Import svg inline and modify element to create icon

Svg-icon.vue

<script>
function recursivelyRemoveFill(el) {
    if (!el) {
        return;
    }
    el.removeAttribute('fill');
    [].forEach.call(el.children, child => {
        recursivelyRemoveFill(child);
    });
}
export default {
    name: 'svg-icon',
    props: {
        icon: {
            type: String,
            default: null
        },
        hasFill: {
            type: Boolean,
            default: false
        },
        growByHeight: {
            type: Boolean,
            default: true
        },
    },
    mounted() {
        if (this.$el.firstElementChild.nodeName === 'svg') {
            const svgElement = this.$el.firstElementChild;
            // use `viewBox` attribute to get the svg's inherent width and height
            const viewBox = svgElement.getAttribute('viewBox').split(' ').map(n => Number(n));
            const widthToHeight = (viewBox[2] / viewBox[3]).toFixed(2);
            if (this.hasFill) {
                // recursively remove all fill attribute of element and its nested children
                recursivelyRemoveFill(svgElement);
            }
            // set width and height relative to font size
            // if growByHeight is true, height set to 1em else width set to 1em and remaining is calculated based on widthToHeight ratio
            if (this.growByHeight) {
                svgElement.setAttribute('height', '1em');
                svgElement.setAttribute('width', `${widthToHeight}em`);
            } else {
                svgElement.setAttribute('width', '1em');
                svgElement.setAttribute('height', `${1 / widthToHeight}em`);
            }
            svgElement.classList.add('svg-class');
        }
    }
}
</script>

<template>
    <div v-html="require(`!html-loader!../assets/svg/${icon}.svg`)" class="svg-container"></div>
</template>

<style lang="scss" scoped>
.svg-container {
    display: inline-flex;
}
</style>

I use the icon prop to change toggle states, and changes in the category indicator icon of items that can be sorted in categories by the user.

The other props may change depending on the icon change. However, the one time I might have had to use it previously I just ended up fixing the inconsistent icon instead. So yeah, you could have just the watcher on the icon prop.

That's a cool use case. For the scope of the article, I will skip adding it since I just want to highlight basic functionality. Thanks for your feedback and input though! 👍
