State management lib for choo ✌️. Experiment for now. Might become part of
choo at some point, who knows.
const Model = require('choo-model')
const mount = require('choo/mount')
const html = require('choo/html')
const choo = require('choo')
const app = choo()
app.model(todosModel())
app.router(['/', mainView ])
mount('body', app.start())
function todosModel () {
const model = Model('todos')
model.state({ todos: [] })
model.reducer('add', (state, data) => state.push({ text: data }))
return model.start()
}
function mainView (state, prev, send) {
return html`
<body>
<main><p>Todos: ${state.todos}</p></main>
</body>
`
}Create a new model instance
Return the model object, ready for the app.model() call.
Create a new reducer
Save new state. The resulting state is combined into a single state object under the hood.
Create a new subscription
Create a new effect

$ npm install choo-modelBecause experimenting outside of core is the right way to do things.
Probably the ability to set constraints on send() calls so they can't access
everything. Also the ability to create graph data based on those constraints.
Perhaps selectors too. Y'know, basic stuff.
Having a solid story for state management is quite important. Some abstractions start to break down once apps grow; we're hitting that point. Everything else is irrelevant if we can't scale and use it ourselves on real projects.
Try it out. Build things on top of it. Build out alternatives.
Yeah, definitely - if this ever makes the cut we can statically analyze the code and precompile the result so it'll have no overhead at runtime. Yay!
