How to send params in a programmatic navigation in sveltekit?

I want to use programmatic navigation in sveltekit, sending in the same time params to the route I want to navigate to. I know there is the goto method that I can use for programmatic navigation but I can't use it to also send params in navigation.

For example in vue js, it can be done like this:

router.push({ name: 'user', params: { userId: '123' } })

How can this be done in sveltekit?

Thank you!

Indeed $app/navigation is used for programmatic navigation, but it only accepts a string.
To create a string from params you can use a URLSearchParams object.

I've created a small utility function to generate the urls ( REPL ):

export default function buildUrl(path, params) {
  const query = { ...params };
  let interpolatedPath = path;
  for (const [param, value] of Object.entries(params)) {
    const replaced = interpolatedPath.replace(`[${param}]`, value);
    if (replaced !== interpolatedPath) {
      interpolatedPath = replaced;
      delete query[param];
    }
  }
  const search = new URLSearchParams(query).toString();
  return `${interpolatedPath}${search ? `?${search}` : ""}`;
}

Usage:

import { goto } from "$app/navigation";

const url = buildUrl('/users/[user]', {user: 123, tab: 'settings'}));
goto(url); // "/users/123?tab=settings"

You can navigate via goto/href with url search params and then parse these parameters in load function.

`/your_route/?name=${userName}&id=${userId}`
