Simple Guide to Sending POST Requests in Vue.js Using Axios

Hello Developers! 👋

In this tutorial, we'll show you how to send HTTP POST requests in Vue.js using the popular Axios library. Axios makes it easy to interact with APIs and submit data without reloading the page. Whether you're passing form data, arrays, or other parameters, Axios handles it all with ease.

In this example, we’ll create a simple form in a Vue.js app where users can submit their name and description. We’ll then send this data to a server using a POST request.

Let’s break it down step by step:

Step 1: Set Up Your Vue.js App

Start by creating a new Vue.js project using Vue CLI. Run the following command in your terminal:

vue create my-app

Step 2: Install Axios and Vue-Axios

Next, you need to install the necessary packages to use Axios in your Vue.js project. Run this command in your project directory:

npm install --save axios vue-axios

Step 3: Configure Axios in Your App

To use Axios in your app, you need to import and configure it in the main.js file. Here's how:

import Vue from 'vue';
import App from './App.vue';
import axios from 'axios';
import VueAxios from 'vue-axios';

Vue.use(VueAxios, axios);
Vue.config.productionTip = false;

new Vue({
  render: h => h(App),
}).$mount('#app');

Step 4: Create the Form Component

Now, let's create a component where users can enter their name and description. We'll send this data to the server when the form is submitted.

Create the HelloWorld.vue file inside the src/components/ folder with the following code:

<template>
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Vue Axios POST Request Example</div>
                    <div class="card-body">
                        <form @submit="submitForm">
                            <strong>Name:</strong>
                            <input type="text" class="form-control" v-model="name" required>
                            <strong>Description:</strong>
                            <textarea class="form-control" v-model="description" required></textarea>
                            <button class="btn btn-success">Submit</button>
                        </form>
                        <strong>Response:</strong>
                        <pre>{{ output }}</pre>
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>

<script>
export default {
    data() {
        return {
            name: '',
            description: '',
            output: ''
        };
    },
    methods: {
        submitForm(e) {
            e.preventDefault();
            let currentObj = this;

            // Send POST request using Axios
            this.axios.post('http://localhost:8000/yourPostApi', {
                name: this.name,
                description: this.description
            })
            .then(response => {
                currentObj.output = response.data;
            })
            .catch(error => {
                currentObj.output = error;
            });
        }
    }
}
</script>

Step 5: Run Your App

Once everything is set up, you can run your app with the following command:

npm run serve

This will start the Vue app, and you should see the form ready for submission.

Key Points to Remember:

• Axios is a powerful HTTP client that makes sending requests easy.
• You can send both simple and complex data using POST requests.
• In this example, we used Vue's two-way data binding (v-model) to capture user input and send it to the server.

That's it! You’ve successfully set up a simple Vue.js form with Axios to send POST requests. I hope you found this tutorial helpful! If you have any questions, feel free to leave a comment below. Happy coding! 🚀
