Test the powerful 4D REST server with Postman

Automatically translated from English

4D provides a powerful REST server, that enables direct access to data stored in your 4D databases. This makes it possible, for example, to build an API to use with a modern front end technology (e.g., Angular, React, etc). In this blog post, we’ll provide a first introduction to the 4D robust REST server. You’ll see how to configure it as well as test the create, retrieve, update, and delete (CRUD) operations using the API testing tool, Postman.

List box typeahead: Intuitive list searching

Automatically translated from English

by guest author Chris Belanger, a 4D developer from Canada

List box typeahead (a method for progressively searching) is not a native feature of list boxes. However, you can easily implement this feature with some creative coding. In this blog post, I’ll demonstrate the technique along with a database example and an exhaustive document explaining the details step by step.

The final result is summarized in the GIF below, It illustrates two “searches”. One for E-L-L-I-O-T, then another (after a column sort) for H-A-N-N-A-H:
