# Cypress Webpack Preprocessor (Batteries Included)

Cypress preprocessor for bundling JavaScript via webpack, with dependencies included and support for:

- Various proposal-stage ES features
- TypeScript
- CoffeeScript

## Why?

This preprocessor is a wrapper for [@cypress/webpack-preprocessor](https://github.com/cypress-io/cypress/tree/master/npm/webpack-preprocessor#readme). The webpack preprocessor does not include any extra dependencies (e.g. `babel-loader`, `ts-loader`), since most users will use their own `webpack.config.js` with it and already have the necessary dependencies installed. This preprocessor is for users who do not have those dependencies installed and would prefer not to configure the preprocessor to handle things like TypeScript and CoffeeScript.

## Installation

Note that installing [@cypress/webpack-preprocessor](https://github.com/cypress-io/cypress-webpack-preprocessor) is also required. This allows you to update its version separately from this wrapper.

```sh
npm install --save-dev @cypress/webpack-batteries-included-preprocessor @cypress/webpack-preprocessor
```

## Usage

In your project's [plugins file](https://on.cypress.io/guides/tooling/plugins-guide.html):

```javascript
const webpackPreprocessor = require('@cypress/webpack-batteries-included-preprocessor')

module.exports = (on) => {
  on('file:preprocessor', webpackPreprocessor())
}
```

This preprocessor supports the same options as [@cypress/webpack-preprocessor](https://github.com/cypress-io/cypress/tree/master/npm/webpack-preprocessor#readme), so see its README for more information.

## Contributing

Use the [version of Node that matches Cypress](https://github.com/cypress-io/cypress/blob/develop/.node-version).
