# Opal for Node.js

---

> **WARNING** 
> 
> This project is currently slightly outdated, the current preferred way to use Opal with Node.js is to compile the app and use node to run the compilation result. 
> 
> A `nodejs` file is now available directly [in the stdlib](https://github.com/opal/opal/blob/master/stdlib/nodejs.rb) and Node.js is also the default runner for the CLI (see `opal --help` for a list of alternative runners). An example of this can be found in [the `mspec_node` rake task](https://github.com/opal/opal/blob/master/Rakefile#L62-L63).

## Usage

Run with `opal-node app.rb`
or run the repl: `opal-node-irb`

### Installing

Install with NPM: `npm install -g opal`
or via RVM: `rvm install opal`

## Example ([rack](http://rack.github.io))

```ruby
# app.rb
require 'http/server'
HTTP::Server.start 3000 do
  [200, {'Content-Type' => 'text/plain'}, ["Hello World!\n"]]
end
```

This is the original Node.js example:

```js
// the original nodejs example
http = require('http')
var port = process.env.port || 1337;
http.createServer(function(req, res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello World\n');
}).listen(port);
```

Here's the (naïve) rack-like implementation of `http/server.rb`

```ruby
# http/server.rb
module HTTP
  `_http = require('http')`
  class Server < `_http.Server`
    alias_native :listen, :listen

def self.start port, &block
      server = new `function(request, response) {
        request.on('end', function(chunk) {
          var rackResponse = #{ block.call(`request`, `response`) };
          response.writeHead(rackResponse[0], #{ `rackResponse[1]`.to_native });
          response.end( rackResponse[2].join(' ') );
        })
      }`
      server.listen(port)
      server
    end
  end
end
```

### Example 2 ([express.js](http://expressjs.com) wrapper)

A simple Express.js wrapper example can be found in [`examples/express-wrapper.rb`](https://github.com/opal/opal-node/blob/master/examples/express-wrapper.rb)

```ruby
Express.new do
  get '/' do |req, res|
    res.send 200, 'hulla!'
  end
end.listen 3000
```

## Developing

Start a coffee watcher to keep opal.js in sync with opal.coffee

coffee -cwo lib/ lib/*.coffee

### Running in development

NODE_PATH="$NODE_PATH:../lib/" node ./bin/opal-node
    NODE_PATH="$NODE_PATH:../lib/" node ./bin/opal-node-irb

## Testing

To keep the specs running while developing just install and use [spectator](https://github.com/elia/spectator#readme)
that will compile `opal.coffee` to `opal.js` before every run of the spec.

$ gem install spectator
	$ gem install notify # to get notification
	$ spectator
	--- Waiting for changes...
