Imagine a scenario: a junior developer comes to you with a task to create an Angular component with a field to display a token and a 'create token' button. When the button is pressed, a request is sent to the server, a token is received, and the junior writes this.token = the received string, but the value is not displayed and the page does not re-render. What would you advise to solve this problem and what approaches are generally available to fix it?

Continuation of the scenario with a junior: after your comment about the lack of error handling, the junior added a catchError method to the pipe, which in case of an error places the message 'error receiving token' into the same token signal where the token itself was previously stored. Analyze this approach from the perspective of responsibility mixing - what is done wrong here and how would you explain it from the architectural principles (particularly, Single Responsibility Principle and separation of presentation and model)?

Do you agree with the thesis that a universal shared component, which appears in different parts of an application, and a library component intended for import into other applications are not the same, and that their approaches should be different? What requirements would you impose on a library component as opposed to a shared component?
