SVG File With Dynamic Fill Colors – Vue

November 6, 2022

I am making a twitter clone application with VueJS 3.

I saved Twitter’s logo as a .svg file and can use it with the <img /> tag. I can also change its color when I give the <svg> tag the fill="#fff" attribute. However, I want to use this .svg file in multiple places and in different colors.

So I tried to dynamically change the color of the svg by giving the <img /> tag the classes fill-white, bg-white and text-white, but it didn’t work.

My Currently .svg File – With White Color

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 24 24" aria-hidden="true">
    <g>
        <path fill="#fff" d="M23.643 4.937c-... 1.7-1.477 2.323-2.41z"></path>
    </g>
</svg>

Img Tag

<img
 src="/twitter-bird.svg"
 draggable="false"
 class="w-52 lg:w-96 fill-white"
 alt="Twitter Bird"
/>

I Tried This On .svg File

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 24 24" aria-hidden="true">
    <g>
        <path fill="params(fill) #fff" d="M23.643 4.937c-... 1.7-1.477 2.323-2.41z"></path>
    </g>
</svg>

I understand that I need to make this svg’s color editable. But I couldn’t find how to do this.

>Solution :

You can make component from svg file and bind fill to prop:

const app = Vue.createApp({
  data() {
    return {
      colors: ['#8A2BE2', 'rgb(255,255,0)', '#008000'],
    };
  },
})
app.component('myImg', {
  template: `
    <svg height="40" viewBox="0 0 107.1 107.1" style="enable-background:new 0 0 107.1 107.1;" xml:space="preserve">
    <path :fill="color" d="M2.287,47.815l23.096,19.578L18.2,96.831c-1.411,5.491,4.648,9.998,9.575,6.901L53.55,87.813l25.774,15.916   c4.79,2.955,10.844-1.408,9.576-6.902l-7.184-29.435l23.099-19.579c4.363-3.661,2.111-10.844-3.662-11.267l-30.282-2.255   L59.464,6.266c-2.112-5.211-9.577-5.211-11.832,0L36.225,34.292L5.944,36.547C0.174,37.113-2.081,44.154,2.287,47.815z"/>
  </svg>
  `,
  props: ['color']
})
app.mount('#demo')

<script src="https://unpkg.com/vue@3/dist/vue.global.prod.js"></script>
<div id="demo">
  <div v-for="col in colors">
    <my-img :color="col"></my-img>
  </div>
</div>
