Prepare a Sample Application

Let's turn a simple web chat application into SaaS

In this tutorial, a simple chat system created as a so-called ordinary web application will be converted to SaaS using the SaaSus Platform.

Preparing the Sample Application

First, let's start the sample application!

The backend of this simple chat system is PHP8 + Laravel9 + PostgreSQL13.
There are two types of frontends, one created with Laravel with Blade and one created as an SPA with Next.js.

First of all, let's check the operation!

In the directory where the above repository is cloned,

  • For PHP, under sampleapp-basic-chat/php/laravel
  • For Next.js, under sampleapp-basic-chat/node/express

will start the application locally.

Once it's started, go to the URL below and give it a try.

Blade version

URL: http://localhost/board Authentication Email:
Password: password


Next.js version

URL: http://localhost:80/login/ Authentication Email:
Password: password

  • The Next.js version may take several minutes to build. If it doesn't display, wait a few minutes and try to view it again.


In this way, users can write whatever they like.

Currently, we use Laravel's standard authentication module to identify users.

However, since it is a Laravel standard authentication module, it is difficult to say that security is strong. Also since it's a simple web application, of course there is no concept of tenants. There is no concept of roles, and there are no pricing plans.
