Node.js and Node Local Web Server Primer Tutorial<\/p><\/div>\n

We love PHP for web server work, but readily acknowledge …<\/p>\n

    \n
  1. PHP is losing out, in popularity terms, to frameworks like Node.js<\/a> (which we introduce to you today with a “Hello World” tutorial, where you’ll see its Javascript (yes, Javascript), in (server side) action)<\/li>\n
  2. Node.js is a framework that has Javascript running on the server side, a pretty powerful scenario<\/li>\n<\/ol>\n

    … and so, a great divide in programming (frameworks) is developing. Personally, I like the division of “language” between PHP server code and Javascript client code, but can see the “cuteness” of just thinking “Javascript”, and so, today, we show you a Node.js installation on our MacBook Pro using Mac OS X, though you will see, if you take a skeg at our slideshow<\/a> that Node.js is very much cross-platform by nature.<\/p>\n

    If you read this blog, you’ll (hopefully) have seen how fond we PHP’ers are here regarding the …<\/p>\n


    \n    MAMP<\/i><\/a> local web server on port 8888<\/i> supporting PHP<\/i> and a MySql<\/i> database on port 8889 on a MacBook Pro Mac OS X using web browsers
    \n<\/code><\/p>\n

    … well with Node.js, the scenario is …<\/p>\n


    \nNode<\/i> local web server on port 3000<\/i> supporting Javascript (Node.js like)<\/i> and a MySql<\/i> database (still) on port 8889 (in our case because we co-exist with MAMP and have MAMP running and access its socket file to make the MySql connection) if co-existing with (running) MAMP or port 3306 (it looks like) if there is no MAMP involved
    \n<\/code><\/p>\n

    And so, today, we first show a client “facing” “Hello World” scenario of just showing … “Hello World” … a web application “frontend” if you will.<\/p>\n

    Then we got a MySql database involved … a web application “backend” if you will … and we hope if you are a regular reader at this blog … even though this blog posting may have<\/i> “rocked your world” with (Node.js) Javascript getting involved at the server side (though we did warn you with our very first Javascript DOM focused tutorial called JavaScript and the DOM Tutorial<\/a>?! … it’s taken a while for the “wheel” to turn!) … databases always involve server side code, and so we update the hello_world.js<\/a> to include showing the results of our MySql query …<\/p>\n


    \nSELECT * FROM CIRCLE, POINT WHERE pointid=originid
    \n<\/code><\/p>\n

    … linked, “back in the day” with this MySql Stored Procedures Primer Tutorial<\/a> … and after some dead ends where we didn’t know whether to have MAMP running or not … the slideshow is “warts ‘n all” … we end up finding out that Node\/Node.js (Javascript)\/MySql<\/i> can co-exist and be an alternative to our cherished MAMP (local Apache web server)\/PHP\/MySql<\/i> “power triplet”. To have a few methods to try things can’t be that bad … huh?! Stay tuned please.<\/p>\n

    We (almost) leave you with the Open Source links that made the research (culminating in today’s tutorial picture<\/a>) possible … thanks …<\/p>\n
