A practical walkthrough on building a micro frontend architecture with multiple Vue.js apps using single-spa. Note that you can replace Vue with your framework of choice.
The concept of micro frontends has been around for a while now but has been getting more attention in the past couple of years.
Evolution of the search term “Micro Frontend” on Google Trends, 2015–2020
Micro frontends extend the concept of backend micro-services: breaking down a web app (a monolith SPA) into distinct pieces. Then, through an orchestrator layer, each part is assembled (or composed) together. There are multiple ways of doing so. In our case we will do what is called client-side composition using single-spa.
At Unbabel we currently use a micro frontend architecture for one of our new customer-facing product.
Like any technical decision, there are gains and tradeoffs. We weighted a couple of factors when deciding for this approach:
You should consider these advantages:
You should consider these caveats:
In my experience, this approach is best when building a relatively large web app where you want to provide flexibility to multiple teams and have enough time to dedicate to governance and documentation.
Having said that, you can definitely leverage on many of the micro frontend advantages with a team of 2-3 people or even alone.

In this article, we are going to list out the most popular websites using Vue JS as their frontend framework.
Vue JS is one of those elite progressive JavaScript frameworks that has huge demand in the web development industry. Many popular websites are developed using Vue in their frontend development because of its imperative features.
This framework was created by Evan You and still it is maintained by his private team members. Vue is of course an open-source framework which is based on MVVM concept (Model-view view-Model) and used extensively in building sublime user-interfaces and also considered a prime choice for developing single-page heavy applications.
Released in February 2014, Vue JS has gained 64,828 stars on Github, making it very popular in recent times.
Evan used Angular JS on many operations while working for Google and integrated many features in Vue to cover the flaws of Angular.
“I figured, what if I could just extract the part that I really liked about Angular and build something really lightweight." - Evan You

Micro-frontends are the future of frontend web development. Inspired by microservices, which allow you to break up your backend into smaller pieces, micro-frontends allow you to build, test, and deploy pieces of your frontend app independently of each other. Depending on the micro-frontend framework you choose, you can even have multiple micro-frontend apps — written in React, Angular, Vue, or anything else — coexisting peacefully together in the same larger app!
In this article, we’re going to develop an app composed of micro-frontends using single-spa and deploy it to Heroku. We’ll set up continuous integration using Travis CI. Each CI pipeline will bundle the JavaScript for a micro-frontend app and then upload the resulting build artifacts to AWS S3. Finally, we’ll make an update to one of the micro-frontend apps and see how it can be deployed to production independently of the other micro-frontend apps.
Demo app — end result
Before we discuss the step-by-step instructions, let’s get a quick overview of what makes up the demo app. This app is composed of four sub-apps:
These four apps all live in separate repos, available on GitHub, which I’ve linked to above.
The end result is fairly simple in terms of the user interface, but, to be clear, the user interface isn’t the point here. If you’re following along on your own machine, by the end of this article you too will have all the underlying infrastructure necessary to get started with your own micro-frontend app!
Alright, grab your scuba gear, because it’s time to dive in!
To generate the apps for this demo, we’re going to use a command-line interface (CLI) tool called create-single-spa. The version of create-single-spa at the time of writing is 1.10.0, and the version of single-spa installed via the CLI is 4.4.2.
We’ll follow these steps to create the container app (also sometimes called the root config):
mkdir single-spa-demo
cd single-spa-demo
mkdir single-spa-demo-root-config
cd single-spa-demo-root-config
npx create-single-spa
We’ll then follow the CLI prompts:
3. Enter an organization name (I used “thawkin3,” but it can be whatever you want)
Great! Now, if you check out the single-spa-demo-root-config
directory, you should see a skeleton root config app. We’ll customize this in a bit, but first let’s also use the CLI tool to create our other three micro-frontend apps.
To generate our first micro-frontend app, the navbar, we’ll follow these steps:
cd ..
mkdir single-spa-demo-nav
cd single-spa-demo-nav
npx create-single-spa
We’ll then follow the CLI prompts:
Now that we’ve created the navbar app, we can follow these same steps to create our two page apps. But, we’ll replace each place we see “single-spa-demo-nav” with “single-spa-demo-page-1” the first time through and then with “single-spa-demo-page-2” the second time through.
At this point we’ve generated all four apps that we need: one container app and three micro-frontend apps. Now it’s time to hook our apps together.

