Sweet Tooth Frontend

Just as an operating system provides resources like the filesystem to address needs that are not specific to any particular application, The Sweet Tooth Frontend framework aims to address many common needs that single page apps have in common.

The library is a layer on top of re-frame, providing handlers, subscriptions, components, utilities and conventions to give you a sane, extensible starting point to deal with:

• API calls
  • performing calls
  • sharing routes between frontend and backend
  • keeping track of active calls (e.g. to show activity indicators)
  • call lifecycle
• Forms
  • storing their data in the app db
  • validation
  • the submission lifecycle
  • components that "wirte things up" so you don't have to.
• URL-based navigation with HTML history
• Pagination

API calls with sync

• helpers

Transform various calls into a dispatch on ::sync or ::sync-once. Those dispatches take a req.

• sync signature

• sync-fx handler signature

(defn sync-fx
  "Returns an effect handler that dispatches a sync event"
  [[method endpoint opts]]
  (fn [_cofx [call-opts params]]
    {:dispatch [::sync [method endpoint (build-opts opts call-opts params)]]}))

(fn [_cofx [call-opts params]]
    {:dispatch [::sync [method endpoint (build-opts opts call-opts params)]]})

• calling directly
• building handlers
• default callbacks
• :$ctx
• subscriptions

Forms

Sweet Tooth eliminates much of the boilerplate for creating forms.

• structure
• concepts

with-form

• the form "name"
  • used for storing form state
  • used for sync
• inputs
• fields
• submission
  • syncing
  • lifecycle / state that gets updated
  • what gets submitted - extra data

Validation

success

fail
