`reactR` provides a set of convenience functions for using [`React`](https://reactjs.org/) in `R` with `htmlwidget` constructor templates and local JavaScript dependencies. The `React` ecosystem is rich with components that can enhance `R` web and Shiny apps. `scaffoldReactWidget()` helps build `htmlwidgets` to integrate these `React` components as `R` `htmlwidgets`. `scaffoldReactShinyInput()` does the same for `Shiny` inputs. The local dependency functions are modeled after the `html_dependency_*` functions from RStudio's [`rmarkdown`](https://github.com/rstudio/rmarkdown) package.
## Installation
You can install reactR from CRAN with `install.packages("reactR")`. For the development version, please use `devtools` as shown below.
```R
# install.packages("devtools")
devtools::install_github("react-R/reactR")
```
## Creating htmlwidgets with React Components
To wrap a `React` component as an `htmlwidget`, please see the tutorial [htmlwidgets with reactR](https://react-r.github.io/reactR/articles/intro_htmlwidgets.html). Also, there are a variety of examples in the [react-R Github organization](https://github.com/react-R).
[`reactable`](https://github.com/glin/reactable) is a very well-built `htmlwidget` leveraging this functionality.
## Shiny Outputs and Inputs
`htmlwidgets` built with `reactR` work well in Shiny as outputs. In version `0.4.0` Alan Dipert has added the ability to easily create React-based official `Shiny` inputs with helpers and scaffolds. Please see the [tutorial](https://react-r.github.io/reactR/articles/intro_inputs.html) for more details.
## Examples
Below are examples of using `reactR` directly.
```R
library(reactR)
library(htmltools)
browsable(tagList(
tags$div(id = "app"),
tags$script(
"
ReactDOM.render(
React.createElement(
'h1',
null,
'Powered by React'
),
document.getElementById('app')
)
"
),
#add core-js first to work in RStudio Viewer
html_dependency_corejs(),
html_dependency_react()
))
```
`reactR` uses the `V8` package if available to transform `JSX` and `ES2015` code with `babel`.
```R
library(reactR)
library(htmltools)
browsable(
tagList(
tags$div(id = "app"),
tags$script(
babel_transform('ReactDOM.render(
Powered By React/JSX
,document.getElementById("app"))')
),
# add core-js shim first for React in older versions of RStudio Viewer
#html_dependency_corejs(),
html_dependency_react()
)
)
```
