Extracted from [create-react-app](https://github.com/facebookincubator/create-react-app/blob/d1250743adc2abc41d80d566c5f817e1a16da279/packages/react-dev-utils/InterpolateHtmlPlugin.js)

## Install

This plugin is supposed to work with [html-webpack-plugin](https://github.com/jantimon/html-webpack-plugin/)

```bash
yarn add interpolate-html-plugin --dev
```

## Usage

```js
module.exports = {
  plugins: [
    new InterpolateHtmlPlugin({
      'NODE_ENV': 'development'
    })
  ]
}
```

Then you can use `%NODE_ENV%` in your template html file, and you can use it with html-webpack-plugin's default template syntax (lodash.template):

```js
<% if ('%NODE_ENV%' === 'development') { %>
do something
<% } %>
```
