Topic: Exported component via vue-cli not looking as intended

Kalkowski free asked 4 years ago


Hi there.

I am using MDB Vue Pro to create my components. When I export them via vue-cli as single web component, the component does not look like expected. The export was made this way:

vue-cli-service build --target wc --name star-rating ./src/components/StarRating.vue

Expected behavior

The component should look like this when using it outside of vue, for example in plain html:

enter image description here

Actual behavior

At the moment, it looks like this:

Resources (screenshots, code snippets etc.)

Below the code of the StarRating.vue component:

<template>
<div class="StarRatingComponent">
    <media :query="{minWidth: sm}">
        <div>
            <div :ratings="ratings" v-for="(rating, index) in ratings">
                <mdb-container>
                    <mdb-row>
                        <mdb-col offsetMd="1" md="3">
                            <mdb-rating

                                    far
                                    disabled
                                    :value="parsedRating(index)"

What am I doing wrong? Thank you in advance!

Hi there,

The problem is connected with Vue Web Components itself, not with the MDB library. As Web Components are not plain html elements, they won't catch styles from outside. We don't recommend this way of exporting components. We strongly advice to build them as a Universal Module Definition. Here's the script:

vue-cli-service build --target lib --dest lib/components/${componentName} --formats umd-min --name ${componentName} --filename ${componentName} ./src${componentPath}${componentExt}

Best regards
