Added support for Firebase Storage & Firebase Functions

[wkok]

Thank you for this library, I find it extremely useful.

Currently you have wrappers for Firebase Authentication, Realtime Database & FireStore

I thought it useful to include basic operations of Firebase Storage and Firebase Functions submitted via this Pull Request.

Storage

re-frame effects are implemented for basic Storage functions put, delete & download-url

Put

Puts a collection of File objects into a Firebase Storage bucket.
See: https://firebase.google.com/docs/storage/web/upload-files

Required arguments :path :file

• :path Path to object in the Storage bucket
• :file File (https://developer.mozilla.org/en-US/docs/Web/API/File)
• :bucket If not supplied, will assume the default Firebase allocated bucket
• :metadata Map of metadata to set on Storage object
• :on-progress Will be provided with the percentage complete
• :on-success
• :on-error

Example FX:

   {:storage/put [{:path "path/to/object"
                   :file File
                   :metadata {:customMetadata {"some-key" "some-value"}}
                   :on-progress #(.log js/console (str "Upload is " % "% complete."))
                   :on-success #(js/alert "Success!")
                   :on-error #(js/alert "Error: " %)}]}

Delete

Deletes a collection of object paths/keys from a Firebase Storage bucket.
See: https://firebase.google.com/docs/storage/web/delete-files

Required arguments :path

• :path Path to object in the Storage bucket
• :bucket If not supplied, will assume the default Firebase allocated bucket
• :on-success
• :on-error

Example FX:

  {:storage/delete [{:path "path/to/object"
                     :on-success #(js/alert "Success!")
                     :on-error #(js/alert "Error: " %)}]}

Download URL

Generates a url with which the browser can download an object from Firebase Storage
See: https://firebase.google.com/docs/storage/web/download-files

Required arguments: :path

• :path Path to object in the Storage bucket
• :bucket If not supplied, will assume the default Firebase allocated bucket
• :on-success Will be provided with the download url
• :on-error

Example FX:

  {:storage/download-url {:path "path/to/object"
                          :on-success #(js/window.open %)
                          :on-error #(js/alert "Error: " %)}}

Functions

re-frame effects are implemented for basic Functions of call

Call

Executes a Callable Firebase Cloud Function
See: https://firebase.google.com/docs/functions/callable

Required arguments: :cfn-name :data

• :cfn-name Cloud Function name
• :data Map containing request data
• :on-success Will be called with a clojure Map containing the response data
• :on-error

Example FX:

  {:functions/call {:cfn-name "my-function-name"
                    :data {:foo "bar"} 
                    :on-success #(js/alert (:foobar %))
                    :on-error #(js/alert "Error: " %)}}
