Redux Devtools Extension
Redux DevTools displays the global state of the application and lets developers drill down to look into every object. There is also a corresponding actions list that tracks all actions that have occurred, so developers can see how actions and the state are interacting. This chrome extension makes the components and providers of your Angular application accessible on click on an element in the Chrome DevTools elements panel.

We’ve already gone over the Angular Devtools profiler, but there is another tool provided by Angular that we can use for identifying performance issues related to change detection.
It allows for quick inspection of the piece of code being executed and the values of all variables at that moment in time. Developers may be logging messages using console.log() to inspect the value of some variable or simply ensure their code is executing in the right order. Warnings and the majority of runtime errors get also printed here. List all modules that the application is using and check their providers and exports.
