        # hx

[![Clojars Project](https://img.shields.io/clojars/v/lilactown/hx.svg)](https://clojars.org/lilactown/hx)

A simple, easy to use library for React development in ClojureScript.

## Update - Transfer of ownership

The [original author](https://github.com/lilactown) has kindly agreed to transfer ownership of this project to Nosco. We're using hx in production and don't expect any breaking changes, but we are fixing small issues and minor quality of life improvements as we find them. 

Development from the [original author](https://github.com/lilactown) has moved to [helix](https://github.com/lilactown/helix). Helix is the latest version of hx, with some breaking changes (no hiccup parser, slightly different hooks API, and a focus on compile-time semantics).

## Example

```clojure

(ns my-app.core

  (:require [hx.react :as hx :refer [defnc]]

            [hx.hooks :as hooks]

            ["react-dom" :as react-dom]))

;; `defnc` creates a function that takes a props object and returns React

;; elements. You may use it just like any normal React component.

(defnc MyComponent [{:keys [initial-name]}]

  ;; use React Hooks for state management

  (let [[name update-name] (hooks/useState initial-name)]

    [:<>

     [:div "Hello " 

      [:span {:style {:font-weight "bold"}} name] "!"]

     [:div [:input {:on-change #(update-name (-> % .-target .-value))}]]]))

(react-dom/render

  ;; hx/f transforms Hiccup into a React element.

  ;; We only have to use it when we want to use hiccup outside of `defnc` / `defcomponent`

  (hx/f [MyComponent {:initial-name "React in CLJS"}])

  (. js/document getElementById "app"))

```

## Dependencies

You'll want to make sure you have the latest version of `react`, and whatever

renderer you are targeting (e.g. `react-dom`).

```

npm i react react-dom

```

If you want to use the React Hooks API (`hx.hooks`), you'll need to ensure

you are using React 16.8 or later.

## What problems does `hx` solve?

`hx` is meant to make it simple, easy and fun to use [React.js](https://reactjs.org/)

within ClojureScript. It is your bridge to the wide world of React.js in 

idiomatic CLJS.

The library is split into (currently) three sections, which you can feel free to 

mix as your project sees fit:

1. A hiccup interpreter. Takes in `[:div {:style {:color "red"}} [:span "foo"]]` and

spits out `React.createElement` calls.

2. Helpers for creating components. `defnc` and `defcomponent` help us write

plain React.js components in idiomatic ClojureScript.

3. Helpers for using React Hooks.

## What problems does `hx` _not_ solve?

No opinionated state management, no custom rendering queue. Use it to build

your awesome opinionated async reactive immutable app framework. `hx` is just

a Clojure-y interface to creating plain, unadulterated React components.
