Why?

It uses render to handle the highlighted text instead of using v-html or el.innerHtml.

Usage

To use it, just provide it with an array of search terms and a body of text to highlight.

<template>
  <div id="app">
    // attrs on component are applied to the wrapper `<span>`
    <Highlighter class="my-highlight" :style="{ color: 'red' }"
      highlightClassName="highlight"
      :searchWords="keywords"
      :autoEscape="true"
      :textToHighlight="text"/>
  </div>
</template>

<script>
import Highlighter from 'vue-highlight-words'

export default {
  name: 'app',
  components: {
    Highlighter
  },
  data() {
    return {
      text: 'The dog is chasing the cat. Or perhaps they\'re just playing?',
      words: 'and or the'
    }
  },
  computed: {
    keywords() {
      return this.words.split(' ')
    }
  }
}
</script>

And the Highlighter will mark all occurrences of search terms within the text:
