Tutorial: SQLite and Node-RED

This tutorial will show you how to make use of an SQLite database using the litedb node on the FRED hosted Node-RED platform to create database tables and store data. Under the hood, the litedb node uses SQLite.  As a very lightweight relational database, SQLite does not need complex setup procedures, making it an ideal database management system to use for embedded systems and rapid prototyping.

Node-RED: Lecture 5 – The Node-RED programming model

As you’ve seen in previous lectures, Node-RED uses a visual flow-based programming paradigm[1]. This is not unique to Node-RED. Similar approaches have been used in many other domains such as music and multimedia (Max MSP), toys (Lego Mindstorms), enterprise application integration and industrial automation (LabVIEW).
