Understanding Angular Routing Issues with Multiple Routes in a Module

In developing Angular applications, one common issue developers encounter is when routing does not behave as expected, particularly when multiple routes are defined within a module. If you're facing a situation where only the first route works and subsequent routes redirect you back to the first one, you’re not alone. Let's dive into the problem, and more importantly, the solution.

The Problem

You have defined multiple components in a module that each in turn has its own route. However, when you attempt to navigate to URLs intended for the second component, the application redirects you back to the first route instead. Here's the routing configuration that illustrates the issue:

The app-routing configuration that loads the module is as follows:

Key Routes

Navigating to foo/first works fine.

Navigating to foo/second redirects you back to foo/first.

You also attempted adjustments such as altering the paths, but they did not resolve the issue.

The Solution

The problem lies in how the routes are defined in the FooRoutingModule. The current setup doesn't correctly account for child routes under the parent path foo. Here’s how you can fix it:

Step-by-Step Route Configuration

You need to properly configure the routes in foo-routing.module.ts to utilize child routes effectively. Here’s the revised routing configuration:

Important Points

Use redirectTo at the proper level: The redirectTo path should not include the parent path when you specify it under a module since Angular will already prepend foo/.

Define each route distinctly: Make sure that each route component (in this case, FirstComponent and SecondComponent) is clearly defined without nesting the paths implicitly under the current one.

Results

After making these changes, navigating to:

foo/first: This should direct correctly to the FirstComponent.

foo/second: This should now correctly navigate to the SecondComponent without redirecting back to first.

Conclusion

By ensuring distinct route configurations and correctly using redirections, you can effectively navigate between multiple components in a single module using Angular routing. This structural clarity not only helps in troubleshooting issues but also aids in scaling your application in the future. Happy coding!
