A New Server in 4D v20: WebSocket Server – Speed Up Your Web Clients – Thomas Maul

As it was recently announced, the next LTS release of 4D will offer a very powerful new feature… “4D v20 now includes a built-in WebSocket server, allowing developers to build real-time web applications that can handle large volumes of data and provide a seamless user experience.”

WebSocket is a computer communications protocol that provides full-duplex communication channels (bidirectional flow of data simultaneously) over a single TCP connection. Different from an HTTP server, which only responds to requests, a WebSocket server can not only answer but also push data to a client. Examples of where web WebSockets are used today that you might already be familiar with include chat applications and live dashboards that show current chart or device information, such as temperature of a machine or throughput in a factory.

Twilio Integration – Tim Nevels

4D has proven its capabilities for decades as a platform for quickly and reliably creating cross-platform applications with tightly integrated data backend services and creatively styled user interfaces. However one of the quickest ways you can impress with 4D is by demonstrating its ease of integration with other services. Not only can you use 4D as a web application and API server itself, but it is easy to connect to other service APIs to immediately leverage their features.

6 Changes to Check Before Transitioning to Project Mode – Erick Lui

The benefits of switching your older 4D application from binary (.4DB/ .4dbase) to Project mode are many and growing every day as new features are often released as Project mode only. Take advantage of classes, modern source control like Git, easier multi-version development, offline multi-user coding, native Apple Silicon chip support, and more.

However the leap to Project mode can seem a bit intimidating. Don’t worry! It is easier than you might think, especially if you get a few good tips before jumping right in. In this meeting presentation, Erick Lui will walk through some of the common tasks you’ll want to handle before making the switch.
