Side Effects

Explanation

Side effects are observer functions that are run when a new response is created. They are called after other response handlers (observers that were set using router.observe and one time functions that were set using router.once). They receive the new response and an object with information about the navigation.

Side effect functions are registered when creating a router using the sideEffects property of the options object.

import { createRouter } from "@curi/router";
import mySideEffect from './mySideEffect';

let router = createRouter(browser, routes, {
  sideEffects: [mySideEffect]
});
