The files don’t have a structure, but like I said, it’s an example. I also write this because it either serves someone else or it serves myself for some references.
For data persistence it uses MySQL. This POS Save products and sales. It does not handle user permissions. We store the shopping cart in the session, and well, I better explain it in parts in this post.
Obviously this POS software is free and open source.
Today I am going to show you a software that I just made with Laravel. It is a sales system, point of sale, POS or whatever you call it, which is used to keep track of the products that are sold, the sales, and so on.
It is a totally free and open source system; which means that you can use it at no cost, and modify it to your needs or customize it. Among its features we find:
Now let’s see how I have developed it, where you can download it, and so on.
In this Python programming tutorial you will learn how to create a REST API using Flask, SQLite 3 (for data), and JSON for data communication.
I will show you how to create an API that communicates using JSON and saves the data in SQLite 3. The API will be created with Flask, and we will use the Python programming language to handle all the data.
Although it seems simple to do, it is one of the jobs that has cost me the most and of which I am most proud. It was complex (for me) to understand all the logic for collisions, rotations, row deletion, part movement, limits, etc.
Among the features of the game we find:
Let’s see then the details of this game programmed in JS. Throughout the post I will show you how this game is programmed, I will also leave you a demo and the complete code which is FOSS.
Note: figure, piece and tetromino will be used synonymously in this post.
