#### Nothing to see here ...

Quite so. This package allows you to bring React's high-level component abstraction to Node or wherever you need it. Why not manage your REST endpoints like routes on the client, users as components with mount/unmount lifecycles, self-contained separation of concern, and clean side effects? Suspense for requests, etc.

You can try a small demo here: https://codesandbox.io/s/react-nil-mvpry

#### How does it work?

The following renders a logical component without a view, it renders nothing, but it has a real lifecycle and is managed by React regardless.

```jsx

import * as React from 'react'

import { render } from 'react-nil'

function Foo() {

  const [active, set] = React.useState(false)

  React.useEffect(() => void setInterval(() => set((a) => !a), 1000), [])

  // false, true, ...

  console.log(active)

}

render()

```

We can take this further by rendering made-up elements that get returned as a reactive JSON tree from `render`.

You can take a snapshot for testing via `act` which will wait for effects and suspense to finish.

```jsx

import * as React from 'react'

import { act, render } from 'react-nil'

function Test(props) {

  const [value, setValue] = React.useState(-1)

  React.useEffect(() => setValue(Date.now()), [])

  return 

}

const container = await act(async () => render())

// { type: 'timestamp', props: { value: number }, children: [] }

console.log(container.head)

```
