Setup a Micro Frontend Architecture With Vue and single-spa

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.

What are Micro Frontends?

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.

When should I use this approach?

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:

  • The product to build would be comprised of at least 6 distinct areas, i.e. interfaces;
  • Several multi-disciplinary teams would own and have full autonomy on delivering parts of the product;
  • Have the possibility of partially changing parts of the product’s stack. Although Vue is the company’s framework of choice, we don’t know if it’ll still be what we want to use 3 years from now;

You should consider these advantages:

  • Teams have a greater autonomy on delivering value into the product at different paces as their development can be largely independent from other teams;
  • Ability to have totally separate repositories, test and deployment flows;
  • Ability to easily override parts of an application’s interface (i.e. A/B testing, incremental rollout);
  • Use different frameworks side-by-side or perform experiments without affecting other parts of your application;
  • Ability to refactor parts of your product without having to change it all at once;

You should consider these caveats:

  • Increased overhead to set up, deploy and maintain depending on the scope and characteristics of the product you’re building;
  • More moving parts: it’s important to have a solid documentation on how everything is setup and relates as well as defining guidelines that govern how development is to be done within the architecture;
  • Steeper learning for developers to understand the architecture, its lifecycle and dependencies. Hence having thorough documentation is imperative;
  • Micro frontends are still relatively new and there is no one-size-fits-all methodology or well established consensus on how to achieve this. Be ready to do a fair amount of R&D depending on your case;

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.

8 Popular Websites That Use The Vue.JS Framework

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

How To Develop And Deploy Micro-Frontends Using Single-Spa Framework

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.

Overview of the Demo App

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:

  1. A container app that serves as the main page container and coordinates the mounting and unmounting of the micro-frontend apps
  2. A micro-frontend navbar app that’s always present on the page
  3. A micro-frontend “page 1” app that only shows when active
  4. A micro-frontend “page 2” app that also only shows when active

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!

Creating the Container App

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:

  1. Select “single spa root config”
  2. Select “yarn” or “npm” (I chose “yarn”)

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.

Creating the 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:

  1. Select “single-spa application / parcel”
  2. Select “react”
  3. Select “yarn” or “npm” (I chose “yarn”)
  4. Enter an organization name, the same one you used when creating the root config app (“thawkin3” in my case)
  5. Enter a project name (I used “single-spa-demo-nav”)

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.

Vue File Upload Using vue-dropzone Tutorial

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.

Step 1: Install Vue.js 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 .

Step 2: Install vue-dropzone.

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.

Step 3: Upload an Image.

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.

Step 4: Create Laravel API for the 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,
];

Step 5: Define the API route and method to store the image.

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');

Step 6: Edit FileUpload.vue component.

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.

Step 7: More vue-dropzone configuration.

The only required options are url, but there are many more you can use.

For example, let’s say you want:

  • A maximum of 4 files
  • 2 MB max file size
  • Sent in chunks of 500 bytes
  • Set a custom thumbnail size of 150px
  • Make the uploaded items cancelable and removable (by default, they’re not)
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 !!!
