Accessing Links with Multiple Parameters in Angular 15: A Complete Guide

Working with APIs in Angular can be challenging, especially when you need to access endpoints that require multiple parameters. If you've found yourself stuck on how to retrieve an object using such links, you're not alone! In this post, we'll break down a solution for accessing links with multiple parameters in Angular 15, using a real-world example from working with a soccer API.

The Problem

You have an API link structured like this:

In this example:

10 is the Championship ID.

168 is the Stage ID.

Your goal is to access the object located at /168, but first, you have to successfully get the Championship object from the ID /10. This can be confusing if you’re unsure how to manage the parameters in your Angular application.

Understanding the Code Structure

Let’s review the structure of your Angular application based on the provided code snippets.

URLs Configuration

In your urls.ts file, you have configured the base URL and constructed a URL for fetching championship data:

This setup works well; each URL is generated dynamically, making it easy to access specific championships by ID.

Service Methods

You have a service where you define how to fetch data segments:

The issue arises with the getStageById method, where the Championship ID is missing from the URL.

The Solution: Modify and Enhance Your Code

Let’s refine your implementation to properly incorporate the Championship ID when fetching the stage details.

Updating the Service Method

You need to include both stageId and champId in your getStageById method as follows:

Utilizing Activated Route Parameters

You also need to ensure that you're correctly subscribing to parameters in your component to fetch the information accurately:

By calling getStageById(this.stagePhase, params['id']), you’re now passing the correct parameters to access the desired object.

Conclusion

Working with multiple parameters in Angular can be tricky, but with careful structuring of your API calls and routes, you can access the data you need seamlessly. Remember to check your service methods to ensure all necessary parameters are in place for fetching the correct objects.

By following the approach outlined in this guide, you should now be able to confidently navigate and retrieve data from links structured with multiple parameters in Angular 15.

Happy coding!
