## Background

This is a React port of [rstacruz](https://github.com/rstacruz)'s [`nprogress`](https://github.com/rstacruz/nprogress) module. It exposes an API that encapsulates the logic of `nprogress` and renders nothing, giving you complete control over rendering.

## Usage

In the following examples, `Container`, `Bar` and `Spinner` are custom components. `NProgress` doesn't render anything itself.

**Hook**

```jsx
import { useNProgress } from '@tanem/react-nprogress'
import React from 'react'
import { render } from 'react-dom'
import Bar from './Bar'
import Container from './Container'
import Spinner from './Spinner'

const Progress = ({ isAnimating }) => {
  const { animationDuration, isFinished, progress } = useNProgress({
    isAnimating
  })

  return (
    <Container animationDuration={animationDuration} isFinished={isFinished}>
      <Bar animationDuration={animationDuration} progress={progress} />
      <Spinner />
    </Container>
  )
}

render(<Progress isAnimating />, document.getElementById('root'))
```

**Render Props**

```jsx
import { NProgress } from '@tanem/react-nprogress'
import React from 'react'
import { render } from 'react-dom'
import Bar from './Bar'
import Container from './Container'
import Spinner from './Spinner'

render(
  <NProgress isAnimating>
    {({ animationDuration, isFinished, progress }) => (
      <Container animationDuration={animationDuration} isFinished={isFinished}>
        <Bar animationDuration={animationDuration} progress={progress} />
        <Spinner />
      </Container>
    )}
  </NProgress>,
  document.getElementById('root')
)
```

**HOC**

```jsx
import { withNProgress } from '@tanem/react-nprogress'
import React from 'react'
import { render } from 'react-dom'
import Bar from './Bar'
import Container from './Container'
import Spinner from './Spinner'

const Inner = ({ animationDuration, isFinished, progress }) => (
  <Container animationDuration={animationDuration} isFinished={isFinished}>
    <Bar animationDuration={animationDuration} progress={progress} />
    <Spinner />
  </Container>
)

const Enhanced = withNProgress(Inner)

render(<Enhanced isAnimating />, document.getElementById('root'))
```

## API

**Props**

- `animationDuration` - _Optional_ Number indicating the animation duration in `ms`. Defaults to `200`.
- `incrementDuration` - _Optional_ Number indicating the length of time between progress bar increments in `ms`. Defaults to `800`.
- `isAnimating` - _Optional_ Boolean indicating if the progress bar is animating. Defaults to `false`.
- `minimum` - _Optional_ Number between `0` and `1` indicating the minimum value of the progress bar. Defaults to `0.08`.

**Hook Example**

```jsx
const Progress = ({
  animationDuration,
  incrementDuration,
  isAnimating,
  minimum
}) => {
  const { isFinished, progress } = useNProgress({
    animationDuration,
    incrementDuration,
    isAnimating,
    minimum
  })

  return (
    <Container animationDuration={animationDuration} isFinished={isFinished}>
      <Bar animationDuration={animationDuration} progress={progress} />
      <Spinner />
    </Container>
  )
}

<Progress
  animationDuration={300}
  incrementDuration={500}
  isAnimating
  minimum={0.1}
/>
```

**Render Props Example**

```jsx
<NProgress
  animationDuration={300}
  incrementDuration={500}
  isAnimating
  minimum={0.1}
>
  {({ animationDuration, isFinished, progress }) => (
    <Container animationDuration={animationDuration} isFinished={isFinished}>
      <Bar animationDuration={animationDuration} progress={progress} />
      <Spinner />
    </Container>
  )}
</NProgress>
```

**HOC Example**

```jsx
const Inner = ({ animationDuration, isFinished, progress }) => (
  <Container animationDuration={animationDuration} isFinished={isFinished}>
    <Bar animationDuration={animationDuration} progress={progress} />
    <Spinner />
  </Container>
)

const Enhanced = withNProgress(Inner)

<Enhanced
  animationDuration={300}
  incrementDuration={500}
  isAnimating
  minimum={0.1}
/>
```
