# Webcam HTMLWidget

This example demonstrates creating an [htmlwidget](https://www.htmlwidgets.org/) wrapper around the [react-webcam](https://www.npmjs.com/package/react-webcam) library.

# Building

Because this package includes Javascript source code that requires a compilation step, package installation is in two phases: Javascript tools build the Javascript, and R tools build and install the package. The R package includes the built Javascript files in the `inst/` directory.

## Javascript Build Requirements

Building Javascript should work on macOS, Linux, and Windows. The following tools are necessary regardless of your platform:

- [Node.js](https://nodejs.org/en/)

- [Yarn](https://yarnpkg.com/en/)

## R Build Requirements

You should install the `reactR` package if you haven't, as this widget depends on it.

## Development Workflow

After you've installed Node.js and Yarn, run the following command to resolve and download dependencies:

```

yarn install

```

Now, run `yarn` to build `inst/htmlwidgets/webcamR.js`:

```

yarn run webpack --mode=development

```

> To run `yarn webpack` automatically whenever sources change, use the command `yarn run webpack --mode=development --watch`

Now that the Javascript is built, you can install the R package:

```

devtools::document()

devtools::install()

```

Finally you can try the example app by running [app.R](app.R).
