Errors in the logs during the Angular SSR (Server-Side Rendering)

 

1. Error Handling: If there are errors that aren't properly handled, it can cause delays during the server-side rendering process. The server might be spending additional time trying to process and recover from errors, which can increase the initial load time.

2. Unoptimized Bundles: Some errors might indicate issues with the Angular build configuration, like improperly optimized assets or missing lazy-loaded modules. This could result in larger JavaScript bundles or resources being served, which would increase load time for the user.

3. Failed Server-side Rendering: If certain components or services fail to render on the server, it might fall back to client-side rendering, which can delay the first meaningful paint (FMP) and increase load time.

4. Resource Fetching: Errors related to data fetching during SSR (e.g., API calls) might also impact how quickly the page loads. For instance, if the server is waiting for data that is not fetched successfully, it may delay the page rendering.

5. Client-Side Hydration: If the SSR is not working correctly, it might impact the client-side hydration process, causing re-renders or increased JavaScript execution time, which will affect the loading performance.

Observations You Should Make:

• Check for Critical Errors: Identify if the errors are blocking the SSR process or causing fallback to CSR (client-side rendering). Errors in fetching data or rendering can significantly slow down the page load.
• Performance Profiling: Run a performance profiling tool (e.g., Chrome DevTools, Lighthouse) to observe the impact of these errors on the overall loading performance.
• Analyze Logs: If the errors are related to missing dependencies or improperly bundled assets, fixing these can directly improve performance.

Suggested Actions:

• Fix the Errors: Resolve the errors, especially if they’re related to missing or incorrect configurations. Pay attention to modules, services, and assets that might be improperly bundled.
• Optimize SSR: Ensure that your SSR setup is properly optimized, and the page is rendered as efficiently as possible on the server.
• Use Lazy Loading: Ensure that Angular modules are lazily loaded where applicable to reduce the size of the initial bundle.
