The element is implicitly assigned an 'any' type due to the absence of an index signature in the type 'ActivatedRouteSnapshot'

While working on Angular2 routing, I encountered an issue where my dynamically generated links were causing an error after a few seconds. The error message is as follows:

https://i.sstatic.net/6GM06.png

Here is the code snippet for my routerLink:


<a [routerLink]="['category/', electronic.name]" *ngFor="let electronic of electronics ">
  {{electronic.name}}
</a>

And here is the component code:


import { Component, OnInit } from '@angular/core';
import { DatabaseService } from "../../service/database.service";
import { ActivatedRoute } from '@angular/router';

@Component({
  selector: 'app-category-list',
  templateUrl: './category-list.component.html',
  styleUrls: ['./category-list.component.css']
})
export class CategoryListComponent implements OnInit {

  constructor(private database: DatabaseService, private activeRoute: ActivatedRoute) { }

  ngOnInit() {
    let name = this.activeRoute.snapshot['name'];
    console.log(name);
  }

}

Answer №1

The TypeScript compiler is throwing an error on this particular line

let name = this.activeRoute.snapshot['name'];

This issue arises because, according to the Angular documentation, there is no indexer available on the ActivatedRouteSnapshot interface for retrieving information in the way you are attempting. To access data from the object, consider implementing an indexer like so:

interface Example {
    [key:string]: any;
}

Refer to the documentation for guidance on using the object correctly.
