Starting Qodly studio is just two clicks away
4D Qodly Pro offers all the tools you need to design, build and run web forms for your 4D application.
Fully integrated to 4D, it comes out of the box with Qodly studio. And just like 4D, its use is easy, accessible and nested in the 4D’s world.
To use Qodly Studio with 4D projects created with older versions, some project settings might need to be changed to support modern features.
That’s why, starting 4D 21, the access to Qodly studio from 4D has been enhanced to be no more than two clicks, to make your life easier, free your mind and let you focus on your business success story.
Localize your Qodly Pages: A Practical Guide
Localization of 4D applications has been supported for decades through the XLIFF architecture, designed primarily for desktop applications.
But browsers work differently.
That’s why 4D Qodly Pro introduces a new, built-in internationalization (i18n) approach—one tailored for web interfaces, giving you more flexibility when building multilingual Qodly Pages.
Let’s explore how this works in practice.
New Way to Control Your HTTP Responses
Starting with 4D 21, 4D developers can now take full control over HTTP responses using a simple configuration file: HTTPRules.json. Whether you’re looking to enhance security, optimize performance, or manage access to static resources, this feature gives you the flexibility you need, without writing a single line of code.
Let’s dive into the capabilities and how to use them.
Work and Move with QUIC and Network Switching
What’s more frustrating than losing your 4D Remote connection to the 4D Server while switching networks on the go?
Whether you’re moving from Ethernet to Wi-Fi or hopping between hotspots, traditional connections tend to drop, forcing 4D Remote to disconnect and reconnect.
With 4D 21 and the QUIC protocol, those interruptions are a thing of the past.
QUIC is designed to be resilient during network changes, keeping your session alive even when the underlying connection shifts.
Modernize your 4D interfaces with Fluent UI
Behind the scenes, a significant engineering effort has been carried out to bring native Fluent UI integration into 4D. This means that 4D forms can now be displayed using Microsoft’s Fluent UI design system, the same modern visual style that defines Windows, Office, and Teams. 4D is one of the first development environments to offer native WinUI integration, allowing developers to bring the authentic Fluent UI experience to their desktop applications. On the client side, the transition couldn’t be simpler. All it takes is enabling Fluent UI rendering in your project settings and making a few minor layout adjustments in your forms to enjoy the new, modern look.
4D NetKit: Secure OpenID Authentication with nonce attribute
When working with modern authentication flows, security is paramount. Developers often need to integrate authentication with trusted identity providers such as Google or Microsoft. This is where OpenID Connect (OIDC) comes into play.
OIDC is an identity layer built on top of OAuth 2.0. It allows your application to verify the identity of a user and to obtain basic profile information in a secure way. Starting with the latest enhancements to the cs.NetKit.OAuth2Provider class, 4D 21 now makes it easier to work with OpenID Connect by supporting the nonce parameter, along with new token attributes, including the id_token.
Trim, Trim start, and Trim end in 4D
When working with user input, data cleaning, or text formatting, one of the most common tasks is removing unwanted whitespace. Whether it’s a space accidentally typed before an email address or a newline character left at the end of a copy-paste, these seemingly invisible characters can cause unexpected behavior in your applications.
Fortunately, 4D 21 provides easy-to-use string methods to help: Trim, Trim start, Trim end.
4D NetKit: Decoding, Generating, and Validating JWT
JSON Web Tokens (JWT) have become a key standard for secure authentication and information exchange between systems. With JWT, you can transmit data in a secure, verifiable, and standardized way, reducing complexity while improving security. In particular, JWTs are essential when working with OpenID Connect, where they allow you to validate and decode the information returned by the OpenID provider.
Within the 4D 21, 4D NetKit provides a simple API to handle these tokens: decoding, generation, and validation.
Convert Numbers with Ease: Enhanced String and Num Commands
When working with different numeric bases, such as binary or hexadecimal, converting between numbers and strings is a common task. With 4D 21, the String and Num commands have been enhanced to make these conversions more powerful.
4D Developer Automatic Activation
Isn’t it tedious to manually enter license numbers every time you install your softwares on a new machine?
With 4D 21, that’s no longer necessary, 4D now does it for you automatically. Let’s see how.
