QUESTION
I have spent some hours playing with Electron and I have observed that it consistently takes more than 2.5 seconds to draw a trivial html file to the screen. The timeline is roughly as follows:
- 60 ms: app
ready
event is triggered; we create a window usingnew BrowserWindow()
- 170 ms: a blank window appears on the screen
- 2800 ms: the window shows the specified HTML
I have set up a repository with my code, which is derived from Electron's quick start docs.
Regarding my machine, I am running Windows 10 on a ThinkPad T460 from 2016 with a SSD and enough memory.
QuestionsShipping an application that shows a blank window for so long upon startup is a no-go for me. I assume most people developing Electron apps think similarly. Hence my first question: am I doing something wrong? Or is this the expected loading time for a trivial Electron app?
Assuming this is normal behavior, what is the common way to deal with this problem? Some ideas come to mind:
- Asking Electron to show a splash screen: unless there is specific built-in functionality for this, it seems like a no-go, since the splash screen itself would be shown only after 2.5 seconds.
- Hide the app's window until it is rendered (using the
ready-to-show
event), so no blank window is shown. This isn't ideal, since it means that the user doesn't get any feedback whatsoever that the application is actually loading. - Create a wrapper application (using native code) that displays a splash screen, launches electron and hides itself once the electron window is shown. Kind of defeats the purpose of using Electron in the first place, because you end up writing native code and adding accidental complexity.
- Setting the background color of the window to something resembling your app, as suggested by the docs. This just doesn't look very well.
Given this must be a common problem, I hope standard solutions have been found by the community. I'd be glad if someone can point me in the right direction.

Answered 2021-Jun-14 at 02:38What if you hid your window until it's ready to show, then show your window, and while your window's hidden show a loading spinner.
First only show your main window until after it's ready:

ANSWER
Answered 2021-Jun-10 at 14:39Electron uses MacOS local frameworks, that weirdly enough, you don't seem to have on your computer.
Try to list your frameworks to confirm this: ls -al /System/Library/Frameworks/
If you don't have any, or miss some of them (depending on your OS version), chances are you won't be able to build anything native at all, and your system should be all broken by now (plus, CoreFoundation is the most important framework): a clean install of the latest XCode won't install those frameworks back AFAIK.
Then, your options are:
- reinstall macOS
- get those framework from another mac using the same macOS version
- grab them from your recovery

I have used Admob in several projects already, but this time I encounter a strange problem.
I followed all instructions from the official documentary (here), and everything basically works, at least the test ads.
But I've encountered the problem, that some classes just can't be imported.
For example, when I take this code from the documentation:

QUESTION
I used to code in R, but have recently switched back to Python. For a research project about hate speech, I like to display and store messages from Telegram channels with telethon in a dataframe. I need to store the data because I want to visualise and analyse it computationally. I am used to pandas dataframes, but happy with other alternatives too. I am using Python 3.7 with Spyder IDE.
With this tutorial I can get and display the messages within a channel I am a member of.
...ANSWER
Answered 2021-Jun-08 at 11:51Your question is more about Python and Pandas than Telegram and Telethon, as far as I can understand.

i searched for it and i think i am Breaking the Rules of Hooks but which one i dont know .. can u help me with solving it too? the Home function was working correct when i followed react router (https://reactrouter.com/web/guides/quick-start/1st-example-basic-routing) i just replaced it with this home function and it worked successfully
now what i want to do is to request data from the server and receive it in react js so i can display it successfully
EDIT: every thing is working Fine at express as a back end server
...ANSWER
Answered 2021-Jun-05 at 22:49inside of the componentDidMount
function of a class component, you are manually calling a function component (Home()
) instead of attempting to render it with JSX (or React.createElement
). manually calling a functional component which uses hooks is a violation of the rules of hooks, just like the error message says.
you need to reference your functional component inside the JSX returned by your class component's render
method (or the JSX returned by another functional component).

I've built a Django API that uses django-graphql-auth and django-graphql-jwt packages to implement authentication. I followed the package's documentation and got everything to work and everything is working from my Angular UI. The only issue is that even requests made from Postman without the Authorization header, are able to fetch the data from the graphql API.
This is my Django project's settings.py

I made a project called trydjango where I can access products I created with the products/ [name='product']
link, but somehow it isnt working and I cant find the error.
When i open http://127.0.0.1:8000/products/1/

ANSWER
Answered 2021-May-26 at 13:34Your url pattern is: products/
and the requested url is products/1/
. What's the difference here? Well the requested url ends with a trailing slash (/
), while the pattern does not.
Even if you made a request to products/1
you would still be redirected to the url with the trailing slash as Django by default redirects all urls without a trailing slash to the same url with a trailing slash appended. Hence simply change the pattern to have a trailing slash:
