Vue 3: How to efficiently update a large list with dynamic filtering while maintaining performance?
I'm testing a new approach and I'm trying to debug I'm trying to configure I'm learning this framework and I'm working on a Vue 3 application where users can filter a large list of items based on multiple criteria... The list can contain over 10,000 items, and I'm using `v-for` to render them. I noticed that as the filtering criteria change, the performance significantly drops, and the UI becomes unresponsive while updating. Currently, I have a computed property that filters the list based on user input: ```javascript computed: { filteredItems() { return this.items.filter(item => { return item.name.includes(this.searchText) && item.category === this.selectedCategory; }); } }, ``` This works fine for smaller datasets, but with larger arrays, it's causing noticeable lag. I've also tried debouncing the input for `searchText`, but it doesn't seem to resolve the performance issues. My current template looks like this: ```html <template> <input v-model="searchText" placeholder="Search items..." /> <select v-model="selectedCategory"> <option value="">All</option> <option v-for="category in categories" :key="category" :value="category">{{ category }}</option> </select> <ul> <li v-for="item in filteredItems" :key="item.id">{{ item.name }}</li> </ul> </template> ``` I also tried using `v-if` to conditionally render the list based on whether there are any items after filtering, but that didn’t help. I received a warning about inefficient rendering when the list size grows. Could someone suggest a more efficient way to handle this scenario? Maybe using a watcher or a different approach altogether? Any insights would be greatly appreciated! What's the best practice here? Thanks for any help you can provide! I'd really appreciate any guidance on this. This is happening in both development and production on macOS.
