QUESTION
I have an NPM package I am working on which has a dependency of react
. I then have a test app which has react
installed as a dependency. When I import my npm package into the test app, I get the following error:
Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:
- You might have mismatching versions of React and the renderer (such as React DOM)
- You might be breaking the Rules of Hooks
- You might have more than one copy of React in the same app
Running npm ls react
in my test app suggests I might have a duplicate of react

Answered 2021-Nov-15 at 01:42gulp-imagemin 8.0.0 and above are now ESM only. You can downgrade gulp-imagemin to 7.1.0 which is commonjs and it should work fine.

I'm running into an error on Windows 10 whenever I try to run webpack, it works fine on macOS. This is the error
[webpack-cli] HookWebpackError: Not supported
It runs fine without "CopyPlugin", but I would like to copy img folder into dist folder. Have you experienced similar issues and how did you fix them?

Or the latest
npm install node@latest -g
Under Windows npm install node
may note work, and you should install the latest from https://nodejs.org/en/download/ using Windows Installer (.msi)

After upgrading react-scripts to v5, craco start

's Github readme, states that it is supporting Create React App (CRA) 4.*
. By this statement, I'm assuming CRA 5
is not officially supported by craco
.
However, this repository utilizes both CRA 5
and craco
(but I have not verified that it is working). Use this repository to compare your setup (after verifying that the linked repositry is working), and try different settings/configs to see if you get further.
QUESTION
I would like to create a graph of the proportion of total memory consumed by each of the following for a given instance
:
node_memory_MemFree_bytes{instance="$instance"}
node_memory_MemAvailable_bytes{instance="$instance"}
node_memory_Buffers_bytes{instance="$instance"}
node_memory_Cached_bytes{instance="$instance"}
I know I can create a single graph from 4 separate queries where each metric is divided by node_memory_MemTotal_bytes{instance="$instance"}
:
- Query A:
node_memory_MemFree_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
- Query B:
node_memory_MemAvailable_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
- Query C:
node_memory_Buffers_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
- Query D:
node_memory_Cached_bytes{instance="$instance"} / node_memory_MemTotal_bytes{instance="$instance"}
I feel like there should be a terser way of doing this with group_left
since the right hand side is the same for each query and the left hand side can be reduced to a single query:
- Left:
{__name__=~"node_memory_(MemFree|MemAvailable|Buffers|Cached)_bytes",instance="$instance"}
- Right:
node_memory_MemTotal_bytes{instance="$instance"}
If I understand the "Operators" docs and this blog post correctly, I should be able to use group_left
to do this in a single query. However, I've been unable to do so.
I reason that since the left and right side of the equation have exactly the same labels excluding __name__
, I shouldn't need to use ignoring
or on
for the group_left
operator:
ANSWER
Answered 2022-Jan-16 at 08:39PromQL strips metric names before matching time series on the left and right side of binary operator such as /
- see these docs. In your case time series on the left side differ only by metric names, so PromQL sees series with identical sets of labels on the left side. The solution is to copy metric names for left-hand side time series into another label before applying the /
operator and then ignoring this label during the /
operation. This can be done with label_join or label_replace functions:
QUESTION
I'm working in a reacjs based app and i wanted to add firebase to store simple data, so i followed some firebase tutorials because i wasn't familiar with it. However, when i tried my code after setting up firebase i got like 43 different errors in my console. Now i managed to get rid of most of them (problems with polyfill) but i can't get around the last of them.
I get this errors, it seems that the problem has to do with worker_threads but i don't know where they came from and how to solve it, i saw some tutorials on node workers but i still don't understand what kind of data i have to pass or how to set it up.
...ANSWER
Answered 2022-Jan-05 at 21:26I couldn't find the solution to that specific error, however, i realized that Firebase updated to version 9 a few months ago and the usage had changed a lot compared to the last version. So if anyone else is struggling with these kind of errors please find the most recents tutorials on firebase 9.

QUESTION
So i'm new in JS and i have a task for mastering Ajax Requests.I should send an email input from form to the server and a lot more,but i can not figure out how to send this data to a server that is in another folder.I lost all my nerves with this task and i dont know what to do.
So,i have a folder personal-website-server and another folder src where is my project,both folders are in another folder,the parent.
It looks like this :
./
dist < webpack bundle folder
node_modules
personal-website-server
/ package.json in personal-website-server
src
and package.json in the parent folder
Image for more understanding:
So,i should do this:
Upon clicking on the "Subscribe" button, implement the functionality for sending a user email to the server. For that, make POST Ajax request using http://localhost:3000/subscribe endpoint. The call to the server should only be made when the form is valid (the validate function )
The connection is made through a proxy to the server,idk how this thing works and i get it hard to do this task because its not so described.
Codes:
I created fetch.js in src that checks if email is valid and sends it to the server,like i understood:
