A light XHR plugin for Vue 2.x and and above versions. It has many similar features with jQuery's ajax() and Angular's $http(). In addition to these, it also has its own important features:

• Assets
• Dynamic & async Vue components: (componentShifter)
• File uploading
• History
• Title
• Preventing dublicate requests

Setup

npm install vue-ajax-plugin --save

You have two ways to setup vue-ajax-plugin:

CommonJS (Webpack/Browserify)

• ES6

import ajax from 'vue-ajax-plugin'
Vue.use(ajax)

• ES5

var ajax = require('vue-ajax-plugin')
Vue.use(ajax)

Example

Vue.ajax.get('http://example.com').then(function(response) {
    console.log('Success', response.data)
}, function(response) {
    console.log('Error', response.statusText)
})

If you want to send data to the backend:

Vue.ajax.get('http://example.com', {
    param1: 'First parameter',
    param2: 'Second parameter'
}).then(function(response) {
    console.log('Success', response.data)
}, function() {
    console.log('Error', response.statusText)
})

Methods & Requests

Get Method

Vue.ajax.get(string url[, object data] [,object configurations])
    .then(function success[, function error])

Arguments

url: string
A string containing the URL to which the request is sent.

data: object|null
A plain object that is sent to the server with the request.

configurations: object|null
A set of key/value pairs that configure the Vue.ajax request.

Other methods and requests are the same:

Post Method

Vue.ajax.post(string url[, object data] [,object configurations])
    .then(function success[, function error])

Delete Method

Vue.ajax.delete(string url[, object data] [,object configurations])
    .then(function success[, function error])

Head Method

Vue.ajax.head(string url[, object data] [,object configurations])
    .then(function success[, function error])

Jsonp Request

Vue.ajax.jsonp(string url[, object data] [,object configurations])
    .then(function success[, function error])

Patch Method

Vue.ajax.patch(string url[, object data] [,object configurations])
    .then(function success[, function error])

Put Method

Vue.ajax.put(string url[, object data] [,object configurations])
    .then(function success[, function error])

All of the above methods are a shortcut method of the Vue.ajax():

Vue.ajax({
    url: 'http://example.com',
    method: 'get' // post, jsonp, etc
}).then(function(response) {
    console.log('Success', response.data)
}, function() {
    console.log('Error', response.statusText)
})

Response Handling:

Success and error together in then() method:

Vue.ajax(object configurations)
    .then(function success[, function error])

Success and error together in in separate methods:

Vue.ajax(object configurations)
    .then(function success)
    .catch(function error)

Component Shifter

With componentShifter() you can load (with Vue.ajax) and render your Vue template (html) in your application by dynamic & async Vue.component(). You can also add components and run them nested.

It also supports Vue.ajax's history feature. And the component is automatically update when navigating to the previous - next page.

vm.componentShifter(object configurations[, function success] [,function error])

• configurations: Object
  Vue.ajax configurations. For detailed information, see.
  Required properties:
  • is: (String) Component name
  • url: (String) Request url
• success: function
  Your custom callback on success.
• error: function
  Your custom callback on error.

Example

index.html

<div id="app">
    <a href="/page" @click.prevent="openPage('/page', 'New page')">Link</a>

    <!-- Your container component -->
    <component :is="myPage"></component>
</div>

app.js

var vm = new Vue({
    el: '#classest',
    data() {
        return {
            myPage: null, // Component name
            pageLoaded: false
        }
    },
    methods: {
        openPage(url, title) {
            // Calling componentShifter
            this.componentShifter({
                is: 'myPage', // Component name (Must be in quotes)
                url: url,
                title: title,
                history: true
            }, function (response) {
                console.log("Component changed!");
                pageLoaded = true;
            }, function (response) {
                console.log("Component could not be changed!", response);
                pageLoaded = false;
            });
        }
    },
    created() {
        if(!pageLoaded) {
            this.openPage('/page', 'New page')
        }
    }
});

Vue Ajax Configurations

Assets

Assets setting is used to push new asset files (CSS or JS) in the document. Available values, string or object.

Pushing single asset file

Vue.ajax.get('http://example.com', [data], {
    assets: 'path/css/style.css'
});

Pushing multiple asset files

Vue.ajax.get('http://example.com', [data], {
    assets: ['assets/css/style.css', 'assets/js/script.js']
});

Asynchronous

Asynchronous setting should be boolean. Default is true.

Vue.ajax.get('http://example.com', [data], {
    async: true
});

Cache

Cache setting should be boolean. Default value is false.

Vue.ajax.get('http://example.com', [data], {
    cache: false
});

Complete Event

Complete event setting should be function.

Vue.ajax.get('http://example.com', [data], {
    complete: function(response) {
        console.log(response.status)
    }
});

CSRF

CSRF setting should be boolean. Default value is true. However, in the html head tag it must be csrf-token meta. Like this:

<meta name="csrf-token" content="ABCDEFGHIJKLMN">

Vue.ajax.get('http://example.com', [data], {
    csrf: true
});

Data

Data setting should be object.

Vue.ajax('http://example.com', {
    url: 'http://example.com',
    method: 'get',
    data: {
        param1: 'First parameter',
        param2: 'Second parameter'
    }
});

File Uploading

File uploading setting should be DOM object. We recommend using the post method when uploading files. The important thing here is that you should not forget the name attribute.

<input type="file" name="my-input" id="my-input">

Vue.ajax.post('http://example.com', [data], {
    fileInputs: [
        document.getElementById('my-input')
    ]
});

You can only add the accept attribute to send images.

<input type="file" name="my-input-2" id="my-input-2" accept="image/*">

You can add the multiple attribute to send multiple files with an input element:

<input type="file" name="my-input-3" id="my-input-3" multiple>

History

History setting is usage of PushState (HTML history API). History setting should be boolean. Default value is false.

PushState (changing the URL of the page without refreshing the page) to create a faster browsing experience. This means less elements to load and therefore faster browsing.

Vue.ajax.get('http://example.com', [data], {
    history: true
});

Adding version for history
Layouts can be forced to do a hard reload when assets or html changes. First set the initial layout version in your header with a custom meta tag.

<meta http-equiv="x-history-version" content="ABCDEFGH">

HTTP Headers

HTTP headers setting should be object.

Vue.ajax.get('http://example.com', [data], {
    headers: {
        'Content-Type': 'application/json',
        'Accept': 'application/json, text/plain, */*'
    }
});

Method

URL data setting should be string. Available values are:

• delete
• get
• head
• jsonp
• patch
• post
• put

Vue.ajax({
    url: 'http://example.com',
    method: 'post'
});

Instead, you might prefer to use the following shorthand:

Vue.ajax.post('http://example.com', [data]);

Preventing Dublicate

This setting prevents sending dublicate requests to the same address or given key data.

Preventing dublicate setting should be boolean. Default value is true.

The following example prevents sending requests over the same URL:

Vue.ajax.get('http://example.com', [data], {
    preventDublicate: true
});

The following example prevents sending requests over the same given key data:

Vue.ajax.get('http://example.com', [data], {
    preventDublicate: true,
    key: 'ABCDEFGH'
});

Scroll Top

scrollTop setting is used to scroll to top of the document when loading the request. Default value is false.

Vue.ajax.get('http://example.com', [data], {
    scrollTop: true
});

Timeout

Timeout setting should be numeric. Default value is 60000 (60 seconds). (Time in milliseconds)

Vue.ajax.get('http://example.com', [data], {
    timeout: 60000
});

Title

Title setting is used to change the document title value. It should be string.

Vue.ajax.get('http://example.com', [data], {
    title: 'New title'
});

URL Data

URL data setting should be object. With this setting, you can add serialized query string to the URL you are sending.

Vue.ajax.get('http://example.com', [data], {
    urlData: [
        {page: 15},
        {category: 'Accessories'}
    ]
});

The URL will be like this when sending the request:
http://example.com?page=15&category=Accessories

With Credentials

With credentials setting should be boolean. Default value is false.

There is a detailed explanation here.

Vue.ajax.get('http://example.com', [data] {
    withCredentials: false
});

Response Handling

The response returns the object on the frontend. The object in general is the following structure:

{
    data: [object|null],
    status: [string],
    statusText: [string],
    headers: [string],
    config: [object],
    xhrStatus: [string]
    request: [object],
}

Response Format

If the content type on the server is "application/json", the response.data is automatically converted to a JSON object. If the content type is anything else, the result is returned as plain text.

PHP:

header('Content-type: application/json; charset=utf-8');
echo json_encode($array);

Laravel:

Route::get('respone', function () {
    return response(json_encode($array), 200)
        ->header('Content-Type', 'application/json; charset=utf-8');
});

VueJS

Vue.ajax.get('http://example.com', [data])
    .then(function(response) {
        console.log(response.data)
    });

Error Handling

In then() method

Vue.ajax.get('http://example.com/not-existing-path', [data])
    .then(function(response) {
        console.log(response.data)
    }, function(response) {
        console.log('Error: ', response.statusText);
    }); // "Error: Not Found"

In catch() method

Vue.ajax.get('http://example.com/not-existing-path', [data])
    .then(function(response) {
        console.log(response.data)
    }).catch(function(response) {
        console.log('Error: ', response.statusText);
    }); // "Error: Not Found"
