In this guide you can build a REST API with Node.js SQLite and Express.js. Then, in a next part, we will be building automated Unit tests using Mocha and Chai, ready for a Test-Driven Development (TDD).
The main components of this REST service are:
- A Node.js base project, created as a NPM module
- An Express.js web server to manage the API endpoints, requests and responses
- A SQLite database for application storage
In this guide we configure PHP and Laravel Framework to build web applications and REST APIs. As a result, you can prepare the environment to start the development process in a Laravel Project.
After this process, you will get installed the following components:
- PHP (PHP 7 or newer)
- MySQL/MariaDB server engine and client
- PEAR (PHP repository of common reusable components)
- Composer (PHP package and dependency manager)

In this post we will learn how to deploy your web applications in Heroku, for free. Heroku is a Cloud Platform-as-a-Service (PAAS). This company provides the base platform server, network resources and endpoints to publish your applications. However, you need to provide the application code and the rest is created automatically for you.
Sometimes, we need to test or showcase a quick prototype of a cloud based web application, REST API backend , or a static web application client. Heroku is a good solution to quickly host application at no cost. For example, they support the most popular languages and frameworks like Node.js, Ruby, Python, Java, PHP, Go, Scala, Clojure.
The general steps to deploy your application are:
- Register in the Heroku platform
- Install the Heroku CLI
- Login locally to Heroku
- Create your application and store it in a Git repository
- Configure your application for Heroku deployment.
- Register your application in Heroku
- Associate your git repository with your Heroku app
- Push your application to the Heroku application master repository
- Access your application from
