com.fulcrologic.fulcro.routing.dynamic-routing

A router that uses Fulcro dynamic queries to optimize query performance on rendering and provides a number of useful features such as easy composition, control over route targeting, on-screen component vetoes of routing requests, etc.

NOTE: This router is not concerned with HTML5 history events or URL management. This router is intended to be usable in server-side rendering, React Native, and anywhere else Fulcro might be used. Therefore it is not tied to a particular rendering platform's idea of location management (i.e. URLs).

The structure of the route composition (and its representation as a sequence of string path components) is intended to be easy to integrate with HTML5 history and URL control.

active-routesclj/s

(active-routes app)
(active-routes app starting-from)

Return a sequence of the leaf router targets that are routed to in the given app using the active dynamic query and app state.

The return values are maps that currently contain a :path and :target-component key. Future versions of this function may include additional information.

Note that dynamic routing purposely supports the ability to have more than one UI path active at a time, as it is NOT a strict URL-style UI router. However, since your code is ultimately responsible for determining what parts of the active query are rendered, it is possible for this to return routes that are available (in the props of components) but are not being rendered by your logic. Thus, the return value of this function isn't necessarily proof that the routes listed are visible to the user.

WARNING: If you use disconnected roots (via hooks or otherwise), then you must specify a starting component that is well-connected (graph/state) from which to scan, and will get back paths relative to that starting-from (a component, element, or factory if you're using factory-based dynamic queries).

The options are:

:router-targets - (REQUIRED) A vector of ui components that are router targets. The first one is considered the "default" (purely for the purpose of initial state; you always need to explicitly route to a particular target). Other defsc options - (LIMITED) You may not specify query/initial-state/protocols/ident, but you can define things like react lifecycle methods. See defsc. :always-render-body? - (OPTIONAL) When true this router expects that you will supply a render body, and it will always be rendered. The props available in the body will include:

  • :current-state - The state of the routing state machine. (:initial, :pending, :failed, :routed)
  • :route-factory - A factory that can generate the current route.
  • :route-props - The props that should be passed to the route factory. You can augment these with computed if you wish. The router normally passes computed through like so: (route-factory (comp/computed route-props (comp/get-computed this)))
  • :pending-path-segment - The route that we're going to (when in pending state).
  • :router-state - A map of the path management details of the router. Includes the pending path segment (if deferred), the target, and the path segment of the current route.

The optional body, if defined, will only be used if the router has the :always-render-body? option set or it is in one of the following states:

  • :pending - A deferred route is taking longer than expected (configurable timeout, default 100ms)

evaluate-relative-pathclj/s

(evaluate-relative-path relative-instance new-route)

Takes an on-screen instance of a react element and a new route (vector of strings) and returns a vector containing either the original arguments, or an evaluation of relative navigation up the live routing tree.

If new-route starts with :.. (any number of times) then this function finds (and returns) the parent router and the new route stripped of :.. prefix.

For example, say you were in a target instance that has a parent router, which in turn has a parent router called SomeRouter. Then:

(dr/evaluate-relative-path this [:.. :.. "some-target"])
=> [SomeRouter ["some-target"]]

This function does not work on classes. It is meant for live evaluation of on-screen instances to enable relative routing based on the actual on-screen route targets.

CAN return nil for the router if no such parent is found.

Returns unmodified input argument if new-route does not begin with :...
