> [lit](https://lit.dev/) with pure functions.

## Install

`npm install pure-lit`

or add it to your page as module like this:

``

## Getting started

[![pure-lit.org](docs/img/documentation-button.png)](https://pure-lit.org)

The quickest way of getting started is by using JavaScript modules.

Create a file `index.html` that looks like this:

```html

  

    

    Awesome pure-lit

    

      import { html } from "https://unpkg.com/lit@latest?module";

      import { pureLit } from "https://unpkg.com/pure-lit@latest?module";

      pureLit(

        "hello-you",

        async ({ who }) => {

          return html`<div>Hello ${who}!</div>`;

        },

        {

          defaults: { who: "" },

        }

      );

    

  

  

    

  

```

Open it in the browser. Done.

## Adding some state 

pureLit exports the hooks from [lit-element-state-decoupler](https://github.com/MatthiasKainer/lit-element-state-decoupler) and [lit-element-effect](https://github.com/MatthiasKainer/lit-element-effect) which you can use to manage your state inside the functional components.

You can import them via

```typescript

import { pureLit, useState, useReducer, useWorkflow, useEffect, useOnce } from "pure-lit";

```

and then use them like this:

```typescript

pureLit("hello-world", (element) => {

    const counter = useState(element, 0);

    return html` counter.set(counter.get() + 1)}">You clicked me ${counter.get()} times!`

});

```
