In this section, we shall be looking at the different means of improving Angular application development performance at load time (when the application is loading) and runtime (when the application is in use).
Before you begin optimization, you must run some performance analysis tests, for example, to check the load time, especially on different platforms. Testing is also essential because you cannot improve something if you don't measure it first. Google, for example, has been a top provider of optimization services such as Lighthouse and PageSpeed Insights, used to analyze and optimize your website manually or automatically...
