React/Node.JS Web App works locally but not in Azure.

Question

My Web App runs locally, but, once deployed to Azure, doesn't.

For example, I am trying to send a POST request to register a new user. Locally, this works perfectly and sends everything to the database, but doing so on the live Web App only returns a 404 error.

How can I resolve this? What do I need to check?

Hello , Welcome to MS Q&A

To effectively monitor the performance of a CDN in Azure Static Web Apps, you can utilize several methods:

Raw Logs: Enable raw logs for your CDN to get detailed information about every request. These logs can be streamed to Azure Storage, Event Hubs, or Azure Log Analytics for further analysis.

Metrics: Azure CDN provides key metrics such as Byte Hit Ratio, Request Count, Response Size, and Total Latency. These metrics help you understand the performance of your CDN.

Alerts: Set up alerts for key metrics to be notified of any performance issues or anomalies.

Azure Log Analytics: Use Azure Log Analytics to enable more metrics and gain deeper insights into your CDN performance.

These tools and features will help you effectively monitor and troubleshoot the performance of your CDN in Azure Static Web Apps. For more detailed guidance, you can refer to the following resources:
