  • πŸ”§ The --fix option on the command line (opens new window) can automatically fix some of the problems reported by this rule.

When using the data property on a component (i.e. anywhere except on new Vue), the value must be a function that returns an object.

# πŸ“– Rule Details

When the value of data is an object, it’s shared across all instances of a component.

<script> /* βœ“ GOOD */ Vue.component('some-comp', { data: function () { return { foo: 'bar' } } }) export default { data () { return { foo: 'bar' } } } </script>
Now loading...
<script> /* βœ— BAD */ Vue.component('some-comp', { data: { foo: 'bar' } }) export default { data: { foo: 'bar' } } </script>
Now loading...
