1.1.2 (2020-11-11)

Added

  • Add a new interceptor called unwrap. It decreases the amount of destructuring necessary in an event handler where the event is structured as a 2-vector of [event-id payload-map]. Implemented as the outcome of #644.

Changed

  • The :coeffects map (within context) will now contain a new key called :original-event which has as its value the original event dispatched, prior to any modification by interceptors such as trim-v and unwrap. To this another way, the coeffects map will have BOTH an :event and an :original-event key, which will reference the original event dispatched UNLESS interceptors have modified :event
  • The trim-v interceptor now produces a warning if event is not a vector. Just in case someone has mixed the use of trim-v and unwrap together. The trim-v interceptor will not modify an event if it is not a vector.

Breaking

  • Previously, the trim-v interceptor stored the original event (prior to any modification) within coeffects using the key :re-frame.std-interceptors/untrimmed-event. But, now, trim-v no longer does this. Any code relying on this implementation detail will now break. Instead, you should access the event stored in the :original-event key, as described above.

Fixed

  • Fix reg-global-interceptor code reloading by replacing interceptors with duplicate ids in place to maintain the ordering of global interceptors. Previously would result in the interceptor actually being duplicated. See #655
  • Fix event handlers passing events modified by interceptors to tracing, instead all event handlers now use :original-event for tracing.

1.1.1 (2020-08-26)

Added

  • The built-in effect :dispatch-later can now take a single map value. Supplying a sequence of maps is now deprecated in favour of using multiple :dispatch-later effects within the new :fx effect. See the API documentation.

1.1.0 (2020-08-24)

Added

  • re-frame now guarantees that a :db effect, if present, will be actioned before any other sibling effects. re-frame continues to provide no guarantees about the order in which other effects will be actioned.

  • Added an new :fx built-in effect handler. Previously, you might have returned effects like this:

    1
2
3
4
5
6
7
8
9
    (reg-event-fx 
  :token 
  (fn [{:keys [db]} [_ id]]
    {:db (assoc db :twirly true) 
     :dispatch [:blah]
     :full-screen true
     :http  (list 
              {:method :GET :url "http://abc.com/endpoint" ...}
              {:method :POST :url "http://blah.com/endpoint" ...})}))

    but now, using :fx:

     1
 2
 3
 4
 5
 6
 7
 8
 9
10
    (reg-event-fx 
  :token 
  (fn [{:keys [db]} [_ id]]
    {:db (assoc db :twirly true) 
     :fx [ [:dispatch     [:blah]] 
           [:full-screen  true]
           [:http         {:method :GET :url "http://abc.com/endpoint" ...}]
           [:http         {:method :POST :url "http://blah.com/endpoint" ...}]

           (when seventies? [:hair "side burns"])]     ;; nils are ignored

    Notes:

    • the effect :fx will be associated with a seq, typically a vector
    • the effects in :fx will be actioned in seq order
    • each element in the seq should be a 2-vector. This vector will contain an effect-id, typically a keyword, and an effect payload.
    • if any element of :fx is nil, it will be ignored. This allows effects to be conditionally included via a when (an example is given above)
    • :db effects should not be put into :fx. re-frame will emit a warning if it finds one.

    Benefits:

    • :fx allows for effects to be ordered
    • you can include the same kind of effect multiple times (eg :dispatch) which means there is no longer any need for special effects like :dispatch-n. Indeed, all *-n style effects are now redundant.

    • this feature is a stepping stone towards making it easier to create an event handler which is a composition of other functions. We imagine circumstances in the future in which event handlers might be written more like this:

      #!clj (reg-event-xxxx ;; <-- a new kind of registration function :event-id
      interceptors [function1 function2 function3])

    See exploratory discussion here and here

    This new effect is described in the API docs. Further discussion on its introduction can be found in issue #639.

Changed

  • if your reg-event-fx handler returns an effect map containing an unknown effect key, re-frame will now produce a warning, not a hard error. See #639.
