Step 1 : Create a Vue CLI Project

Go to your projects directory and create a project by typing this:

vue create vuejs-cli-api-get-request

Go to the folder:

cd vuejs-cli-api-get-request

Step 2 : Install Necessary Dependencies

At first, let’s install Axios by typing this command:

npm install axios --save

For front-end, we are going to install bootstrap, jQuery, and popper.js. We can install these three by one command:

npm install bootstrap jquery popper.js --save

Step 3 : Add Bootstrap to Project

We have already installed Bootstrap in our project. Open main.js from src folder using an editor and add these two lines:

import 'bootstrap'
import 'bootstrap/dist/css/bootstrap.min.css'

So, the main.js looks like:

import Vue from 'vue'
import App from './App.vue'

import 'bootstrap'
import 'bootstrap/dist/css/bootstrap.min.css'

Vue.config.productionTip = false

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

Step 4 : Import Axios and Create Get Method

Go to src folder and open App.vue file. We are going to import axios and create a get method. We are going to take dummy data from
https://reqres.in/api/users?page=1.

<script>
import axios from "axios";

export default {
  name: 'app',
  data () {
    return {
      loading: false,
      all_users: null
    }
  },
  mounted () {
    this.loading = true;
    axios
      .get('https://reqres.in/api/users?page=1')
      .then(response => (this.all_users = response.data.data))
      .catch(error => console.log(error))
      .finally(() => this.loading = false)
  }
}
</script>

Step 5 : The Final App.vue File

We have completed our javascript part. Let’s bind to html. So, the final App.vue looks like:

<template>
  <div id="app" class="container">
    <p v-if="loading">Loading...</p>
    <div v-else>
      <h3 class="heading">Users</h3>
      <table class="table table-bordered">
        <thead>
          <tr>
            <th scope="col">ID</th>
            <th scope="col">Avatar</th>
            <th scope="col">Name</th>
            <th scope="col">Email</th>
          </tr>
        </thead>
        <tbody>
          <tr v-for="user in all_users" v-bind:key="user">
            <td>{{ user.id }}</td>
            <td><img v-bind:src="user.avatar" width="50"/></td>
            <td>{{ user.first_name + " " + user.last_name }}</td>
            <td>{{ user.email }}</td>
          </tr>
        </tbody>
      </table>
    </div>
  </div>
</template>

<script>
import axios from "axios";

export default {
  name: 'app',
  data () {
    return {
      loading: false,
      all_users: null
    }
  },
  mounted () {
    this.loading = true;
    axios
      .get('https://reqres.in/api/users?page=1')
      .then(response => (this.all_users = response.data.data))
      .catch(error => console.log(error))
      .finally(() => this.loading = false)
  }
}
</script>

<style>
#app {
  text-align: center;
  margin-top: 50px;
}
.heading {
  margin-bottom: 30px;
}
</style>

Step 6 : Add ESLint File to Ignore Errors

As we aren’t using webpack for this project, we have to do it manually. In the root folder create a file named “.eslintrc.js“. Then open it and paste this:

module.exports = {
	parser: 'babel-eslint',
	parserOptions: {
		sourceType: 'module'
		ecmaFeatures: {
			experimentalObjectRestSpread: true
		}
	},
	extends: [
		'plugin:vue/recommended'
	],
	rules: {
		"comma-dangle": 0,
		"no-unused-vars": "warn",
		"no-console": 1,
		"no-mixed-spaces-and-tabs": 0,
		"no-unexpected-multiline": "warn"
	}
}

Step 7 : Run and Test

Now let’s run the app:

npm run serve

Visit the project URL http://localhost:8080 and see the output:

You can download this project from GitHub.

Our project is done.
