Question

What are the different ways to create filters in VueJS?

Answer 1

You can define filters in two ways,

1. Local filters: You can define local filters in a component’s options. In this case, filter is applicable to that specific component.

filters: {
  capitalize: function (value) {
    if (!value) return ''
    value = value.toString()
    return value.charAt(0).toUpperCase() + value.slice(1)
  }
}

2. Global filters: You can also define a filter globally before creating the Vue instance. In this case, filter is applicable to all the components with in the vue instance,

Vue.filter('capitalize', function (value) {
  if (!value) return ''
  value = value.toString()
  return value.charAt(0).toUpperCase() + value.slice(1)
})

new Vue({
  // ...
})
