Supported operations (mode="operationName" in extender)

• append, prepend - appends or prepends markup to the queried node
• delete, remove - deletes node
• replace - replaces queried node with specified markup
• after, before - inserts markup before or after queried node

Usage example:

Base Component

<template>
    <div class="test-1">
        <div class="hello">Hello</div>
        <div class="hi">Hi</div>
    </div>
</template>

<script>
export default {
    name: 'Test1'
};
</script>

Extender Component

Don't forget to specify type="extend" in your template tag since without it loader will NOT process your template, and Vue will then completely replace the source template with it (breaking it ofc)

<template type="extend">
    <extenders>
        <!-- Attribute query is similar to css selector -->
        <extender query=".test-1" mode="append">
            <div class="howdy">Howdy!</div>
        </extender>
        <extender query=".hi" mode="delete" />
    </extenders>
</template>

<script>
import Test1 from 'src/test_1';

export default {
    name: 'Test2',
    extends: Test1,
    computed: {
        dizzy() {
            return true;
        }
    }
};
</script>

Result component

<template>
    <div class="test-1">
        <div class="hello">Hello</div>
        <div class="howdy">Howdy!</div>
    </div>
</template>

<script>
import Test1 from './test_1';

export default {
    name: 'Test2',
    extends: Test1,
    computed: {
        dizzy() {
            return true;
        }
    }
};
</script>
