nanoparts
Emit render for specific parts of the DOM.
Gives you more control over what to re-render on emit('render') with emit('renderPart', 'somePart'), so the update can be done faster.
Basically, it just connects emit('renderPart', id) to state.cache(Nanopart, id), giving a quick way to use simple Nanocomponents. It lives somewhere between a render function and a stateful component.
Installation
npm i nanopartsUsage
var choo = require('choo')
var html = require('choo/html')
var nanoparts = require('nanoparts')
var app = choo()
app.use(nanoparts())
app.route('*', function (state, emit) {
return html`
<body>
${state.nanopart('header', () => html`
<div>
header ${state.count}
</div>
`)}
<div>
body ${state.count}
</div>
</body>
`
})Then later call emitter.emit(state.events.RENDER_PART, 'header') to re-render only the header.
API
nanoparts()
Initializes the store and applies events. Adds the nanopart function to the state.
state.nanopart(id, renderer, opts)
Renders and caches a new part with id and returns renderer(state, emit). Pass shouldUpdate: false in the options to don't update the part on normal DOM updates.
emitter.emit('renderPart', id)
Triggers the re-render of part id.
