Vue v-for changing from version 1 to version 2 - vue.js

Question

I'm learning Vue.js and found this fiddle that does exactly what I want to do.
Here is the fiddle: https://jsfiddle.net/os7hp1cy/48/
I integrated this and am getting this error:
invalid expression: v-for="user in users | filterBy searchKey | paginate"
So I've done some digging and I see it has changed from version 1 to 2. However, I don't know how to fix this.
<li v-for="user in users | filterBy searchKey | paginate">{{ user.name }}</li>
I would like to replace this with something that Vue 2 will support and will work the same way.

As of Vue version 2, filters can only be used inside text interpolations ({{ }} tags). See the documentation for migrating from Vue version 1.
You can use a computed property to filter the users and use that computed property in the v-for directive instead:
computed: {
filteredUsers: function() {
let key = this.searchKey.toUpperCase();
return this.users.filter((user) => {
return user.name.toUpperCase().indexOf(key) !== -1
})
},
paginatedUsers: function() {
var list = this.filteredUsers;
this.resultCount = list.length
if (this.currentPage >= this.totalPages) {
this.currentPage = this.totalPages
}
var index = this.currentPage * this.itemsPerPage
return list.slice(index - 1, index - 1 + this.itemsPerPage)
}
}
<li v-for="user in paginatedUsers">{{ user.name }}</li>
Also, when using v-for to generate a range of numbers like you do for your page numbers, Vue version to starts the index at 1 instead of 0. So, you'll need to update the logic depending on a starting index of 0 as well.
Here's a working fiddle.
