Broken hosting - vite.config.js missing host: true

Hi AspiringDeveloper-0025,

Thank you for your detailed feedback and for sharing your experience with the "Develop locally" path of the tutorial. 

The Microsoft Learn paths, including the tutorial you referenced, are primarily designed to be run on a local machine using Visual Studio Code. The instructions and configurations provided are optimized for this environment. Running the tutorial inside a Docker container, as you have done, introduces some additional considerations that are not covered in the tutorial. 

Regarding your suggestion: 

1.Local Machine Setup: The tutorial assumes that the development environment is set up on a local machine with Visual Studio Code. In this context, the host: true setting is not necessary, as the server is directly accessible on localhost. 

2.Containerized Environment: For users running the development environment inside a Docker container, adding host: true in the vite.config.js file is indeed essential. This setting allows the Vite server to bind to all network interfaces, making it accessible from outside the container. 

To clarify and improve the tutorial, here’s what you can do to run it inside a Docker container: 

Adjusting vite.config.js for Docker: If you are following the "Develop locally" path using a Docker container, you should modify your vite.config.js as follows: 

export default defineConfig({
  server: {
    host: true,
    port: 3000, // or any other port you are using
    proxy: {
      '/api': 'http://localhost:5100' // Example proxy setup
    }
  },
  // other configurations
});

3.Feedback for Tutorial Improvement: Your feedback is very valuable, and I will forward it to the tutorial's maintainers. While the current tutorials are designed for local machine setups, your suggestion to include specific instructions for containerized environments will be considered for future updates. 

Thank you.
