This is a browserify development server inspired by [beefy](https://github.com/chrisdickinson/beefy) and [wzrd](https://github.com/maxogden/wzrd), but specifically focused on incremental reloading, LiveReload integration (including CSS injection), and other high-level features.

To install:

```sh
npm install budo -g
```

Running budo will start a server with a default `index.html` and incrementally bundle your source on filesave. The requests are delayed until the bundle has finished, so you won't be served stale or empty bundles if you refresh the page mid-update. Examples:

```sh
# serve file on port 9966 and open browser
budo index.js --open

# enable LiveReload on HTML/CSS/JS file changes
budo index.js --live

# pass some options to browserify
budo index.js --live -- -t babelify
```

Then open [http://localhost:9966/](http://localhost:9966/) to see the content in action.

By default, budo pretty-prints to terminal with [garnish](https://github.com/mattdesl/garnish).

## features

At a glance:

- stubs a default `index.html`
- fast incremental bundling, suspending the response until the new source is ready
- watches HTML and CSS files for changes; CSS is injected without reloading the page
- can emit [ndjson](http://ndjson.org) logs to use another pretty-printer, like [bistre](https://github.com/hughsk/bistre).
- provides clear error messaging during development in DOM and console

Below is an example of how syntax errors look during development, using the [babelify](https://github.com/babel/babelify) transform.

## usage

### CLI

Details for `budo` command-line interface.

```txt
Usage:
  budo index.js [opts] -- [browserify opts]

Options:
  --help, -h       show help message
  --version        show version
  --port, -p       the port to run, default 9966
  --host, -H       the host, default internal IP (localhost)
  --dir, -d        a path, or array of paths for base static content
  --serve, -s      override the bundle path being served
  --live, -l       enable default LiveReload integration
  --live-port, -L  the LiveReload port, default 35729
  --open, -o       launch the browser once connected
  --pushstate, -P  always render the index page instead of a 404 page
  --onupdate       a shell command to trigger on bundle update
  --poll=N         use polling for file watch, with optional interval N
  --title          optional title for default index.html
  --css            optional stylesheet href for default index.html
  --ndjson         print ndjson instead of pretty-printed logs
  --verbose, -v    also include debug messages
  --no-stream      do not print messages to stdout
  --no-debug       do not use inline source maps
  --no-portfind    will not attempt auto-portfinding
  --no-error-handler  disable default DOM error handling
```

By default, messages will be printed to `process.stdout`, and `--debug` will be sent to browserify (for source maps). You can turn these off with `--no-stream` and `--no-debug`, respectively. 

Everything after `--` is passed directly to browserify. Example:

```js
budo index.js --live -- -t [ babelify --extensions .es6 ]
```

### API

The API mirrors the CLI except it does not write to `process.stdout` by default.

```js
var budo = require('budo')
var babelify = require('babelify')

budo('./src/index.js', {
  live: true,             // setup live reload
  port: 8000,             // use this port
  browserify: {
    transform: babelify   // ES6
  }
}).on('connect', function (ev) {
  console.log('Server running on %s', ev.uri)
  console.log('LiveReload running on port %s', ev.livePort)
}).on('update', function (buffer) {
  console.log('bundle - %d bytes', buffer.length)
})
```

See [API usage](docs/api-usage.md) for details.
