Router Lifecycle event ResolveEnd in Angular | Angular tutorial in Hindi (Session-226)
In this Angular session, learn everything about the ResolveEnd event — the Router Lifecycle event that fires when Angular completes executing all route resolvers. This event helps you understand when pre-fetched data is fully loaded, when navigation can safely proceed, and how to debug resolver performance, API delays, and data-flow issues in real Angular applications.
What You’ll Learn in This Video:
1.What is ResolveEnd event in Angular
2.When ResolveEnd is triggered during Router Lifecycle
3.How Angular completes resolver execution
4.How to subscribe to ResolveEnd event in Angular
5.Use cases of ResolveEnd in real Angular applications
6.Difference between ResolveStart and ResolveEnd
7.Best practices for using route resolvers and ResolveEnd event
Concept Breakdown:
🔹 End of Resolver Execution: ResolveEnd fires when all resolvers for the target route have finished running.
🔹 Data Ready State: Indicates that all required data is fetched and the route can now be activated safely.
🔹 API Performance Monitoring: Helps track slow, failed, or delayed resolver API calls.
🔹 Debugging Tool: Useful for diagnosing why a route takes too long to load or fails to activate.
🔹 Resolver Output: Event object contains resolved data, route snapshot, and resolver completion status.
🔹 UX Optimization: Helps ensure that components receive fully prepared data at the right time.
