QUESTION
I have a Nuxt ^2.15.8 application which is constantly reloading after I run yarn dev
.
The console will show a message like ↻ Updated 1647868577626
, and then the application is rebuilt, as if I just run yarn dev
. This happens constantly over and over, without me doing any changes in the code.
I googled a bit, and found applications like gitkraken might be modifying the content of the .git folder and that could trigger a reload.
So I keep gitkraken closed.
I also added these lines to my nuxt.config.js
file:
ANSWER
Answered 2022-Apr-03 at 10:40The actual issue was actually a version bump of ESlint from 1.x.x
to 3.x.x
. git bisect
helped finding out the actual culprit!
Cloning the repo again and reinstalling the dependencies again, fixed all the above mentioned issues while running yarn dev
!

I am attempting to deploy a vuejs app to github pages. I have followed every stackoverflow post, and every tutorial I have found online. No matter what I do, the page only displays the readme file.
I am using the gh-pages branch.

...ANSWER
Answered 2022-Mar-26 at 17:00You do not seem to have the files you build via vue in a folder that is served by GitHub Pages. Go to the repository settings in GitHub and choose "Pages". There you can switch the branch and the folder in the branch that should be served. Currently only "/" (root) or "/docs" are allowed. See the GitHub Pages Docs on this
For your use case, changing this to "/docs" and renaming your "dist" folder to "docs" after building your page / changing the output folder in your compiler should do the trick. Take note that it will take a few minutes for the new index.html to be served instead of the current Readme after changing this.
QUESTION
Migrating VueJS project from JavaScript + Options API to TypeScript + Composition API, I have gradually found equivalents of most of the stuff. One thing that I'm struggling with is the v-model
feature. I found a good article on implementing it using Composition API, where author creates a composable function that can be reused in components that want to implement v-model
. I'm trying to now write an equivalent function using TypeScript.
Here is the original JS code:

Answered 2021-Oct-22 at 16:26Just in case it helps someone down the road, it turned out that I was using wrong version of PropType

class should be imported like this:
QUESTION
When clicking in a select that lists items with really big integers as 738883988997898200
, the select options hang in the screen and we can't proceed.
We can't proceed because we are inside a v-form that's validating that field, which doesn't have a value. This is happening because the v-select is not able to v-model the bigint.
Does anyone faced this before? and have a tip on how to deal with it ?
Bellow we have both of the errors that it console logged in the screen as Errors
...ANSWER
Answered 2022-Mar-03 at 03:53One workaround is to convert the v-select
's items to strings before binding it. You could use Array.prototype.map
with the String
constructor as the argument:

QUESTION
Consider the following:
...ANSWER
Answered 2022-Jan-06 at 13:29The preferable method in modular environment (which Vue 3 setup is commonly is) is to just import api
in places where it's used, regardless of whether it's used inside or outside the component.
The solution with Vue global property originated at the time when Vue applications weren't necessarily modular so they relied on Vue instance as global application scope. Currently it's suitable only for properties that are primarily used in a template and require boilerplate code to import and expose them. The example is $t
in vue-i18n
.
The solution with provide
/inject
is usable for cases that need dependency injection. A common case is a library that require dependencies to be loosely coupled. Another one is that a dependency depends on component hierarchy and may vary between components.
The solution with window
should be avoided, unless application is divided into separate scripts that cannot interact through common JS modules. Even then the problem is that a script that defines global variable should be loaded before those that use it.

QUESTION
So I Have this loop of inputs(code below :)). So basically I'm trying to get every input in that loop by a unique ref like its explained in Vue3 documentations => Here
I have this Array inputs
where I'm saving all inputs like documentations suggest. what I want to achieve here is getting the last value. But I'm facing a strange issue that's why I'm here.
So when I try to console.log
the last value of that array I get the before last one not the last(I'll explain with image for more comprehension).and when I console.log
the inputs
array I can see that it contains the last value but I cant get it with all methods I tried:
ANSWER
Answered 2021-Dec-21 at 17:55I think the problem is, that there is no "re-render" between setting the data and trying to search it in the "ui"(inputs) list. Try to add await nextTick()
after your found.items.push
. Then vue can re-render and the v-for
will add the item to inputs
.
QUESTION
The app has been running successfully in production for a year, and works perfectly on MacOS localhost. Recently needed to set up the app to run on Windows 10 localhost, and after resolving all the errors, now the app boots up, requests seem to get through, however, only the '/' page actually renders, all the other routes don't render and stay at a blank page.
What could be a reason?
During initial setup, I ran into an issue with windows-build-tools and a missing Python, which I ended up eventually resolving by installing everything through Chocolatey. Could this be related?
Node version on Windows is newer than one specified in project, could this cause this?
I'm happy to provide more details and perform any experiments any of you recommend or suggest. My own guess is that it is either something related to setup on Windows or some issue with the packages on Windows.
The app is booted up through a package.json
start script:
ANSWER
Answered 2021-Dec-14 at 19:01Node version could be a problem. That windows-build-tools is required for the installation indicates there's binary dependency that is potentially incompatible with current Node version. Binary NPM dependencies usually provide a subset of precompiled binaries for a specific package version, where a combination of platform and Node.js version that can be considered safe or supported. For any other combination, binary package needs to be compiled for current platform with build tools. This doesn't always mean that the package is incompatible but this is common.
For example, node-sass
(doesn't seem to be used here) has different versions that correspond to specific Node.js versions and provides precompiled binaries for a supported subset; for unsupported Node.js version it falls back to compilation during installation process and most likely fails.
It's unknown which dependency causes this problem in this case, this needs to be reviewed in npm/yarn logs.
In order to avoid this situation, Node version could be matched with old one. Project dependencies need to be freshly installed because node_modules in use has been already tied to currently used Node version.
