vue-pure

This is an example of using Purescript to handle business logic in a Vue application. It uses purs-loader to incorporate Purescript compilation into the webpack build.

Advantages

• All the benefits of static-typing, purity, and controlled effects
• Redux debug tools
• Vue ecosystem and tooling

Setup

The actions, state, and reducers are written in Purescript. They can be found in the state directory. Connecting this to Redux is done in state/store.js:

• Each reducer is applied to uncurryReducer, which catches the initialization case (where state is undefined), by calling the rootReducer with an initialAction.
• standardizeAction intercepts incoming actions to assign them a name (following "flux-standard-action")

Dispatching

Each smart component has a corresponding .purs file that will handle mapping the state and dispatch to props. An example is components/Counter/Counter.purs, where the state and actions are exposed. Action creators are placed in their corresponding Action.purs file and can be invoked inside mapDispatchToProps.

Why not Vuex?

Unfortunately, Vuex is not a good candidate for purescript interop because it depends on mutability. Purescript has no concept of mutability and this would require mapping immutable state updates to the Vuex state. Although not impossible, it does present a performance concern as well as hindering reducer composition.
