QUESTION
React beginner here.
My code 👇
...ANSWER
Answered 2021-Jun-30 at 09:27When you change the state, the component is re-rendered, i.e. the function is executed again, but the useState
hook returns the updated counter this time. To use this updated value in your MouseTrap
, you must create a new handler (and remove the old one). To achieve this, simply remove the dependency array of your useEffect
call. It will then use the newly created triggerSomething
function.

Just ran into this error:
...ANSWER
Answered 2021-Apr-19 at 12:35Here's how I solved this problem:
First, what's happening: react-hook-mousetrap is looking for react@16.8.0, but it is not finding it. Instead it is finding @react17.0.1, which is a newer version. For some reason mousetrap doesn't like this newer version, and you are being notified (it is not a big deal, but they decided it was worth stopping your build).
One solution: forcibly install the specific version of react that mousetrap wants:
QUESTION
I am building a react app that allows the user to copy and paste text (from one input field to another) as well as copy list items within a list.
Now I want to support keyboard shortcuts for both use cases. I tried overriding the default behavior using MouseTrap (and also tried hotkeys) and that's working fine as long as I only copy text OR list items. But I haven't managed to support context aware copy paste. I want the copy command to copy list items when the list item is focused (or mouse cursor within the area of the list) and copy text when the list is not focused.
What makes things even worse: I have pages where there is no item list, so there I just want to have the default copy paste text behaviour.
I have tried following:
- hook up hotkeys in the componentDidMount of the App component
- hook up hotkeys in the componentDidMount of the ListView component
When I press ctrl+c BOTH components fire the event, and even if I return false (which should stop the event from bubbling), it fires in both of them. What am I doing wrong?
...ANSWER
Answered 2021-Mar-15 at 11:33Let's split your problem into parts.
- You want copy to work as intended in all general cases
- You want to override default behavior and if list is focused - copy list items
- You want to override default behavior and if list item is focused - copy focused item
Text input behavior that you describe is generic and unless you want to modify it somehow I leave it out.
Assuming that your elements already focusable (have tabIndex
attribute), you have for each item and for whole list this states: "focused" and "not focused". To detect change from one state to another you can use event listeners that handle "blur" and "focus" events. There is a catch that event from item will bubble up to list, so, in my example I use only listeners on list. You might want more fine grained event listeners attachment (you can even transform it into HOC).
Another thing you will have to handle is how you intend to store copied and pasted information. If you will store it in state as I did in example, user will loose ability to copy something and paste outside of your application. Also, in my example I couple copy and paste, so you will be able to paste only when you focused one of the elements. You probably want paste to work universally. You can use Clipboard API or deprecated execCommand for this.
And finally, since I use Windows, cmd
don't work, so I changed it to ctrl
.
Now, to example:

Beginner here. Trying out Next.js but I'm struggling with the following. Just tried to install react-hook-mousetrap
and imported it like I normally would:
ANSWER
Answered 2021-Feb-20 at 20:19The error occurs because react-hook-mousetrap
is exported as an ESM library. You can have Next.js transpile it using next-transpile-modules
in your next.config.js
.

QUESTION
when I try to run bundle install , I got the following error:
...ANSWER
Answered 2020-Oct-13 at 11:37Try updating your Gemfile
to use json@1.8.2
instead of 1.8.1
- according to this thread Ruby 2.2.x is incompatible with json 1.8.1
.
1.8.2
should be functionally similar and not affect any of your other dependencies.
You can also run bundle update json
to let bundler try to fix it for you - but that may put you at a much later version than 1.8.2
, I'm not sure.
No harm in trying a couple things and reverting your changes.

...ANSWER
Answered 2020-Aug-15 at 09:55Finally I found solution to this issue.Here we are trying to use Personal access token(PAT).In order to use PAT for authentication we have to use authorization as "Basic"
instead of "Bearer"
.More over instead of adding PAT alone to the Request header we have to use combination of username and PAT.Say base-64-encoded-string of username:PAT.

QUESTION
We are receiving this build warning in Angular 10. How can this be fixed? Is there an alternative NPM like Lodash-es ?
hotkeys.js depends on 'mousetrap'. CommonJs and AMD Dependencies can cause optimization bailouts
Resource: Upgrading to Angular 10 - Fix CommonJS or AMD dependencies can cause optimization bailouts
...ANSWER
Answered 2020-Aug-10 at 13:50This can be fixed by you, if you prefer to contribute to the hotkeys
module, by making it ECMAScript compatible.
Or you can just add the module to allowedCommonJsDependencies
in your angular.json
file as it shown on official documentation.
