Vue 3: How to handle dynamic class binding with computed properties for conditional styling?
I'm stuck trying to I'm stuck on something that should probably be simple... I'm working on a Vue 3 application where I need to dynamically apply different classes to a component based on certain conditions, but I'm encountering issues with class binding. I have a component that should change its styling based on a prop called `status`, which can be 'active', 'inactive', or 'pending'. I've tried using computed properties to manage the class names, but it seems that the classes don't update correctly when the `status` prop changes. Here's a snippet of my component: ```vue <template> <div :class="computedClass"> Status: {{ status }} </div> </template> <script> export default { props: { status: { type: String, required: true } }, computed: { computedClass() { return { 'bg-green': this.status === 'active', 'bg-gray': this.status === 'inactive', 'bg-yellow': this.status === 'pending' }; } } }; </script> ``` In my main file, I use the component like this: ```vue <StatusIndicator :status="currentStatus" /> ``` And in my script, I change `currentStatus` at various points: ```javascript methods: { updateStatus(newStatus) { this.currentStatus = newStatus; } } ``` Despite this setup, when I change the `currentStatus`, the classes don't update as expected. I see the correct output in the `<div>`, but the class bindings seem to lag behind, leading to incorrect styles being displayed. Sometimes there's also a console warning about "[Vue warn]: Avoid mutating a prop directly.", which I've traced back to how I'm updating the state. Could this be an issue with reactivity or something else? How can I fix the dynamic class binding to reflect the updates immediately? I'm working on a web app that needs to handle this. I'd really appreciate any guidance on this. Is there a better approach?
