# polite-element [![stability][0]][1]
[![npm version][2]][3] [![build status][4]][5]
[![downloads][8]][9] [![js-standard-style][10]][11]

Politely waits to render an element until the browser has time to spare using
[window.requestIdleCallback()][idle]. Useful to create incrementally loading
applications that don't block user interaction.

## Usage
```js
var polite = require('polite-element')
var html = require('bel')

var main = html`
  <main>
    ${polite(renderBasic, renderFancy)()}
  </main>
`
document.body.appendChild(main)

function renderBasic () {
  return html`
    <img alt="ms. floof" />
  `
}

function renderFancy () {
  return html`
    <img src="https://cool-cat.pix/meow" alt="ms. floof" />
  `
}
```

## API
### el = politeElement(renderBasic, renderFancy)
Create an initial element on load using `renderBasic`. Once the browser [is less
busy][idle] it will call the `renderFancy` function to load a more complex
element. Always calls `renderBasic` when run in Node.

## Installation
```sh
$ npm install polite-element
```
