Deploy your SPA to Azure

In this post I want to share a simple tutorial on how to deploy your single page application into the Azure cloud.

The goal

Here is the initial setup:

  • I have a Single Page Application (SPA) done with HTML/JavaScript in a separate local Git repository

  • I have a ASP.NET 4.6 Web API service which serves the data for SPA in another local Git repository

  • Now I want to deploy both to the Azure cloud, and make it easy to deploy changes in the future

The solution

We will deploy our application to Azure Cloud Services / Web application.

  1. Go to Azure Portal then App Services -> Add and follow the wizard to create your Web app. Here is mine: Azure web app

  2. Follow this guide to create a new Git repository and setup continuous deployment from this repository to Azure web application. You are good once you see this working (step 6): Hello git running in Azure

  3. Copy your SPA files into the root of the new Git repository, here is my repo after I did that: SPA files in the repo and push them to azure remote. Now you should be able to browse to the web app and see your SPA screen, but with all calls to Web API failing.

  4. Inside your new Git repository, create a sub-folder to host Web API services. My SPA expects them under /api folder, so that’s the folder name that I created: Web API files in the repo

  5. Copy your binary compiled files of your Web API to /api sub-folder. This includes the bin folder, config files, asax files etc - whatever you would need in your local IIS deployment. DO NOT copy the sln/csproj files, otherwise the Azure will also try to do the compilation himself and will change the root of your web application to the folder with csproj files. So, my /api folder looks like this: Web API folder contents

  6. Commit the changes and Git push to azure remote. Once the files are deployed, your SPA app should be up and running. Well done!

  7. You don’t want to copy the files manually all the time, so make a PowerShell script or gulp task to do that for you. Remember, your changes will be applied whenever you push a new version to azure remote of your Git repo.
