\t\t\t\t\n\/\/ these modules need to be imported in order to use them.\n\/\/ Node has several modules.  They are like any #include\n\/\/ or import statement in other languages\nvar http = require(\"http\");\nvar url = require(\"url\");\n\n\/\/ The most important line in any Node file.  This function\n\/\/ does the actual process of creating the server.  Technically,\n\/\/ Node tells the underlying operating system that whenever a\n\/\/ connection is made, this particular callback function should be\n\/\/ executed.  Since we're creating a web service with REST API,\n\/\/ we want an HTTP server, which requires the http variable\n\/\/ we created in the lines above.\n\/\/ Finally, you can see that the callback method receives a 'request'\n\/\/ and 'response' object automatically.  This should be familiar\n\/\/ to any PHP or Java programmer.\nhttp.createServer(function(request, response) {\n\n     \/\/ The response needs to handle all the headers, and the return codes\n     \/\/ These types of things are handled automatically in server programs\n     \/\/ like Apache and Tomcat, but Node requires everything to be done yourself\n     response.writeHead(200, {\"Content-Type\": \"text\/plain\"});\n\n     \/\/ Here is some unique-looking code.  This is how Node retrives\n     \/\/ parameters passed in from client requests.  The url module\n     \/\/ handles all these functions.  The parse function\n     \/\/ deconstructs the URL, and places the query key-values in the\n     \/\/ query object.  We can find the value for the \"number\" key\n     \/\/ by referencing it directly - the beauty of JavaScript.\n     var params = url.parse(request.url, true).query;\n     var input = params.number;\n\n     \/\/ These are the generic JavaScript methods that will create\n     \/\/ our random number that gets passed back to the caller\n     var numInput = new Number(input);\n     var numOutput = new Number(Math.random() * numInput).toFixed(0);\n\n     \/\/ Write the random number to response\n     response.write(numOutput);\n\n     \/\/ Node requires us to explicitly end this connection.  This is because\n     \/\/ Node allows you to keep a connection open and pass data back and forth,\n     \/\/ though that advanced topic isn't discussed in this article.\n     response.end();\n\n   \/\/ When we create the server, we have to explicitly connect the HTTP server to\n   \/\/ a port.  Standard HTTP port is 80, so we'll connect it to that one.\n}).listen(80);\n\n\/\/ Output a String to the console once the server starts up, letting us know everything\n\/\/ starts up correctly\nconsole.log(\"Random Number Generator Running...\");<\/pre>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
