We've just released v0.9.0 of the Azure Static Web Apps extension for VS Code. This release includes features to help debug your static web app locally, including Azure Functions API routes, authentication, and routing.
If you're new to Azure Static Web Apps, I highly recommend checking out the What is Azure Static Web Apps? documentation page.
In this post, we'll learn how to get started debugging a static web app locally. Then we'll add an Azure Functions API route, and debug our backend + frontend together.
Prerequisites 🛠️
Google Chrome installed, (we make use of the debugger)
Azure Static Web Apps extension for VS Code - View on Marketplace
Azure Static Web Apps CLI 0.8.0 or greater - View on GitHub
npm install -g @azure/static-web-apps-cli@latest
Getting started 🟢
- Clone one of these repositories, and open it up in VS Code.
| Framework | Repository |
|---|---|
| Angular | https://github.com/staticwebdev/angular-basic |
| React | https://github.com/staticwebdev/react-basic |
| Svelte | https://github.com/staticwebdev/svelte-basic |
| Vue | https://github.com/staticwebdev/vue-basic |
- Run
npm install
Run and debug 🐞
- Go to the "Run and Debug" view.
- Click "Show all automatic debug configurations."
- In the dropdown, select "Azure Static Web Apps...".
- Select the app you want to debug.
This will start the Azure Static Web Apps CLI in the VS Code terminal, and launch the Chrome debugger on http://localhost:4280.
Now you can set and hit breakpoints in your frontend code.
Add an API route ⚡️
Azure Static Web Apps has integrated API support provided by Azure Functions. In order to add and debug an API route, we must install some Azure Functions tools.
Azure Functions extension for VS Code - Install from Marketplace
Azure Functions Core Tools - View on GitHub
npm i -g azure-functions-core-tools@3 --unsafe-perm true
Now, you can add an API route to your app by clicking the "Add HTTP Function..." button in the Azure Static Web Apps view.
Select a language (I chose JavaScript), then name your Function (I put "hello"). And then an API route will be created for you that you can make requests to at /api/hello.
Debug app with Functions API ✨
We can debug our API routes and our frontend app simultaneously in VS Code.
Select the "SWA: Run ..." debug configuration and click the green "Run and debug" button.
VS Code will now run your Functions API routes and your frontend. When it's all started, a Chrome window will open at http://localhost:4280.
Set a breakpoint in your Function endpoint.
Go to http://localhost:4280/api/hello in the Chrome window to hit the breakpoint.
Next steps 🏃♀️
Now that you got your static web app running locally, you can deploy your static web app to Azure for free.

This is awesome! I'm sure this will make my next project even easier. 🙌
That's great to hear Daniel!
Hey!! Great article!!! I am a student and I really like the IT field and I try to follow the news. But because of this, there is a catastrophic lack of time for study. especially in term paper writing. My friends advised me the service EduGeeks. Here is their website edugeeksclub.com/buy-thesis/. The guys helped me a lot and plus they did it very professionally and efficiently.
I tried this with Vue and when I set a breakpoint in the App.vue it just says "unbound breakpoint" and will not pause the debugger. Does it work for you?
It looks like there are some issues with debugging Vue.js in VS Code due to how Vue.js generates source maps.
There is a snippet about that here on the VS Code docs:
code.visualstudio.com/docs/nodejs/...
Debugging works for me, however I have to set breakpoints from the Chrome devtools, which is not the best experience.
You could also try this VS Code Vue.js debugging recipe:

I've created an issue on our repository:
github.com/microsoft/vscode-azures...
Feel free to add more details/input on that issue.
I created a vue.config.js and put the following in it:
And it kind of worked, breakpoints worked but they would only be created at the end of methods. So definitely seems to be a source maps issue.
Thanks for the reply!
Sorry about that! It seems like a source map issue. I'm looking into it now.
