Is going too deep a bad practice in Vue.js?

Unleashing the full potential of Vue.js component styling involves leveraging the power of ::v-deep to target CSS classes within nested components, as shown below:

<template>
  <div class="parent">
    <Child /> <!-- contains .grandchild CSS class -->
  </div>
</template>

// ...

<style lang="scss" scoped>
.parent {
  ::v-deep {
    .grandchild {
      display: block;
    }
  }
}
</style>

Question arises - is it wise to utilize v-deep when there's a risk of breaking consumers of Child by renaming or removing .grandchild, possibly making it a bad practice?

Answer №1

The importance of context cannot be overstated, especially when dealing with components that are off limits for direct modifications, like third party components. In most scenarios, adhering to best practices such as employing props to control child component styles or utilizing global CSS is advisable.

Therefore, resorting to ::v-deep should only be considered as a final solution when all other avenues have been exhausted.
