What are refs in Vue.js and how do I use them?

MagicBuddy
MagicBuddy

Refs in Vue.js are a way to directly access DOM elements or child components. You can use the ref attribute to register a reference to an element or component, and then access it in your script using this.$refs.

Can you give me an example of how to use refs?

Sure! Here's a simple example:

<template>
  <div>
    <input ref="myInput" />
    <button @click="focusInput">Focus Input</button>
  </div>
</template>

<script>
export default {
  methods: {
    focusInput() {
      this.$refs.myInput.focus();
    }
  }
}
</script>

Are there any limitations to using refs?

MagicBuddy
MagicBuddy

Yes, refs should be used sparingly. They can make your code harder to maintain and test. It's best to use them when you need direct access to a DOM element or a child component.

You

When should I prefer using refs over Vue's reactive data?

MagicBuddy
MagicBuddy

You should prefer using reactive data for most cases, especially for managing state. Use refs when you need to interact directly with the DOM or when you need to access a child component's methods.
