What is Heroku? 

Heroku is a handy online service that came out in 2007 and is now part of the Salesforce.com family. Simply put, Heroku is a tool that helps you build applications without worrying about all the technical stuff.


Heroku, a cloud-based platform as a service (PaaS), is more than just a platform—it's your highway from idea to URL. This versatile service supports a broad range of programming languages and offers a robust ecosystem for developers to thrive.


Think of it like this: You're a star performer, and Heroku is your backstage crew, taking care of all the technical parts so you can focus on creating awesome apps.



Keeping Track of Your App with Heroku Monitoring

One really helpful feature of Heroku is called Heroku Monitoring. This is a set of tools designed to help you monitor how your app is doing and ensure it's working as best as possible.


Think of Heroku Monitoring as a safety net for your app. It gives you live updates on how your app is being used, how well it performs if there are any errors, and how many resources it uses. It's like having someone always watching over your app, ready to let you know if anything goes wrong.


Heroku's Compatibility with Other Technologies

One of the cool things about Heroku is that it can work with many different technologies like Node.js, Ruby, Python, Java, and PHP. This means that no matter what your app needs, Heroku can adapt to help. Plus, with its database service called Heroku Postgres and many other add-ons for checking your app's health, Heroku is like an all-in-one toolkit for app developers.

Why Should You Use Heroku to Build Your App? 

When you're starting to make apps, Heroku is a big help. Developers worldwide love it because it's easy to use, has many helpful features, and has a supportive community.


One of the best things about Heroku is that it deals with the hard parts of setting up apps. That means developers can spend more time doing what they love - writing code. It can also work with many programming languages and tech, so it's versatile.


Heroku has a lot of useful features too. It makes it easy to adjust your apps, update them, and return to an older version if needed. It also checks your app to make sure it's running well.


How To Create Your First App on Heroku

Making your first app on Heroku can be a cool and exciting project. Heroku's design is easy to understand, which is great if you're new to this. This guide will go through every step, in detail, to help you set up your app on Heroku:


Sign Up and Log In

To begin, you'll need a Heroku account. If you still need one, visit Heroku's sign-up page and follow the instructions. After creating an account, log in to the Heroku Dashboard.


Create a New Application

Once logged in, you'll see the "New" button at the top right corner of the Dashboard. Click it and select "Create new app." Provide an App name. This must be unique across the Heroku platform. Next, choose a region for your app. After this, click the "Create app" button.




Choose a Deployment Method

After creating your application, you'll be redirected to the "Deploy" tab of your app's dashboard. Here, Heroku provides multiple ways to deploy your application. If you don't want to use Git and GitHub, opt for Heroku Git (which involves the command line) or Container Registry.




Choose Your Language

Every app starts with picking a programming language. Heroku gives you many options like Node.js, Ruby, Python, Java, PHP, Go, and Scala. What you choose depends on what you need for your project and what language you like working with the most. For this guide, we will use Node.js, which many people use for making web apps.


Download Git and Run Installer

Git is a tool that helps you keep track of different versions of your app. It's really important when you're using Heroku. First, download Git from the official website and follow the steps to put it on your computer. After you've done that, open up your terminal or command prompt and check that everything worked by typing in:

git --version


Clone the Sample Application

Next, get a copy of a sample Node.js application on GitHub, and bring it to your computer. This is like bringing a completed model to your workspace where you can look at it closely and understand how it's built:

  • Navigate to Desired Directory: First, open your terminal or command prompt and browse through your computer's folders to find where you want to put the application. This could be any folder where you usually keep your projects.

  • Clone the Repository: After you've picked the right spot, it's time to copy the Node.js sample app. We'll ask the terminal or command prompt to fetch it from the web. Here's what you need to type:

git clone https://github.com/heroku/node-js-sample.git


  • Check the Cloned Directory: This command will create a new directory named node-js-sample in your current directory, containing the cloned Node.js application.


Define Procfile

The last thing you need to do before your app is ready is to tell Heroku how to start your app. This is done with a simple text file called a Procfile placed in the same folder as your app. Here's how to make one:


  • Create Procfile: Once inside the 'node-js-sample' directory, create a Procfile. You can do this using the command:

echo web: node index.js > Procfile. 


This command makes a new file called 'Procfile' right where you are, and then it puts 'web: node index.js' inside it.


Congratulations! You're one step closer to making your first app on Heroku.


Creating and Deploying an App on Heroku

After setting up your application, it's time to bring it to life on Heroku. Let's walk through these straightforward steps:


Log in to Heroku

Log in to Heroku by typing the following command in your command line::

heroku login


Once you execute this command, your web browser will open, allowing you to log into your Heroku account. You'll need to create an account if you don't have one.



Create a New Heroku App

After logging in, you can return to the command line, where you will receive a confirmation of your login. Now let's move on to creating an application on Heroku. To accomplish this, go to the directory of your application in the terminal. Execute the command: 

heroku create


Deploy Your App

Finally, let's deploy the app. Use this command 

git push heroku master


This command pushes your app from your local machine to Heroku.

Congrats! You've deployed your first app. To open it, type heroku open in the terminal.


Using Heroku Commands and Monitoring Tools

Heroku CLI offers various commands for managing your app. To see these, type heroku help.

You can also monitor your app's health and performance with Heroku's monitoring tools.


Making the Best Use of Heroku Monitoring Tools

If you want to monitor how your app is doing, Heroku's monitoring tools are perfect. They provide a wealth of information that can aid in assessing your app's functionality and resolving any issues. Here's how to maximize the benefits of these tools:


Heroku Metrics Dashboard: 

This is where you'll start when you want to monitor your app. It unveils data such as memory usage, response time, and data processing. Access the dashboard by clicking "Metrics" in your Heroku app interface.


Heroku Logs

Heroku Logs are like a diary of what your app has been doing. They capture everything from system glitches to user interactions making them incredibly useful for troubleshooting. If you type heroku logs --tail into your terminal or command prompt, you can see these logs as they're being made, which gives you an up-to-the-minute view of what your app is doing.


Heroku Add-ons

Heroku Add-ons are like helpful friends for your app. They're services made by other companies that give your app extra abilities. Whether you need detailed monitoring of your app's performance with New Relic APM, better ways to manage your logs with LogDNA, or a way to monitor everything your app is doing with Librato, Heroku Add-ons have got you covered.




By closely monitoring these tools, you can ensure your app runs smoothly and efficiently.



Getting to grips with Heroku and its tools for monitoring your app can make it much easier to develop successful apps. They simplify everything, so you can start building, launching, and managing your app without worrying about the complicated parts of launching and monitoring.
