Adding Logic to Navigation events

This article describes how developers add logic to navigation events.


Router Hooks allow developers to run Requests, Functions, or Router Function at different points during the routing life-cycle.

A Router Function is almost like a transform on a Resource Request. However, it provides different arguments to the function for the developer to have access to:

// ARGS
// **to**: the Route being navigated to with associated state and params.
// **from**: the Route being navigated away from with associated state and params.
// **state**: the state object local state object.
return function({from, to, state}) {
// type here
}

NOTE: The Router Function’s return value isn’t considered or evaluated.

The following Router Hooks are available at both the Global and Local.

Global

Global router hooks get specified in the Settings > Global Route Hooks of and App Builder project. They run on every Route transition unless the Route.

Configuring Global Hook

The available global hooks are:

  • beforeEach - runs before any Route is entered.
  • afterEach - runs after any Route is entered.

Local

Local router hooks get specified in the Page Settings when editing a specific View. They run only when the associated Route is being navigated.

Configuring Local Hook

The available global hooks are:

  • beforeRouteEnter - runs before the Route is entered.
  • beforeRouteUpdate - runs before the Route is entered. For example, Route /users/:id is changed from /users/20 to /users/83.
  • beforeRouteExitLeave - runs before the Route is left.
