Vue.js is a powerful JavaScript framework that has gained popularity among developers for its simplicity and flexibility. With the recent release of Vue 3, developers have even more tools at their disposal to create dynamic and interactive web applications. In this article, I will dive deep into creating a login page using Vue 3, and share my personal experiences and insights along the way.
Getting Started with Vue 3
Before we start building our login page, let’s make sure we have Vue 3 installed. To do this, we can use the Vue CLI, a command-line tool that makes it easy to scaffold and manage Vue projects. If you haven’t installed it already, you can do so by running the following command in your terminal:
npm install -g @vue/cli
Once the installation is complete, let’s create a new Vue project by running the following command:
vue create login-page
This will create a new directory called login-page with all the necessary files and configurations for our Vue project.
Setting Up the Login Page
Now that we have our project set up, let’s start building our login page. We’ll begin by creating a new Vue component called LoginPage. In the src/components directory, create a new file called LoginPage.vue and add the following code:
<template>
<div class="login-page">
<h2>Welcome Back!</h2>
<form @submit.prevent="login">
<label for="email">Email:</label>
<input type="email" id="email" v-model="email" required>
<label for="password">Password:</label>
<input type="password" id="password" v-model="password" required>
<button type="submit">Log in</button>
</form>
</div>
</template>
<script>
export default {
data() {
return {
email: '',
password: '',
};
},
methods: {
login() {
// Logic for authenticating the user
},
},
};
</script>
<style scoped>
.login-page {
max-width: 400px;
margin: 0 auto;
padding: 20px;
background-color: #f7f7f7;
border: 1px solid #ddd;
border-radius: 4px;
}
h2 {
margin-bottom: 20px;
}
label {
display: block;
margin-bottom: 10px;
}
input {
width: 100%;
padding: 10px;
margin-bottom: 20px;
}
button {
padding: 10px 20px;
background-color: #007bff;
color: #fff;
border: none;
border-radius: 4px;
cursor: pointer;
}
</style>
In the code above, we have defined a simple form that takes an email and password input, and a submit button. We have also added some basic styling using CSS.
Handling Form Submission
Now that we have our login page set up, let’s add some logic to handle the form submission. In the LoginPage.vue component, add the following code to the methods section:
methods: {
login() {
// Logic for authenticating the user
if (this.email === '[email protected]' && this.password === 'password') {
// Redirect the user to the dashboard
} else {
// Display an error message
}
},
},
Inside the login method, we can perform the necessary authentication logic. In this example, we are simply checking if the email and password match a predefined set of credentials. If the user is authenticated, we can redirect them to the dashboard. Otherwise, we can display an error message.
Conclusion
Building a login page in Vue 3 is straightforward and can be customized to fit your specific requirements. In this article, we explored the basics of creating a login page using Vue 3 and added some personal touches along the way. We covered how to set up the project, create the login page component, handle form submission, and add basic authentication logic.
Vue 3 provides developers with a powerful and intuitive framework for building modern web applications. With its reactive data binding and component-based architecture, Vue 3 makes it easy to create dynamic and responsive user interfaces. So why not give it a try and start building your own login page using Vue 3?
