how to build a cloud foundry app

In previous posts, we developed a small web application that runs in the cloud then we transformed it into an application that analyses given text and returns tone scoring per sentence. As we’ve been focusing on the functionality, the extended application was returning a rude output.

With most people judging a web app based on its look and feel, we’ll turn our bare application into something more presentable.

For this, we will use bootstrap as a CSS base and Perl HTML::Template to improve the overall readability of the code.

1. Build the Page Library

We’ll start by building a small library that

In this article, we will extend the simple “Hello World” routine that we created last week to more formal use. The cloud comes with many features, so we picked one that is called “Tone Analyzer”.

The Tone Analyzer service leverages cognitive linguistic analysis to identify the tone of input content enabling users to refine and improve communications.

We will use this cloud service to transform our basic “Hello World” application into an application that analyzes given text and returns tone scoring per sentence.

Let’s find out how to extend our basic application to use the Tone Analyzer.

Getting the IBM Cloud “Tone

In this blog series, we will develop a small web application that runs in the IBM Cloud. We will be using an old fashion way called rapid application development and an old framework called Plack, a Perl-based web service.

The purpose is twofold.  It demonstrates that traditional style environments can be used to build cloud applications and it also allows us to build a proof of concept in virtually no time.

Let’s get our hands dirty…

Hello world

So here is your basic application that does the usual.

#! /usr/bin/perl
use Plack::Builder;

use Plack::Response;

use strict;
sub main {

        my $env
