QUESTION
We have an Express server in Node, on one route we upload a file and as a follow on need to send this file onwards to another end point for processing, which is not accessible to the initial client. Most use cases seem to depend on getting a path from the local server, but in our case the file doesn't exist on the local server, and we have it as an uploaded object.
I've tried using multer and also with file-upload package, but run into issues with both of them on trying to do the follow on upload to the 3rd party API. Both post to the 3rd Party API which then fails. However if I upload a file locally using fs from the Express server then it gets uploaded to the API fine.
I could therefore save it locally first, and then use the local file to send on and remove it, but that feels like it shouldn't be necessary.
The code using Multer, which puts the file onto req.file:
...ANSWER
Answered 2021-Jun-04 at 18:46I see two things:
You're constructing the form but eventually you're sending the file, not the form. Change your code to:
await axiosInst.post(url, form)When appending a file to a form in Node.js, you have to use the 3rd argument (file name). With multer as example, you would do:
form.append('file', fileBuffer, req.file.originalname);
I wrote an article on how to Send a File With Axios in Node.js. It covers a few commong pitfalls to avoid and I think you'll learn something useful.
QUESTION
i am trying my hand at front end development for the first time and am having a little glitch which is not behaving as i thought it would.
The website is calculating ratings for sports teams using ELO derived algos.
Problem 1 : On the EPL Game Results tab it should only have 'ternary algorithm' active on page load, and the tab should have a green underline. Currently nothing is underlined on initial load, and both tabs (ternary and MOV) appear to be active.
Problem 2 : when you click MOV algorithm, and then refresh the page, I need it to just be the MOV algorithm active and underlined. Currently, MOV stays underlined but both MOV and Ternary become active.
Here is the jsfiddle: https://jsfiddle.net/wa7gb43j/
...ANSWER
Answered 2021-Jun-05 at 03:59First of all, you have too much inline code going on, this is a bad practice. Avoid using inline style when possible. So instead of changing style.display, add/remove a class or an attribute that would do the style changes within CSS, this way you can eliminate the need of loop through elements to change all their styles.
Just a quick and dirty example of what I mean:

I am working on a Laravel application that requires user registration and login.
Alter registration, a user should have the possibility to add more info to his/her profile.
For this purpose, I did the following:
In routes/web.php I have the necessary routes, including update:
ANSWER
Answered 2021-May-30 at 16:56The route() function accepts a name, not a URL: https://laravel.com/docs/8.x/routing#generating-urls-to-named-routes
So you should have used route('update'). Though seeing your code, you might not realize the ->name() method should accept a unique route name. So you should make sure you don't have any other route named 'update'.
Some people do this: ->name('dashboard.profile.update'). You can see if you like this convention.
QUESTION
I've started getting this error from my Blazor WebAssembly app:
"Cannot read property '_blazorFilesById' of null error" with Blazor app
I'm assuming that's related to the InputFile component I'm using, which has been working fine.
I've tried restarting VS, clean & rebuilding, restarting IIS and killing Chrome all to no avail. What could be causing this?
...ANSWER
Answered 2021-Jan-30 at 22:40This turns out to be because I'd added conditional code to hide the InputFile component on the page. Doing that will cause the error as explained in this post on GitHub by BtbN:
Did you modify your page, so the InputFile element is not rendered anymore? It has to stay present, otherwise the browser cleans up any resources associated with it.
