[Angular integration] [ReferenceError: document is not defined]

[Mohamed_Hegazy]

Describe the bug

When attempting to use server-side rendering (SSR) with Angular and Vite, an error occurs during the evaluation of the server-side rendering module (main.server.mjs). The error is a ReferenceError, stating that document is not defined.

Expected behavior

The application should render without errors during server-side rendering.

Actual behavior

A ReferenceError occurs during the evaluation of the server-side rendering module, specifically related to the document object not being defined.

Hi @MohamedAsaad1, consider importing tw-elements package dynamically. By doing it, you can enhance the initialization process, potentially resolving any issues related to component functionality. Additionally, ensure that the initTE() method is called in the correct sequence and with the appropriate parameters, facilitating a smoother experience with TWE components. For more information, check out our Angular Integration tutorial - there is a Troubleshooting section, which will help you with solving common issues.

Try using the autoReinits option in initTE method. By default, its value is set to false. By changing the value to true, the initTE method won't check if components were already initialized.
