// new Vue ...

SomeComponent.vue

<template>
  <text-highlight :queries="queries">{{ description }}</text-highlight>

Output

More Options

All available props in TextHighlight component are:

queries: Array<String|RegExp>|String|RegExp

This prop accepts string, regex, and array of strings or regex. If array is given, it will highlight the union of matched strings/regex globally.
[caseSensitive]: Boolean

Whether string being searched is case sensitive.
[diacriticsSensitive]: Boolean

Whether string being searched is diacritics sensitive.
[highlightStyle]: Object|Array|String

Styles to be applied to highlighted <mark>. Similar to style bindings in vue, it accepts Array syntax, Object syntax, or plain styling as String. This prop will then be merged with default highlight styles in TextHighlight component. See style binding in Vue.js.
[highlightClass]: Object|Array|String

Classes to be added to highlighted <mark>. Similar to class bindings in vue, it accepts Array syntax, Object syntax, or class as String. See class binding in Vue.js.
[highlightComponent]: Object|String

By default vue-text-highlight uses <mark> for the highlighting. Pass this props to override with other tag (string) or custom component (Vue component definition).

This component will be passed with two props from text-highlight:
- index: Number
  
  Index of highlighted component.
- text: String
  
  Highlighted words, equals to this.$slots.default[0].text
For more details, see example below.
Other props and listeners that are not listed above are forwarded to the highlighted component. These props will be merged with higher precendence than index and text passed from text-highlight.

Advanced Usage

There might be a case where you want to do more things with the highlighted words. For that reason, vue-text-highlight supports custom component for the highlighted words. In this case, the following example alerts on click.

OtherComponent.vue

<template>
  <text-highlight
    :queries="queries"
    :highlightComponent="MyClickableComponent"
    :baz="foo"
    @customlistener="alert"
  >
    {{ description }}
  </text-highlight>
</template>

import MyClickableComponent from 'MyClickableComponent';

data() {
  return {
    queries: ['birds', 'scatt'],
    description: 'Tropical birds scattered as Drake veered the Jeep'
    MyClickableComponent,
    foo: 'bar',
  };
},
methods: {
  alert() {},
}

MyClickableComponent.vue

<template>
  <mark class="custom" @click="$emit('customlistener')">
    <slot></slot>
  </mark>
</template>

props: {
  baz: String, // From OtherComponent.vue
  index: Number, // From TextHighlight
  text: String, // From TextHighlight, equals to `this.$slots.default[0].text`
}
