Creating an API REST with Python, Flask and SQLite3

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.

In the end you will have an API that you can consume from any client that could be an Android application, a browser with JavaScript or even another server language.

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.


API REST with Go and MySQL

In this article about programming in the Go language (also known as Golang) we will see how to create a REST API that communicates through JSON, saving and displaying data from a MySQL / MariaDB database.

In the end we will have a REST API with Go using the 4 methods: POST, PUT, DELETE and GET using the Mux router. We are also going to implement the 4 operations of a database: insert, update, delete and select.

I will leave the full open source code at the end of the post.


How does the plugin for thermal printers work

A plugin for printing in thermal printers directly from browser

In this post I will introduce to you a plugin for printing tickets, receipts or invoices on a thermal printer using client-side JavaScript even if your web page or application is on a cloud server.

This plugin allows you to print directly from browsers, without dialogs and without browsers compatibility issues because you only have to send a HTTP request to print silently and in the background.
