QUESTION
I'd like to set the component's prop when the variable's value defined. Below is my current code.
...ANSWER
Answered 2021-May-27 at 04:05This explains your error message
Type 'null | undefined' is not assignable to type 'string | undefined'.
Cropper
's image prop expects a string
or undefined
but you are passing null
or undefined
Did you initialise coverFile
as null
? If so, you can set it to undefined
to silence the error
Update: If you can't figure out where the null is coming from you can simply do this:
QUESTION
I have an application that allows the user to upload photos, to edit them (crop, zoom and rotate) and to download.
I'm trying to add a preview mode, so the user can see how the file he's downloading will look like.
What I did works fine except for one thing - when the user clicks on the Clear Preview
button the photos go back to their original state (the state is being reset on Clear Preview
button click),
without keeping the changes the user made to them.
Any idea what am I missing and how to prevent the state reset?

.
I try to explain better: lets say you have this image in preview mode and user zooms it. So now original image is modified. Then, user clicks Clear Preview
button. Just before call setIsPreviewMode(false)
you could store modified image using, for example, dom-to-image. Something like:

I am seeing this issue 100% of the attempts at building webpack for production.
I've tried the approach mentioned on the other similar StackOverflow issues which is NODE_OPTIONS=--max_old_space_size=8192
my build command is:
...ANSWER
Answered 2020-Jul-30 at 14:16If your build takes longer than 10m without output this will happen.
You can use travis_wait
to print something to the console each minute, as per the docs: https://docs.travis-ci.com/user/common-build-problems/#build-times-out-because-no-output-was-received
Just travis_wait {your_command}
and you should be good to go.
Be aware that your build taking longer than 10m could be a indicator of a more complicated underlying problem/freeze.
QUESTION
I am working on ReactJs in which i am trying to use third party api. As i tested the api in postman, all the api's are working fine. But when i integrated the api in my project i am getting CORS error. I have searched on the google. I found the solution that use Proxy server. I tried using proxy server but still not working for me. May be I did not implement it correctly. I referred these links :
https://daveceddia.com/access-control-allow-origin-cors-errors-in-react-express/
https://levelup.gitconnected.com/overview-of-proxy-server-and-how-we-use-them-in-react-bf67c062b929
DO i need to install anything? Any help is appreciated.
package.json
...ANSWER
Answered 2020-Apr-02 at 19:08If you want a way to do this for development purposes (as some apis don't allow adding localhost or http to allow origin) you can use cors disabled mode of the browsers like for chrome
google-chrome --disable-web-security
does the trick OR in windows you can create a shortcut (rightclick > send to desktop ) and in its properties(right-click > properties) add the flag --disable-web-security
after ***/chrome.exe (you will see a textbox).
If you want a solution for production, there is no other way than configuring the api for your website. You can follow the link provided by Dominic to learn more about cors. All the third pary API uses allow any origin header or atleast give a way to configure cors in console.

Answered 2019-May-23 at 14:19If I understand you correctly, you want to display a preview image. If so, you can use a canvas
to manipulate the original image and cut and re-posisioning it.
