I am trying to get the Vuelidate custom validator provided by the docs to work with my Vutify
This is the line of code from the docs
const mustBeCool = (value) => value.indexOf('cool') >= 0
When I add it to my validators like so it doesnt seem to work
name: { required, minLength: minLength(4), mustBeCool }
Here is the CodePen

What am I missing?

Here's a simple example on the forgot password reset page of my app, I would want to bypass the server side and just have the password reset to succeed on click so I would write a test and use the custom test store like so:
const customStore = {
state() {
return {
Authentication: {
passwordResetSuccess: false,
},
};
},
mutations: {
SET_RESET_PASSWORD_SUCCESS(state) {
state.Authentication.passwordResetSuccess = true;
},
},
actions: {
forgotPasswordResetPassword() {
this.commit('SET_RESET_PASSWORD_SUCCESS');
},
},
};
Then I could include the custom store in my beforeEach() and it worked great. I've tried everything I can think of to get this to work with pinia, but it doesn't seem to work.
I'm using jest along with vue/test-utils.
I basically tried just creating the test pinia store, but I can't figure out how to get the component to use the custom test store.
const useCustomStore = defineStore('AuthenticationStore', {
state: () => ({
passwordResetSuccess: false,
}),
actions: {
forgotPasswordResetPassword() {
this.passwordResetSuccess = true;
},
},
});
const authenticationStore = useCustomStore();
I can't directly add it as a plugin because it can't find an active instance of pinia.
I went through this guide: https://pinia.vuejs.org/cookbook/testing.html#unit-testing-a-store
and I also tried using jest mock as described here: https://stackoverflow.com/a/71407557/4697639
But it still failed.
If anyone has any idea how to create a custom store that can be used by the component and actually hits the custom actions, I could really use some help figuring this out. Thank you!!
Tao mentioned in the comments that this isn't a good way to do unit tests. I will mark this as resolved and fix how I do the testing.
In Vue3 is there a way to pass properties to a route without the values showing in the url?
I defined the route like this:
{
path: '/someRoute',
name: 'someRoute',
component: () => import('#/app/pages/SomeRoute.vue'),
props: (route) => {
...route.params
}, // <-- I've seen this method in Vue2 but in Vue3 the route.params is just empty here
}
I call the route like this:
<router-link :to="{ name: 'someRoute', params: { message: 'Some Message' } }">Some link</router-link>
When I change path into path: '/someRoute/:message', the message come through just fine but I just want to pass the message without it showing up in the url.
I've seen a couple of Vue2 examples that use this method (e.g. https://stackoverflow.com/a/50507329/1572330) but apparently they don't work in Vue3 anymore.
Also all the examples in the Vue3 docs (https://github.com/vuejs/vue-router/blob/dev/examples/route-props/app.js / https://v3.router.vuejs.org/guide/essentials/passing-props.html) pass on their values through the url itself so I'm not sure if it's even possible anymore.
Any thoughts on this would be helpfull.
Finally I found something about this in the changelog: https://github.com/vuejs/router/blob/main/packages/router/CHANGELOG.md#414-2022-08-22
Apparently it's no longer possible to send properties via params without the showing in the url. But fortunately they give some alternative suggestions.
The one that worked best for my situation was to use state: { ... } instead:
<router-link :to="{ name: 'someRoute', force: true, state: { message: 'Some Message' } }">Some link</router-link>
Now in the code of the page I read the property from the history.sate and put the value in whatever property I need it.
In case the url/route itself doesn't change you need to have an update hook and use force: true
public created() {
this.message = window.history.state.message;
}
public updated() {
this.message = window.history.state.message;
}
PS history.state has some limitations so in other situations one of the other suggestions from the changelog might work better

