QUESTION
I have the wackiest bug. Like....the wackiest! If any of ya'll want to put eyes on this, awesomesauce! I really appriciate it! I am creating a survey with REACT, Redux, SQL, HML, Material-ui, and CSS.
I've created a graph of information with am4charts using data from a database. Everything is working and will show up on the page......but not on page load. What I am seeing in my console is that the page will load, it fires off my get request but doesn't return with the data fast enough (I think). By the time that the get request loads, my graph has populated with no data.
Here is the code that I have for the page that I am rendering. What is really odd is that, once my code has run, I can cut a line of code (I've been using a console log). And then the graph will render and load.

QUESTION
So i have a 404 handler and a router file:
404 handler:
...ANSWER
Answered 2021-Jun-15 at 17:10Express regular request handlers are expected to have no more than 3 arguments as you can verify here.
And looking up Function.length
:
length is a property of a function object, and indicates how many arguments the function expects, i.e. the number of formal parameters. This number excludes the rest parameter and only includes parameters before the first one with a default value.
It becomes clear why the second function works and the first one doesn't:
QUESTION
I am building an app following the Rest Countries API challenge from frontendmentor (https://www.frontendmentor.io/challenges/rest-countries-api-with-color-theme-switcher-5cacc469fec04111f7b848ca). I have run into a problem. When clicking on the router link in countryDetail.js, the url changes but the component doesn't get re-rendered unless the page is refreshed.
CountryDetails.js
...ANSWER
Answered 2021-Jun-15 at 17:07The issue seems to be that you are already on the "/country/:name"
path and are clicking to visit another country. The router correctly updates the URL in the address bar, but because CountryDetail
is already mounted it neglects to recompute the item
and allCountries
state. This is because the useEffect
hook only runs once when the component mounts.
The name
param (match.params.name
) is actually a dependency for the GET requests, it should be added to the useEffect
hook's dependency array.

QUESTION
I have a route in the backend that I would like to call every X amount of time. Right now I am using ajax to make the call from a set interval function on the client side:
...ANSWER
Answered 2021-Jun-15 at 13:14You can make an internal call from the server itself, rather than from within a client. It would follow exactly the same logic (with the interval), but the code would be on the backend :)
Also if you'd like it a bit more well defined, you could use something like node-cron:

ANSWER

QUESTION
This code is incorrect. Redirect only redirects, I don't think you can pass results through it.
...ANSWER
Answered 2021-Jun-15 at 10:25There are some ways to pass the data to the new route.
you can render the submitted template file by passing data if you don't want to change the URI
If you want the specific URI you can pass the data as query params into your route you can see the example in the below https://stackoverflow.com/a/19038048/6551916
