Run with opal-node app.rb
or run the repl: opal-node-irb
Install with NPM: npm install -g opal
or via RVM: rvm install opal
``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 = require('http')http/server.rb
module HTTP
class 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
A simple Express.js wrapper example can be found in examples/express-wrapper.rb
`ruby`
Express.new do
get '/' do |req, res|
res.send 200, 'hulla!'
end
end.listen 3000
Start a coffee watcher to keep opal.js in sync with opal.coffee
coffee -cwo lib/ lib/*.coffee
NODE_PATH="$NODE_PATH:../lib/" node ./bin/opal-node
NODE_PATH="$NODE_PATH:../lib/" node ./bin/opal-node-irb
To keep the specs running while developing just install and use spectator
that will compile opal.coffee to opal.js` before every run of the spec.
$ gem install spectator
$ gem install notify # to get notification
$ spectator
