Condition on value for style on Vue.js

Question

I'd like to check the value of my template

        <template slot="projected_end_date" slot-scope="{ line }">
            <datetime-display :value="line.projected_end_date"
                              type="date"
            style= "color: red"></datetime-display>
         </template>

and only set the style for red color when my value is less than current date. Any suggestion? I'm assuming it should be something like

value > DateHelper.now()? style = ...

Take a look at Class and Styles Bindings

You can use it like:

<div :class="{'my-class': myCondition}">

Simple example

new Vue({
  el: '#app',
  data: {
    selectedColor: 'red'
  }
})

.red { background: red}
.blue { background: blue}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.13/vue.js"></script>

<div id="app">
  <button @click="selectedColor='red'">Red</button>
  <button @click="selectedColor='blue'">Blue</button>
  <p :class="{red: selectedColor === 'red', blue: selectedColor === 'blue'}">the background color will change !</p>
</div>
