Send data through routing paths in Angular

Sending Data Through Routing Paths in Angular: A Comprehensive Guide 🚀

👋 Hey there! Are you struggling to send data as a parameter using router.navigate in Angular? Look no further! We've got you covered with easy solutions and helpful tips. Let's dive right in! 💪

The Problem: Invalid Parameter Error ❌

So, you're trying to send data as a parameter using router.navigate and you encounter an error like this:

this.router.navigate(["heroes"], { some-data: "othrData" });

The error message states that some-data is not a valid parameter. How frustrating! But fret not, we have a few workarounds for you to achieve your desired outcome without having to use queryParams.

Solution 1: Utilizing the state Property 🌐

Angular provides a state property within the navigation extras parameter that allows us to send data without relying on queryParams. Let's modify your code using the state property:

this.router.navigate(["heroes"], { state: { someData: "othrData" } });

By using state, you can attach your desired data to the navigation request. Yay! 🎉 But wait, how do we access this data on the target component?

Solution 2: Retrieving Data in the Target Component 🕵️‍♀️

To retrieve the data in the target component, you can access the state property of the ActivatedRoute service. Here's how you can do it:

import { ActivatedRoute } from "@angular/router";

// Inside your component
constructor(private route: ActivatedRoute) {}

ngOnInit() {
  const data = this.route.snapshot.state.someData;
  console.log(data); // Output: "othrData"
}

Voila! 😎 You can now access the passed data in your target component effortlessly. Just make sure to import the ActivatedRoute service and retrieve the data using this.route.snapshot.state.
