Helpful re-frame events for manipulating and fetching store data

API Overview

morley.core/get

Read a value from db by k, not-found or nil if value not present.

(morley.core/get :my-store-key)

morley.core/get-in

Read a value from db by path, not-found or nil if value not present.

(morley.core/get-in [:my-store-key :nested-key])

morley.core/assoc

Applies assoc to app-db with args.

(morley.core/assoc :my-store-key {:my "cool new value"})

morley.core/assoc-in

Applies assoc-in to app-db with args.

(morley.core/assoc-in [:my-store-key :nested-key] {:my "cool new value"})

morley.core/update

Applies update to app-db with args.

(morley.core/update :my-store-key inc)

morley.core/update-in

Applies update-in to app-db with args.

(morley.core/update-in [:my-store-key :nested-key] inc)

morley.core/dissoc

Applies dissoc to app-db with args.

(morley.core/dissoc :my-store-key)

morley.core/dissoc-in

Applies dissoc-in to app-db with args.

(morley.core/dissoc-in [:my-store-key :nested-key] :some-key)

morley.core/reset

Clears the store. Useful for testing.

(morley.core/reset)

morley.core/watch

Allows you to pass a get or get-in value instead of a full subscription, so that it feels more like all the other utils.

(morley.core/watch [:my-store-key :nested-key] (fn [_] (do-something)))

morley.core/watch-sub

Given a subscription, call on-change-fn when it changes, passing the old-value and the new-value. Returns an unwatch function for cleanup. This is basically a convenience function around add-watch/remove-watch on re-frame subscriptions.

(morley.core/watch-sub (rf/subscribe [:my-subscription])
                       (fn [old new] (do-something)))

morley.core/local-storage

A re-frame interceptor that, after an event, will persist to local storage anything in the app-db that exists under the :local-storage key. If the :sync-before flag is passed, the interceptor will read from local storage and reset the value at the :local-storage key to what was read before running the event handler. This is applied to any Morley 'change' function

(morley.core/assoc-in [:local-storage :nested-key] {:my "value"})
