:44Your going to need to create a new FormData object and append the file to it.
let formData = FormData.createNew
formData.append("file", file.[0])
Then change your call to postRecord to pass formData instead of file. You need fetch to encode it, but you are just passing the raw array of files.
At least that is my understanding from the fetch example on uploading a file. Also, post record looks wrong to me, is there just a "post" method you could use? postRecord implies it is expecting a record type.
QUESTION
So I downloaded this plugin https://github.com/vmitchell85/alfred-vuejs-docs and I got the Powerpack. Here is me trying to execute the workflow but pressing enter at this point does nothing:
After I press space and enter "vue events", I get in the debug:
[2018-09-02 16:56:33][ERROR: input.scriptfilter] Code 127: /bin/bash: php: command not found
Which is strange because I fire up my Terminal.app
(Which uses bash) and I do php -v
which gives me: PHP 7.2.8 (cli) (built: Jul 19 2018 12:15:24) ( NTS )
. Same thing on my zsh
profile.
What do I do?
...ANSWER
Answered 2018-Sep-09 at 17:05Look at the image you posted. There's a Script Filter object on the Alfred Editor. You just have to double-click on it and replace php vuejs.php "{query}"
with /usr/local/bin/php vuejs.php "{query}"
