In this post I will show you how to use SQLite3 directly in the web browser using the original C library through WebAssembly and OPFS to store the database. In this way we will have original SQLite3 on the web to work in the browser with JS on the client side.
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 there are millions of tutorials about MySQL and PHP, I decided to make mine but in a very very simple way. Before you start, you must have a basic knowledge in MySQL.
It is worth mentioning that we will not see good practices of databases, relationships, etc. We will use the tables as they are, without looking at normalization, or things like that.
Note: this tutorial uses PDO, but remember that we can also use
mysqli functions. Personally I recommend PDO, because it is object oriented. However, I hope to write a tutorial about mysqli in the future.
