+## WebSPA project doesn't come up on debug mode in Visual Studio 2019
+
+Scenario: If you hit F5 to debug the `WebSPA` project of `eShopOnContainers` app, you'll notice that the `WebSPA` application is not reachable when you try to browse the app using `http://<url>:5104/`. It can be worked around by following the below steps:
+
+1. Update Docker file:
+
+- Go to the *eShopOnContainers\src\Web\WebSPA\Dockerfile*
+- Add the below commands just after the line `WORKDIR /app`
+  
+  ```bash  
+  RUN apt-get update
+  RUN apt-get -y install curl gnupg
+  RUN curl -sL https://deb.nodesource.com/setup_10.x | bash -
+  RUN apt-get -y install nodejs
+  RUN npm install
+  RUN npm -v
+  ```
+

+
+1. Update environment variable in the *docker-compose.override.yml* file.
+   
+- For the `webspa` service, change the value of `ASPNETCORE_ENVIRONMENT` variable from `Production` to `Development` just like as per below:
+
+  ```bash
+  - ASPNETCORE_ENVIRONMENT=Development
+  ```
