Aurelia: Getting the route template from child routers in a parent routers pipeline step

To track page views I needed a way to get the route templates from my child routes. The Problem: I wanted to get them in a pipline step from my parent router.

After some time trying I came up with solution to the problem. The code is quite simple:

import { NavigationInstruction } from "aurelia-router";

export function getRouteTemplateName(instruction: NavigationInstruction): string {
    let instructions = instruction.getAllInstructions();
    let route = "";
    for (const instruction of instructions) {
        let routeConfig = instruction.config.route;
           if (typeof routeConfig === "string")
           route += routeConfig.replace("*childRoute", "");
    return route;

You can use the function like so:

import { PipelineStep, NavigationInstruction, Next } from "aurelia-router";
import { getRouteTemplateName } from "./routeNameFilter";

export class PreActivateStep implements PipelineStep {
    run(instruction: NavigationInstruction, next: Next) {
        return next();

I hope you will find it usefull :)
