In Angular single-page applications (SPA), dynamically modifying meta tags directly through client-side JavaScript is generally ineffective for search engine crawlers and social media scrapers, because most of them do not execute JavaScript and only read the initial HTML. To achieve page-level dynamic SEO and social media sharing information, server-side rendering (SSR) must be used. Angular Universal is the officially recommended solution. It can pre-render page content on the server side, including dynamic meta tags, to ensure that crawlers can index it correctly.

This article proposes two effective solutions to the redundant problem caused by a large number of variable declarations of the same type in PHP class constructors. First, by grouping related properties into separate objects, you can simplify the parameter list of the constructor, making the code more readable and maintainable. Secondly, the UserBuilder pattern is introduced, allowing objects to be built incrementally and handling optional parameters, thereby further reducing the complexity of the constructor. In addition, the importance of re-evaluating class design is emphasized to avoid classes taking on too many responsibilities.
