Roadhog is a cli tool with `dev`、`build` and `test` commands. It's based on react-dev-utils and is consistent with the experience of create-react-app. You can imagine this is a configurable version of create-react-app.

## Docs

* [2.0 发布日志](https://github.com/sorrycc/blog/issues/55)
* [Migrate from 1.x](./migrate-from-1.x.md)
* [1.x docs](https://github.com/sorrycc/roadhog/blob/1.x/README_en-us.md)

## Features
* 📦 out of the box React application development tools, built-in css-modules, babel, postcss, HMR, etc.
* 🐠 create-react-app experience
* 🚨 webpack configuration in JSON format
* 🔥 mock
* ✂️ test based on jest (UI testing is not supported at this time)

## Getting started
```bash
## Install globally or locally
$ npm i roadhog -g

## Check version
$ roadhog -v
2.0.0

## Local development
$ roadhog dev

## Build
$ roadhog build
$ NO_COMPRESS=1 roadhog build

## Test
$ roadhog test
```

## Mock
roadhog dev support mock, configured in  `.roadhogrc.mock.js`.

e.g.

```js
export default {
  // Support type as Object and Array
  'GET /api/users': { users: [1,2] },

  // Method like GET or POST can be omitted
  '/api/users/1': { id: 1 },

  // Support for custom functions, the API is the same as express@4
  'POST /api/users/create': (req, res) => { res.end('OK'); },
};
```

## Use the public directory

Files in the public directory would be copied to the output directory (by default `./dist`) on the dev and build. So favicon, iconfont, html, html quoted pictures could be stored here.

## Configuration

umi's webpack part is based on the af-webpack's implementation. For configuration, create `.webpackrc` in the project root. The format is JSON, e.g.

```js
{
  "externals": { "react": "window.React" }
}
```

If you prefer JS configuration, or need to do some programming or abstract judgment, you can use `.webpackrc.js` configuration file, support ES6 syntax, e.g.

```js
export default {
  externals: { react: 'window.React' },
}
```

    children: true,
    minChunks(module, count) {
      if (pageCount <= 2) {

      }
      return count >= pageCount * 0.5;
    },

"copy": [
  {
    "from": "",
    "to": ""
  }
]
```

### proxy

Configure the [proxy] (https://webpack.js.org/configuration/dev-server/#devserver-proxy) property of webpack-dev-server.

```markup
"proxy": {
  "/api": {
    "target": "http://jsonplaceholder.typicode.com/",
    "changeOrigin": true,
    "pathRewrite": { "^/api" : "" }
  }
}
```

Then visit `/ api / users` to access the data from [http://jsonplaceholder.typicode.com/users](http://jsonplaceholder.typicode.com/users].

### sass

Configure the options for [node-sass] (https://github.com/sass/node-sass#options). Note: node-sass and sass-loader dependencies must be installed in the project directory when using sass.

### manifest

### ignoreMomentLocale

Ignore moment locale file, used to reduce the size.

### env

Set specific options for certain environment. `development` is for dev, and `production` is for build.

```js
"extraBabelPlugins": ["transform-runtime"],
"env": {
  "development": {
    "extraBabelPlugins": ["dva-hmr"]
  }
}
```

Thus, extraBabelPlugins in development is `['transform-runtime', 'dva-hmr']`, and `['transform-runtime']` in production.

## Environment Variables

You can temporarily configure some parameters for environment variables, including:

* `PORT`, default 8000
* `HOST,` default localhost
* `HTTPS`，whether to enable https, default false

e.g. start dev server with port 3000,

```bash
# OS X, Linux
$ PORT=3000 roadhog dev

# Windows (cmd.exe)
$ set PORT=3000&&roadhog dev

# Or use cross-env for all platforms
$ cross-env PORT=3000 roadhog dev
```