In this tutorial, I will show you how to upload a file in Vue using vue-dropzone library. For this example, I am using Vue.js 3.0. First, we will install the Vue.js using Vue CLI, and then we install the vue-dropzone library. Then configure it, and we are ready to accept the file. DropzoneJS is an open source library that provides drag and drops file uploads with image previews. DropzoneJS is lightweight doesn’t depend on any other library (like jQuery) and is highly customizable. The vue-dropzone is a vue component implemented on top of Dropzone.js. Let us start Vue File Upload Using vue-dropzone Tutorial.
Dropzone.js is an open-source library providing drag-and-drop file uploads with image previews. DropzoneJS is lightweight, doesn’t depend on any other library (like jQuery), and is highly customizable.
The vue-dropzone is a vue component implemented on top of Dropzone.js.
First, install the Vue using Vue CLI.
Go to your terminal and hit the following command.
npm install -g @vue/cli
or
yarn global add @vue/cli
If you face any error, try running the command as an administrator.
Now, we need to generate the necessary scaffold. So type the following command.
vue create vuedropzone
It will install the scaffold.
Open the project in your favorite editor. Mine is Visual Studio Code.
cd vuedropzone
code .
I am using the Yarn package manager. So let’s install using Yarn. You can use NPM, also. It does not matter.
yarn add vue2-dropzone
or
npm install vue2-dropzone
Okay, now we need to add one css file with the above package. Now, vue cli uses css loader, so we can directly import in the src >> main.js entry file.
import Vue from 'vue'
import App from './App.vue'
Vue.config.productionTip = false
new Vue({
render: h => h(App)
}).$mount('#app')
import 'vue2-dropzone/dist/vue2Dropzone.css'
If importing css is not working for you, then you need to install that CSS file manually.
Copy this vue2Dropzone.css file’s content.
Create one file inside the src >> assets folder, create one css file called vuedropzone.css and paste the content there.
Import this css file inside src >> App.vue file.
<style lang="css">
@import './assets/vuedropzone.css';
</style>
Now, it should include in our application.
Our primary boilerplate has one ready-made component called HelloWorld.vue inside src >> components folder. Now, create one more file called FileUpload.vue.
Add the following code to FileUpload.vue file.
// FileUpload.vue
<template>
<div id="app">
<vue-dropzone id="upload" :options="config"></vue-dropzone>
</div>
</template>
<script>
import vueDropzone from "vue2-dropzone";
export default {
data: () => ({
config: {
url: "https://appdividend.com"
}
}),
components: {
vueDropzone
}
};
</script>
Here, our API endpoint is https://appdividend.com. It is the point where we will hit the POST route and store our image, but it is my blog’s homepage, so it will not work anyway. But let me import this file into App.vue component and see what happens.
// App.vue
<template>
<div id="app">
<FileUpload />
</div>
</template>
<script>
import FileUpload from './components/FileUpload.vue'
export default {
name: 'app',
components: {
FileUpload
}
}
</script>
<style lang="css">
@import './assets/vuedropzone.css';
</style>
Now, start the development server using the following command. It will open up URL: http://localhost:8080.
npm run serve
Now, after uploading the image, we can see that the image upload is failed due to the wrong POST request endpoint.
Install the Laravel.
After that, we configure the database in the .env file and use MySQL database.
We need to create one model and migration file to store the image. So let us install the following command inside the Laravel project.
php artisan make:model Image -m
It will create both the Image model and create_images_table.php migrations file.
Now, open the migrations file and add the schema to it.
// create_images_table.php
public function up()
{
Schema::create('images', function (Blueprint $table) {
$table->increments('id');
$table->string('image_name');
$table->timestamps();
});
}
Now, migrate the database table using the following command.
php artisan migrate
It creates the table in the database.
Now, we need to add a laravel-cors package to prevent cross-site-allow-origin errors. Go to the Laravel root and enter the following command to install it.
composer require barryvdh/laravel-cors
Configure it in the config >> app.php file.
Barryvdh\Cors\ServiceProvider::class,
Add the middleware inside app >> Http >> Kernel.php file.
// Kernel.php
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
\App\Http\Middleware\TrimStrings::class,
\Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
\App\Http\Middleware\TrustProxies::class,
\Barryvdh\Cors\HandleCors::class,
];
First, create an ImageController.php file using the following command.
php artisan make:controller ImageController
Define the store method. Also, create one images folder inside the public directory because we will store an image inside it.
Right now, I have written the store function that handles one image at a time. So do not upload multiple photos at a time; otherwise, it will break.
// ImageController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Image;
class ImageController extends Controller
{
public function store(Request $request)
{
if($request->file('file'))
{
$image = $request->file('file');
$name = time().$image->getClientOriginalName();
$image->move(public_path().'/images/', $name);
}
$image= new Image();
$image->image_name = $name;
$image->save();
return response()->json(['success' => 'You have successfully uploaded an image'], 200);
}
}
Go to the routes >> api.php file and add the following route.
// api.php
Route::post('image', 'ImageController@store');
We need to add the correct Post request API endpoint in FileUpload.vue component.
// FileUpload.vue
<template>
<div id="app">
<vue-dropzone id="drop1" :options="config" @vdropzone-complete="afterComplete"></vue-dropzone>
</div>
</template>
<script>
import vueDropzone from "vue2-dropzone";
export default {
data: () => ({
config: {
url: "http://localhost:8000/api/image",
}
}),
components: {
vueDropzone
},
methods: {
afterComplete(file) {
console.log(file);
}
}
};
</script>
Now, save the file and try to upload an image. If everything is okay, then you will be able to save the image on the Laravel web server as well as save the name in the database as well.
You can also verify on the server side by checking the database entry and the images folder in which we have saved the image.
The only required options are url, but there are many more you can use.
For example, let’s say you want:
export default {
data: () => ({
dropOptions: {
url: "https://httpbin.org/post",
maxFilesize: 5, // MB
maxFiles: 5,
chunking: true,
chunkSize: 400, // Bytes
thumbnailWidth: 100, // px
thumbnailHeight: 100,
addRemoveLinks: true
}
})
// ...
}
Happy Coding !!!