the formatter method, may include async method, and may be use async and await，when i use, page render uncorrectly。Is there a solution?
Welcome to Stackoverflow. Please do not send code in images, as this is very inconvenient to answer. And please do not add links to external pages unless it is an official documentation.
Vue only binds variables which are defined in the data section.
So this should work:
export default {
data() {
return {
scope: {
data: {row: []}
but this will not bind the row records:
export default {
data() {
return {
scope: {} // does not work with scope.data.row
I just want to be able to call
{{ globalThing(0) }}
in templates, without needing to define globalThing in each .vue file.
I've tried all manner of plugin configurations (or mixins? not sure if Nuxt uses that terminology.), all to no avail. It seems no matter what I do, globalThing and this.globalThing remain undefined.
In some cases, I can even debug in Chrome and see this this.globalThing is indeed defined... but the code crashes anyway, which I find very hard to explain.
Here is one of my many attempts, this time using a plugin:
nuxt.config.js:
plugins: [
{
src: '~/plugins/global.js',
mode: 'client'
},
],
global.js:
import Vue from 'vue';
Vue.prototype.globalFunction = arg => {
console.log('arg', arg);
return arg;
};
and in the template in the .vue file:
<div>gloabal test {{globalFunction('toto')}}</div>
and... the result:
TypeError
_vm.globalFunction is not a function
Here's a different idea, using Vuex store.
store/index.js:
export const actions = {
globalThing(p) {
return p + ' test';
}
};
.vue file template:
test result: {{test('fafa')}}
.vue file script:
import { mapActions } from 'vuex';
export default {
methods: {
...mapActions({
test: 'globalThing'
}),
}
};
aaaaaaaaand the result is.........
test result: [object Promise]
OK, so at least the method exists this time. I would much prefer not to be forced to do this "import mapActions" dance etc. in each component... but if that's really the only way, whatever.
However, all I get is a Promise, since this call is async. When it completes, the promise does indeed contain the returned value, but that is of no use here, since I need it to be returned from the method.
EDIT
On the client, "this" is undefined, except that..... it isn't! That is to say,
console.log('this', this);
says "undefined", but Chrome's debugger claims that, right after this console log, "this" is exactly what it is supposed to be (the component instance), and so is this.$store!
I'm adding a screenshot here as proof, since I don't even believe my own eyes.
https://nuxtjs.org/guide/plugins/
Nuxt explain this in Inject in $root & context section.
you must inject your global methods to Vue instance and context.
for example we have a hello.js file.
in plugins/hello.js:
export default (context, inject) => {
const hello = (msg) => console.log(`Hello ${msg}!`)
// Inject $hello(msg) in Vue, context and store.
inject('hello', hello)
// For Nuxt <= 2.12, also add 👇
context.$hello = hello
}
and then add this file in nuxt.config.js:
export default {
plugins: ['~/plugins/hello.js']
}
Use Nuxt's inject to get the method available everywhere
export default ({ app }, inject) => {
inject('myInjectedFunction', (string) => console.log('That was easy!', string))
}
Make sure you access that function as $myInjectedFunction (note $)
Make sure you added it in nuxt.config.js plugins section
If all else fails, wrap the function in an object and inject object so you'd have something like $myWrapper.myFunction() in your templates - we use objects injected from plugins all over the place and it works (e.g. in v-if in template, so pretty sure it would work from {{ }} too).
for example, our analytics.js plugin looks more less:
import Vue from 'vue';
const analytics = {
setAnalyticsUsersData(store) {...}
...
}
//this is to help Webstorm with autocomplete
Vue.prototype.$analytics = analytics;
export default ({app}, inject) => {
inject('analytics', analytics);
}
Which is then called as $analytics.setAnalyticsUsersData(...)
P.S. Just noticed something. You have your plugin in client mode. If you're running in universal, you have to make sure that this plugin (and the function) is not used anywhere during SSR. If it's in template, it's likely it actually is used during SSR and thus is undefined. Change your plugin to run in both modes as well.
This would be the approach with Vuex and Nuxt:
// store/index.js
export const state = () => ({
globalThing: ''
})
export const mutations = {
setGlobalThing (state, value) {
state.globalThing = value
}
}
// .vue file script
export default {
created() {
this.$store.commit('setGlobalThing', 'hello')
},
};
// .vue file template
{{ this.$store.state.globalThing }}
I am using Vue (server side rendered) with mjml to generate emails.
So I have something (overly simplified) like:
<mjml><mj-body>Hello {{ User.Name }}</mj-body></mjml>
If the model doesn't define User then Vue throws an error and the whole output is lost.
What I want to the output to be along the lines:
<mjml><mj-body>Hello <error>'User' is undefined</error></mj-body></mjml>
I have implemented Vue.config.errorHandler but that just tells me about the error -- there is no rendered output.
Anyway to implement the equivalent of an error handler around each variable substitution?
If you are using Vue version >= 2.5, you can use errorCaptured to create an ErrorBoundary
const ErrorBoundary = {
name: 'ErrorBoundary',
data: () => ({
error: false,
msg: ''
}),
errorCaptured (err, vm, info) {
this.error = true
this.msg = `${err.stack}\n\nfound in ${info} of component`
},
render (h) {
return this.error
? h('pre', this.msg)
: this.$slots.default[0]
}
}
and use this in your component
<error-boundary>
<mjml><mj-body>Hello {{ User.Name }}</mj-body></mjml>
</error-boundary>
If the application has any javascript error, it will be displayed on UI
Example on codepen
If you want to have more user-friendly error, you can customize ErrorBoundary to have fallback to another component. You can find out in this tutorial
Another good example of using errorHandler
