Create Scalable Vue.js Application with Azure Static Web Apps

Have you joined Microsoft Build 2020, where Microsoft introduced various exciting news to the world? Among all of the updates, I am especially keen to introduce Azure Static Web Apps, the hosting service for static website which has been finally announced as Public Preview, and that enables us to create & deploy Vue.js Web application literally within “a few minutes”.

Vue.js is made based on the concept of “Progressive Framework”, hence we can start writing from very small, and gradually grow them into the enterprise
scale. In this post, I would like to introduce the first step to create scalable application using Vue.js and Azure Static Web Apps.

Creating new project with Vue CLI

In order to be ready to use Azure Static Web Apps, your application code needs to be on GitHub. First, write some basic code. A shortcut to create Vue.js project is to use Vue CLI. For example, with Vue CLI, you can configure Router, or TypeScript in the appropriate way.

Let’s get started. Using Terminal, move to directory where the application will be created to run the command like below,

npm i -g @vue/cli
vue create .

Next, create the project with frequently-used configuration with Vue CLI prompt. I choose TypeScript here because I believe TypeScript is going to be major in Vue.js project. Also, select Router, ESLint, Prettier and Jest which is majorly used in many projects. For “Use class-style component syntax?”, I suggest to select “No” since it is not longer mainstream with Vue.3x.

Vue CLI v4.3.1
? Please pick a preset: Manually select features
? Check the features needed for your project: TS, Router, Linter, Unit
? Use class-style component syntax? No
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? No
? Use history mode for router? (Requires proper server setup for index fallback in production) Yes
? Pick a linter / formatter config: Prettier
? Pick additional lint features: Lint on save   
? Pick a unit testing solution: Jest
? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config files
? Save this as a preset for future projects? (y/N) N

After a while, Vue.js project will be generated. Let’s check if application runs properly on local.

npm run serve

If the green Vue.js logo on the initial screen shows up, the basic configuration is all set up. You can already run not only TypeScript compile but also unit testing and formatting. The rest is just to add the code for features of the your application!

At this point, push codes to GitHub in order to get ready for the deploy to Azure.

Provisioning Azure Static Web Apps

Open Azure portal and go to “Create a resource”, and search “static web apps”. Fill in all the necessary information as follow. In this process, you link this resource with the GitHub Repo.

Click “Next:Build”, and it takes you to the next step. In this step, type “dist” for “App artifact location”. “dist” is a directory which outputs the static files for hosting , such as HTML,CSS, Javascript when we run npm run build (standard build command of Vue CLI) .

Review and Create

Click “Review + Create”and and wait a few minutes, deployment is complete! You don’t need to configure CI service or write the build script in YAML.

At this point, build workflow of GitHub Actions runs automatically in the background. To check the build status, you can open Actions tab in GitHub. If the Icon is green, then the build and deploy is successfully completed.

GitHub actions

Now, let’s go back to the Azure portal and click the site URL. You will see the same page published as the application you ran locally.

At this moment, YAML file is already added to .github/workflows in GitHub repository, so do not forget to pull them to local.

Setting fallback routes

We selected “History Mode” when we set up Router with Vue CLI. In the SPA, re-loading a specific page cause 404 if we do not configure anything on the hosting environment.

To enable History Mode in a hosting environment, you need to make the appropriate setting for the environment. In case of hosting Vue.js on Azure Static Web Apps, create routes.json file under public directory like below.

  "routes": [
      "route": "/*",
      "serve": "/index.html",
      "statusCode": 200

So, let’s push this change to brunch and create pull request.

Pull Request

Here, The pull request is triggered and the deployment to Static Web Apps is executed. Once build process is completed, you can confirm the deployed change under “Environments” in Azure Portal.

Let’s check “about” page which we had problem with earlier. Now, it no longer shows 404 page after reloading.

All you have to do for the rest is just to merge pull request and wait for it being deployed to “production” environment. When pull request is closed, staging environment will be automatically deleted.

I hope you experienced how easy it is to host scalable Vue.js application with Azure. Azure Static Web Apps is currently available to Public Preview, for free! Who wouldn’t try it?
