Hello fellow developers! π Today, we are diving deep into the world of Vue.js 3. We will be going through the power and practicality of Mixins, a breathtaking feature of Vue.js. So, if you're ready to level up your Vue skills, keep reading!
Why Mixins? π€ Before we start, let's get a quick understanding. Mixins in Vue.js allow us to distribute reusable functionalities to our Vue components. They are a flexible way of distributing shared functionality between your components.
Now, let's dive into the practical part! Setting up a project in Vue.js is easy as 1,2,3.
npm install -g @vue/cli
vue create my-new-project
cd my-new-project
npm run serve
Now we've got our new Vue.js project up and running. Point your browser to http://localhost:8080 to see your project. π
Now, letβs create a mixin. For the purpose of this tutorial we'll call it loggerMixin
. Pretty straightforward. Our mixin will consist of a simple method that logs a message to the console.
// loggerMixin.js file
export default {
methods: {
logMessage(msg) {
console.log(msg);
}
}
};
Nice, our mixin is ready! Now, whatβs next? Well, we have to import and use it in a component. Letβs create a new vue component to use this mixin.
<template>
<div>
<button @click="logMessage('Mixins in action!')">Log message</button>
</div>
</template>
<script>
import loggerMixin from "@/mixins/loggerMixin.js";
export default {
mixins: [loggerMixin],
};
</script>
Voila! π That's how we've leveraged mixins within our Vue component. By clicking the button, you will see the message 'Mixins in action!' logged into your console. The logMessage
function coming from the loggerMixin
.
π Mixing it up Vue.js allows the use of multiple mixins within a single Vue component. Let's explore this functionality as well.
import loggerMixin from "@/mixins/loggerMixin.js";
import anotherMixin from "@/mixins/anotherMixin.js";
export default {
mixins: [loggerMixin, anotherMixin],
};
As you can see, simply include all the mixins you want within an array and Vue.js does the rest for you.
π Closing thoughts Skip through the Vue.js 3 documentation, and you'll find mixin code littered everywhere. Vue.js mixins assist in making code clearer and cleaner by preventing repetition and promoting reusability.
Remember, the beauty of code lies in DRY(don't repeat yourself) principles. I hope you found this post informative and helpful!
Happy coding, folks!π¨βπ»π©βπ»
