Learn how to convert data to lowercase using Vue.js 2

I am attempting to convert some data to lowercase (always lowercase)

I am creating a search input like :

<template id="search">
    <div>
        <input type="text" v-model="search">
        <li v-show="'hello'.includes(search) && search !== ''">Hello</li>
    </div>
</template>

Vuejs : (component)

Vue.component('search', {
    template : '#search',
    data: function(){return{
        search : '',
    }}
});

I have attempted using the watch method, but I do not want the input showing in lowercase while typing

watch: {
    'search' : function(v) {
        this.search = v.toLowerCase().trim();
    }
}

Demo : https://jsfiddle.net/rgr2vnjp/

Furthermore, I prefer not to add .toLowerCase() on the search list v-show like :

<li v-show="'hello'.includes(search.toLowerCase()) && search !== ''">Hello</li>

Any suggestions? I have researched and found many suggesting to use filter, but it is not available in Vuejs 2

Playground : https://jsfiddle.net/zufo5mhq/ (Try typing H)

PS: Any tips for good / better code would also be appreciated. Thank you

Vue.js 2.0 introduces a new way to handle data manipulation using computed properties instead of filters:

computed: {
  convertToUppercase() {
    return this.text.toUpperCase();
  }
}

Now you can easily implement the convertToUppercase computed property in your template:

<span v-show="convertToUppercase === 'HELLO'">Hello</span>

It is recommended to consolidate all of the logic within a computed property in order to maintain a clear separation between the logic and the view/template:

computed: {
  displayGreeting() {
    const formattedSearch = this.search.toLowerCase().trim()
    return 'hello'.includes(formattedSearch) && this.search !== ''
  }
}

Subsequently, in your template:

<li v-show="displayGreeting">Hello</li>

To effortlessly incorporate lowercase text into your Vue application, I find that utilizing Vue filters is the way to go: https://v2.vuejs.org/v2/guide/filters.html

<template>
  <div>
    {{ name | lowercase}}
  </div>
</template>

<script>
  export default {
    data: () => ({
      name: 'I AM ROOT'
    })
    filters: {
      lowercase: function (value) {
        if (!value) return ''
        return (value.toString().toLowerCase())
      }
    }

  }
</script>
