I'm trying to change the links based on the variable user_role which is stored in Vuex(store). I'm not able to find an appropriate way to track the change and based on its value I want to perform some method. Any suggestions on how to do it?
------------------------------store.js-------------------------------
export default new Vuex.Store({
state: {
user_role: "User"
},
mutations: {},
actions: {},
modules: {}
});
-----------------------------------component.vue---------------------------
export default {
name: "Navbar",
data() {
return {
links: [
{ text: "Projects", route: "/projects" },
{ text: "Requests", route: "/requests" },
{ text: "", route: "" },
{ text: "Resources", route: "/resources" }
],
pers_actions: ["Profile", "LogOut"],
};
},
watch: {
user_role: {
if (user_role === "PM") {
this.links[2] = {
text: "Allocations",
route: "/allocations"
};
} else if (user_role === "PMO") {
this.links[2] = {
text: "Reports",
route: "/reports"
};
} else if (user_role === "User") {
this.links = [
{
text: "Allocations",
route: "/allocations"
}
];
}
}
},
Rather than explicitly mutating your local data in response to some state change, it is better to compute your links within a computed property because it will automatically update whenever some dependent data has changed. It'll "just work".
computed: {
links() {
switch (this.$store.state.user_role) {
case: "PM": return [
{ text: "Projects", route: "/projects" },
{ text: "Requests", route: "/requests" },
{ text: "Allocations", route: "/allocations" },
{ text: "Resources", route: "/resources" },
];
case: "PMO": return [
{ text: "Projects", route: "/projects" },
{ text: "Requests", route: "/requests" },
{ text: "Reports", route: "/reports" },
{ text: "Resources", route: "/resources" },
];
// For any other role
default: return [
{ text: "Allocations", route: "/allocations" },
];
}
}
}

I want give an element a class when it's in the viewport and I don't know how I can handle it. I watched a few Videos on Youtube but nothing helped me.
I work with a boilerplate so I can't implement additional plugins.
My script looks actually like this.
export default {
head() {
return {
title: this.$t("headData.index.title"),
meta: [
{
hid: "description",
name: "description",
content: this.$t("headData.index.description")
}
]
}
},
data() {
return {
debugSingleScroll: true,
}
},
methods: {
handleScroll() {
if(this.debugSingleScroll) {
this.scrollToNextModule()
this.scrollToLastModule()
this.debugSingleScroll = false;
}
},
scrollToNextModule() {
this.$refs.factsModule.triggerAnimation();
},
scrollToLastModule() {
},
},
mounted () {
window.addEventListener('scroll', this.handleScroll);
},
destroyed () {
window.removeEventListener('scroll', this.handleScroll);
},
}
in a normal way with out translation but i want to translate the two object array and bind into a component
<InfoNews
v-for="infonew in infonews"
:id="infonew.id"
:title="infonew.title"
:content="infonew.content"
/>
data() {
return {
infonews: [
{
id: "01",
title: "what we do",
content:"industke aecimen book. ",
},
{
id: "02",
title: "our mission",
content:"ggdddg",
},
],
};
Make infonews a computed property. The title and content of each should be the translation keys.
export default {
computed: {
infonews() {
return [
{
id: "01",
title: this.$t("what we do"),
content: this.$t("industke aecimen book"),
},
{
id: "02",
title: this.$t("our mission"),
content: this.$t("ggdddg"),
},
]
};
}
}
I'm trying to create xstate Machine which has condition to be check when moving to another state(Using VueJs).
issue is the way tried which is not working with vue-kanban(https://github.com/BrockReece/vue-kanban) pkg
below is my sample state machine config :
stateMachineConfig: {
id: "kanban",
initial: "on-hold",
states: {
"on-hold": {
on: {
IN_PROGRESS:"in-progress",
}
},
"in-progress": {
on: {
RELINQUISH_TASK: "on-hold",
PUSH_TO_QA: "needs-review",
},
},
"needs-review": {
on: {
REQUEST_CHANGE: "in-progress",
PASS_QA: "approved",
},
},
approved: {
type: "final",
},
},
},
this is the UI of kanban(https://ibb.co/6rWxN0F)
after i changing above config by adding condition to "on-hold" state then i can't move to anywhere from "on-hold" state.
below is the new config:
const searchValid = (context) => {
console.log(`context.status `, context);
return true;
};
stateMachineConfig: {
id: "kanban",
initial: "on-hold",
states: {
"on-hold": {
on: {
PICK_UP: [
{
target: "in-progress",
cond: searchValid
}
]
}
},
"in-progress": {
on: {
RELINQUISH_TASK: "on-hold",
PUSH_TO_QA: "needs-review",
},
},
"needs-review": {
on: {
REQUEST_CHANGE: "in-progress",
PASS_QA: "approved",
},
},
approved: {
type: "final",
},
},
},
any help to fix it!
I have tested your machine using the XState visualizer and all works properly, you can check it here
I am new to XState.js.
I want to use a simple ID in my context. How do I update the context using machine.send()?
const fetchMachine = Machine(
{
id: 'test',
initial: 'init',
context: {
id: '',
},
states: {
init: {
on: {
LOGIN: 'fetch',
},
},
fetch: {
on: {
LOGOUT: 'init',
},
},
}
})
const machine = interpret(fetchMachine).start()
How do I pass an ID to the context?
This does NOT do the trick:
machine.send({ type: 'LOGIN', id })
You have to use the assign action to update the context. I've updated your example to the following:
import { Machine, assign } from 'xstate';
// Action to assign the context id
const assignId = assign({
id: (context, event) => event.id
});
export const testMachine = Machine(
{
id: 'test',
initial: 'init',
context: {
id: '',
},
states: {
init: {
on: {
LOGIN: {
target: 'fetch',
actions: [
assignId
]
}
},
},
fetch: {
on: {
LOGOUT: 'init',
},
},
}
},
{
actions: { assignId }
}
);
Now once you call the following:
import { testMachine } from './machines';
const testService = interpret(testMachine).start();
testService.send({type: 'LOGIN', id: 'test' });
//or testService.send('LOGIN', { id: 'test'});
the action assignId will assign data from the event to your context
The value of this.$store.state.Auth.loginToken is modified by one of its child components. The initial value of this.$store.state.Auth.loginToken is undefined. But still, the update in its value has no effect in the cached value of navItems thus it always returns the second value.
computed: {
navItems () {
return this.$store.state.Auth.loginToken != undefined ?
this.items.concat([
{ icon: 'add', title: 'Add new journal entry', to: '/' },
{ icon: 'power_settings_new', title: 'Logout', to: '/logout'}
]) :
this.items.concat([
{ icon: 'play_arrow', title: 'Login', to: '/login' }
])
}
}
Is there a better way to keep a watch on this.$store.state.Auth.loginToken so that it can be used same as navItems?
I created a basic example of how you can use vuex getters and Auth token (codepen):
const mapGetters = Vuex.mapGetters;
var store = new Vuex.Store({
state: {
Auth: {
loginToken: ''
},
menuItems: [
{ icon: 'home', title: 'Home', to: '/' },
{ icon: 'about', title: 'About', to: '/about' },
{ icon: 'contact', title: 'Contact', to: '/contact' }
]
},
mutations: {
SET_LOGIN_TOKEN(state, data) {
state.Auth.loginToken = 1
}
},
getters: {
menuItems(state, getters) {
if(state.Auth.loginToken !== '') {
return state.menuItems.concat([{
icon: 'profile', title: 'Profile', to: '/profile'
}])
}
return state.menuItems
},
loggedIn(state) {
return state.Auth.loginToken !== ''
}
},
actions: {
doLogin({commit}) {
commit('SET_LOGIN_TOKEN', 1)
}
}
});
new Vue({
el: '#app',
store,
data: function() {
return {
newTodoText: "",
doneFilter: false
}
},
methods: {
login() {
this.$store.dispatch('doLogin')
}
},
computed: {
...mapGetters(['menuItems', 'loggedIn'])
}
})
This is just an example so you can ignore the actual login action. Also, the store should be a directory, the getters, mutations and actions should have their own files which are then imported in the index.js in the store like in this example
