How to prepare our application for production with Vue Router?
We are on the verge of sending our application to production! Before letting off the fireworks, we need to make some key adjustments to our Vue application, especially in the use of Vue Router and dynamic routes. Here we will cover how to optimize our code and deliver a seamless user experience.
How do we use RouterLink dynamically in Vue?
We can enhance our application by using RouterLink
to display dynamic links that are received from a parent component. To do this, we must add a property in our props
component to handle the list oflinks
. Here is how we can configure RouterLink
to display each link received.
<template> <div> <router-link v-for="link in links" :to="link.to"> {{ link.title }} </router-link> </div></template>
<script>export default { props: { links: { type: Array, default: () => [] } } }</script> </script>
How to solve common problems with dynamic routes and Vue Router?
A common problem when working with dynamic routes is that when changing a parameter in the URL, the corresponding component is not recreated from scratch, which can result in the content not being updated as expected. Fortunately, we can solve this by using a 'watcher'.
<script>export default { watch: { '$route.params': 'fetchData' }, methods: { fetchData() { // logic for fetching new information } } }</script>
How to implement a cryptocurrency conversion function?
Cryptocurrency conversion functionality is crucial, especially if you want your application to be dynamic and useful. To enable conversions between currencies, you will use a computed property
that manipulates the entered value and transforms it as needed.
<template> <div> <input v-model="convertValue" @input="convertCurrency"/> <button @click="toggleConversion">Change Dollar/Bitcoin</button> <span>{{ convertedValue }}</span> </div></div> </template>
<script>export default { data() { return { fromDollar: true, convertValue: null, } }, computed: { convertedValue() { if (!this.convertValue) return 0; return this.fromDollar ? this.convertValue / this.currentPrice : this.convertValue * this.currentPrice; } } }, methods: { toggleConversion() { this.fromDollar = !this.fromDollar; } } }</script>
What else should we consider before taking the Vue application to production?
In addition to technical functionality, it is crucial to improve the user experience and optimize the small details. This involves styling components appropriately, ensuring that the interface is intuitive and user-friendly, and fixing minor bugs, such as handling loading
correctly.
<template> <button v-if="!isLoading">Get Link</button> <span v-if="isLoading">Loading...</span></template>
<script>export default { data() { return { isLoading: false } }, methods: { fetchData() { this.isLoading = true; setTimeout(() => this.isLoading = false, 2000); // simulating wait } }</script> </script>
With all these elements in place, your Vue application is almost ready for the big exit! Stay tuned for the next steps where you will learn how to definitely move your application to production and let the whole world enjoy it. Keep learning and never stop improving your skills!
